A sophisticated 1.25” textile dome with an oversized magnet (3 times
larger than standard) details the midrange. A compact ribbon with 3/8”
apertures and a Samarium Cobalt magnet articulates up to 30 kHz.
A rear firing 1” titanium dome ambience driver (defeatable via switch 4) is
used to enhance treble distortion. This driver allows the sound staging and
“air” of a dipolar response without the ragged midrange anomalies and
cancellation effects.
An additional advantage of the rear tweeter is the preservation of depth.
An inherent limitation of the stereo process dictates that depth is largely
determined by amplitude differences; i.e. the louder the source, the closer
it can appear. This can cause a saxophone player, for example, to jump
forward every time he emphasizes a note. This occasionally makes even
accurate speakers feel aggressive. The rear tweeter helps to stabilize the
soundstage by establishing a balance between the front and rear output,
resulting in more uniform power distribution.
