Wayne-Thanks very much for the Pi 7 plans. I came across (and purchased) a a set of drivers from a late 60s Curtis Mathis stereo console unit. The woofers are a stamped basket 12" with paper cone and cloth surround, no markings other than "29B49-1" which I presume is the model number. The tweeters are a 2x6 metal horn tweeter, no markings other than "V/60". The crossover consists only of a single capacitor (4.7 uf 25VDC), no coil or anything else. The drivers are in pristine condition and I would really like to incorporate them into a Pi 6 (Theater) design. Can you offer any suggestions on determining the specs on these speakers ? Also- please email the plans for the Pi 6.
Thanks !
