EP4.8
EP4.8 is discontinued & sold out
Open Baffle Loudspeakers
With Carbon Fiber Drivers & Aperture Bass Propagation Technology-Single amp operation
The new EP4.8 replaces the EP4.7 that received superb press. It is better in almost all respects.
The EP4.8 / EP200.2SE system was just awarded a Best Sound of Show at the 2017 Axpona show by AV Showrooms.

The new EP4.8 is the baby brother to our top of the line EP2.8. Essentially, it is the EP2.8 with one instead of two 15" open baffle Carbon Fiber woofers. Efficiency is 2dB lower at up to 98dB versus the 100dB of its larger brother. In addition bass is flat to as low as 28Hz versus the 20Hz of the EP2.8.
Cutting edge sonic performance establishes a new level of realism & dimensionality at anywhere near its Internet Direct cost of only $8495.00/prSee the Audioflea EP4.8 show review at: https://audioflea.com/blog/reviews/hear-the-difference-emerald-physics-4-8-speakers/
Audio Flea summed with:
"The Emerald Physics EP-4.8 are a pair of must audition speakers for anyone considering buying a pair of speakers with a budget up to $50,000."
The reviews of the older EP4.7 were superb. This new speaker is a major step up with greater speed and resolution as well as higher efficiency
"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."
"They are keepers. I mailed the check and added them to the reference system."
Overall Rating: 10 LPs

The upgraded EP4.7 is now called the EP4.8. The new Carbon Series EP4.8 is a state of the art 3-way speaker with up to 98Db efficiency.
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. In addition to an extra 3dB of efficiency when triamping the new EP4.8 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 15" woofer and 12" midrange drivers provide increased speed, transparency and resolution. Midrange smear is completely eliminated. Compare the EP4.8 to speakers selling for many times their Internet Direct price.
In addition to the new Carbon Fiber midrange and woofer the EP4.8 uses our Emerald Neodymium Polyester-Diaphram compression tweeter and an improved crossover over the original EP4.7 that it replaces.It is also wired with Wireworld OCC cable.
The innovation continues in the Bass range with our unique Aperture Bass Propagation Technology. This proprietary system is used for the custom Emerald 15" carbon Fiber dipole woofers. This design increases low frequency power and linearity, while improving on the speed and articulation of the previous series.
The new Emerald designed 15" carbon Fiber woofer moves 80% more air than the original CS2.3 and CS2.7 woofers so a single 15 gets us almost as much bass as the dual 15's of the older models. The new 4.8 also adds our unique Bass Reservoir technology to our Apature Bass Loading to further improve bass response from previous open baffle designs.
In single or biamp amp dress it is 95dB efficient so small amps (20 watts or better) will work quite well. Once tri-amped the efficiency goes up to 98dB for even great dynamics. Pick a large amp for the bass and any amp with over 10 watts for the midrange/highs. Use an Emerald, 200 watts per channel, EP200.2SE for the bass and our 100wpc EP100.2SE for the midrange/highs for a perfectly sonic matched package. In addition, the speakersl have our new upgraded Natural Macassar Ebony finish, a nice upgrade over the black Tricoat of the older speaker.
The optional DSP2.4, DSP2.8 digital electronic crossovers or our Analog BOM bass EQ improve the sonics even further by fine tuning the frequency response as well as extending bass response from 35Hz down to 28Hz.
