model 2, 2sw-x

The Model 2 was the first commercial, full production Beveridge system. It is a full-range electrostatic speaker, employing the patented Beveridge acoustic lens system, driven by a built-in, Class A OTL tube power amplifier of high quality. It achieves a full 180 degree cylindrical-front waveform 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 Models 2 SW / SW-1 / SW-2, direct derivatives of Model 2, were aimed at increasing the speaker's total SPL. To that end, the main electrostatic transducer is relieved from reproducing the lowest octave. Two independent dynamic subwoofer enclosures cover the 30-70 Hz (sw) and 30-100 Hz (SW-1 / SW-2) range, crossed over by a built-in electronic network. The subwoofers are of the infinite baffle design. The electrostatic transducers continue to be housed in the Model 2-legacy, elegant cabinets, but the frontal sound slot is enlarged from 6" to 6.75", with a corresponding increase in throat width.

The Models 2 SW / SW-1 / SW-2's modified design of the acoustic lens takes advantage of the fact that the lowest fundamental octave is no longer reproduced by the electrostatic transducers. This allows the 2 SW-1 /SW-2 to achieve a total SPL increase of some 10 dB over the original Model 2. As with the earlier model, the SW / SW-1 /SW-2 electrostatic panels are driven by a built-in, Class A OTL tube power amplifier.

The subwoofers are driven by separate, solid state amplifiers (models 2 SW-1 / SW-2). An additional, external control module (CM-1) is added to the entire system (2 SW / 2 SW-1) and allows the listener a wide range of control over the system's reproduction characteristics (e.g., subwoofer integration, bass boost/cut, continuous stereo separation down to mono). The Models 2 SW / SW-1 / SW-2 produce a full 180 degree cylindrical-front waveform dispersion. As with all Beveridge speakers, the rear panel radiation is totally absorbed within the enclosure, eliminating any interference or cancellation by rear-generated waves.
