Altec 604 D Enclosures

[David Yost]

Charles,

Are you able to take advantage of the room corners? In other words, might you be able to "build-in" large floor to ceiling corner IB boxes canted approx. 30 degrees towards the listening position? If so, this would be my first choice and you could add eq or series resistance to balance the system. This layout also gives you maximum boundary reinforcement while minimizing diffraction and creating a pseudo early-reflection-free zone, not to mention using the minimum floor space. Also, if your corner walls are sufficiently rigid, you may be able to get by with building just a well reinforced front baffle screwed and sealed to wall, floor and ceiling furring strips -- it doesn't get much easier than this. A 4' wide (standard for plywood in the USA) baffle set at 30 degrees will yield about 25 cubic feet.

Building a large enough closed box will also mean that you can stop agonizing over your speakers' TS measurements -- they are what they are, and as long as the pair are more or less the same, you will be in business.

Best wishes,
David
