The Beveridge loudspeakers
are full range electrostatic systems. Depending on model, some may include dynamic subwoofers, incorporated
either in the main enclosure or in separate satellite cabinets (commodes). Similarly, the
range includes both active and passive models. The active systems are driven by their own
high quality OTL tube amplifiers and, in the case of Model II-SW1 and Model
2-SW2, the separate
subwoofers are driven by their own dedicated, solid-state, power amplifiers.
The earlier SW1 employed a separate CM unit that allowed user control over a wide range of parameters, such as wave dispertion
control, channel separation and subwoofers/main speaker crossover.
The passive Beveridge models that employ subwoofers can be bi-amped in a variety of
ways either through, or by-passing, the internal crossover network. The ES units however,
are internally protected at all times by a high quality capacitor.
All Beveridge electrostatic speakers employ the unique lens system mounted
internally in front of the ES panel which controls and augments the wave dispersion pattern.
The main ES transducers are a true vertical line source that covers, depending on model,
at least six octaves, up to and beyond 15KHz (+/- 2db). They are capable of reproducing
realistic sound levels of full orchestral ensembles with a clarity, coherence and sound
stage imaging which earned them the majestic and legendary status they deservedly enjoy.
The Beveridge Audio Systems faithfully reproduce the sound stage of any original
location, be it large cathedrals, concert halls or intimate, small chamber
venues. The cylindrical
waveform delivers true 180o, full range, phase coherent sound dispersion
throught, and anywhere, within the listening environment.
To this day the Beveridge Audio Systems are the paradigm by which
all other sound
transducers are appraised. |
