the first one was a circle, this one a racetrack. this one doesn't have much of a helmholtz chamber, its more of a tapped pipe with a stepped s3. whatever the case, it seemed to work well. these low motorforce 12's like a lot of breathing room to operate, thats why its so big. one thing i dont particularly like about these deaf bonce apocalypse is their rather atrocious motor and cooling noises. they squeak loudly. so it was nice to have the motor on the other side. honestly aesthetics was what initially motivated the port shape, then it was carefully adjusted for port velocity and removability of the drivers since it is the only access to the inside of the box. that and the 3d printed terminals i made.
Took the money from that sale and bought a couple amps
Right now I’m working on some ath Tritonia speakers. They’re about 70 liters with 12’s tuned to 50hz for a nice bump around 75hz. I want them to match nicely with my hroar for about a 9db gain in the bass region.

I need a dual 4 ohm woofer to accept both channels of the internally bridged nx6000. I found a motor online for 50. The motor without the basket is 60lbs. Soon I’ll have a pile of parts and some glue, and then hopefully a functioning subwoofer.
So you will connect the nx6000 in normal mode, loading channel A with one coil and channel B with the other coil
So channel A and B at 4 ohms
So channel A and B at 4 ohms
NICE model! I really like how that design looks.

Yes. One channel per coil. Probably the best (and least used) feature of dvc subs. You can do this with any 2 amplifiers by gain matching. Typically these full bridge amps are cheaper than half bridge aka “strap-able” amps.
Do you tame it a bit with dsp up top or is it pretty relaxed with the ‘weaker’ motored drivers?
It still has the rising response to about 85hz which is great for a car. overall sound is less punchy from what I could tell. Unfortunately I didn’t get the chance to dial it in for him. They were new woofers so I’m sure when they break in they will come into their own. If I can find the measurements and hornresp I took I will post them.
First horn printed and new powder coated basket attached. Waiting on the soft parts still I only ordered them yesterday. I bought a 4 layer progressive spider and a 4 layer 2.87” winding width vc. The long coil should increase bl at higher excursion. The stiff spider should give me a lower vas. I’m shooting for a qts of around .5. I’m deciding if I want to print a spider spacer ring to put the spider directly beneath the cone for linearity. Kind of fun designing woofers when you know what you want.

You sure do nice, clean fabrication work mister 👍🏼
the predicted output of the monitors with a captured prediction of the subwoofer, both at peak spl with filters applied. you can see why i wanted a boost in output there. this should follow my preferred house curve plus a couple extra db.
