Product Details

MK Sound MX-250 Black 12" Powered Subwoofer, Model MX250BK

The MK Sound MX-350THX and MX-250 subwoofers use dual ultra high performance, long throw 12” magnetically shielded drivers, capable of extremely high output with superb articulation, clarity and authority. The onboard power amplifiers employ MK SOUND Balanced Push-Pull Dual Drive Amplifier technology, which incorporates proprietary Headroom Maximizer IV circuitry to prevent amplifier clipping and the resulting unwanted audible artifacts. Delivering massive power, these innovative amplifiers give you extremely clean sound and extraordinary articulation, along with enormous output and incredible dynamic range. MK SOUND’s Deep Bass sealed-box design produces significant low frequency extension, with in-room response flat to well below 20 Hz for lifelike power and authority that other subwoofers simply cannot match. MK SOUND’s Push-Pull Dual Driver Configuration delivers a major improvement in bass detail and articulation by virtually eliminating even-order harmonic distortion and doubling the sound power per watt of amplifier power, for 6 dB of additional output! The linear phase lowpass filter optimizes speaker performance and simplifies set-up. In virtually all cases, regardless of the room, listener location or speakers, the overlapping acoustic output of the satellites and subwoofer will sum to near perfection for a seamless transition between the upper range of the subwoofer and the lower range of the satellite speakers.
