The subwoofer features a threaded pole receptacle for a positive, wobble free connection to a threaded speaker pole (included). Remote gain control capability is offered via a potentiometer (not included) connected to the on-board Euroblock connector. In an installed application, multiple K Series speakers can be "daisy-chained" for total gain control from a single remote pot. Auto-standby mode is engaged after 5 minutes of inactivity. Extensive DSP 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 spacially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat bandpass 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, first introduced on our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.
