Three years to get around to my own install.
Because isn't that always the way?
And actually - it's partly because I was leasing, but I love the car, so I'm just buying it out. Already installed heated seats which was a fun adventure.
They always start out so boring.
Stay tuned, giving myself two options out back.https://uploads.tapatalk-cdn.com/202...119e8a1e5f.jpg

Re: Three years to get around to my own install.
Sneak peek teaser - already pulled these out of storage and (literally) dusted them off.
Here's the two I'm starting with, to fit the tiny spot I'm willing to give up in the hatch - just the area behind the smaller fold-down seat.https://uploads.tapatalk-cdn.com/202...e2a06fabfd.jpghttps://uploads.tapatalk-cdn.com/202...b8dc5cf847.jpg

Re: Three years to get around to my own install.
Really excited for you!!! I hope you take us along for the adventure.
I had forgotten all about Earthquake, man i was a huge fan of their stuff back in the early 90's till i went team moon and stars

Two of them, since my intent is to try that box out with some pretty high excursion subs.
I'm sort of going into this install backwards, just based on what I have and what I'm still deciding. So - building the subs first.
I've been playing with PRs a bit in general... Had two (of my current favorite) eights with these 10" PRs in my last car.
Then I decided to make use of some of my other audio gear in my storage unit with this garage sale find antique radio. Actually have some great mids and tweets in there, Seas mids with Focal T90K tweets... With a super generic, relatively wimpy unmarked 12" sub that I think I picked up for like $20 at some manufacturer buyout sale, and used those 10" PRs that were on my shelves... Just a fun Frankenstein monster to make friends laugh - that actually came out sounding great. Even the sub, though it would be tighter with a better sub.
These 12" Earthquake PRs I bought because they actually seem engineered well. I like that they come with a mass ring (and a spec sheet baseline at that mass) that can not only be added to, but also removed and reduced - and look to have huge excursion capability.
We'll see how they actually perform, but Earthquake seems to stand behind them, pushing them, creating other products and official projects with them that they brought to trade shows - in my experience that's a sign of those "hidden jem" type products, so I'm optimistic.
I probably will end up building 3 boxes actually:
-- sealed, 1.25 cu.ft
-- passive radiators, 1.25 cu.ft
-- vented - TBD, but an intentionally generic compromise that works decent across my subs. I'd guess something like 2 cu.ft at 30hz.
I'll probably also swap in my Brahma 12, and probably pull a cheap or old school sub from the unit... I have an an ancient JL 12W1, just for fun comparisons. But that will have to wait until further down the road.https://uploads.tapatalk-cdn.com/202...d30016298d.jpghttps://uploads.tapatalk-cdn.com/202...ed75d72d95.jpghttps://uploads.tapatalk-cdn.com/202...ad9c322431.jpghttps://uploads.tapatalk-cdn.com/202...eddbd11dca.jpghttps://uploads.tapatalk-cdn.com/202...3f6ac865d9.jpg

Re: Three years to get around to my own install.
Wow haven't seen some Pro Tech subs in a long time. From what I remember those were really good sounding.
Love the old radio setup that would be a fun project to do.

Re: Three years to get around to my own install.
Geolemon,
I have an interest in learning more about modeling passive radiator setups with different subwoofers and since you seem to have a need or want to try those out and are not sure on the specifics yet, I may be able to help you with that? I have Bassbox pro and it has the capability to model different types and sizes of passive radiators. If you give me the specifications then I should be able to help you out? Bass box pro can also provide you with cut sheets that you can use as the basis of your design. Please let me know if you’re interested.

Thanks, it was fun - it sounds way better than I expected my "glorified bluetooth speaker" to come out. :lol:
How long ago did you hear of them? My history with them is pretty interesting-
They were a brand "back in the day", then they started to fade, and the original owner sold the company to an enthusiast who was running the company on the side, as just a fun little "lifestyle business".
I met him, Mike, coincidentally local to me, from my other ties in the industry back in the '00s.
I ended up doing some work with him when GE Capital sold an entire branch of business that I had been working in IT - he worked sales for an aerospace electronics manufacturing company, and got me a fun temporary job there while I idled a bit (had 8 months of severance pay from GE), and ultimately I ended up as one of three principal members of an SMT electronics contract manufacturing business also serving the aerospace company among others, which was a fun time for a few years, as I was the technical guy who programmed and ran all aspects of the robotic, automated SMT line. Google SMT pick and place machine, for fun. It's how circuit boards are made, although aerospace require much tighter tolerances and layers of inspections, than consumer electronics.
It was about the 1 year mark where the SMT business hit the $1M revenue milestone, so Mike decided to sell ProTech to focus on the 9-5 better...
...he ended up selling it to my very good buddy Rich. Rich kept some of the products going over time, and tried to work with the build houses to bring a few new products out (I was glad to help with that on a purely volunteer basis, this really was just fun, for both of us), but Rich was also going to medical school at the time (he's about 8 years younger than me, and was living in my basement apartment - I had just gone through a divorce so the roommate was great). Eventually it was just too hard to run - he had some local shops but of course 99% of enthusiasts only know brand names, and sales fell off (Mike was a much better sales expert). So today, there's not much happening.
In my storage unit, I do have a few ProTech subs - the 12 I've actually never used. The two eights - I did an install for a buddy of mine with eight of those eights, slot vented - it honestly was the "holy grail". It sounded good on everything. I own four of them, so maybe someday I'll do a half-size equivalent of that box. :lol:

Oh sure, what a great offer... WinISD pro has some functionality for that and I've done a little modeling, but actually I didn't specifically run some alignments. Does BassBox Pro have a driver database with sufficient details (beyond Qts, Vas, and Fs) for these subwoofers?
- JL Audio 12W7
- JBL GEI Mk1 12"
- Adire Audio Brahma 12 (mine is a 2008 version, but I think it's the same as current)
- JL Audio 12W0 (version 1... going back into history)
The T/S specs for these PRs (these specs are with the bolt, but without the mass disc):
- Fs = 25.5 hz
- Vas = 4.52 cu.ft.
- Qms = 7.0
- Cms = 0.38661 mm/N
- Mms = 289 g
- Sd = 483 sq.cm.
- Xmax = 4 in (doesn't state 'one way' so I'm assuming that's peak-to-peak)
The mass disc that it comes with adds 255 grams, but of course other washers can be added, in combination with or substitution for that disc.
As for the enclosure - I've built a box that will net 1.25 cu.ft., using the displacement of the GTi 12 and W7 12 which have nearly identical displacement.
The Brahma won't be too far behind that, probably will work out to be about 1.3 cu.ft... and for the W0, I'd expect net displacement to be about 1.4 cu.ft. It's a little guy. :lol:
I'd have gone smaller on the box but I actually want to have a direct comparison to a 1.25 cu.ft. sealed - and also because I don't want to have a PR exposed to damage risk in my hatch, I'm going to fire the sub forward, have one PR on the back side, and one PR on the top - so really the smallest I would have gotten anyways is maybe 1/2 cu.ft. smaller.
Interested in what you model up, thanks!

Re: Three years to get around to my own install.
I dont have as much of a history about Pro Tech speakers as you do. I do remember seeing them in a lot of the car audio magazines back in the day and as far as I know they were an in house speaker for PJ's Autosound in Erie, PA. I always wanted to stop in their shop but never had time as I used to go through Erie on my way to see my sister in Rochester NY. That's very cool you have a stash of their speakers and that slot ported box with 8 8's had to be pretty cool. I did get to hear a vehicle with 2 of their 12 inch subs many years ago at a show and was very impressed by them but I was also mainly a basshead back then.

You are pretty local to me - I'm just south of Buffalo, NY in Orchard Park.
As far as I know, PJs definitely was one of the biggest customers - and that may have even been the original owner who owns PJ's, I don't know. I only was introduced when I met Mike. I don't have much - for a very short time my old garage was the warehouse, but Rich moved out, I moved in with my Fiancee, and I sold that old house, Rich still has a little stockpile, but there's just not much.
Part of me would love to take it over myself, have my own little side-business - but I've done my time in the industry. :lol: Retail is tough, I have done that as well, managed a shop, made purchasing decisions - and while I personally always wanted to support the little guy, I recognize that 90% of the people out there would buy a turd with an RF logo on it at 200% of the price of a truly well-engineered subwoofer they've never heard of. That's just sad reality.

I wasn't looking to cause you lots of work - I do have some modeled.
If you want to validate or compare to these, that's definitely appreciated (especially since my W7 specs in my database at the moment are the minimal spec), but I'll load some of my graphs shortly, because there's some interesting findings already... :cool:

Re: Three years to get around to my own install.
So here's what I have so far - first the graphs, then the "experiments" [emoji38]
So you can tell "what is what", I made the W7 plots shades of blue, and the GTi shades of red.
For the signal, I put 600w - that's about what I'll give them (they each interestingly are 3 ohm nominal subs)
Frequency response:
Attachment 10793
Cone excursion:
Attachment 10794
Impedence:
Attachment 10795
**The sealed are the dark red and dark blue. Both totally normal.
**The PR are the brighter red (GTi) and blue (W7) I'm glad I didn't go smaller than 1.25 cu.ft... because even with the mass disc attached it's the equivalent of maybe a 38hz tune.
...I'll be playing with how much mass I need to add to get that closer to 30hz. Hoping to stay at 1.25 cu.ft.
**I modeled a "normal" vented box - the orange/red (GTi) and teal-blue (W7). For that, as expected I literally have to double my enclosure size.
I modeled up 2.35 cu.ft. vented at 29 hz (literally double the net size, with port displacement).
Interesting stuff:
--38hz tune with huge PRs? I didn't even think that was possible!
Makes me want to include a 38hz vented box with a "bigassports" vent and do an SPL comparison, too... We'll see.
--For "king of the hill" subs that have massive excursion capability - we're barely taxing them here!
That's not totally a surprise with these small-ish boxes, but note even if I *quadruple* the sealed box to 5 cu.ft., you finally cross the W7 Xmax at 25hz... and even then only if I nearly double my power to the full 1000w limit.
--It could even be said that these particular subs are somewhat of a waste for these applications... Which is one reason I wanted to start with these, then shuffle in some more "average" subs.
It's possible that they'll not only keep up with these, but if more efficient (as less capable subs frequently are) - surpass these in some ways! :cool:

Interesting - do you know what's off with the specs? WinISD took them, maybe Bassbox has some validity checking that WinISD doesn't? Those are just from the spec sheet they came with - and note that doesn't include their 255g mass disc.
I am surprised at *MY* plot that shows the PR tune is effectively so high...
I dismissed that just because of the small size, but we'll have to see which plot is right!

Re: Three years to get around to my own install.
Not yet but I can figure it out if I put my head to it. I already shut down the old laptop but can fire it up again tomorrow. Just off the top of my head the fs or the Mms in grams was off. Either the fs wanted to be 15 or the Mms 100 ish grams. Also your plot is higher because I think you used two PR and I used one.

Re: Three years to get around to my own install.
So here's a fun dilemma:
I want to be able to swap several subs back and forth into these boxes... and of course, each sub has it's own cutout.
The biggest - 11.125" cutout for the classic 10 spoke basket that I have on some prototypes and the Adire Brahma.
The smallest - 10.5" cutout for the 12W7... didn't expect that would be THAT much smaller.
My initial thought after measuring the JBL GTi with a pair of giant calipers is that I thought I could get away with a 10.75" cutout and that would be good for both the GTi and the W7 - and then I could make an adapter ring for the 10 spoke basket subs, with the taper of the frame it would fit fine.
Problem is - my giant caliper doesn't have giant arms, so I was trying to gunsight it down the arms - and clearly I measured wrong. The 11" cutout listed in the GTi 12 spec sheet must be actually legitimate...
So we'll flip that plan. I'll cut the holes at 11.125, then make an adapter ring for the W7 at 10.5". No biggie, other than "spacer + big excursion" is going to mean I need some real clearance in front of these boxes.
...in actuality, it could mean "easier swapping", because I can make a ring that the 12W7 stays permanently mounted to, and then I can just swap that whole assembly out.
Attachment 10852Attachment 10853Attachment 10854
I'm also going to try something that I think will just add a touch of professionalism to some otherwise boring, carpeted boxes.
I hate visible carpet seams, so I think I'm going to work some trim - maybe aluminum stock - in kind of a frame, an inch or so inside the outer perimeter of the sides.
That'll give me a clean set of lines to carpet to.
This is a home product and not the aluminum I have, but the picture is the closest thing that I can find to what I'm thinking, but just as an accent separating black carpeting from more black carpeting:
Attachment 10855
I also hate visible wires, which is going to be a challenge since I'd normally mount a terminal cup on one side or the other, but in this case I want the option to fire the box either forward or backwards, without having the wiring be visible - which pretty much leaves me the bottom. So I'm thinking about how to pull that off without spacing the box off the floor.
I'm leaning towards routering a groove all the way across the bottom, drilling a hole for a wire to exit the box (on either side, if I decide to reverse it), and then having a quick disconnect on the speaker wire path. To me, that's a lot better than a terminal cup on the speaker box, where [if disconnected for any period of time, to remove the box to use the hatch, etc] there's that risk of the two wires touching themselves or any metal, and presenting your amp with a dead short.

You could use the routered groove across the length of the bottom as you suggested. Attach XT60 connectors at the end of the wires and put a press fit notch into each end of the channel. Put a couple wraps of decorative tape along the wires to press fit them into the channel as well. Bam quick end-to-end wire relocation.

Re: Three years to get around to my own install.
I saw that Steve Meade has a magnetic speaker cup so you could mount one on either side maybe? Not sure if that'll do what you need but check them out.

Re: Three years to get around to my own install.
Actually both of those are pretty slick ideas.
The old wire and connector is probably less slick but easier - but maybe if I did both, with the magnetic coupler instead of the plug...
Hmm... :wink:

MD QR-1 Quick Release Speaker Box Terminal
Be the first to review this product
$129.99
IN STOCK
SKU 1-channel-NEO-Terminal
The SMD QR-1 Quick Release Heavy Duty speaker box terminal cup is a great solution to 2 common problems. One being that most terminal cups are very wimpy! Not this one! Rather than a very thin injection-molded unit like most others use, ours has a 1/2" body and 1/4" thick flange milled from 3/4" HDPE, this product will never crack or deform under pressure. The terminals we use are made of nickel-plated n52 neodymium magnets. They will never move OR leak! 100% Guaranteed not to "vibrate off" from any vibration of any sort. Of course, we use only the best Dual 10ga 100% OFC speaker wire!
The next problem this product solves is, of course, removability! If you live in a place you need to bring your box in at night, or perhaps to make room in the trunk for other items, now you can do it in a snap!
- CNC Milled 3/4" HDPE (1/2" Body, 1/4" Flange)
- 5' ft 100% OFC 10ga Speaker Wire. Can fit 8ga as well! (If selected)
- 1/2" Aluminum or Copper terminal blocks w/ 5/16" x 18 set screws (fits up to 8ga wire)
- 8 Mounting fasteners included (Dealers may vary)
- N52 Neodymium Magnets. VERY strong.
- Cork gasket ready to go!
- CUT OUT DIAMETER - 2.75"
- FLANGE DIAMETER - 3.80"
- Available in several different color combinations.
- Made with pride in California, USA
- Lifetime warranty!

Re: Three years to get around to my own install.
The Banana plugs or similar are definitely more on the budget friendly side...
The SMD ones - I mean, it's just the price that's crazy there. If I were going to do one install with possibly four hot-swappable boxes, I'd actually need four of those - that would cost me over $500 just to make connections?
On the other hand, I'm a fabricator (as are lots of mobile audio installers) - I hate to say it, but he's priced these right in "backfire" territory...
I think I may already own a bunch of these - I use them generally for holding trim panels in trunks without visible fasteners: https://www.amazon.com/VNDUEEY-Neody.../dp/B076GWZK99
The rest is just some thicker ABS - even just scraps out of my scrap heap are likely big enough, ABS glue to make layers into a cup and plug (which I think would look better than his routered solution here), or if I wanted to be really slick I could 3D print something that actually looked better than this. Crazy.
I say "backfire territory" because it's one thing to be a craftsman and leverage the advantage and investment into specialty tools - but when you cross the line when someone could actually buy the very specialty tools that you are counting on them not having, then to me that's like a personal challenge. I could 3D print these - including the full purchase price of the printer - for LESS than buying four.
All it takes is one person who 3D prints it and makes the files available free, to make this little profiteering venture tank quick. Bad business strategy, IMO.
I kind of like the idea now of making my own... I think this might just have to happen. :thumbup:

Re: Three years to get around to my own install.
Yeah... but they won't have SMD branded on them. ;)

Re: Three years to get around to my own install.
To be honest, I can actually think of a big way to improve that design. It's a little unsafe the way it is now - no issue if you are connected to a box, but let's say we removed it to drive to the hardware store. If that wire was connected to an amp, and those magnets either were attracted to chassis metal or something metal that just happened to be in the trunk, the magnets would TRY to pull that metal tight against the contacts, making for a short - bye bye, amp. Maybe even a fire, some amps don't have short protection. That would be fun to find, as you are driving down the road, wouldn't it?
I suppose you could install an inline fuse on the speaker wire specifically for short protection, but that's a little unusual.
It wouldn't be rocket science to create a divider wall that extends out from the surface of the plug, to mate into a corresponding groove in the socket plate - or, a groove/divider wall pair on both that both mate up. The latter idea would protect both AND ensure polarity.
Then if the connector was attracted to something metal, it would stick to one magnet or the other, and the dividing wall would keep that from making contact with the other, at least in most cases.
Or a rim ring / moat circling each connector that mate up... You could design that to be polarized or non-polarized. I'm just not liking that the SMD ones don't even try for safety.

Re: Three years to get around to my own install.
Yes Geo, I agree these are crazy expensive. I saw them on a video a while back but never knew how much they cost. I put it out of my mind since I really had no use for them until I saw this post. When I put it up here I was like, oh a picture would be good, that's when I went on his site. I agree they're way too much, but one invaluable thing here is, you got an idea that is sparking a thought to come up with something, that price isn't really all that quantifiable. So even if this doesn't work out, by reading what you put up here, sounds like you may have the makings of either a product for others or at least one for yourself that will be of service for your needs. If you do come up with one, I may be interested. I have a 4runner I'm doing for my daughter and the possibility of removing the box is there. Yes banana plugs would work, however this idea or likened to it would be a lot better. let me know if you do...you got about three weeks...lol

Re: Three years to get around to my own install.
Sweet, post a link to the files here and I’ll print one too for my new box lol. It can say CAJ on the side instead of SMD.

I just want to buy two of them.

Actually a joint effort might be pretty awesome, if you would be willing -
I'll have to play with tinkercad a bit, maybe I could pay you to print them in the short term? I know the filament isn't free.
I've wasted too much time looking for ABS sheet that is NOT textured on one side - thinking that actually doesn't exist. Could get smooth black PVC sheet stock but I'd have to order it...
...but how much cooler could 3D printed look than routering and laminating parts? :D
What do you think?

Re: Three years to get around to my own install.
I actually did a little CAD work on this last night, I think I have a workable baseline started. Maybe I'll finish it up by the weekend even.
Worst case, a 3D printer has been on my short list for a while, and I've been narrowing down the list.

I can’t mass produce them. I get away with printing stuff here and there at work, nothing too crazy. If you wanted to send me a file I’ll print one and send it to you no problem, but I’m in no position to mass market these.

Keep me posted, I want 2 of them! Unofficial CAJ swag! That'll look great on my box!

Interesting. I am currently a product line manager in charge of electronics development and manufacturing for my company. I have 3 plants running 4 SMT lines each 24/7 in Juarez MX, Budapest HU, and Shuzho CN. We are about to commission new plants in Toluca MX and Changsha CN. We are currently at 25 million automotive ECU's a year moving up to 40 Million by mid 2021. Covid-19 has us severely limited for now but we should be going full tilt again by August.
Yeah, I speak the lingo :).
