A four piece speaker system represents the ultimate expression of the DeVore Fidelity Orangutan Series.

Offering an astonishing eight octave bandwidth with unprecedented flexibility and customization, the O/Reference can be installed in nearly any size room, and built to fit nearly any decor. O/Reference A has 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.
O/Reference A 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. 0.75” silk dome super-tweeter with a cast and 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 has 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/Reference system can be 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. ■
