Full Description

High Quality Construction

The QSC KSub offers unparalleled performance with its dual 12" subwoofer drivers. Premium-grade materials and advanced construction processes have been used, as well as extensive DSP processing is employed throughout, providing levels of sonic clarity and total output that defy the system's size and weight.

Flexible Connectivity

The QSC KSub offers flexible connectivity options with dual balanced female XLR 1/4" line level input, dual balanced male XLR full range line level out, remote gain control and locking IEC power connector.

Rugged Housing

The KSub features a rugged birch plywood enclosure with a professional appearance that is at home in any application. The internal rigidity offers an additional measure of sonic clarity. Ease of transport and long term durability is ensured with the KSub's ergonomic aluminium handles and 4 casters.

Extensive DSP enhances system performance

• DMT™ (Directivity Matched Transition) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.
• Intrinsic Correction™, first featured in our high-end line-array products maps 65-75 spatially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat band pass target. The result is a speaker that behaves equally well across the entire sound field.
• DEEP™ and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.
• GuardRail™ protection protects both the amplifier module and your performance from unnatural and destructive clipping.
