With ideal sound reproduction and mechanical behaviour
across more than seven octaves from 200 Hz to 18 kHz, the
Gryphon Pendragon ribbon eliminates multiple crossover fil-
ter sections in the critical mid frequency range, preserving
spectral and temporal integrity.
The 200 Hz crossover consists of the finest Duelund parts and
solid silver components encased in a heavily damped alumi-
nium block suspended freely behind the panels. At the ex-
treme high frequency transition between the ribbon and the
AMT super-tweeter array, the ribbon rolls off naturally with no
lowpass filter section in the signal path.
The high frequency system’s innate wide and even horizontal
dispersion with virtually nil vertical dispersion creates a large,
stable sweet spot with none of the floor and ceiling reflections
that muddy the sound of conventional multi-way systems. Eli-
minating this major source of interference allows Gryphon
Pendragon to achieve new levels of room-independent clarity
and resolution.
Bass Foundation
Significant effort and resources have been focused on delive-
ring extended deep bass with articulation, force and authority,
completely independent of the acoustic environment.
To keep pace with the extraordinary speed and openness of
the dipolar drivers with none of the discontinuity that plagues
more conventional “hybrid” speakers, the Pendragon bass
tower offers elegantly simple, original Gryphon solutions to a
number of complicated problems.
Deep bass is, perhaps counter-intuitively, the most difficult
part of the audio spectrum to reproduce with both accuracy
and seamless integration with the upper frequency range. A
full-range speaker with bass drivers built into the main enclo-
sure has its own set of demons to exorcise as does the cur-
rently popular approach of tacking on a so-called “subwoofer”
for bottom end duties.
Each Pendragon bass tower houses eight custom designed 8”
drive units and a built-in, specially designed Gryphon Class
A/B power amplifier capable of 1,000 Watts continuous output.
For extended headroom, available peak power is approxima-
tely 4,000 Watts or 4.5 horsepower.
Unlike compromised, “universal” amplifiers, the Pendragon
bass amp has been conceived and built exclusively for opti-
mal integration with the system’s custom-built drive units,
rigid cabinet and flexible, user-adjustable room integration
controls, for a level of performance unachievable by any stan-
dard mix-and-match approach.
