JKent Posted September 17, 2012 Report Share Posted September 17, 2012 Often called "hot cross buns" (do a google search on that and woofer). KLH used the technique on a number of their woofers. I believe it was to add mass (and/or stiffness).Kent Link to comment Share on other sites More sharing options...
