THE RAVEN L INE SOURCE (DESIGNED BY ORCA – MADE IN CALIFORNIA) IS THE ONLY TRANSDUCER OF ITS KIND.

The RAVEN LINE SOURCE is a very unique mid and high frequency drive unit; unique in what it does, and unique in the technical solutions involved to achieve that performance.

It is always a dilemma difficult to resolve for any speaker designers: where and how to cross over between the midrange and the high frequency drive units. No high frequency unit really does anything useful below a typical 2000 Hz or at the very best 1500 Hz, and most if not all midrange units cannot pretend to produce anything credible, and even less so when we talk about high end ambition, into frequencies higher than 5000 Hz or even 10000 Hz. So here it is, there is a need for two different drive units to cover that all so sensitive range, and that also means the necessity to use a crossover, with all the problems it brings relating to phase shift, level adjustment, matching dispersion patterns, etc… Great designers will come out of this but it is, no matter how we put it, one more compromise to handle as best as we can. Here we removed the dilemma and we open wide a new range of natural sound and dynamics. The RAVEN LINE SOURCE covers just by itself the huge range of 800 Hz to well over 40 KHz, and does it beautifully. We detail below how we came to that, but what is already important is to realize how uniquely harmonious will sound a speaker that is seamless on that all so crucial range.

RIBBON SURFACE AREA

The ribbon surface area is equal to that of a 71mm dome midrange (roughly 3in

in diameter) but with a mass that is 1/10 of a typical 25mm dome tweeter moving

mass. The benefit is extreme control for lowest possible distortion. The large

surface area allows the psychoacoustic critical 800 Hz to 8000 Hz frequency

band to be covered by a single driver to maintain coherency of phase, timber and

directivity. The net result is immediate: total ease and natural, altogether with

striking dynamics, not spectacular in itself, spectacular by its natural immediacy.

REAR AIR CHAMBER

The Raven Line Source has a 250 Hz resonance frequency

thanks to a very large rear air chamber that is 76mm deep by

63mm wide. The rear chamber is lined with 12 mm thick real

wool felt and filled with 50 mm thick Black Hole Stuff to

completely absorb the rear wave without reflections. The water

fall decay and impulse response are excellent!

MMX

The MMX material used is an aerospace metal matrix composite that has about 6

times the strength of pure aluminum. MMX has a much stronger centering force

to reduce distortion, increase power handling and improve durability. Here again

a combination of qualities never encountered into the same device, assembled

here by our design and thanks to rare and extarordinary modern materials.

FACE

The face is 9.3mm thick aircraft aluminum. All parts are assem-

bled with thick rubber gaskets to damp vibration - it is about as

dead as a solid block of granite.

TRANSFORMER

The transformer is internal with shortest possible leads to minimize inductance and

resistive loss. The transformer core is the best available for low loss, low leakage

and low distortion.

MAGNET TIPS

The neodymium magnet tips are designed to focus a

symmetrical and maximum strength magnetic field to minimize

distortion. The magnet tip is saturated at 1.2 Tesla for best

efficiency. Over such a large gap, this is a rare performance,

thanks to finely optimized magnet design.
