In other news... I have started to make use of a spare set of sb acoustics 17cm mfc drivers I got at the start of this project, they will be installed in 14l ported bookshelf’s for at home alongside some of the budget sb acoustic 19mm tweeters... to be run off a genesis 4 channel (series 3) I picked up and a helix mini dsp for timing and eq/crossover dutys along with the regulation tea making equipment also

Nice, I have a set of these sitting in my office to go into something similar. Mind sharing a little more of the details of the build? rear port? What is it tuned for? I was extremely impressed by these drivers and tweeters for the money.

I'm curious as well - consider me another one all aboard the SB Acoustics train.

The plan was build them and add a port at a later date... they are a sealed enclosure with a Q of 0.5, this then made way for porting with a 200mm 50mm port as a natural progression, however with eq I have been able to get them to sound very nice and they are now flat from 45-20k give or take, and very good off axis also

so porting (they would be front ported also as eventually I will place them in a small room closer to a wall than rear porting would be good for) while it would be nice for some free bass I think accuracy is far more important and the desired aim

I have a applied a shelf eq to bring the midrange above 160 down 5db as being sealed there is a natural roll off, and also baffle step correction which causes a natural roll off around there also... then some eq from 0db at 8khz upto 3db at 20khz in a straight line... it is flat at the speaker, but further away at the listening position it rolls off a little bit

i set the crossover and delay approx 12” from the speaker (it needed 3.something cm off the top of my head in the mini dsp to align the two drivers) and I have used 2.5khz with 12db butterworth slopes and a little eq to remove the 2.5khz bump created

Very Nice... Yeah I would like to do something similar, possibly with a front port, or a PR, but build it sealed first. Thinking of a MiniDSP and a simple 4 channel amp.

It’s begun...

hybrid 6x9 out... sb acoustics satori 9.5” in... under each front seat...

[dumdum]

Small edit is possible with steel... fixed some extra holes as I snapped a tap on one baffle, and drilled several holes on the other baffle to extract another tap...

[preston]

Excellent.

Also jealous, there was plenty of room to do similar under my driver's seat, but a 1.5" channel encapsulating 4 different steel fuel lines and some extra junk under the seat dealing with air bag weight sensors rendered that plan unfeasible.

[BenevolentDictator]

That looks awesome. Waiting with baited breath about how those 9.5s work/sound in that location.

Welding done, chassis rail is immensely strong now with a piece of 3mm box section welded into it... and the 10mm baffle has been welded into the floor now also... in future once I know if the 9.5” are good enough I will add a piece of box section across behind the 10mm steel baffle, but just incase I need to go to Dayton rss285hf I won’t properly finish it just yet... but it will get some polyurethane sealant and some deadening added before it plays on Thursday at some point I think plus some carpet as an under layer below the factory carpet... I may also add a few layers of 10mm carpet underlay and sandwich some MLV between the two layers as well for good measure... but that’s for later... for now, onwards with the other side

just to illustrate how much space I have... there is a pic with a hybrid clarus 12 under the seat

So now I’ve had a few more days and slacked with the pictures...

so the satori 9.5” are in, a bit of eq and a rising curve upto 30hz sounds the most natural bass and lovely midbass I’ve heard, it definitely doesn’t take lots of power but would be ok for EMMA levels just I think... as you can see I have a crossover at 23hz 24db to cut stuff off below 30 which is fine for Emma

however I would like more... if they work well enough upto the 160 crossover I will end up with a pair of hybrid audio clarus 10” by Wednesday, and a very animal set of midbass to go with the Dayton RSS390HF subwoofer for heavy daily use and play anything in sq mode also with clean lows! The satoris nearly do it... sooo close! I am not one for tailoring my demo playlist to a list of stuff it will play... but if I was that way inclined I could find a nice selection of tunes I think...

also I had a lot of feedback from the steel frame of the seat... this wasn’t nice, so I took seven hrs and stripped the seat and deadened it as well as I’ve deadened anything in my life, insides, outsides and then packed the back of the seat with melamine foam...
