"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."

The new EP4.7 is the baby brother to our top of the line EP2.7. It is the EP2.7 with one instead of two 15" open baffle woofers. Efficiency is 2 lower at 95dB versus the 97 of its larger brother. In addition bass is flat to 28Hz versus the 20Hz of the EP2.7. With its new Emerald Physics designed 12" point source professional driver system, the EP4.7 is a true 3-way, bi-amplified, dipole, controlled directivity speaker.
Cutting edge sonic performance establishes a new level of realism & dimensionality at anywhere near its Internet Direct cost of only $6995.00 a pair. This new EP4.7 model does not share a single part from the original CS2 series products. It has new outboard Special Edition crossovers, upgraded Emerald Physics DSP, custom Emerald Physics drivers, upgraded baffle, glod plated copper connectors and the much improved cosmetics of the EP2.7 in s smaller more room friendly size. Our new tweeter uses a Polyester diaphragm and offers much improved speed, detail and overall weight.
The innovation continues in the Bass range with our unique Aperture Bass Propagation Technology. This proprietary system is used for the custom Emerald 15" dipole woofer. This design increases low frequency power and linearity, while improving on the speed and articulation of the original CS2.7. The new Emerald designed 15" 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.
DSP equalization and active crossover functions are provided by the included Emerald Physics DSP2.4 Digital Processor and the included $600.00 upgraded passive Special Edition crossover uses custom Emerald Physics caps as well as many other upgraded parts & internal silver coated OCC wire.
