Any 15" DVC pro speakers out there?

[mr. doom]

I am looking for a high efficiency (98db+) DVC driver for a project. I know JBL and maybe Carvin had a sub cabinet loaded with DVC drivers but have not found a source for the raw drivers. Neo motors would be great but cheap would be better.

DVC pro driver? Not too common I wouldn't think. Little call for it. If you find one, please post it, It would be interesting to see. What do you plan for it?

 

[mr. doom]

Still in search of a DVC driver to run off a battery powered class-d amp and need a single unit that can draw the most "juice" out of a small T-amp. Dual 4ohm coils and high efficiency from 50-100hz would be perfect. Should probably post this in the subwoofer forum.

Thanks.

With all the new chip amps on the market I do not know why more efficient DVC drivers are not available for DIY. Most pro audio powered boxes have gone to 4ohm drivers in order to get 1000w out of class D amps.

only now an 18" dvc but is dual 8 ohm

why not take 2 *12"4 ohm drivers?

I heard of modified Eminence Kappa 10" to DVC 2x8 OHM.
Second coil is done by repair shop. The person who build sub is fully satisfied and I'm considering to build this sub also with Kappa 2x8 ohm.
Just realized that you are looking for 15" -belive that this can be done with 15" also.

Power level summation is not the most efficient way to go about it. You'd be better off going with a single power amplifier and mixing to mono at signal level, especially if there is not enough distance between the HF drivers to provide any sort of stereo image at the "listening postion" anyway.

every now and then, you can find some Cerwin-Vega Strokers. They were released for car-audio in the mid-90s, but they are "pro-audio" through and through. I just recently picked up a couple for $200, dual 2-ohm coils. The nice thing is that recone kits are available in single and dual coil configurations.

here they are, amongst the rest in my collection:

Why DVC and not SVC??

 

[mr. doom]

Maximize power available.

Why DVC and not SVC??

I used a moderately efficient DVC driver in another project and worked well. Better than the more efficient SVC driver with half the power.

A DVC 15" will help utilize what little power I have available with this project. Dual 4 ohm would be even better.

I was thinking I could fabricate a dual purpose bass bin that would run off a battery powered sure amp part of the time but also be powered by a regular pro amp. The box will be run from around 50-120hz.

Are you runing DVC as stereo subwoofer?

 

[mr. doom]

Yes

Are you runing DVC as stereo subwoofer?

Sure amps are not bridgeable to my knowledge and I would like to use both amp channels for one box. The design goals are to maximize the SPL from 50-120db in 200liters using only50w@8ohm/ 100w@4ohm per channel and keep the weight at a minumum.
