Quad 21L vs. 22L2 Sonic differences?

Never heard the 22L2 but I have owned the 21L2 as well as the 12L2. I preferred the 12L2s.
Although I'm sure it had to do with room placement. The 21L2 is very short and IMO needs to be raised up on some sort of small stand to sound right. As the 22L2 is taller, this probably would not be the case. Good luck with the search.

Hello,
I have a pair of 22L2 speakers finished in Rosewood. Got them used here on Agon from a seller - Lanemart - who sells numerous QUAD speakers. I power them via Monarchy Audio SE-100 Delux amps and a VTL 2.5 tube preamp. Very happy with the combo but to be honest never compared them to anything else except for the older Mirage speakers they replaced. Very detailed and the bass is good but I also suppliment the bottom octave < 50 hrtz using a FR15 Velodynne Sub. The only complaint I have is that the spikes do not thread properly into the base inserts. The tolerance between the spike threads and the threaded inserts is not correct. I fabbed up some different spikes. Other than that I'm happy with them. Best wishes.

I have always been interested in these speakers but have been unable to hear them in person . Have read on several reviews that the 22L is rather bright and can therefore be fatiguing during extended listening.Have others found this to be true??

Rrm - in my listening tests I never found the 22L2's to be bright. Music was Monolake (electronic), Heartless Bastards (garage rock), Black Keys, Dire Straits and of course Bowie. Some Bowie tracks tend to ring on my home systems, but they both feature metal dome tweeters, the 22L2's have soft dome tweeters - this could have caused some slight reduction in harshness.
One of the testing rooms was at a dealer here in Denver. He had systems on three walls, and shelving on the fourth, but the 22L2's got the best electronics (high end Vincent and Parasound Halo seperates) and some acoustical foam treatment behind the gear and the listener. The other testing room was in a hotel at RMAF, the 22L2's were on a side wall in an alternate system. They still sounded great. They didn't come close to the electrostats on the other wall, tho!
Yeah I've read that 'tech radar' review myself, and I cannot understand how they can give the B&W 683 a 5 star rating, and give the quads only 4. That is NOT the case. And I am not saying that because I'm a B&W hater, My HT system is B&W 6 series and I love it. The Quads are just better. The only speakers that would beat them might be the Focal 836V, but I haven't auditioned those yet. KEF's new Q line is also on my list...
Lots of dealers run speakers costing less than $2000 with home theater receivers. This is NOT the best way to audition speakers for a 2-channel music system. I was lucky to hear the Quads on some really nice 2-channel gear.
Regarding bright speakers - this is why I bought a pre-amp with tone controls - if it gets harsh I tone it back a little. I'm not a purist. I'm into the music!

I owned a pair of 22L2's for about a year or so. Had them paired with a few different amps, first a musical fidelity a308i integrated, then a sunfire multi-channel, then a musical fidelity A5 and then finally a Rogue Audio Stereo 90 tube amp. General concensus through the whole trial run was they're detailed and can be a bit bright/unforgiving with a resolving digital front end. I wouldn't categorize their response as flat. They have a mid band dip from what I've read online, which may/may not have contributed to the brightness/lack of midrange.

That said, they're a sub $1k (used) pair of speakers so you get what you get. They have a great finish to them and are honestly very nice for what they are. I upgraded to a pair of speakers costing 4x the price, so a comparison between the two isn't fair. With the right gear/setup and to the right individual, I could see where the 22L2's could be fantastic.
