2 wks ago I purchased a pair of the unassuming 1992 JBL L1 monitors that sold for $750/pr in 1992. They utilize the 706-G1 6.5" mid/bass and 035T1A 1" titanium tweeter with what looks like a nicely built crossover. The cabinets have a sloped front which I presume is to time-align the tweeter w/ the woofer plus minimize standing waves inside the box. I expected harsh highs but they don't exhibit this. The bass is plentiful and a bit more than I'm used to. I didn't expect much from them but they sound better to me than the 602s I owned in the past and more enjoyable than the 4312s I've owned too. These speakers have a big 'fun factor' from their sound so that I'm building a system in a spare room around them.
Here is a poor photo showing the speakers. Disregard the receiver in the photo as it will not be the amp driving these speakers.
