Powering a Passive subwoofer.

Finally completed my prototype DIY sub. Has 2-8" woofs in parallel in a 2.3 cuft sealed box and front firing. I am using an old style plate amp at 70 watts. Sounds ok, but it can be better.

Choices are:
Adire or Kiego? plate amps.
NHT SA-3.
Get an Adcom,Hk or whatever amp with a X-30 box or a auto crossover. Probably get a good price on a used set up.
I would not mind, but what I would really like to try is a Bryston Powerpack 120 and a Marchland crossover. Little too expensive right now.

Any ideas, suggestions or experience would help.
My Audio Aero Prima integrated amp has a pre-out. My main speakers will be used from the AA, not the plate amp or whatever.
Thanks.

If you can find a Janis 1/a sub amp and crossover you would be happy. This is quite a clean amp. Only 100 watts @ 8ohms or 200 @4ohms but it extremely tight and by using its built in crossover (they don't get any better), you can blend it with the speakers perfectly. You can find one of these for around $250 if you search.

Janis was created for high end audio, not theater. It performs best from 20 to 100hz. I was amazed with the build quality and heavy guage internal wiring. Currently, I'm using it with Nelson Reed subs and don't even notice that I have a sub in the system-isn't that how it's supposed to work?
