Sub amp (1 Viewer)

[Jonathan T]

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.

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.

 

[Jonathan T]

Anyone else?

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.

 

[Jonathan T]

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.

 

[Jonathan T]

John, does that control unit adjust the phase for both the sub and sat or just the sub?

 

[Wayne A. Pflughaupt]

Sub only – which is what you want anyway.

Ok, thanks.

 

[Wes Goff]

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.
