I did a bi-wire on my Ascent i's and couldn't hear any difference. I then passive bi-amped with an old Carver M1.5t to the panels and did hear a difference. Wire is #12 for a run of about 30' to both upper and lower sections

I'm passive bi-amping my Ascent i's with Yamaha 120W receiver amps driving the bass connectors and Carver M1.5t driving the panel connectors. YPAO sorts out the levels. I hear a better sound in my HT, which I describe as "more clarity". Since I am not an audiophile reviewer, I'm not going to...

Used Carvers I'm using the old Carver M-400t for the center "Theater", and the Carver M 1.5t for the panels on my front Ascent i's. The "t" stands for "tube transfer function" Bob Carver's claim (verified by some reviewers) to give a tube amp response to a solid state amp. They are high...

Spend on the center I have the M-L Theater center--the best they made at the time and I've never looked back. No more "what did he say" from my wife. But, I have an absorber behind the center to reduce the effect of any backwave reflection from the rear of the stat panels. The center is...

I agree I have an 11.2 HT system with M-L Ascent i for mains and Theater for center. All the other speakers are cone-type. I also have absorber on the walls behind the M-L speakers to absorb the back wave. I like the stats for their clarity, fast response, and the directionality which...

There we have it. For those of us wanting to attenuate the back wave, the Minitrap HF behind the speaker is best. My WAF work-around of putting the foam in the speaker cavity absorbs the back wave, but introduces comb filtering because of near field reflections. Not good. For my...

Jonfo--excellent! Actual A/B measurements are what is needed. My seat of the pants may satisfy my ear, but it should not be a substitute for objective measurements. Your effort may be just what is needed for this methodology to be useful and I look forward to the results. My ear could be...

I have removed two of the layers, which is quite easy to do, and this picture shows the result. It looks much neater, and the foam is bowed away from the panel. I can now hear a much reduced backwave sound when I put my ear close to the foam at the back of the speaker, where I could hear...

Rich--I appreciate your informed opinion. The manufacturer of the foam claims an absorption which appears to me to be equal to that of the minitrap HF down to 280 Hz, the crossover frequency of the 'stat panel. As I get time, I think I'll remove two of the layers, bow the foam layer to the...

Photo is attached of the top of the Ascent, with three thicknesses of RPG foam behind panel. So, as I thought, it is not a new idea, but it is a more recent way to use a currently available generic material. I will not comment on the diffusion/absorption/bi-pole arguments. Others have covered...

Through this forum, I have become a believer in absorbing the back wave of the electrostatic panels of my M_L speakers. It became particularly evident as I repeatedly ran the YPAO compensator from my Yamaha RX-Z11 and had to move the fronts way out into the room to avoid getting the "phase...

Several years ago, I bought my Ascent i's from Tweeter on a similar kind of arrangement. They were ordered from M-L, delivered, and I had no difficulty registering the serial no's with M-L for the 5-yr extended warranty.

"Third" on the Mirage Omnisats I have an 11.2 setup, with bi-amped M-L Ascent i's on fronts and M-L Theater for center. The side surrounds are a pair of Omnisats on each side mounted one foot below the 9 ft ceiling, firing up to the ceiling. The reason for the pair on each side is that they...

Difference between Ascent and Ascent i's? I don't have a schematic of my Ascents, so let me see if I understand this correctly. My Ascents have separate connectors on the back for the upper panels and the lower cone speaker, and a jumper to bridge the two. If I bi-amp the two, the crossover...

Results Have completed the prime test. Carver powering the stat panels, and internal Z-11 the cone speaker of the Ascents. YPAO correctly set the levels. Not much listening time, but there is tremendous headroom on the panels. I would say that this was a successful operation

That's two for the simple solution of using the Carver for both sections of the Ascents. Since I already have the speakers bi-wired, bi-amping is relatively easy. The time consuming part is running the YPAO in each setup. I'm expecting a second sub, soon; and I'll try all the configurations...

Thanks. Your suggestions make sense. Any others with opinions on this?

I've just finished a dedicated home theater using the new Yamaha RX-Z11 in an 11.2 system. My fronts are the bi-ampable M-L Ascents and an M-L Theater as center. The RX-Z11 specs out at 140w/channel into 4 ohms, and allows bi-amping the fronts, but you lose the rear channel amps if you do so...
