About the EP 2.8
The Emerald Physics EP2.8 is a three-way, four-driver dynamic-dipole loudspeaker using two 15-inch carbon-fiber woofers, a 12-inch carbon-fiber midrange, and a concentrically mounted neo-polyester tweeter. It supports single-, bi-, or tri-amplified operation, with sensitivity rated at 97 dB in single- or bi-amped use and 100 dB when tri-amped. Its stated response is approximately 35 Hz–22 kHz without equalization; an optional DSP2.4/DSP2.8 processor or analog bass equalizer can extend the low-frequency response to approximately 20 Hz and optimize linearity. The EP2.8 uses Emerald Physics' dynamic-dipole and controlled-directivity design approach for an open, spacious presentation with reduced room interaction.
