Hi, didn't get it answered in another place I asked, so trying again - If there is a square room, say 25 * 25, but the system is installed towards one end of the room, in a say, 25 * 11 rectangle, leaving the remaining 25 * 14 furnished with other furniture, will it still cause the problem that square rooms do (because, in this case, even though the room is square, the system is in a virtual rectangle at one end of the room)

But shouldn't it reflect of one wall quicker than the other, thus not creating those waves? Also in a rectangular room, if you have a system in the centre, and then move it towards one wall, away from the other, won't your sound change?

Hello, bonzo75. My experience with doing something like this yields one speaker that is overloaded in lower registers and lower mids, whilst the other speaker tends to be lean in the same areas. You will still have the same issues as in a square room but the nulls and loading will just change locations with other issues rearing their ugly head. Especially onh spacial locational cues with the sound stage.

The standing waves form based upon frequency and room dimensions, does not matter where you place the source. You can place a speaker in a null to help offset the null locally, but it's still there...

My main concern is that you specify a too little area for your system - you should get 15x25 for your system. 10x 25 for furniture. The 25'x25' are very large dimensions, it means that only axial modes will be of interest. If you have doubts about it read F. Toole about the the many studies on "golden" dimensions in his book "Sound Reproduction". BTW some full range dipoles can operate miracles even in critical square rooms. Will you be allowed to use bass traps in the room?

The Hunecke - I doubt you will find it googling Huneicke or Heineken - ;) http://www.hunecke.de/en/calculators/room-eigenmodes.html will be of help only after you have the speakers in the room and take a few preliminary measurements, and you will have to learn how to use it and coordinate it with measurements. All IMHO, YMMV, I am not an expert.

EQ will help bring done peaks but is of limited value if the null is from a room mode. The latter can be very deep...

It is why I think no one can risk a valid opinion without having all the details about the type of building, door cavities, windows placement type and surface, and many others.

Hi yes, I am planning a future move. I put these questions when I see an attractive floorplan that might have certain possible issues. Helps me keep at the back of my mind what to consider.

Speakers generally like to have a symmetrical placement, the same space and construction behind each, I would also look for a high ceiling, no domestic room will be perfect a large room will give you more options.
keith.

A large room in central London :eek:

Hey Bonzo, just out of curiosity are you able to take a pic of your intended room, then perhaps we could better understand it?
Or better still, send someone an email and draw up roughly the placement of your system, then let the "panel" experts help by sketching the best placement for trials.
I strongly believe as time passes by based on this initial sketch, you will find the optimal placement. And this will all be judged by YOUR ears and not some fancy gimmicks...

Just a thought, it had worked for me back in home town.
Cheers, RJ
