Well, finally got the preamp working (with a lot of help from my friends).

The next project is to build the Pi Seven Theater Series cornerhorns. Since I do my sanding outside, it's time to get started.

Before ordering Eminence drivers, I'd like to determine if any of the woofers I have would sound better. I have a pair of 15" paper cone woofers from a pair of old Magnavox consoles and a pair of 1961 Jantzen hybrid electrostatics that use a very nice pair of red 11" woofers that sound really nice.

I've tried to figure out the Pi software and methods used to measure speaker attributes, but I cry uncle.

Anyone in the area who'd like to help out?
