JBL 4411 - what is your take on these?

So this is the 'studio monitor' version of the L-112. The L-112 was the last of the L-100 upgrades, better than the L-100 and a little better than the L-166 Horizon. I can remember hearing them on occasion at the Tower Records on lower broadway. Not a good place to decide if they are any good or not... This model JBL is probably less hashy-harsh and a little warmer presentation if I remember. Not high end but not bad, can fill a big room easy. The better amp you use, the better the bass and sound. Upgrade the caps, wire and jacks and you're in business.

"Liquid" to get back to you, I did some improvements to my JBL L-166 Horizons but honestly it did not change the sound that much. I put in cardas speaker jacks, much thicker internal wiring, and added some dampening materials here and there inside. If I were to do it over, I would perhaps change out the capacitators in the crossover, however, the original capacitators used by JBL are fairly high quality and perhaps don't need to be messed with. For classical and female vocals I would head in a different direction... smaller british minimonitor Harbeth Spendor you get the idea.
