DCM, makers of the "Time Window" speakers, is one of the most storied brands in loudspeaker history. Founded in 1974, DCM has made many well-reviewed and highly loved speakers.
DCM feels that they're able to produce high-quality speakers by hand-picking components, controlling the design and manufacturing processes, and "thinking outside the box."
The DCM TimeFrame Evolution is the modern update of the Time Window. The DCM TFE200 and DCM TFE100 are notable models from this line. The DCM TP250-CH and others have a 10 year warranty.
