As for the L-220, IMO never was so lousy sounding a speaker so well made, a major distortion and compression generator; the LE-14 woofer was overtaxed for the intended use and the voicing was boom and sizzle. I was given 4 of the things, gave 2 away and parted out the others, a guy in Norway was keen for the 15" passive radiators. The boxes I sealed and used with Bozak coaxials as surround speakers. The cats eye tweeter is good, way better than the bullet but not better than the slot as my memory serves me; it was a long time ago.
