Overview:

The DT Series of custom install speakers offer exceptional sonic performance from speakers that seemingly disappear into a wall or ceiling. Definitive Technology’s high definition drivers with polypropylene mineral-filled cones and rubber surrounds produce a clear, natural sound. Ceramic coated annealed aluminum dome tweeters reveal even the most delicate detail in recordings. And all DT tweeters have low-diffraction swivel mounts (except the stereo DT 6.5STR) that help improve dispersion, overall midrange and off-axis response.

Disappearing Grilles (with a perforation size a mere .6mm) use neodymium magnetics for fast, tight attachment. Round models are the same cutout size as DI size equivalents, while rectangular models are new sizes. Optional square grilles are available for 6-1/2" and 8" models.
