Hey there, I have a room where I have installed rear 8 inch speakercraft ceiling speakers. Im wondering if I should use the same speakers for the front, So that would be 4 speakers in the ceiling, a Sub, and a center speaker in my entertainment center. IS that a good setup? If anyone has any ideas let me know. TY

Ideally one would use the same speakers all the way around. That being said, it is most crucial/critical that the front sound stage be timbre matched (same brand and/or model) - the rears being used mostly foe diffuse sounds and ambient effects. In your case I think I would opt for 2 fronts and a center of a little higher caliber if you can swing it financially. Subwoofers if crossed over properly will give you low bass and frequencies that are omnidirectional and matching is not really necessary. Remember the most important speaker in a good surround set-up is the center channel as that is where ~80%-90% of your sound comes from (ie. dialog)

Default Vertical placement of surrounds/rears

I have a small 11' x 11' tv room.

I have read through the first posts of this thread and have my 7.1 speakers arranged as suggested as far as an overhead view is concerned. The angles of my speakers to viewing position are very close to the diagrams

What happens to the quality of the sound field if you have to raise the surrounds/rears up to the ceiling? Most often you will see the suggestion that the surrounds/rears fire across the room (parallel to the floor). In my case I have no choice but to mount my surrounds/rears at ceiling level and angle them down so that they intersect at a point 2 feet above the ears of someone in the center viewing position. Because the room is small the required angles are fairly steep.

Thanks,

As surrounds are typically diffuse ambient sounds, as long as you calibrate volume/signal level with either Audyssey or an SPL meter you should be just fine. If you are listening to SACD or DVD-A maybe you might note a small positional imbalance.

Add to this description to Timbre match use the same size speaker/make/model for a matched sound-stage. If it's not possible to have all the speakers the same, at the very least the Fronts and center should be matched.

Same distance as your display panel to keep the soundfield seamless and accurate.

Default huge room....Help!

i posted this on AVS also, but am getting no love. thought i'd ask here!

i read through a ton of these pages and some others and thought i'd run my upcoming configuration by you guys and get some feedback. my room is larger than anything i've read about so i'm a bit concerned as i can't afford to get into the kind of power i'd like to. here goes....

basement is 24x29. tight insulation walls to ceiling. 1/2 sound board with 5/8 drywall walls and ceiling. room is pretty much rectangular with rubber padding and short shag carpeting. pretty wide open as this is our HT/Media room. the system will get used 90% for TV/HT.

i already have Marantz AV7005/MM7025/MM7055 140x7 seperates (deal i couldn't pass up). i'm in LOVE with, and plan on purchasing the Paradigm Studio 100's V5, ADP-590's and the CC-690. here's my confusion......considering the small advantage i would get by Bi-Amping the 100's, should i just go 7.1 rather than 5.1 considering the overall size of this area? may put some Studio 20's in the 140 degree spots aiming at the head?

seating will be about 12' away, leaving 17' behind the seating area (pool table). if 7.1 is the way to go, should the 140 degree surrounds be on the walls or in the 140 degree line hanging from the ceiling CLOSER to the seating area?

Good article and applies excellently to a symmetrically built room for home theater purposes. Sadly today contractors don't really pay attention to the possibility that maybe one day the future family that will be occupying that house would like to have a home theater room, as is the case with our current house.

Here's the layout more or less so you guys can get a better picture. Our kitchen shares space with our living/dining room area so this poses some difficutly placing speakers.

The TV is placed in the upper right hand corner diagonally. There is a couch and a loveseat represented by the black solid bars. There is an end table under there which is marked by the double "T" looking icon which is where the powered subwoofer is placed under.

Behind the loveseat which is the left wall is the sliding glass door. Behind the couch which is the bottom wall is the window right behind the couch. On the top wall to the left of the TV is a countertop which extends into the kitchen area futhercomplicating things a little.

Attached is a drawing of the layout. Now of course this is not an exact diagram but it's fairly close.

So of course assuming with the information in the article, the center channel will be placed directly under our flat screen on the TV stand facing directly towards the center if possible and slightly upward. The front left and right will be placed on the wall with mounting brackets maybe about 1-2 ft away from the TV about the center height of the TV.

The issue I'm having left is where to place my rear speakers? Above the window and sliding glass door is drywall but I don't know if that's too high or not. Also if I do place them that high, how far apart should I place them? Obviously the couch is longer than the love seat so I'd like to try to get even distance sound from both rear speakers but according to the article it might not make a difference right? Also my receiver has a mic that I can place on the couch so it can calibrate all the speakers with all their distances and adjust any delay if needed.

Default odd shaped room

I've read the thread on speaker placement, but I have an odd shaped room. I know I don't have the option for perfect placement, but need some advice on what's my best option.

The room has 4 doors, a fireplace and cathedral ceilings (vaulted from 8' high on the side to 15' high at the peak. The TV can not be placed directly in front of the chair (main seat) or couch - because of the doors and fireplace. I have included a picture with a rough outline of the room.

Oh, I should say I have a Denon revceiver with BA 5.1 speakers....

Moving is not really an option .

Thanks very much!

Maybe we should have posted in a new thread rather than the sticky?

I doubt that our cases of room situation is completely unique never been addressed before right?

I have been looking over your layout and find resolutions very difficult, the only solution I can see, and it would present some installations difficulties ( both for wiring and mounting) but the only way out is to suspend your speakers ( and they must be mini's) or in-wall/ceiling type of speakers from your ceiling and angle them to your listening position. this is a labor intensive method as the wiring must be snaked thru walls and ceilings the mini speakers can be mounted on wall mts other than that I cannot see any possible solution that would produce an effective soundstage.

Sadly this isn't my house. It's a rental so I can't go ripping holes in the walls to put speakers. I do have mounts and screw holes aren't an issue and I'll be running speaker wire around covered with those plastic wire covers you see at places like Home Depot. I don't mind the look of those only because I know that they can easily be removed once we move down the line.

Unfortunately it won't be the best accoustical setup but it's better than listening everything thru my TV speakers. I also love do online gaming with my Xbox so I like the 5.1 setup as it helps in FPS games.

I'm thinking what I wanted to do is mount the front surrounds about halfway the height of where my TV is and about 1-1.5ft away from the TV. The center will go right on top of the TV stand right underneath the TV in the center pointed slightly upward towards the viewers.

The rear surrounds will be placed up either on the ceiling or near the ceiling about the edges of the couch and love seat. The subwoofer is currently placed under the end table in the corner opposite of the TV but now I'm thinking it's too far away and I might just place it right under the FL speaker.

I'm hoping that my mic that I use to calibrate my Sony blu-ray player/receiver will help adjust the right delays if needed so the sound can be as balanced as possible with my funky setup.

What do you guys think?
