hi
look at the absorbants, resonator section, "roundbasscorners"
cool stuff
available in many colors
120cm high; 22kg
Hemholtz resonator inside.
helps my demo room 2 going lower in FQ with less room resonance
ideally you need 4-8 of these ! stacked by 2 vertically, in each corner
it sucks down the corner increase and helps increase the nulls.
i also have a raiser. can't watch a movie without a raiser
much more cinematic.
