Subwoofer_boundaryLoadingTake advantage of free acoustical power: always place subwoofers on the floor behind the screen – NOT on a platform with the screen loudspeakers. Floor-positioned subwoofers take advantage of “half-space” loading, which increases radiated power by about 3 dB, WITHOUT adding any extra amplifier power. Even better: place the subwoofers on the floor AND push them all the way back against the solid wall behind the screen. That is called “quarter space” loading, and results in about 6 dB greater SPL, without using a larger amplifier. The very low frequencies produced by the subwoofers have no problem going right through any draping or masking below the screen.
