Hello: I am a great fan of vintage audio gear, and am fortunate to own a Paragon. It produces mesmerizing midrange but is distinctly bass-shy. My electronics include a McIntosh MCD-1100 CD player, Mac C-46 preamp, and a pair of Mac MC-30 power amps, with new or strong vintage tubes. I am planning to clean all connections with CRC QD contact cleaner. I welcome comments from people who have first-hand experience with Paragons. Is the 150-4C weak, even though it is a 15 inch speaker coupled to a folded horn? Any other suggestions to improve the bass? Thanks in advance. Roger
