EP2.3 Best sound at Show award for Axpona 2015

EP2.3, The Absolute Sound Editors Choice award winner

EP4.7 in optional Cocobolo finish

"The Emerald Physics EP4.7 speakers offer an extraordinarily believable 3D holographic sound stage. They have better than subwoofer-quality bass. The midrange is the complete package. The upper frequencies have state-of-the-art resolution. If you are looking for a full range, high resolution, high-performance speaker then you should hear the Emerald Physics EP4.7. Even if you are prepared to spend (a LOT) more, the Emerald Physics EP4.7 offers exemplary performance and destroys all price-performance ratio benchmarks extant.". The $7200.00 pair are on sale now for $4699.00 in Black Tri-coat- Only 2 pair left

"They are keepers. I mailed the check and added them to the 
reference system."

The EP4.3 is now Steven Stone's, from the Absolute Sound, new Reference speakers. He said:

“Changed my (Reference) Genesis 6.1’s for the EP4.3’s which I have used in three different rooms. In every room, and each was quite different, it was easy to set-up and dial-in the speakers so that they imaged so well that they disappeared”

Overall Rating: 10 LPs

Eliminating the room

Emerald Physics has developed a method to control a speaker’s dispersion pattern in order to minimize room interactions and thereby eliminate most of the room’s sonic signature. Our patent-pending BDC (Broadband Directivity Control) technology is a turning point in the history of loudspeaker design. Until now, speaker / room interaction has been one of the major problems in home audio systems. Conventional speakers have wide dispersion and an omni-directional pattern in the bass range, sending large amounts of sound energy toward the room boundaries, which are reflected back into the listening space with a time delay. These are known as early reflections, which color the sound of the original signal. The omni-directional bass pattern also excites room resonances in all three axis which tends to cause the boomy, ill-defined bass commonly experienced in many systems. The solution is to create a speaker with a more narrow dispersion pattern as well as a more consistent dispersion     angle across the frequency spectrum. Listening to mainly the loudspeaker’s direct field eliminates most of your room’s sound, creating a consistent and natural playback performance even in difficult rooms.

We now have a showroom in Broomfield, Colorado 80020 where we make the speakers. Multiple complete systems are on display. Auditions are available with appointment. Call me at 770-667-5633 to set up an appointment.
