Unfortunately the subwoofer is still stock and that's what I'll be changing next. I'd really recommend getting some different full range speakers. The z2300 satellites are like 3" full range drivers and have horrible midbass. These daytons get so loud off of 40w rms that I never have the volume above 50% any more; 15-35% is normal now. '

I'm tuned in to see how this goes because I want to do something similar :P

But the towers are probably also highpassed so that opens up an intersting problem.

I think the easiest way would be to go with the 2.1 plate I found and an 8" sub and completely replace the stock amp. Which is I know, the opposite of what I was saying before.

But I hadn't thought about the issue of there potentially being a HPF at say 40Hz to protect the old 5.25" sub.

The best thing to do is measure the frequency response of the subwoofer output and post it up. Then we can move forward.

If you post the voltages from 20-160Hz in say 5Hz steps we can figure out the response. don't do it full tilt, but close to it (don't clip the amp). I want to see if there's any bass boost etc going on.

If you don't want to go through that effort, go for the 2.1 ch amp.

Now the amp I haven't used, but it seems pretty decent

EDIT:

Wait, just use the amp in the towers for now. I doubt it'll be a weak point, in my experience the crappy speakers blow way before the amp dies. (well not saying your speakers are crappy so much as the amps are usually decent.)

Finding a 2.1 ch plate amp is possible, but under $150 will be tough. (impossible) And keep in mind whatever you do find needs a crossover for the sub. So using an old receiver is not an option without a crossover. Active crossovers are expensive.

If I was you I'd stick to the plate amp + sub and use the old speaker towers and their amp for now. When(if) it does die find used good 2 ch receiver to power the towers.

RE EDIT:

Ok I'll try again:

Dayton Audio MCA2250E 2.1 Channel Class D Amplifier 300-771

Dayton Audio DCS205-4 8" Classic Subwoofer 4 Ohm 295-200

Haven't used this sub or the amp however.

It works well vented.

And a plate amp too. That's within budget

All you need to add is an appropriate port and box
