Planar close to a rear wall? Quad for example?


In my room I have about 1 foot clearance for a speaker from the rear wall. Can this be done with one of the new Quads or is this just a pipe dream?

Having played with a pair of Quad 989’s for over a year now, I would have to say you will be losing a lot of what makes a Quad, a Quad.

In my room, which is 23x21, with a sloping ceiling going from 9 feet to 16 feet and one side of the room open 16 feet ( from a foyer ), I have had to place the 989’s 5 – 6 feet off the back wall, and 5 feet off the side walls. Placing them so close to the wall will waste your money. This would hold true for any dipole speaker as well. There are plenty of good speakers out there that might be OK up against a wall. As a general rule of thumb, almost any speaker sounds better if kept off the back and side walls. Results and effect will vary with each brand and model of speaker.

You may very well find a different brand or type of speaker that will sound better that the Quads in your set up, even though they might not sound as good as the Quads if both were set up in open spaces.

Remember, a great top dog speaker sounds great because it is set up correctly, and yes there is a correct and incorrect way to set up and speaker. A great speaker that is set up incorrectly, may sound worse, that a lesser speaker that is set up as intended. Example. In my room I really wanted to place the Quads on the long wall. That wall has a wonderful view to the outside, with two large ( 7 foot x 7 foot ) casement windows, and a fireplace in the middle of the wall ( total of 23 feet ), the opposite wall is open 16 feet. Tried as I wanted, and the Quads just sounded to bright and brittle when placed this way. By the way this position was the best for furniture setups as well. We are now looking for custom drapes that we can use on those two windows. My thought is that I might be able to get away with placing the speakers in the position I want, and use the drapes as a sound control item. Open for casual listening, and close for serious listing. This would probably limit the serious listing to the dark hours, since closing the drapes during the day makes the room way to dark.

Recently I walked into one of the national audio chain stores, but not a big box store. I noticed they had a room with a small pair of Martin Logan’s and a Krell amp. I asked if I could hear the set up. I had a few CDs with me that I knew well. The set up was awful. Based on that set up ( close to the wall, and only six feet apart ), I would never, ever, considered buying those speakers. A few weeks later I was in another store ( in the same town ), who come to find out, had the whole Martin Logan line up. I sort of joked with the manger how I had already heard the small ML’s in another store. He laughed. He said that I had not heard them set up correctly. I was game, and had the same selections of CD’s with me. Boy was I blow away. It was a night a day change. Based on hearing them correctly set up, I recommended them to a friend. I them when into their big home theater room and listened to the ML Summit’s, and again was floored. Based on being able to hear the speakers set up correctly, I am thinking about maybe buying the Summits and selling the Quads, ( yes I miss the visceral bass about 50 % of the time )

Give us an idea of your room size and why only one foot off the wall ??
It will just not work. Not a foot away from the wall.
A waist of great speaker. IMO
hi mjstark:

it is too bad you were not with me when i heard a pair of quads set up in a kitchen. i di not think it would work either. i played an orchestral selection--ravel's alborado del graciso conducted by ansermet.

although depth was not ideal, the timbre of the instruments was quite impressive.
If its not common knowledge than it should be: all planar speakers need to be a minimum of 5 feet from the rear wall!

Any closer results in tonal colorations, the most pronounced being in the bass. Oddly, the only speaker I have seen that worked at all well at distances closer was indeed the '57, but invariably the owner was using a transistor amplifier, which cannot play bass on the speaker. Nevermind- the backwave reinforcement 'sort of' takes care of that. But put a good tube amp on a setup like that and the owner complains of too much one-note bass.
