Dream speakers and amp for an 11x14 room?

Hi All,

I'm a first-time poster and hate to present an idiosyncratic problem, but I'm getting the impression that the devil is in the details when it comes to high-end audio, so here goes:

I've got an 11x14 living room that serves as a home theater, and currently have a great video projector that I'd like to mate with a top-notch two-channel set up (I've been persuaded to give up on the 5.1 surround idea). My dream is to have a system that's capable of everything - from running quick, delicate, joyful circles around Beethoven's middle quartets to disgorging "Led Zeppelin I" with a massive, terrifying soundstage.

I was initially hell-bent on floorstanding speakers - I've never shopped high-end audio until now, and remember the big floorstanders my father had back in the 80s, with 12-inch woofers powered by a big, late-70s solid-state Scott amp. The Gallo 3.1 were one idea, as well as the FJ (Blumenohofer) Oms. Both of those models attracted me partly because of their wide soundstage and sweet spot (the latter unfortunately lacking in a few other models that have attracted my interest, including the Devore 8s and 9s).

But while I've been impressed during a few recent auditions by the floorstanders, and hate the tiny little images thrown by most bookshelves, the more I read the more it seems that such bigger speakers may be a bad idea for the room in question - I don't have room to be placing speakers three feet away from the wall - two is even a stretch.

A couple of other key constraints: The speakers basically have to fit under the 6 1/2-foot-wide movie screen, whose bottom edge hangs 38 inches from the floor. That's because the screen pulls down alongside the left side of this "front" wall, while immediately to the right of the screen a bedroom door is cut into the wall.

It should be noted that this front wall is of a cheap, hollow construction - courtesy of an enterprising landlord who moved to convert my apartment into a two-bedroom - and I worry that will be a factor when it comes to bass. There's also another bedroom door - immediately to the right of and at a right angle to the first, so as to form a kind of 90-degree void to the right of where the right speaker would be placed.

Opposite this front wall, 14 feet away, is a double-door that opens into a kitchen that's about 10x11. Through all of this, the ceiling height is about 7 1/2 feet and the floors are hardwoods with a few oriental rugs available if necessary.

Now, as a stopgap, I've installed a cheap 5.1 surround system, with a right bookshelf and a center speaker under the movie screen, and a left bookshelf speaker sitting - yes, that's right - in the back corner of a bookshelf that's built into the left wall. This latter speaker seems to have trouble generating a lot of sound, given the few precious inches of space behind it. I've also got a powered subwoofer on the floor under the movie screen.

So given all that data, I guess the first key question is - are there bookshelf speakers, a center and a woofer that could take the places of the cheap ones and sing, despite the lack of space behind them? I really wouldn't want to place them, or any corresponding subwoofer, more than 6 inches to a foot away from the wall (or a few inches from the back corner of the bookshelf, in the case of the left side).

And the second question would be - provided I'm willing to move the easy chair that's in the left corner under the movie screen - is there a pair of floorstanders, preferably less than 36 inches high, much less 38, that could deliver what I'm looking for in terms of sound, given the fact that they'd basically need to be as close as 4 feet together, with one about two feet from the left side wall and the other with a couple of doorways off to its right and back right?

For those of you who have gotten this far and still have a clue as to what I'm getting at, I am both grateful and impressed. Please let me know what information I can provide to clarify the situation. I'm looking to pay up to $3000 or so for a used pair of speakers, probably the same for a used amp. Interested in everything from solid-state to SETs - but seems like I should concentrate on this speaker question first.

Thanks!

Coverto, one thing you might want to be aware of is that the ear/brain system reacts differently to early-arriving reflections relative to late-arriving ones. Briefly, early-arriving reflections tend to cause coloration, while late-arriving reflections tend to add richness and liveliness to the sound (assuming they're spectrally similar to the first-arrival sound). A fuzzy dividing line between "early" and "late" reflections would be at about 10 milliseconds, roughly corresponding to a path length of 10 feet.

So what I suggest is that you take a look at the radiation pattern of the speakers you're considering, and take a look at where you plan to place them. Measure the distance from the speakers to the center of the listening area, and then look for reflection paths that will give you a path length difference of ten feet or less relative to the direct sound.

The floor bounce is virtually inevitable, as is the ceiling bounce in most cases. How about the sidewalls? Some speakers will give you a stronger sidewall reflection than others. How about the wall behind the speakers? Dipole and omni owners usually try to pull their speakers a good five feet or so out from the wall; or if that's not feasible they often diffuse or absorb the backwave energy.

Different types of speakers are appropriate for different room and setup situations. In my opinion, it's a good idea to minimize early-arrival reflections within reason while preserving the energy of late-arriving reflections by not overdamping the room.

Duke - thanks very much for the input. If I understand your post correctly, you're essentially raising a question about sound bouncing off walls that would be close to the Ohms. One mitigating factor, I'm told, is that the Ohms aren't pure omnis, with front-facing tweeters and a wide-dispersion midrange cone that omits firing toward the back wall. I spoke to John Strobheen at Ohm who told me he figured between a foot and 18 inches from the wall would work fine for placement. I can tell you that the room is 11x14, opening into a kitchen at the opposite wall via double doors, and that there are doorways opening to the back-right and right of the right-hand speaker.

Too bad, your speakers look intriguing but I need a model that's less than 36 inches high!

True they are not 100% omnidirectional and have super-tweeters that fire 45 degrees forward and inward. Also true that they need some but not excessive amounts of distance from walls.

The wide range Walsh driver does emit sound 360 degrees however the output is attenuated in the wall facing directions by sound absorbing material located inside the cage to allow placement closer to walls than pure omnis.

I have the Gallo's and love them but I have found that they need to be well away from the walls for optimal imaging. Regarding bass you could place them with the side firing woofer facing inwards helping to make the sidewalls less a factor.

The thread listed below gives some ideas for more conventional front-firing, front-ported speakers as alternative to some of those already listed here. I think these would be more amenable to placement nearer the rear wall and adjacent to open passage/doorways on the side.

You could always try the Ohms and return if not satisfied.
