Here's my situation:
I have a Yamaha RX-2700 receiver.
A friend gave me a couple problem subs. One was a Velodyne HGS10BG. Amp worked for a couple minutes after being turned on, then began crackling and stayed crackling. I replaced the caps but it didn't help and now the amp is basically dead.
The other is a significantly bigger Velodyne but I don't see model # anywhere on it. Amp is also dead. This one also now has a ripped cone (actually the foam outer ring).
Since neither have a working amp, what I am currently doing is running from the Sub Out of the Yamaha into an input on an old Onkyo stereo receiver, and from the regular speaker outs of that directly to the speaker of the sub (the smaller Velodyne since the big one is blown).
I saw the sale on the Epik Legend but was gutted when they sold out just a couple hours before I went to place my order.
So my question is, what should I do? How much difference would I see from my current jury-rigged setup to something like the Polk PSW505, currently at Amazon for $189, and in which direction? How big is the difference from the Polk to the Legend, which would be something like $650 with shipping whenever it comes back in stock (as opposed to $380 at the sale price with Discover Card promotion -- yep, I'm still just sick I missed it)? I see there is also the PA-150 at $425, the HSU STF-2 at $375.
For what it's worth, the front three speakers are Canton Karat CM4s. The surrounds are just the satellites that came with my initial HTIB, and are the only remaining elements of that HTIB that weren't replaced by donations from my friend.
I'd say $400 is my limit and I'd like to keep it well under unless this is something a layman would really hear a big difference in, justifying significantly more cost.
