Ok, so I have a relatively difficult setup based on keeping my marriage for surround speakers.
I REALLY wanted 7.1 and was going to move my couch out a bit to accommodate, but my wife is fighting me, so I am back to the couch against the back wall as in this pick.
Even 5.1 is a bit rough due to the lack of a wall on the "right" side.
HOWEVER, I came across the whole dipole/bipole setup...meaning it looks like I can place on the back wall or side wall (the one side wall will be small where the pole is) and still get a great sound, even perhaps better than my 7.1 dream.
I found these...and although not "matched" to my FCL, I really only need these for effects not music.
So here I go, are these worth considering? And will my room benefit from these? Or am I just chasing a dream?
Hopefully I did the right thing...If you think my room setup will not work with these speakers, please let me know so I can cancel my order.
Thanks in advance!
Rear surrounds don't have to be a perfect match to the front speakers in order to sound like they match thanks to most receivers having auto-calibration. Though I do recommend a somewhat similar tweeter materiel (even midrange driver material) where possible for the best chance at a "blend" for a mismatch speaker set from the front to the rear. Like, if the front speakers have metal-based horns or domes, then the Mirage speakers should do pretty well in matching up. If the fronts are more fabric/silk based domes, you may notice a more "metallic" timbre to the Mirage speakers vs the front. Poly-based domes will tend to be smoother, less "dry" and aren't really a good match for metal tweeters at all (which is why I had to go with something unusual to match up my DV series BIC front speakers).
In this room, having omnipolar speakers should sound just fine and there is no need for 7.1 unless your distance from the surrounding walls is much, much further. Since you are placing these so close to the listening position, there should be enough loudness. I am more concerned with the uneven shape of the room (the wide open left side) messing with your acoustics.
It might be a good idea to place reflection/acoustic absorbing panels on the wall to the far left (there are decorative models available that you can have pictures on so that it blends with the 'look' of the room).
Getting great sound in this room isn't impossible, just difficult and may require a bit of trial and error, along with constantly re-running your A/V receiver's auto calibration.
I figure the rear wall behind the couch is "optional" but putting an acoustic absorber there will also help improve the quality of the sound from the "front" speakers. I drew lines to indicate where I expect reflections to cause the most problems for your listening position. That kitchen is going to seriously be an audible echo chamber. I wouldn't normally recommend the acoustic panels, but I definitely think your room will benefit from them based on what will certainly be noticable delayed reflections from the front speakers echoing back to your listening position (which is really bad and will mix with the surround speaker's intended ambience in the original sound mix).
The far wall on the left side next to the pool table should have as many panels as possible from the bar to the end of the wall to diffuse the sound from the kitchen. Possibly some panels also on the front wall on the left near the pool table as well. It *MIGHT* be possible to diffuse that kitchen sound with a few well placed acoustic panels in the kitchen on at least two of the reflection points I outlined. Looks like the kitchen TV spot is already taken by the TV, so there are only two major reflection points left in the kitchen. The "best" place to put the panels for the left side of the room is likely going to be around the walls at the pool table section.
On the right side of the room, you only need acoustic panels on 1 wall to stop that area of the room from becoming echo chamber #2. I think when you look at my lines on your diagram the issue I'm pointing out will become clear.
The impact these panels will have on your sound will be night and day. This will be no small improvement. It will be a very big one. Bigger than even a change in speaker class/price. Let me put it this way. The increase in sound quality that properly placed acoustic panels will make in your room will be so significant, that you couldn't equal the quality increase even if you bought the best speakers at any price. THAT is how much the acoustic treatments will improve the sound.
If you don't have carpeting in this room, then you are going to have another acoustic issue to resolve. The rear wall will then need the absorbing panel and you will want to utilize a throw rug out between your couch and the front speakers to try and soften up those harsh reflections. The wall panels will help deaden the wall reflections.
For best results, this room is going to need acoustic panels. There are panels that are quite room-friendly and you can even get your wifey in on what they will look like (your own pictures and art).
Here is a site that is advertised on this very forum:http://www.acoustimac.com/index.php/...rt-panels.html
Their custom prints seem a bit pricey but they are some of the best I've seen. There are other less expensive choices on their site for the pre-fab type designs and they still have some nice looking prints.
