Hey Todd,
I can understand your attraction to these older approaches .
I'd suggest ( before it's too late ) that you try integrating some Altec 288-8K drivers into your system .
Every observation you make about the le85 applies to the Altec 288 ( but in spades ) .
Replacement diaphragms ( at only $100.00 new from GPA ) makes the investment ( mostly ) a no-brainer ( centering the 288 diaphragm can be a challenge ) .
Most new users of any Altec 288 ( coming from the JBL world ) will want to bring along their favourite tweeter ( because the 288 has such a calm, tenor-like, natural-quality to it's voice ).
cheers <> Earl
