The MK402X offers fantastic sound quality and articulation as the original but features a more refined crossover that produces smoother highs. The built-in amplifier on the MK402X is able to provide up to 80 watts of max output power, easily enough to power these speakers. Enhance your music listening experience with this pair of two-way vented bookshelf speakers.


Beauty More Than Skin Deep

The MK402BTX features an attractive textured, black vinyl finish that stands out at first glance. The cabinet offers a unique geometric design for the baffle that sets it apart from much more basic speakers in its price range. The grill is removable and made of a high-quality black cloth that discretely obscures the most appealing features of this design, the drivers.

Elegant 3/4" Silk Dome Tweeter

The 3/4" tweeter is elegant with a very airy top-end that can be appreciated by anybody that enjoys the delicate side of music that is often left behind by most speakers. The dispersion from this tweeter provides a life-like ambiance that truly sets a scene for the music.

Impressive Low Frequency Extension from a 4" Woofer

The woofer is able to play down to the 60 Hz range with ease. A 4" woofer playing low frequencies would normally limit the upper-frequency range, that is not the case here. The woofer plays through a large portion of the vocal range, adding coherency and smoothness to music.


The built-in crossover creates a non-fatiguing, enjoyable listening experience. It features a 3.3 kHz,1st order high-pass, 2nd order low-pass filter. The 7-component crossover uses asymmetrical slopes to help blend the two drivers in a more musical way. The crossover now has a flatter treble response that delivers a smoother high-end. Terminals feature 5-way gold plated posts for simple and secured connectivity.
