Developed for our own loudspeakers, the DFR-8 solves the shortcomings of full range drivers with completely unique design solutions. You can read about them in the
white paper.

The result is no mid-range/treble shout. Needs no tweeter. Has real bass. 96dB efficiency with 1 watt.

This is the actual driver used in our
High Definition Tower speakers and the NFX.  It is now available for the DIY speaker builders.
