![]() ![]() So, while the wool baffle experiment worked well for a flat baffle, it may not work so well for a horn-style baffle where the pressures are higher. ![]() One concern I would have is that horns improve the dynamics of speakers, and the foam will dampen the dynamics, so you might gain some benefits at the baffle edge, but loose midbass dynamics (this is why back horn or tapped speakers have little adsorbent material in them). This will do a lot more to reduce cancellation, and it will load the back of the driver the same as the front of the driver. One way to fix this is to create a horn like baffle for the rear of the driver. I agree with what someone else has said, which is that the rear wave is more important than the front wave and that you will still have dipole rolloff probably at a higher frequency than what you think. This style of baffle will avoid resonances caused by parallel wings. ![]() However, if all you are trying to do is create a different style baffle which lowers the cancellation frequency, then this could work. My first comment is that the horn that you are proposing will not load the driver to 100 hz. ![]()
