I am going to be building a Home Theater out of our 2 car garage soon, and I am thinking of building a new sub. This is what I am thinking of: 1. Build out the garage wall 5' deeper, and 17' wide with a 8' ceiling (garage door will become a screen wall with my 3 La Scalas and 2 Heresy HIPs behind a AT screen). 2: The garage and new room will be double wall constructed with 1 layer of OSB, 2-3 layers of sheet rock with Green Glue. The ceiling is currently 9' and will have about a 6" thick additional ceiling due to 3 layers of sheet rock and Green Glue. What I am thinking of doing is using the whole addition room for a IB type sub but make the exit point of the box into a horn. I would build boxes that would enclose the 5 front speakers and seal them into the front wall. The front wall would only have a hole in it for the sub/horn to exit the room, and the AT screen would conceal the whole affair. I currently have the PSA Triax sub and it is great. I figure when I move to the larger room I will need more subs and I would like to have a sub that will give me the low frequency performance of the Triax (or better) without using a 4000w continuous 8000w peak amp (x2 if I have 2). I would like to be able to do it with a single amp of under 500w if that is possible. I was looking at building dual Gjallarhorns, but I am thinking that this might be easier to build and give me the same performance.
