I'm back from AXPONA (Chicago), and had a chance to listen to ML's brand new Renaissance ESL15a stats in the Audio Video Interiors room. They were powering these with a pair of McIntosh MC-1.2kw (1200 watt) monoblocks.
Each Renaissance has a 500 watt class-D power amplifier built in, powering a pair of 12" woofers (one firing forward, the other towards the wall), which they mentioned helps smooth out the bass response within the room. The stat panel is 46"x15" and if I recall, the crossover frequency is at 300Hz. From what I heard across two different demos, it is a very seamless match. The room was less than ideal (it was rather long, and they had a separate demo on the other end of the room which they would switch to at half hour intervals), but I found this to be quite a powerful sounding speaker, a lot more dynamic than what I expected. The demo from the first row was OK, but when I revisited and sat two rows back, the imaging and soundstage locked in tightly.
This is the flagship of a new series of stats, so I'm hoping a model will come along that is far less than the $25k price tag of this pair. I certainly wouldn't turn them down if given to me.
But they were one of the highlights of the show for me.
The only other speaker which drew me in was a pair of ProAc Response D48B, driven by some nice VTL tube electronics down on the lower level. They use a ribbon tweeter and a pair of 6-1/2" woofers--the bass from this was incredible, and the sound, again, was seamless. The rep in the room mentioned he liked these since his reference speakers are Quad electrostatics, and these came closest to the electrostatic sound of any "box" speaker he'd ever heard.
And I have to say that for the money, the demo of the ELAC UB5 bookshelf speaker was mightily impressive--it is in the upcoming Uni-Fi series. The entertaining Andrew Jones was on hand to describe the philosophy behind the speakers. For having a single 5-1/2" woofer, they filled the room with surprising amounts of bass (enough to blow around the curtains behind them!), and at $499/pair, I would have no issues recommending them to friends who have more modest system needs. There is also a matching tower speaker in the line with three woofers vs. one ($499 each), and a center channel.
Saw plenty of other things, and the marketplace kind of reached its hand into my wallet a few times...quite a good time!
