Resident speaker guru Chris Brunhaver is back with a wide ranging discussion (no surprise there) with the guys about what's going on currently in the world of speaker design.Multiple pole gaps,  magnetic speaker parts, woven poly cones and hysteresis.... sounds about right for a visit from  Chris.Also in this episode, listener questions about woofer movement when playing back records and about how to set up a listening environment with no sweet spot are answered.Be sure to listen to the end, where the guys suggest a new acoustic album full of young virtuoso players. This one's a classic marriage of excellent recording and exceptional music.
