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.

The discontinued Electron Kinetics Eagle 2 has superb grip and power in the bottom end. Unfortunately there are none for sale right now, but they do come up from time to time, generally in the $400 ballpark.

In the meantime, you might try wiring the drivers in your sub in series. While the wattage output of your amp will go down, the damping factor (control it exerts over woofer motion) will go up, and you may find it's a net improvement.
