The Raven R3.2MMX ribbon covers all midrange and treble above 800 Hz. This is the most critical range for imaging and intelligibility. Covering this entire frequency range with a single ribbon is important to a coherent presentation. The special MMX ribbon material is 6 times stronger than common aluminum so it is very robust and can play much louder without distortion.

Bass is produced by six 10 inch woofers that move a lot of air effortlessly with minimal distortion. For maximum dynamic speed the woofers exhibit exceptionally low mass and low inductance. The cones are made of a light weight cellulose coated on both sides with curvilinear profile.

To extract the best performance from the woofers we developed a new type of cabinet design. The woofer cabinet is a transmission line with progressive damping and exponential taper. It is a virtual acoustic black hole without resonance modes and no reflections. The proportions and damping design are considerably different from a conventional transmission line. The performance benefit is greater clarity, speed and detail. Resonance is so well controlled that the impedance is nearly flat making it a very easy load for a SET tube amplifier.

Like our award winning Ebb, the Menhir has a cardioid radiation pattern in the bass. A cardioid radiation pattern reduces room bass resonance and makes speaker placement much easier.

To optimize performance and get the best possible room acoustic integration we include a DEQX digital processor.
