Carbon Series Controlled Directivity Open Baffle speakers with Carbon Fiber Midrange & Polyester tweeter
Single amp operation
The new EP3.8 is the baby brother to our top of the line EP2.8 and smaller EP4.8. Essentially, it is the EP4.8 with no 15" woofer that is designed to work with a subwoofer.
Cutting edge sonic performance establishes a new level of realism & dimensionality at anywhere near its Internet Direct cost of only $6,495.00 a pair.
Here is what one customer said about their 3.7 to 3.8 upgrade: "Walter, just installed the new drivers and crossovers. Been listening for a couple of hours. WOW! WOW! WOW! The new driver hits so much harder yet is so smooth. Blacker, more silence between notes, complete non fatiguing. The most non fatiguing speaker I have ever heard. The best tweeter I have experienced in my home. It's easily twice the speaker it was before. THANK YOU! Best, David Elrod (Elrod Cables)
The upgraded EP3.7 is now called the EP3.8. The new Carbon Series EP3.8 is a state of the art 2-way speaker with 95dB efficiency that runs from a single amp.
If set up as single amp, full range network configuration, it is 95dB efficient. It can then be upgraded in the users home to either bi-amp or tri-amp operation with your subwoofer. In addition to an extra 3dB of efficiency in triamp the new EP3.8 offers greater dynamics, improved midrange and bass transparency as well as resolution.
Our controlled dispersion design means that the speakers are not room dependent and work in all rooms.
The new custom designed Emerald Physics Carbon Fiber Series 12" midrange drivers provide increased speed, transparency and resolution. Midrange smear is completely eliminated. Compare the EP3.8 to speakers selling for many times their Internet Direct price.
In addition to the new Carbon Fiber midrange the EP3.8 uses our Emerald Neodymium Polyester-Diaphram compression tweeter and an improved crossover over the original EP3.7 that it replaces. It also now is wired with Wireworld OCC cable.
The 3.8 is designed to work as close as 2 feet from the rear wall and with only a single amp.
In single amp dress it is 95Db efficient so small amps (20 watts or better) will work quite well. Once bi-amped or tri-amped (with your sub) the efficiency goes up to 98Db for even great dynamics. Pick a large amp for the mids and any amp with over 10 watts for the highs. Use an Emerald, 200 watts per channel, EP200.2SE for the mids as well as system preamp and our 100wpc EP100.2SE for the highs for a perfectly sonic matched package. In addition, the speakers have our new upgraded Natural Macassar Ebony finish, a nice upgrade over the black Tricoat of the older speaker.
The included DSP2.4 or optional DSP2.8 digital electronic crossovers improve the sonics even further by fine tuning the frequency response as well as extending bass response from 45Hz and down to the subwoofer.

At the AXPONA 2014 show part time audiophile said of the older EP3 system:
"Walter Liederman of Emerald Physics ought to be pleased with himself. He’s managed to shepherd to market a relatively affordable, reliably excellent, state-of-the-art audio experience in his Emerald Physics lineup."
"The speakers are also DSP-controlled, and while that gets you in the ballpark of acoustically optimal more often than not, is still looked askance by many. But the perception of downsides are all just that. Perceptions. The proof of the pudding is in the eating. And this is a tasty little dish."
"On the whole, this room was quite convincing. Walter was offering the entire system (minus the PS Audio DAC) at just under $6,000 as a show-special, trying to demonstrate how great sound doesn’t have to cost more than a BMW. I’d say he nailed it. The sound here was very dynamic, open and expressive.
The fact that this was one of the busiest rooms at the show says that I’m not alone in thinking this."

Here is what Audiophilia said of our EP3 at the Newport Beach Show:
The day’s walkabout was a discovery of excellent sound (a couple in my Best Of), new kit and exhibitors bending over backwards to make your room visit fruitful. So accommodating. They were more than happy to give a quick precis or a lengthy tome about the topologies and designs.
"A speaker managed from Maui (the owner had a big smile on his face) and manufactured in Colorado caught my ear. Emerald Physics had their CS3 MK2 ‘Controlled Directivity Loudspeaker’ playing Handel harp concertos via a complete system, including Rel T9 powered subwoofers and their own electronics. The price for the speakers and subs was less than 5K. For that price, these speakers are an absolute steal and should be heard by any audiophile on a strict budget who wants Champagne sound. Dipole technology with point source design. No grain, no hash, well balanced and very dynamic were among my notes. And the two subs were integrated as well as any."
