After deciding that my Home theater system wasn't sounding it's best in my living room, due to it's large open area and lots of flat walls, basically an echo chamber. I placed an order from Acoustimac for DMD 2'x4'x2" panels. This was during the Hurricane Ian plowing through Florida, and Acoustimac still managed to manufacture and ship out the panels to me in about 2 weeks time. I am amazed and thrilled that they were able to do that. The panels came undamaged and in good shape. I installed all 14 panels and I recalibrated my system to the new room environment...and WOW!!! It made a huge difference! It's like having a whole new sound system. Thank you Acoustimac. This was money well spent.
