DEEP™

DEEP (Digital Extension and Excursion Processing) is an exclusive QSC process that allows K and KW Series loudspeakers to deliver far more undistorted low-frequency output than could be produced by conventional means.

DEEP begins by applying an equalization boost at low frequency. Certainly many loudspeaker systems do the same thing (there's nothing new about this). Some even take the next step and apply limiting to reduce the amount of EQ boost as the amplifier approaches overload. The effect may be better than nothing at all, but this process does create audible "pumping" and unnatural high frequency reductions at higher performance volume.

DEEP employs sophisticated digital signal processing to identify and reduce only those brief, transient low-frequency peaks that can cause woofer over-excursion or amplifier clipping. Reduction of the transient peaks is nearly inaudible and allows the average low-frequency output to remain high. The result is an astonishing amount of low-frequency output, previously impossible to achieve from compact, smaller-format speaker systems.
