This is making my head spin....and putting a nasty taste in my mouth :(

[eurovw89]

I am doing new construction on my basement and setting up a room for HT:
The room is (give or take a lil) 11W x 18L x 8H
My listen center is 8' from the front (10' from the back wall)

My T.V. and center channel are in the middle of the front wall...center channel is the same height as my fromt standing speakers, but below the T.V.

My side surrounds are on stands which make them within inches of ear level.

My rear surrounds are going to be (center of speaker) 7' off the floor...due to the fact they we behind my bar and dont want anyone knock'n their heads on em and making them fall.

So what I am trying to figure out is the distance, backwards, from the seating position to my side surrounds, and the distance from each side wall for my rear surrounds.

This 7.1 speaker placement and any other placement is making my head spin....everything talks about 90-100 degrees from listen center, 120-130 degrees...etc...how in the heck do I measure this....lol Why cant there be anything with measurements, etc....for placing speakers. I googled, yahooed, etc...could not find anything "degrees'

I appreciate any help, tips, and insight that anyone sends my way. I am talking pictures of the process, just need to load em on the computer and post them....they will be soon hopefully.

Thanks a mill,
Jeff

Here's a link with a diagram of how their new Audyssey system works. Use the angles as a reference but if your room setup doesn't allow you to place the speakers exactly where they recommend, just try to come close.

Thanks again everyone...I am in the process of getting the picture to post. My rear surrounds are going to be (on the back wall) two feet from each side wall. Does anyone think that I should go closer to the sidewalls?

 

[sholling]

You may want to get those side surrounds up a foot or two higher.

why should I move em up a foot or two? everywhere i read it says ear level for sides. again, im sorry just dumb to this placement stuff

 

[j_garcia]

Side surrounds that are bipolar should be above the listener. Monopole surrounds should be at or near ear level. As for placement, you should try to temporarily place them before actually mounting them to see how it sounds and determine the best placement for your room like I mentioned in your other thread (stack up some boxes or a bookshelf)

Why....is Adam a pain in the ole a$$ too?

Here are the pictures finally:

The back wall where the rear surrounds are going…you can see the speaker wire hanging down. I pulled wires for 6.1 and 7.1, just incase I don’t have my two rear surrounds by the time this is finished

The front right of the wall where T.V. is going

Front wall center

Rear right wall

Another picture of back wall

Left side of front wall….the reason there is insulation is cuz the furnace is on the other side, and “trying” keep the sound down a lil

Right side of front wall…..there was a wall there, but decided it would be to “closed” if I didn’t open it up….to turned into a lil countertop. When I have poker games in the other room, everyone and talk without walking up to the “door”. I have it roughed in for a door, so when the time comes to sell I can throw up some studs, doors, and make it an extra bedroom

Another straight on of rear wall

Rear again

Front wall again

I just want to mention that the faced insulation that you are using is not as effective at sound attenuation as plain/unfaced insulation. I don't know how much the effectiveness is compromised but it's a no-no. Adding an extra layer of 5/8 drywall would be a great help in reducing sound from the furnace.

Exactly what I was thinking...

Yeah, something like that...

I agree with Alex, though regarding the insulation. Looks like its coming together. Just keep plugging away. Very interested in seeing finished theater.

The front and rear wall are exterior walls which needs faced....the insulation is left over from a lil while ago and thought I was used it. Why is it a big no no? R-13 faced and unfaced are the same thickness, same everything, so why would it be less effective then unfaced?

It not going to be a real "home theater" I am just trying to get the best sound out of it....

The paper transmits sound. If you have unfaced insulation on an exterior wall you need a vapor barrier on it. (plastic/polyurethane/visqueen or whatever they call it in your part of the country.)

 

[eurovw89]

It is block exterior wall

 

[eurovw89]

This is a townhouse....so part of the wall is exterior, and part is a joining with neighbors basement...so half of the front and rear walls are joining with the neighbors
