This test is an ongoing obsession of ours - to determine the most effective bass traps in real life situations. Unfortunately all the existing standardized test don't take into account frequencies below 100Hz nor do they measure them correctly or consistently correct. Therefore - test like these can usually help to clarify what works, what doesn't and which bass trap is "better".

This particular test was done in a treated studio 9m x 4,5m x 2,6m (LxWxH) - only parameters that changed were bass traps in 2 corners. Meassuring was done with a calibrated measurement microphone from the listening position with studio monitors and a sub (2.1 combination).

We measured 2 bare corners, then all the different types of bass traps in those 2 corners, covering roughly 85% of the corner (floor to ceiling). 

*Triangle Trap and Square Trap have no air gap behind them, Bass and Corner Trap have a significant air gap behind them. In the test CORNER Traps absorbed the deepest (room mode at 38Hz) and the SQUARE Traps performed best in overall bass absorption.



*This blog has changed to include only current production Anthill products. At a latter date more bass traps will be added including DIY options and foam options. From our earlier tests, smaller triangle and tube traps have very little effect on absorption under 120Hz (under 30cm deep or in diameter) and foam bass traps do almost nothing for bass absorption. The bigger - the better is the case and air gap can help with how deep the absorption goes.

Endgame goal - all types of existing DIY or manufactured bass traps (porous type) against each other in the same room with the same setup.
