My current subwoofer just died and I'd like to build a 3Pi sub.
I'm wondering about the input/output wiring: in my current setup, a 2 channel tube amp feeds into the sub and then from the sub the signal goes to two speakers (just left and right channels). Will the 3Pi be able to do something similar? If not, what should I do for the configuration/wiring of a stereo (2.1) system?

It's a passive sub, so you need an amplifier and crossover. Many people use a plate amp and attach it to the loudspeaker cabinet, effectively making it an active subwoofer.

All speakers are ultimately passive devices, being a linear motor attached to a diaphragm. They are all driven by an amplifier of some sort.
I wouldn't run subs with tube amps even if my mains were run on tube amps. However, one of my personal systems uses SET amps for the mains and single-ended FET amps on the subs. I find that a good synergy.
Understood, thanks Wayne. So, just to be clear: what comes with the three pi subwoofer kit and what else will I need? (Besides the cabinet material and tools).
Also, does a plate amp include a crossover or will I need to build a separate one? If so, can I buy all the crossover parts together with the kit?
Excellent!
Could I ask you for a recommendation regarding the plate amp? Also, I'm located in Ontario, perhaps you are aware of online shops here in Canada where I can find one?
