I tried the MMG-Ws (5 ohms, 88 db sensitivity) with a Panasonic SA-XR10 without much luck. While the Panny sounded great with 8 ohm speakers, the Maggies never came to life with it. I've read in the archives that several people have had success with JVC driving a pair of even larger Maggies. Would the JVC be able to handle four MMG-Ws crossed over at 100 Hz?
