The upgraded version of the highly regarded EP 4.7, these EP 4.8 speakers are clear, precise and deliver an incredible amount of detail. Custom designed Emerald Physics Carbon Fiber Series 15 woofer and 12 midrange driver with tweeter positioned in the center provide increased speed, transparency and resolution while eliminating midrange smear completely. These are a must hear for anyone in the audiophile community! Information from the manufacturer: 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 15s 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 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. The lower bass woofer is a 15 inch carbon fiber woofer The upper midrange is a 12 inch carbon fiber driver with a center firing tweeter They measure 39 inches tall, 22 wide and 21 inches deep This pair is in impeccable cosmetic condition, fully functional and include the original shipping boxes. The set is complete with the factory external crossovers and Emerald Physics Bass Optimization Module (BOM). The BOM was an optional $500 upgrade during initial purchase. See my feedback and buy with confidence! IMPORTANT PLEASE READ: *Due to size of the speakers and boxes, please anticipate 30 day shipping Please review all photos and description prior to purchasing and reach out if you have any questions.

For Sale: Emerald Physics CS2 open baffle speakers. Requires 4 channels of amplification (or you can custom design a crossover)The stock Behringer DCX2496, that served as the active crossover, was replaced with a (much better) standard MiniDSP 2x4 unit. Understandably, Emerald Physics supplied their newer, next gen CS2.3 speakers with a MiniDSP unit rather than the noisy Behringer DCX2496 active crossover.The speakers themselves look very clean with zero issues. The Minidsp serves as the active crossover (currently set to 1khz LR48 High Pass / Low Pass) and can import a REW Room Correction data file into its room correction feature (something the Behringer DCX2496 could not do). The MiniDSP program file will be provided with sale.The reviews on these speaker were very positive - with many calling them Quads on SteroidsPickup in west sub of Chicago only....to big/heavy to ship, but I have the original CS2 boxes (a bit ratty)...Specs & Original PricingType: Bi-amplified stereo speaker system with electronic crossover (amplifiers not included, bi-amplification required)Drivers: Two 15? woofers in open baffle, dipole operation; 1? compression driver forward radiator, conical waveguideCrossover: 1000Hz, 48dB/octave slopes (digital signal processing crossover)Frequency response: 20Hz–22kHz, -3 dB down pointsSensitivity: 100dB/2.83 vDimensions: 48? x 18.5? x 6?
