Soundlab speakers...how reliable?


Contemplating buying SoundLab M-2PX or A-3PX speakers to be driven by some Atma-Sphere amps, how reliable is the speaker? What concerns or issues have you had?

In January Soundlab introduced a new backpanel which not only made the speaker a lot easier to drive but also has it sounding better, regardless of the amplifier used.
I've owned Soundlabs for over 10 years in midwestern humidity with no problems. I recently upgraded to PX panels, the new (consummate) backplates, with the hot rod upgrade. If they were problematic, I would never have stayed with the brand.
If you're buying used, & are concerned with membrane reliability, it should be noted that new membranes can be factory applied to the panels at a fairly reasonable cost.
Rather than the M2's or M3's, I would recommend considering the full-size M1's. My room is approx. 13.5 wide with a 7.3 high ceiling & the M1's & M1PX's have worked quite nicely.
A thread was started on the Soundlab Owners forum to correlate with this one. Concurrent and additioinal information can be found at: http://www.soundlabowners.com/cgi-bin/yabb2/YaBB.pl?num=1378173964/0#3.
I have owned SoundLabs since the 80's. Although panels made from the 80's until late 90's were fragile and could be damaged by excessive power or humidity corroding the points where the connections were made to the Mylar, the two cases of problems with panels I know about during the last ten years were due to mishandling during shipping or moving the speakers.
Since I own PX panels I became more confident, and I have played them a few times at much louder levels than before, fortunately without any problem and sounding great.
