What amps are you using to power your passive subs? Both DIY and already made.
Soundstream DA-2 (1,000+ watts into 4 ohms). I've used it for multiple DIY subs (Adire, Dayton, BP 1803, AV15, etc.) and it performs perfectly. JP
The Soundstream DA-2=$+++. Also, what do you guys to to adjust the phase of your subs? Plate amps have phase adjustment but rack amps don't.
I'm using the NHT SA-3 (250 watts) with my Hsu TN1220... I have the Hsu Bass Optimizer to flatten out the frequency response down to 20 Hz. I am very pleased with the setup.
I was thinking of getting a QSC amp (cause they are cheeper) from a local store and using a BFD with it.
One of my subs has a bridged Adcom 555. 600 watts for $275 from a local want ad. Used home amps work great for subs. The BFD is a good idea... probably my next HT purchase. I don't believe it has phase adjustment, though. I've been contemplating building phase adjustment into my next DIY active crossover.
I'd like to build a component that has phase, dampening, and crossover adjustment for the subs. And I don't want to sum the bass signal but keep them left and right. Now, I don't know how to design to I'd probably have to have someone design it for me.
Carver A-760 600w/ch x2 into 4 ohms. Paradigm X-30 crossover for level and phase control as well as LF trim.
John, does that control unit adjust the phase for both the sub and sat or just the sub?
Sub only – which is what you want anyway. Regards, Wayne A. Pflughaupt
you can always switch the phase of your sub 180 degrees just by reversing your pos. and neg. leads.
I used a bridged pair of channels from a Cinepro 2K5II. 750 watts into 4 ohms.
Thanks Wes and Ray.
