The new EP-3.7 is the upgraded version of our EP-3.

The EP-3 represents the next generation in our dipole technology with its point source design. There is not a single part from the original series in this new EP-3.7 upgraded version.

The EP-3 employs our new Emerald Physics EP12.1 custom 12” woofer/midrange and tweeter point source driver with our high end Polyester tweeter as also used in the EP2,7 and EP4.7 models.

It comes with our $US600.00 external Special Edition passive crossover and the beautiful $US1200.00 8 stage Tri-coat automotive finish in any of 5 colors.

The Emerald Physics DSP2.4 electronic crossover/EQ provides DSP controlled subwoofer crossover and equalization for the system. Our controlled dispersion design eliminates most listening room anomalies, allowing the EP-3.7 to sound great in virtually all rooms.

With a powered subwoofer you can have a fully bi-amplified system that can fill almost any sized room with superb dynamics and bass into the 20Hz range. Our beautiful new cosmetic is a major upgrade. High Gloss Tri-coat is standard. Custom Cocobolo and Rosewood hand painted Tricoat is also available as a $US600.00 option.
