The most placement forgiving planar speaker?


I am considering going to a flat or planar speaker. Maggies, Martin Logan, I.S., Quad...

I have been told most are very touchy as for room placement. Which of these are more forgiving and cast a wider sweet spot?

Or...Is this a silly idea to begin with (all be very touchy) and I should go with a large speaker with a ribbon element like a vmps.

Thanks,

Ken

Dont forget all the complaints about Martin Logans bass response with the panal...there are lots of threads that talk about this fault in Logan's
Drken, Re not wanting to put the speakers more than 2 ft from the rear wall....Don't know about the Soundlabs set up - I'd take Albert's and Duke's word on that issue.

However on other panels, or electrostats, 2 feet from a back wall may not be where they will sound best. To get them to do so you are likely to have to treat that back wall in some fashion to deal with the back wave from the speaker, even then it won't sound as good as pulled out further into the room.

But, that said, putting a full range speaker 2 feet from a back wall may not give you the smoothest bass response either, but at least you won't have to worry as much about the mids and highs except from sidewall reflections which are not as much a problem for most panels and electrostats).

I love Stats and panels, but I think its only fair to say that to get their best you have to make a real committment to set up. (Wish some one had told me that before I got the Quads, which was before the internet audio sites appeared). Good luch with whatever you choose.
Hi Fatparrot,

I thought I did explain the venetian-blind effect, albeit succintly: "I am talking about the noticeable discontinuity or abrupt shift in the image as you move you head from side to side."

Let me try again. With cone/box speakers, as you move your head laterally, say slowly from left to right, the center image such as a singing voice will remain in the center for a while, say for six to twelve inches; when your head has moved far enough to the right, the voice will shift to the closest (right) speaker.

With most dipolar speakers, i.e. planar speakers producing sound to the front and to the rear of their diaphrams, if you move your head just a few inches from left to right, the center image will suddendenly disappear and then reappear slightly to the right. This effect will continue as you keep moving your head. Now you hear the center image, now you don't, and now you hear it again, similar to the way you see only between the slats of a venetian blind: thus the "venetian blind effect." So to get a stable image, you must keep your head stationay, locked within a few inches of the listening center.

This sounds far worse than it really is. And the Maggies aren't certainly the only speakers to do that. All dipolar/planar speakers do, some more than others. In other words, they all have a relatively small sweet spot compared to cone/box speakers. This sweep spot gets bigger with each new generation of the Maggies and is quite large with the Soundlabs.

The venetian blind effect can be quite disconcerting to some people. When you are within the sweet spot, however, the sound is vividly three-dimensional and truly magical. That's why I continue to have a love-hate relationship with dipolar speakers.
Dont get Innersound speakers if you are worried about a sweet spot, its about 12 inches....your head will be in a vice
Take a look at my system; Bruce Thigpen, the designer of the speakers said, "No problem" with them being inches from the wall. He was right. You'll want to do some room tuning, though, behind the planars. Makes a big difference in ridding unwanted room reflections.
