The SoundPlank is Essential for any listening environment and are the most effective tool for managing perimeter reflections and keeping the RT-60 of your room optimized.
The SoundPlank manages mid-range and upper bass is absorbed while the integrated diffuser strip keeps your room bright and not over-damped.
Other acoustical panels are large and cover lots of wall space and are marginally flexible to any doors, furniture, windows and other features of your space.

The SoundPanel’s slim design and “grid” layout have a larger impact than an individual unit. The “edge effect” substantially improves the sound absorption characteristics. Don’t be fooled by the “value” of larger panels from competitors!
The total is greater than the sum of the parts.
