This thread is really interesting! I found it from the Purifi thread on Diyaudio. I use Heil AMT in open baffles crossed over with a 15" woofer, so a lower crossover frequency would be great. I wonder how big the contribution is of reducing acoustic shortcircuit by the Wings. E.g. what if you would make panels on the side of the AMT perpende iculary? And could it be beneficial to add a panel on top of the AMT, from left to right, pointing straight up? Furthermore, it could be an Idea to cover the magnet structure more. I heard this causes unflatness around 5-7 kHz... This calls for some experiments... Fedde
