Long wall or short wall

I can't add much more to what Stehno has posted except to say that if you don't have decor restraints try them on the long wall. I have moved mine around several times and I do find that I like the sound better on what would be the short wall. My room is 15' x 30' with a 6'x15' jog that makes the room an ell. This gives me 21' along the "short" wall. The speakers are 7' apart and 3' off the back wall and I listen at around 8'.

I really like my 10t's, but Stenho has peeked my curiosity about the Vandy's. I'll have to find someplace close by to hear them

I agree with Sean's comments on Cara. For the price I have found it to be a very useful tool. I do have limitations with placement of speakers in my listening room due to a pool table at one end of the room. There are still many choices left for me and I have explored each with Cara and found that for each location Cara did find the best starting point placement for each speaker. Usually a staggard placement I would never have though of. Just to echo Sean's comments, Cara is a very good mathematical modeling tool. But all model goes-outs are subject to the goes-ins.

All of that being said, Cara can't listen for you. I have found that in my room a more conventional setup has worked best so far. I believe it is because of the 7' from each side wall to each speaker and also because of the softening of the 1st reflecting point waves.

I guess what I am saying is that long wall and short wall are relative terms when you take into account the magnitude of each measurement. For instance, in my case it could be said that I listen on the short wall but the width of this short wall allows me to reap the same benefits as long wall listeners.

And don't discount the imaging capabilities of the 10t's. They do require alot of power. I'm feeding mine 300wpc and have been advised by some that they need 400+ to really sing.
