I have a number of JBLs in 2 major systems, plus an L19 system in the exercise room.
Downstairs in in the TV room, a 7.1 surround system : L20T smaller 2 ways with Titanium dome tweeters (used for rear surrounds); L100T with the crossovers upgraded to the smoother L100T3 design ... (use them for side surrounds); plus a pair of 4341 4-way studio monitors in bi-amped config for mains in stereo mode, or as fronts in surround mode for multichannel audio/movies/TV.
Upstairs with a cathedral ceiling: a pair of L-200 speakers I've rebuilt into L300-caliber speakers (added slot tweeter, custom crossover and walnut mid-horn w/2441 driver);
Plus a pair of Magnepan MG-IIBs ... and just got a pair of perfectly working DQ-10s ...
The DQ-10s are quite interesting - much different than the big JBL 3 and 4 ways.
I like them all for different reasons. The Dahlquist is great for putting music on and listening or walking around the house and just having the rooms fill with music - frankly, they are the best sound speakers to listen to from another room - and not bad for a lot of music in that room.
The big JBLs with walnut horns can be a bit fussy - a bad recording (some of those fast-cheap 70s album conversions to CD) can be almost unlistenable.
But other music is quite nice, and there is nothing like some nice jazz playing on them while reading the sunday paper ...
At some point I will need to get rid of some of these speakers - hopefully, not today.
In my mind the older Magnapans go first ... but which of the 2 big pairs go next will be a hard choice ...
