Who uses ADS Speakers

From 1974 into the 2000’s I worked for Tweeter, which was Boston’s main a/d/s/ dealer. Took dealer training and factory tours with Dr. Goderhard Guenther, Mike Kelly, Dave Marshall. I owned many models, but not the really big ones like the L2030 series. My faves were the 8”/1” 2 way in its many iterations from the Braun L500 to the L570II. They killed the goose when the tacky soft dome was replaced by the polymer dome, IMO. I also loved the Gen 2 3-ways that used the .75” tweeter. The L730 was a great one.  I never felt their bass response had what the Large Advent had in terms of low end sock but Dr. G said they were simply better damped than Advents and were more accurate. 
I have a pair of L300e in my kitchen running off Zone 2 of my AV receiver and they play more hours music than my other systems combined. 

In the late ’70s I had a pair of ads monitors. A friend accurately described them as screaming bricks.

Had L710s for a few years (late 70's I think).  Moved on from there to satellite/subs.

I have a pair of L880's for my bedroom system. I think they sound excellent with a smooth, well balanced sound.

I owned an ADS PB-1500 back in the day. It made a great coffee table, but a lousy sub.
