The quest for perfect sounding audio in your house can be frustrating as virtually no space in a home is designed with sound reproduction in mind. This can lead to constantly tinkering with acoustic treatments, changing speaker placement, or even rearranging furniture (which may not go over too well with other members of the household). Instead of wasting time fiddling with your system or room, take control of your sound with the MQ112 Environmental Equalizer and spend more time listening to your music.

In the relentless pursuit of perfect audio, we understand the frustration of adapting your living space for optimal sound reproduction. With the MQ112, you can make changes to the music itself so that room acoustic problems can be overcome. The results can be stunning and can make even a great sounding stereo system sound even better.
