Room simulation software for multiple subs ?

[Paul W]

Looking for software recommendations to help with the design of a new AV room. Primary interest is below 300Hz, minimum 4 simultaneous subwoofer locations, 8 much better, 16 or more simultaneous sub locations would be ideal. What's out there?

I'm not aware of any software that will do what you ask, but there is an excellent article from Harman called "Subwoofers: Optimum Number and Locations ". It's well worth the read if you are considering multiple subs.

Click on "White Papers" and the "Subwoofers: Optimum Number and Locations"

CARA labs makes a product that will do that nicely, and RPG acousitics will probably do so in their Room Optimizer package, which is oriented towards LF room and speaker position, listener position analysis. Owned that for years.

The more LF source you have handling the same signal and the further apart in room position, the more comb filtering effects will exist in the upper bass and lower midrange.

Cara might be able to do it..

"The more LF source you have handling the same signal and the further apart in room position, the more comb filtering effects will exist in the upper bass and lower midrange."

It's the difference in distances, not the distances, that matter, as I'm sure you know.

The Harman paper referenced above explains how positioning subs on opposite mid-walls eliminates all odd-order room modes in the central listening area.
