Post Subject: Mid Bass ProjectPosted by msaudio on: 6/17/2010

Jbl came out with a new type of horn design a few year back and it looked like it had alot of good features. The top wall of the horn was curved up while the bottom wall was curved up then down very steep and it was still a 93-46 degree horn. You could use these features and it could correct a lot of resonance problems with the horns that most people use. With the narrow bandwidth you are going to use, you might get away with a single horn with both of your 15 inch woofers mounted on the same baffle, but used in stereo mode. This will give you more room to increase the size and lenght of the single horn, but i would not use myself above 80 Hz. I will help instead of badmouth your project because after it is compleat you could still use for low bass, if your not happy with it. I have no idea of the sqaure footage in your attic, but a good idea would be to leave the back of the baffle open to the attic and use it for your inclosure. make a triangle baffle from wall to ceiling and seal it for your back presure. This also helps for weight displacement so you won't have no sagging in your ceiling. Preaching Horn Religion MSAUDIO
