Sorry, I'm not sure I understand the "sad story" reference to Selah Audio--can someone explain?
Jim and Dennis, have you tried modifying this design into a 3 way, utilizing the Satori MD60 two inch dome midrange? I've heard wonderful things about these Purifi woofers, but no seven inch bass driver excels at reproducing frequencies above 1 KHz. Seems like adding a dedicated, lightweight driver for the 1 to 4 KHz frequencies would take these speakers to state-of-the-art performance levels.
