Here are some links to comments about the TRW-17 Rotary Woofer on the net.  Many of these are from those who listened to the woofer in operation at Rocky Mountain Audio Fest (October 2005), the Bay Area Audio Society demonstration (May 2006), T.H.E. Show Denver (September 2006) and CES (January 2007).
