•Higher-level foreground music in bass heavy applications such as dance floors, amusement arcades, or loud bars: use one pair of EVID™ 6.2’s for each 12.1P.
•For example, a large hotel might use eight 3.2’s and two 12.1P’s in the dining room, eight 4.2’s and two 12.1P’s in the lounge, four 6.2’s with two 12.1P’s surrounding the dance floor, 6.2’s around the pool, 6.2’s or 4.2s with or without 12.1P’s in the lobby, and 3.2’s in the corridors.
Characteristics of All Subwoofers
While subwoofers do radiate sound omni-directionally (in all directions) and the sound is generally non-localizable (one can’t hear exactly where it comes from), subwoofer sound level still drops off the farther one moves from the subwoofer. The highest output and best room loading are accomplished with the subwoofer mounted in a corner at a three- boundary junction (wall/wall/ceiling or wall/wall/floor, an arrangement also referred to as 1/8 space). Mounting at a two-boundary junction (wall/ ceiling, or 1/4 space) produces three dB less output, and mounting in the middle of a room in the ceiling (1/2 space) reduces output still another three dB.
Subwoofers produce large amounts of long wavelength low-frequency energy. Every object has its own resonant frequency, and long wavelengths tend to excite large objects (like walls, floors, doors and ceiling panels). Anything loose in or on a ceiling or wall will buzz or rattle as a subwoofer’s level is increased. Most of these can be isolated and fixed with small, strategically placed bits of foam tape. Others may require driving additional nails or screws and perhaps some caulking to dampen their sympathetic movement.
