I may be interested in trying a new crossover that's available for my 34 year old pair of JBL L88+12s (L100 equivalents) that I saw here:

http://www.troelsgravesen.dk/JBL_L100.htm
Described thus:
"JBL L100 Century Up-grade Kit
from Jantzen Audio
The kit is suitable for those JBL variants using the 123A woofer,
LE5-2 midrange driver and LE25 tweeter, e.g. 4311".


This site seems to be from late 2006 to early 2007, from Jantzen Audio (Denmark). Has anyone tried this kit???
And if so, what are your impressions & thoughts about it?
(Hmmm, I wonder if these L88+12s could be set up for bi-amplification at the same time?).
