Unless you have a professionally designed and treated room, TubeTraps from Acoustic Sciences Corporation are absolutely indispensable to improving your system’s sound. They are able to solve a wide range of acoustic problems with strategic placement and orientation.
Boomy bass can be cured with a pair of 16″ Full Rounds in the corners behind the loudspeakers. Placed along the sidewalls between you and the loudspeakers, TubeTraps kill unwanted sidewall reflections, prevent flutter echo, and aid in diffusion.
A single TubeTrap in the center of the wall behind the loudspeakers can expand soundstage depth.
There are lots of questionable acoustic products on the market, but TubeTraps are the real deal.
