John,
I sold my pair of AR-5 this afternoon. First the original Sprague capacitors in the crossovers are superior to Dayton. If they scope out I them alone. The AR-5 is a good sounding system with 8 ohm versions of AR-3a mid and tweeter domes. I have a pair of LST-2 with the same drivers, only three times the mids, tweeters, so the 5s weren’t really needed.
