The listening room is transformed as the speakers disappear and musicians come to life right in front of you.   A unique interpretation of the D‘Appolito Configuration, the EP-1 is a virtual full-range unit that plays effortlessly with minimal amplification. Based on theoretical work first proposed by Harry F. Olsen and Dr. Joseph D'Appolito and refined by Dr. Arthur Loesch, the EP-1 utilizes a first order series crossover made up of only a single inductor and a single capacitor. Series crossover topography means there are no parts directly in the signal path -- the crossover is shunted across the driver terminals, rather than in front of them. As a result, sound staging, dynamics, and transparency are unrivaled.   To further simplify setup, the series design also eliminates the need for bi-wiring and multi-amplification. Because the crossover network presents the amplifier with a constant voltage source, EP-1 Loudspeakers can be driven to high SPL levels with less than 10 watts of power, making them an excellent match for both the Model 301 and Model 302 power amplifiers.   All critical internal and external dimensions follow the mathematical principals of the Golden Ratio and the Fibonacci Sequence. By its nature, this neutralizes internal standing waves and minimizes external diffractions.   Finally, the drivers are physically time-aligned in the vertical axis, rather than flush-mounted on a tilt-back panel. This means that time-alignment is constant over the entire plane of the cones' surface and not limited to a single point in space.   Features Include: First order series crossover Custom matched and modified drivers for increased linearity 1" (25.5mm) thick High-Density MDF cabinets, harmonically damped with unique anti-resonance materials 2" (51mm) thick High-Density MDF woofer baffles Teflon® insulated .999% pure silver wiring WBT NextGen Ag Silver Binding Posts Isolated crossovers in external enclosures Adjustable tweeter control Duelund capacitors and resistors Integrated base Free analysis of your listening room for optimum placement.
