Audyssey and room acoustics

post #1 of 10
Thread Starter 
Edit: I didn't even get this where i meant to put it, "The **OFFICIAL** Denon AVR-XX13 Model Owner's Thread", sorry. I don't see how to move it or delete it. Perhaps a moderator can help me out...?

This thread may be better put in the speaker forum, we'll see, but my questions are about how the Denon and Audyssey will handle my room acoustics. If any ole receiver will handle this (or not) in the same way then I would be happy to move on over there.... I have pretty much decided on getting a 2313CI and (probably, though still researching) one of the HSU Research 5.1 surround packages, ie., Hybrid 2 (http://www.hsuresearch.com/products/hybrid2pkg.html). I have room behind and could do 7.1 but I don't think I need/want that at least at this point. I may use Zone 2 for some outdoor speakers.

The room I am going to use this set up in is not an ideal theater arrangement (understatement, I know). It is 21X30 but the watching/listening area is in one end/corner. There is a drop ceiling that is just a bit below 8ft., carpeting on the floor. The windows that line the two walls are up about 54" above the floor and are deep (12" or more) window boxes, each window is about 45" long and 2' high. If you can't guess, this is a basement area that is partially above ground and the sliding doors on the end are walk-outs. Attached is a rough (not to scale) drawing.

My first hurdle will be how the heck I am going to place and wire the surround speakers. The front will be no problem, the rear, I suspect will have to be on stands and wiring may have to run over the carpet (which I loath). I will also have the same problem for the sub as it will likely want to go in the back of the sofa or other equally hard to reach spot and to which I will need to get power. Oh, and not shown on this is that the whole wall behind the sofa is a long countertop with lower cabinets with doors, so nothing can sit in front of that.

The second problem assuming I can even solve the first one, is what is this going to sound like? Can the Denon and Audyssey adjust the acoustics enough that will make it even worth doing this? I am worried about the deep entries at each slider (the ceiling drops down there making little foyers at each door), the window boxes, and the large room all ganging up to make this a waste of time and money. Should I just get a crappy HTIB setup and call it day?

Thanks,
Tom

Wall mounts hanging from the ceiling perhaps?

butter and jelly please.

No on the HTIB.
Audyssey will help "some", but I don't think it can cure this. Others with more experience may be able to help more. I think you will want to reduce reflections off of that end wall. Absorbers or even heavy drapes.
You have one of the only rooms where I am tempted to suggest in-ceiling speakers for surround. I really don't like them, but if you place them a few feet behind and off to each side of your seating area, it COULD just work about as well as any other option. I would not bother going beyond 5.1. I would put the sub up front. My choice would be to get 3 matching speakers across the front and if possible in-ceiling with the same driver family. YMMV.

Here's a recent convert to Audyssey using an Onkyo 605 with the lowest version of Audyssey 2EQ ...

I have a projector screen so my center channel is on the ground. My subwoofer is behind my sofa. The left speakers are about a foot from the side wall while the right speakers (5.1) are 10 feet away from the dining room wall.
Would it be a waste of money to buy a 1612 for the purpose of using the auto room eq feature? Currently i have an Onkyo tx-sr605 (don't have the mic for the auto eq) with def tech speakers, including Powermonitor 700's that have built in powered subs, which i would imagine would complicate things.

The surround field seemed more pronounced. I actually did a blind test and could tell whether or not Audyssey was on. So if I'm getting decent results already with 2EQ, I would imagine that the Audyssey MultiEQ XT should be really good. I'm leaning towards getting the 1712 from Accessories4less.
On a side note, has anyone used the virtual surround sound with headphones?


1. You may want to just start out with a 3.1 setup to begin with and worry about how to do the surrounds later (perhaps wireless?).
2. Odd setups is exactly why using an AUTO EQ is necessary to improve the surround fidelity.

Audyssey will help.

Don't go HTIB unless you are really short on funds and must have surround of some sort.

Pull up the carpet and run the wires under it, poke holes in the carpet right under the speaker stand or mount them on the ceiling if possible, it's really easy to run wires through a drop ceiling.

The biggest positive I read in your rooms configuration is that you have carpeting.
Are you having any shades/curtains/blinds installed on all those windows? Sorry if you addressed this, but I didn't see it if you did.
Here's the deal. If you are not going to put up some kind of window treatments, not only will your sound suffer, but your video will as well due to all the ambient light entering your room and in the end, you will be just wasting your time and MONEY.
You MUST address the window treatments or nothing will help you.

This is also in your favor. Where you want your absorptive material is at ear level and below when sitting. So by adding some sound panels at your first reflection points, (54" and below) this would help immensely.

Placing the sofa in the middle of the room is also likely to result in a bass null so you'll want to either move it forward 2' (ideal, as optimum distance for a 60" HDTV is only about 8') or back 2'.

Wow, thanks for all the comments! I am somewhat encouraged that it isn't completely hopeless. More questions...

I thought about putting the rear surrounds in the drop ceiling, that would be easy from a installation standpoint, but I wondered if that would vibrate and sound like crap? I have used in-wall speakers and had them sound quite nice, but never in a drop ceiling. Does anyone have direct experience using speakers that way? Hsu makes an in-wall that I could mount up there... Also, I didn't think about bringing the mounts for surrounds down from the ceiling. Might look a little odd hanging there in space, but it might work..? Also, would it work to have three fronts in normal positions (on stands or whatever) and have the two rear surrounds up higher in ceiling, or should the fronts be higher if the rear ones are?

I hadn't thought about window (or sliding door) treatments as we have land around the house so I don't worry about what's outside at night much wink.gif but will look into that. The windows are up high enough and the ones to the rear of the seating area are under a deck outside that light reflections haven't been a problem. Also, the sliding door is set back in the little foyer I described that light from it too hasn't been an issue. While there is a lot of glass it is surprisingly subdued light. I think treatments would certainly improve the sound reflections though and even more light suppression isn't a bad thing.

I am flexible with the furniture so moving it forward is easy enough to do.

Many thanks again,
Tom

Tom, I have no experience with speakers in a dropped ceiling. Never worked with them. I think this would be a question you would pose to the speaker manufacturer. You mentioned you were interested in HSU speakers. I have no experience with them, but I would call them and ask your questions about the model you are interested in.
What about the idea of making faux columns for your back speakers directly behind your chairs? Then you could always shelf mount some speakers on that back wall for 7.1. Just a thought. Obviously this is not the best configuration with the speakers at such a distance along that back wall. But your situation is not the greatest anyway.
Light suppression isn’t the only thing I was considering window treatments for. With the right blinds and curtains, you could tone down some of the sound reflections coming off all that glass.
Then if you added the accoustic treatments under the windows, it would help quite a bit.
