model 5

The smallest model in the Beveridge line borrows its name from its height - five feet tall. It is a semi full-range electrostatic speaker employing the Beveridge acoustic lens system. Resembling the Model 3 on a smaller scale, the 5 is a passive speaker, allowing the user the choice of his own amplification. The Model 5 is the only speaker in the Beveridge line to employ a single electrostatic element, a 3' x 1' transducer (all other models employ two or three transducers, of various dimensions, per cabinet). It is also the first to employ a circuit board transducer type, like the subsequent Model 6.

The cylindrical-front waveform is created by means of a modified acoustic lens, coupled with the vertical narrow line source at the front, yielding a maximum 90 degree, cylindrical-wave dispersion. As with all Beveridge speakers, the ES panel's rear radiation is totally absorbed within the enclosure, eliminating any interference or cancellation by rear-generated waves.

The Model 5's 12" woofer, housed in the main column (a 24" tall x 18" diameter, cylindrical chamber), covers the low audio range (30 - 250 Hz). A built in, bypassable cross-over network allows for a variety of bi-amplification modes, but the ES unit is protected at all times by a fixed, non-passable high quality capacitor.
