With its pivoting titanium dome tweeter and 6.5 Polypropylene Cone woofer, the MK640 are superb in-ceiling speakers for home theaters or for listening to your favorite tunes. With power handling up to 150W, the MK640 also includes contour switches that let you tailor frequency response to your room arrangement, so you won't find yourself straining for more or less treble, midrange or bass output just because you don't sit in the "sweet spot." These elegant, flush-mount speakers are ideal for new construction and can be painted to match any décor. New construction brackets are available, and OSD speakers include convenient dog-ear brackets for retrofit applications. All OSD Audio in-wall and in-ceiling speakers are backed by a 10-year warranty.
Contour switches on many of OSD models allow you tailor frequency response to your particular room arrangement. You won't find yourself wishing for more or less treble, midrange or bass output from one speaker just because you don't happen to sit right between them.
Powder Coated Grille
Like many OSD in-ceiling speakers, the MK640 includes powder-coated grilles that resist rust. This makes these ceiling speakers ideal for bathrooms, laundry rooms or even covered patios. Keep in mind, however, that these in-ceiling speakers are not outdoor speakers and should be exposed to a lot of moisture.
For a retrofit installation, no construction bracket is needed.
