Two questions about the latest Martin Logan's

Thanks everyone! I figured the size differance was driven more by market than technology. The trend for many OEMs is smaller speakers that integrate better with home decor. This is fine as long as sound or build quality isn't affected.

I think my shock at the smaller size of the Vista speakers derives from my experience as an engineer: There appears to be less for the money. I don't think this is actually the case. Martin Logan has always manufactured excellant, high-quality products.

The generation of ML hybrids starting with Summit/Vantage show significant improvements over their previous efforts IMHO. There is better bass integration, less need for high power amplification due to the built in woofer amps, and in general a more vivid, true to life sound. The bass level controls are a big help too for getting the right balance, especially in smaller rooms. Paired with the right amplification (McIntosh tubes are a terrific match!), they provide a level of musical enjoyment that is not easily beaten in their respective price ranges. While it is true that the current Quad electrostatics are perhaps a bit more pristine, detailed and better integrated in the bass (no cone woofer), these ML hybrids do dynamics and deep bass better, plus have a wider listening window. These are acceptable trade offs for me. Overall, a very fine speaker!

I have auditioned the Summits a couple of times at my dealer.

The Summits panels are alot bigger than the Vantages.

I liked the sound of the Summits driven by Mac 501s.

I did not listen to the Vantages because they where not ideally set up in a different room.

One thing I dislike about the Summits is the image height. It sounds like it is about 18 inch off the floor. This is because the woofer is about 6 inches from the floor and is crossed over at about 250 hz or higher. I brought this up to the salesman and he said the reason is their set up guy is really short. Which is B.S. He also said they just need to be tilted back to bring up the height.

Panel speakers sound best when they are straight up and down. I imagine that you could put them on some platforms to raise their height but these speakers also have downfiring woofers. So the platforms would have to be very solid.

I would assume that the Vantages would have the same problem because they are a very similar design.

YMMV,
