[Vintage-Audio] Re Speaker Performance

Thu Aug 15 23:40:01 2002

When I picked up my L-166s he had a mint pair of L-100s and
they had too many highs even with the both knobs turned
down. The 166s are better, with a dome tweeter but they
still have more highs than I like. I am slowly getting used
to them though...the bass is superb and I am losing all my
HF hearing anyway (-6 at 12KHz)
