Setting up a home theater, not sure about speaker placement and other things

[vovin]

I've been cursed with the room from hell. Although it is a decent size, there are so many obstacles on every wall that the only place I can fit my TV/speakers is into the corner firing down the short end of the room. I know it's best to stay away from corners as much as possible, so I've tried to shift the speakers as much as I can away from that wall, but I run up into the fireplace. If I go any further, the TV is going to be partially on the fireplace. Also, the rear of the speakers are pretty close to the wall, but i'm only sitting 11 feet away from the speakers so I don't think moving them closer to my seating position will do much good.

Speakers: Monitor Audio Bronze 2
Subwoofer: Mackie MR10S Mk3
Surround: 2 average Polk speakers

As you can see the subwoofer is on the left side of the fireplace. It's pretty far from the speakers and I don't know if that's a bad thing, but the only other place I can think of putting the sub is in a corner and I find the sub frequencies get too boomy there.

My receiver default sets the crossover on the front speakers to 80hz but i'm thinking I should go higher. My Bronze 2's aren't that big and I'm thinking of setting it at 90-100hz.

I'm sort of all over the place in this post because I don't know where I should be making improvements or what options I have. I did think about building some wall panels for sound absorption in these spots:

I'd love to hear your feedback.

That is a tough room from the pics what with doorways and fireplace, altho wondering what that wall off to the left of the fireplace/right of the couch is looking like. I'd pull the couch away from the wall, having your head right up against a boundary won't help.

Hard to know where in the room your sub works best (let alone where there's an available spot) without some experimentation/measurement (or sub crawl), but where you have it may be fine. Experiment with the higher crossovers, nothing inherently wrong with raising it as long as your sub has the frequency response to handle it (keep in mind a crossover isn't a brick wall). You may have localization problems with a single sub at higher crossover, tho.

Having your speakers against the wall isn't about the distance to your seat alone, the interaction with that boundary behind/to the side of the speakers is in play, try pulling them out into the room some. The speakers are quite close together, generally you want your L/R speakers to form an equilateral triangle with your seating position.

Try some reading of articles here on speaker and sub placement for further ideas/thoughts

There's a garage door in the left corner plus the staircase, so it's really only 2/3rds of a wall.

LOL well that's no help

What about mounting the tv above the fireplace? Not sure if it's even a good idea, but I've seen people do it. Looks like if you could, it would give better speaker placement.

I have about 5 different devices and a ton of wires I wouldn't know how to hide if I were somehow able to mount the TV above the fireplace. And then the placement of the couch becomes an issue because of the door. This is a shot directly from the fireplace.

If it helps, I can bass trap the corner where the right speaker is placed now in the first image. At the moment i'm thinking of keeping the placement as it is and trying to improve the sound with acoustic panels.

3-inch panels built for the back wall.

I still have a whole bunch of insulation left over but not sure what to do with it. There's one corner to the right of the front speakers I could bass trap, or build a cloud for the ceiling.

How about placing the tv against this wall at the center of the room width with speakers on ends. Is there a place for left speaker?
