1974 Mach3 (Pacific Stereo) Speaker Refurbishment

Replaced drivers and crossovers in these Mach3 speakers, purchased new from Pacific Stereo in 1974. The woofer surround on one of the speakers was badly decayed. I was surprised to find that one of the woofers had been replaced in 1975.
New drivers and crossovers came from Parts Express. Parts list is at the end of the video.
They sound great again!
