I’m in the process of restoring three pairs of L166s (4 x refoaming, replacing one or two LE5s & one 066, wood work, audiophile capacitors & wires etc.). Nice winter project. :)
During my search for the 066, I’ve found that 077s are easier to get hold on – probably because they are repairable (not cheap though).
This started me wondering:
How about building a pair of “JBL L177” which would be the natural model number of a L166 with the use of 077 HF-unit:
· Same woofer (122A)
· Same midrange (LE5-8 – maybe changed to LE5-2 or 2105)
· 077 for high frequency
· X-over???
Could the original N166 be reused/modified (cuts to tweeter at 6 kHz – in L65 Jubal 077 is used from 6˝ kHz). Probably a sensitivity issue as well?
· New enclosures build close to the specs for L166 (to fit the woofer), but
o “mirrored” (for better stereo perspective)
o the midrange in level with the front (less reflections)
o new front grills (better transparency)
o stand integrated/woofer raised to app. 20"
I very much like the sound of the L166s that are working. They are on 18” stands, deliver enough and tight bass for the room (15 x 15 feet) – and are close to max WAF…
Comments/opinions/suggestions to this (crazy?) idea are welcome – especially on the X-over question.

(PS: I'll leave the old enclosures as they are so I can go back to the original set up).
