Dayton Audio MK402BTX Bookshelf Speakers

The MK Series of home speakers from Dayton Audio are the best way to add rich sound with elegance and sophistication. Built to last, the MK series makes it easy to listen to for hours and hours with it non fatiguing sound. Enjoying audio has never been this easy.

The MK402BTX offers the same fantastic sound quality and articulation as the original but adds the wonderful amenity of a wireless connection. The built-in amplifier on the MK402BTX is able to provide up to 80 watts of max output power, easily enough to power these speakers. The MK402BTX also allows you to change tracks, volume, and even pause/play songs from the speaker itself.

Majestic Design

The MK402X 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.

Keynote Performance

The MK402X are engineered to disappear and deliver a transparent lifelike performance. Each speaker has an incredible wide listening field to provide excellent detail from any position. The unique faceted baffle on the front of each speaker does more than look beautiful, but actually help compensate for excessive treble, providing a smooth and non-fatiguing experience.

Control At Your Finger Tips

The MK402BTX can be controlled via the controller atop the active speaker. This controller allows you to set volume, start and stop playback, and change the source.

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.

Felt, And Heard

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.
