The S1 Loudspeaker
The S1 delivers absolutely everything, by adding almost nothing; its greatest strength is its well-constructed simplicity. It is a piece of fine furniture, designed to look as equally beautiful in your listening room as it sounds.
The S1 loudspeaker is a solid hardwood, hand-crafted 140 liter bass reflex design. Each pair is hand constructed from 100% kiln-dried hardwoods, in a variety of standard options or in a hardwood of your choosing. It is well braced, internally lined and damped to eliminate unwanted cabinet resonances, and port tuned to 30Hz for full, accurate bass response. The cabinet is acoustically isolated from its base and the floor, with solid brass risers.
The S1 minimally compensates for natural baffle diffraction, however it includes no additional internal components of any kind. No additional drivers are used, preserving perfect phase presentation throughout the frequency range. Because no multi-way crossover circuitry is necessary, your music isn't needlessly filtered, degraded or attenuated. The S1 simply holds the driver perfectly still at ear level, showcasing its remarkable performance free of any coloration, or distortion.
The S2 Loudspeaker
Like the S1, the construction quality and materials of the S2 are without compromise. The front baffles are constructed of 1.7 inch thick solid hardwood. To further eliminate distortion and resonance, the field coil driver is "magnet mounted" via the electromagnet housing to a 2.5 inch thick hardwood and glass-filled nylon support. This allows it to be all but entirely suspended in space, where it cannot transfer vibration to the front baffle.
The field coil driver has been modified for this design, leveraging the acoustic transparency of the driver suspension. It incorporates a novel, rear-firing whizzer which contributes to superb overall tonal balance and energy. As simply another part of the point source driver, the rear whizzer does not suffer from multi-way phase or timing issues. That benefit translates into a wonderful sense of live musical performance, with outstanding imaging and soundstage depth.
Below 130Hz, the Type D field coil is assisted by an Acoustic Elegance LO15 woofer for extremely accurate overall bass response. It is "port constrained" in the front, and employs an open, folded baffle design in the back. These design features lower free resonance, increase efficiency, and reduce wave cancellations for rich overall bass performance. Dual binding posts offer the option to run bridged passively, or to bi-amp for large listening spaces.
The PS1 Power Supply
The PS1 is a very tightly regulated, very low impedance power supply. It is specifically designed as a high noise rejection type, such that AC line noise and harmonic noise is not transferred to the DC regulated output powering the field coil. This unique feature damps any induced motor voice coil modulated signal from the field coil, shunting this AC induced audio signal at the power supply.
The result is "locked down" pure DC power to the driver, with no overlying AC audio signal.
The supply is adjustable from 9 to 12.5 volts, and can deliver constant DC current up to 2 amps. This allows the listener to significantly modify the "total Q" and overall character of a loudspeaker, and thereby tune it to their personal listening preference.
The rejection ratio of this regulated supply is over 70 dB. Input power is configurable to order, for 115 or 230 volt 50/60 Hz operation. Two 6-foot XLR cables are included as standard, however they can also be configured to your needs.
We are delighted that Whammerdyne Heavy Industries manufacturers these remarkable power supplies in a partnership with Songer Audio.
