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.

Your DIY sounds like a fun project. Which drivers did you use?

I own an NHT SW3p passive sub and have been considering some DIY projects with the NHT 1259 driver it uses for a possible stereo sub set up. I have the NHT SA-3 amp with built-in crossover. It works quite well, but I've had much better success using the Paradigm X-30 with a Bryston 4B. Although the SA-3 is made for the SW3p, the Bryston exudes superior control, pitch and extension. I'm only using one channel of the 4B which is easier on the amp, but may eventually use both.

The Marchand would be nice, but I can understand your hesitancy because of the price.

Yes, class G amps are capable of putting up big wattage numbers, but they're like cars that put out a lot of ponies but have no low end torque.
