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

Remember that bass uses the bulk of the wattage. With that said, you should have way more power available for the subs than the rest. Also, assuming that you won't have a dedicated subwoofer so the ".1" will be directed to your mains also means that you will need even more power.
I was going to offer my QSC 1200 but am thinking that you need way more power, maybe 300 per channel?
