[Vintage-Audio] Re Speaker Performance

[Bob]

My experience shows that the JBL L-100 are tinny and have
over done highs. I have L-166s which are better in that
regard and the L-200s are even better. I too have my JBLs
mounted at ceiling level and not pointed down but
horizontal. The bass is great, and it still has more highs
than I like but it is adjustable and I am still tweaking. 

My bass transient tester is Telarc Timewarp track 2 and my
tester for really low stuff is Cosmic Hippo by Bela Fleck.
