THE O/Ref 3

The O/Reference system scaled down to three pieces, utilizing the same main speakers and a single Bassmachine summed to mono for the lowest octave.


O/Reference A

10” paper-cone woofer with a cast Bronze chassis and an all new woofer motor, fully optimized with a pure AlNiCo magnet, copper Faraday rings above and below the gap, a titanium former, and a machined bronze phase plug resulting in better magnetic and inductive linearity, increased sensitivity, and an order of magnitude lower distortion throughout most of the frequency range.

1” silk dome tweeter loaded by a cast & machined Bronze horn with an all new tweeter motor utilizing a large rare-earth magnet and an underhung voice-coil for increased linearity at lower treble frequencies and higher sensitivity.

.75” silk dome super-tweeter with a cast & machined bronze horn and rare-earth magnet.

Solid machined Bronze port tubes and machined brass input-plate are de-coupled from the cabinet to reduce vibration.


O/Reference B

11-inch reinforced aluminum woofer and all-new motor system capable of a massive 2 1/4 inch excursion.

11-inch reinforced aluminum passive radiator naturally tuned below 20Hz in-cabinet with no equalization.

Rigid two-inch thick birch plywood front baffle and solid machined brass input-plate to reduce vibration.

Dedicated 700 watt amplifier and all analog signal path including fully adjustable low-pass crossover, variable phase, subsonic filter, and equalization at 20Hz and 35Hz to tailor response to different room installations.


THE O/Ref 3

The O/Reference system scaled down to three pieces, utilizing the same main speakers and a single Bassmachine. While there are clear benefits to using two Bassmachines as in the O/Reference system, including ambience retrieval, low bass dynamic impact, and easier room response optimization, there is no question that the lowest octave has the narrowest cost/performance benefit: it is very expensive to reproduce the bottom octave with the highest fidelity. By using a single Bassmachine and summing the left and right information of the lowest octave to mono, significant cost savings are gained in a system that still achieves a very high measure of the O/Reference performance.
