AB  - Room modes are one of the greatest concerns when considering accurate sound recording and reproduction. Low-frequency (LF) absorbers are used to mitigate modes, however, most independent testing laboratories are only large enough to measure accurate absorption results above 160 Hz but not below. One lab is large enough to be accurate down to 40 Hz. A new LF absorber was designed to complement the capabilities of an original LF absorber. Summary: the type of absorber, and its location and orientation in a room, are all critical to LF absorber effectiveness. Without standardized laboratory absorption testing in a lab capable of accurately testing down to 40 Hz, it is difficult to state conclusively that low-frequency absorber products perform as claimed.
