4 "nsb" woofers from Partsexpress, $.49 each. To be run off the Sonic Impact T-Amp, which will be mounted inside this cabinet. 2 speakers per channel, stereo inputs, seperate volume control for each channel. Hopefully I'll have a cassette walkman guts in there for a distortion preamp for a decent standalone amp. Otherwise, the plan is to make my Pod XT audible without intolerable annoyance in the frequency response, while being accurate enough to let the tones of the Pod come to life at low volumes.
