PE Cnote Bookshelf Speakers Build
I decided since I am spending so much time in my office lately, I needed to build a better speaker system. Right now it has the polk RM8 surround sound system and they are terrible to say the least.
I will have about $200 total after I have them finished for the speaker build.
Here is an objective review of them from another site and seem very promising:
https://www.audiosciencereview.com/f...-review.12693/
I also added a 0.22 uf capacitor across L2 based on these results from PE tech forums Cnote Designer Chris P:
Here is before:

Here is after with 0.22uf: It knocks down the 7000hz to 10,000hz hump in the woofer.

Here are some pictures of the build so far:

This is the crossover design. It should be a 2nd order on the woofer and 3rd order on the tweeter if my understanding is correct:

I still need to sand it down, drill the 2" hole in the back for the round speaker terminal, and then I am going to cover it in white melamine. I wanted to try this stuff and this gave me an excuse:

Re: PE Cnote Bookshelf Speakers Build
I will also be using this to play with sigma studio more by using this Dayton Kernel dsp and 2 in 3 out board (~$30):
https://www.parts-express.com/dayton...-out--325-1300
This is very similar to what I would like to try which is the ADAu-1466 eval board from analog devices. Justin Zazzi uses it in his home theatre and has really good results. Andy W. also uses sigma studio for his entire car.

Or the 1467 which also has some cool daughter board options....

For whatever reason your google pictures aren't working. Other users of google pictures have had the same trouble in the past. Just shows up as a block with a gray circle in the middle.

Re: PE Cnote Bookshelf Speakers Build
Just out of curiosity, those that are having issues viewing the pictures, are you using firefox? I just tried that and none of them loaded. Same thing with safari....
So moral of the story...start using chrome ;)

Presently using chrome (still yet to de-google) and was able to view all of the images in post #1, yesterday at 2:30 - at which time I had clicked the corresponding Thumbs Up icon. However, since sometime last night - around the time of Justin's post about unseen images and subsequent attachments - each post #1 image has been replaced by an empty space with a gray circle icon in the middle.

Re: PE Cnote Bookshelf Speakers Build
Interesting. I hate the attachment part because you can only upload 3 at a time and can't rotate to get them to the right orientation :(.
Also, generally, the window size of them requires you to have to click on them....I would love to be able to adjust these things.
On the flipside, I thought the firs post pictures were too big and would have loved to size them down.
-
Re: PE Cnote Bookshelf Speakers Build
Yeah, for some reason, Google doesn't like being linked to. You could probably see it simply because you're logged into your Google Drive. I recommend Imgbox to host pics on.
-
Re: PE Cnote Bookshelf Speakers Build
Is there a better option for uploading files within the forum? Or does that create server space issues and better just to host them somewhere else?
-
Re: PE Cnote Bookshelf Speakers Build
I don't mind people uploading pics...especially if they're reasonably-sized. We will eventually run out of space, though, and I'll have to make a decision. Just don't upload a bunch of 8K images :thumbup:

Any way to get orientation controls and size controls for uploaded pictures? Like we can adjust the size and orientation in the post window.

Re: PE Cnote Bookshelf Speakers Build
I use GIMP to resize/crop. When you open a pic, it automatically makes the image right-side-up...you can then resize and save it. There no way of editing the pics in the forum software.
-
Re: PE Cnote Bookshelf Speakers Build
This seems like a PITA....
I really don't want to have to hose the files just for this site in another program/online storage site. Adding as attachments has its drawbacks of size and orientation.
Ugh.

Re: PE Cnote Bookshelf Speakers Build
I'm sorry...I'm just one guy running a forum. I don't have unlimited hosting and technical staff like that Verticalscope conglomeration. I have several monthly contributors who help pay the about half of the monthly hosting, but the rest comes out of my pocket. A couple of my buddies are admins who help keep an eye on the place, they can make basic changes in the admin panel, and they let me know when things go haywire....BUT, if something messes up, or someone is having technical issues, I'm the one who fixes it (or tries to). Right now, we've used about 70% of our disk space. If we get too big, we'll have to either upgrade the storage (more money), or start forcing people to host their images off-site.
-
Re: PE Cnote Bookshelf Speakers Build
I get it. I'd rather host the files from Google photos so it's a "web link" for you but the photo actually shows up without having to click an extra time. I know I am about 50/50 on having to go to another link just to see pictures.
But Google photos does not work...
I checked out the imgbox...not a huge fan of the dark color AND dark font choices...I can't do it..if you're going to choose dark background...then don't choose a dark font color!
-
Re: PE Cnote Bookshelf Speakers Build
Also, I do appreciate you coming here to even offer suggestions, we wouldn't get that elsewhere, which is why a lot of us are now here :)

Re: PE Cnote Bookshelf Speakers Build
Can you try using another hosting service? Imgur is good as well as the others that were suggested.

I switched the photos to imgbox, are they still not showing up?
Like I said earlier, if I use a hosting service, it is solely for this site. I'd rather not do that but will try some if I need to...I just love how Google photos auto backs up my photos with unlimited storage. And I don't want to use the site storage for reasons Al stated about storage.

Re: PE Cnote Bookshelf Speakers Build
You can use google photos to rotate, crop, and I think you can also export different size images. I usually crop/rotate on my phone right as I take the picture since it's easier.
I'm a huge fan of uploading to the forum so the images don't evaporate randomly in the future.
If none of that works, you are welcome to upload to my Smugmug gallery and link from there. You can use any size and upload as many as you want at a time.

Re: PE Cnote Bookshelf Speakers Build
Normally I crop and rotate on my phone as well when I take the picture, but I tried uploading photos with it rotated both ways and the results were unfortunately the same via phone and/or macbook. I didn't try google photos to rotate.
I get the point of uploading the photos and not hosting them and loosing them when a service decides to change their policies (which is why I like google photos because it seems to not do this type of thing), but I also understand Al's point of we will run out of space eventually, and I don't like how it makes the photos come out pretty small and you can't change that. So you have to click on them and make them bigger.
I've found most people have about a 3 click max unless they are REALLY interested in something. So one click to get to the forum, one click to get into the sub-forum they want to read, and one click to get into that thread has reached that 3 click limit. Having to click again is usually too much for most people.
Al, is there a way to make the photos uploaded show up in the post semi bigger? Like a default size thing that is just forum wide? I was thinking about double the size would be awesome. Build photos are ok the current size, but when people post graphs, it requires a click a lot of time to see the data. Then you lose the ability to see what they wrote about the photo so you have that stupid back and forth clicking and closing the photo to view photo then read the description, then view photo again, then read description again, etc.
The file size uploaded would still be the same, just the display size within the thread would be bigger. I can fix the rotation thing, that will just take a little work, but if the default view size was slightly bigger that would fix that issue too. Post 4 and 6 show forum upload forum display size (not actual file size). Post 6 illustrates the point the best with the graphs, in order to actually see the data, you will have to click on them and make them bigger, but the you may wonder which on is the 0.22 uf and which one is without, so you have to go back to the thread and read, then re-open the picture again.

Oh, that's what you're missing!
After you insert the image in your post, double click on it and change the size from "thumbnail" to "full size".
This picture below is adjusted to full size:

Re: PE Cnote Bookshelf Speakers Build
NICE! I did not know that about double clicking. I tried clicking and right clicking on them before but not double click.....
Now any way to set a default for this? I didn't find anything in user settings.

Ha! Me too. Thank you.

Re: PE Cnote Bookshelf Speakers Build
I think a lot of people did not know that....I always see pictures the small size. I like the Large and the medium! I changed post #4 to large and post #6 to medium just trying them out... I like the large size best comparing the two.
Side note:
Justin, can you see the pictures in post 25?
-
Re: PE Cnote Bookshelf Speakers Build
If post #25 has images for everyone to see, this might be the way you have to have google photos input into the forum.
Note: My old way was to just copy image and past image into the reply window. It has worked for me up until recently with this forum (at least nobody pointed out that it wasn't working...well at least until the new home sub thread)
New way:
Open google photos and open image in new tab
Copy URL
Open CAJ reply and click upload image from URL
Unselect the check box that says "Retrieve remote file and reference locally"
Should work then. That is how I posted in #25

Re: PE Cnote Bookshelf Speakers Build
Let me know if you have trouble viewing these pictures: I am trying the google photo upload way as I described in the previous post.
I tried the band-it Iron on White Melamine, and it didn't work well for me. I think it may be because it was 110 in my garage and just didn't cool down quite enough. The glue on the non-used stuff was kind of sticky still. This caused it to rip as I was trying to cut it.
https://lh3.googleusercontent.com/pw...-no?authuser=0
This was the glue that was left. Heat gun and scraper got most of it off, then goo gone for the rest.
https://lh3.googleusercontent.com/pw...-no?authuser=0
Glue removed and sanded back down and ready for primer:
https://lh3.googleusercontent.com/pw...-no?authuser=0
First Coat of Primer: I am using rust-oleum painters touch rattle cans and sanding in between every coat with 180, 400, 600, 1500 grit in opposite directions to get it nice and smooth for a gloss topcoat to hide any imperfections as best as possible.
https://lh3.googleusercontent.com/pw...-no?authuser=0
Sanded first coat and applied second coat of primer:

That may have been my fault. I added only some of the photos I wanted to the build album on my google drive. Then I deleted them and re-added (all except the sanded one as that was easy to know I already added it). I couldn't see them either.
I just tried again, let me know if they now all show up. I can now see them again.
Here is the full album on google photos:

Re: PE Cnote Bookshelf Speakers Build
Temperatures have made this a very slow go. Garage is over 90 in the morning and if I use my evaporative cooler, humidity gets on the higher side.
Sanding also isn't fun in those temps as the heat build up causes the sand paper to load up quickly. I purchased some better non-loading sandpaper (stearate coated) to help with that and have been attempting to only work in the mornings prior to work, but that leaves me limited time.

Re: PE Cnote Bookshelf Speakers Build
Finally getting some paint on these cabinets.
I put some on last Saturday but one of the spray cans starting spitting paint and forced me to sand the paint back down to primer :(. Luckily the new sandpaper works amazing! If you need good dry sand paper, the dura gold stuff on amazon is great! https://www.amazon.com/stores/Dura-G...0?ref_=ast_bln
But I have 2 coats on each cabinet now. Going to put one more of paint on before putting the clear coat on.
They are actually starting to look a lot like my vision for them. They will contrast my black gloss desk (I also built that) very nicely.

In this picture you can also see my great storage design for my garage, drop ceiling offering about 130 sq ft of storage space (11ft x 12ft) and then L shaped shelfs (18" x 12ft) on the left side and (3ft x 6ft) back. I then took a torch to them to give the boards some character. This was a great solution for garage storage! Only two vertical supports, the one you can see on the left and then one on the back and far right. Everything is hung on studs and then using joist hangers to hang all of the boards. The weight holding ability is crazy! Total cost was under $500 and then my time which was a couple days.

Re: PE Cnote Bookshelf Speakers Build
Those are definitely stunning!
Really like the storage layout too :thumbup:
