Sub Amp

[puckmasterc]

I have 2 passive B&W subs, THX PCS8 rated at 200 watts and no longer in production. I'm looking for a new amp to drive them. Just would like to get some others input on this. Considering the XPA-2 or 2 UPA-1's.

I'm using a UPA-1 to drive a subwoofer I built. I'm using this Tang Band driver:

www.parts-express.com/pe/showdetl.cfm?Partnumber=264-897

It's rated to 500W RMS, the UPA-1 has no problems driving it to ridiculous levels.

I also have a pair of passive subs, Boston Acoustics X595 THX

If you already have an Emotiva power amp with an unused channel, go ahead and use it to power your passive sub, but it would be a waste of the Emotiva amps to only drive a sub woofer. There are far less expensive amps available that were designed to run at the relatively restricted frequency range.

+1 to what roadrunner said. Here's a perfect example:

The subs wont care what name is on the amp/amps as long as they are getting clean power and the amp can handle the load.
Edogg points you to some good deals on some

I did find a sub woofer amp that has some nice features.

Also for the same price i can get this crown amp.

I have been using an older Yamaha MX-1000 amp to power the subs, but i think they just need more power.

Anyone have experience with the Dayton sub amps?

[shayking]

be careful with the parts express/Dayton subwoofer amps they all have a 20hz cuttoff circuit, which cant be overriden without a moddification

i have 500watt Dayton plate amp just collecting dust, becuase of that reason.

But some folks/ sub designs like/need the 20hz cutoff.

You really only need one UPA-1, it has 2 sets of binding posts and will put 175W into each sub (which only handle 200W).
