I know among audio enthusiasts, you should adapt your listening environment to your audio system, not the other way around. Your speaker system should never be crammed in the corners to avoid unwanted reverberation and annoying boomy sound. But I have a tiny living room and had no choice but to adapt my audio system to my listening environment. So my speaker system is unfortunately crammed in the corners. Then I stumbled upon Acoustimac online and could almost hear them saying, "I think we can help you with that." Bad timing on my part, I just had abdominal surgery yesterday and my doctor's orders is to take it easy the next few days, so I can't mount them on the wall yet. Still, with placing them behind the speakers, there was a significant difference. That annoying boomy sound is now gone. Five stars for Acoustimac doesn't seem like enough praise for delivering a highly functional product equally matched by their eye-catching beauty. They are now the visual centerpiece of my living room. Regarding customer service, the Acoustimac tech sent me a courtesy email with his suggested plan for the visual layout. He did an excellent job in design placement of the musical instruments so there's not a large volume of black space. As for price, I did a healthy amount of stare and compare with other vendors. Having them now in my living room, I have zero doubt Acoustimac gave me the most bang for my buck. The shipping time time was swift and the packaging was top notch. I read the instructions and it looks pretty simple. So I'm really anxious to get them mounted on the wall after I comply with my doctor's orders. I would definitely recommend Acoustimac to family and friends. So thank you, Acoustimac, for delivering a great product. To loosely quote a line from the movie King Kong, "it wasn't the airplanes that got him, it was Acoustimac Beauty that killed the "boomy" beast.
