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.
