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.

Thanks for the responses, I sure appreciate it. The woofers are Zetagcorp 8" used in there G4 speakers. They have a cast frame, copper magnesium cone and rear vented. I bought these for close to nothing just to experiment with. I have a pair of Kinima G1 which sound fantastic; I just want a little more bottom end. My plan was to make a stereo pair, but the room is to compact for it. The only way to make a stereo pair was to make them 27" high and put my G1s on them. That meant getting rid of my Osiris stands. Not yet.

Well the idea of a class G amp is history, so it looks like getting a AB power amp and a X-30 or auto crossover.

Again, thanks for the responses.
