Subwoofer Power Amplifier Recommendations

I'm bi-amping a pair of 3.5 way speakers. Using a Joule VZN-80 tube amp to mids and tweets, but need an inexpensive SS amp to the woofers. Using a Marchand XM9 2-way electronic crossover & Marchand XM8 Basis. Specifics are:
- 2 Closed Box passive subwoofers
- Each box contains 2 Scanspeak 8 inch woofers
- Box Qtc = 0.731
- Driver Qts = 0.27
- Crossover to woofers @ about 80 to 100 Hz
- USE FOR AUDIO ONLY, NO MOVIES. Listen to folk, jazz, soft rock & vocals.

Question: Any recommendations for an inexpensive SS amp to run the subwoofers?
Do I need a low pass subsonic filter?
Will a 100 to 150 watt amp be sufficient?
Can I effectively use a standard SS amp or should I go pro audio equipment?
Thanks all, Jim

Thanks for the responses. The Behringer A500 has certainly made my list. Let me clarify a bit, not a big bass freak at all. Hoping for a seamless transition with the bi-amped Joule VZN-80 tube OTL amp on top to the SS woofer amp on bottom. The Marchand XM9 crossed over at about 80 - 100 Hz should help. Need just enough bass power to make this work. Now, thinking between about 150 - 250 watts/8 ohms per channel? Listen mostly to acoustic and vocals with an occasional rock interlude (usually when friends are over and then the wives tell us to turn it down). Also looking at some vintage stuff (Ampzilla, old Sony, Marantz & etc - reverting to my college days) but a bit afraid of reliability issues. Thoughts? Do the power estimates sound right?
Thanks again, Jim
