Long wall or short wall

Generally, sonics stand a better chance if speaker placement is on the short wall. There can be acceptions as I believe the Dunlavy SC-IV's were purported to be better on the long wall.

I believe the primary reason is to minimize room reflections from the back wall is perhaps the primary reason. In addition, I believe that the narrower side walls may help ensure sound travel from front to back.

I also own a pair of 10T's. But I've never tried them on the long wall simply because my rooms have only been around 12.5 to 13.5 ft in width and thus not allowing for much space behind the listening chair and the back wall.

As for selling the 10T's for a pair of Vm5A's. Do you even have to ask?

The 10T's are an excellent speaker top to bottom. I've never listened to them, but the possibilities of what the Vm5A's can do sound just too overwhelming to pass up.

Thanks for the confirmation, Dan_ed. For speaker placement, might I suggest you try applying the Allision rule?

All measurements are taken from the front center woofer driver.

The Allison rule basically states that the distances from the woofer to the floor, woofer to the side wall, and woofer to the back wall should be as different as possible. To accomplish this, one would apply the following equation:

Middle distance squared = shortest distance multiplied by longest distance.

Implementing this rule along with toed-in speakers so the tweeters and midranges are pointed directly at the listener's ear could be an excellent starting point toward obtaining pinpoint imaging and 3-d soundstaging. And perhaps even the ending point.

For example, in my case, the woofer front center is:

o 3.5ft from side wall.
o 2.0ft from floor.
o 6.0ft from back wall.

3.5 squared = 12.5
2.0 x 6.0 = 12.0

12.5 is pert near equal to 12.0

My ears are now about 6ft from the mid-range/tweeter heads so I am definitely listening more in the nearfield.

I mentioned this to a buddy who owns Magnaplanar 3.6's (a bit harder to measure). He wrote back stating that he was no longer able to get to sleep at night because the new placement transformed his system's sonics.
