JBL Control SB-2

The Control SB-2 provides low frequency reinforcement in subwoofer/satellite systems. The Control SB-2 is ideal for foreground music and music/paging systems in restaurants, retail establishments, theme bars, music cafes, health clubs, and other indoor applications.

The unique slot-load vented design provides acoustic low-pass filtering. Compared to traditional bandpass subwoofers, the SB-2 offers superior musical clarity and bass impact. The satellite outputs are highpass filtered, reducing overall system distortion by eliminating the need for the satellite speakers to reproduce frequencies in the low bass range.

The satellites operate more efficiently, maintaining excellent midrange clarity and realism in music and paging. The high-pass filtering also allows a greater number of satellite speakers to be paralleled in the system by increasing the impedance the amplifier sees in the subwoofer range. The stereo inputs are 8 ohms each.

The combination of the satellite high-pass filtering, the acoustic slotload filtering and a built-in 2nd order low-pass crossover network results in smoother overall system frequency response and virtually eliminates the “muddiness” typical of other subwoofer/satellite systems by reducing frequency overlap in the low midrange.
