Subwoofers in Rooms: Effect of Absorptive and Resonant Room Structures
The room-loudspeaker interaction at low frequencies, where individual modes can be easily identified, needs careful consideration when flat response and controlled spatial distribution are desired. The methods for controlling low frequency response are loudspeaker placement, use of multiple subwoofers, use of absorptive materials, and specific to low-frequency acoustics, use of resonators. The effects of various types of resonators and absorptive surfaces are computed using FEM for single and multiple subwoofer configurations in symmetrical and asymmetrical rooms, indicating that taking both the symmetry of the mode to be controlled and the loudspeaker placement into account when placing the resonators and/or absorbers is needed for optimal results.
