PHILOSOPHY
OF ACHIEVEMENT
Imagination. Product excellence. Sound systems that enhance the musical
experience. This is the essence of Dave Ellis's design philosophy since he built
his first pair of speakers nearly 25 yeas ago. The 1801! Series sound
reinforcement loudspeakers feature high efficiency, enormous output and
headroom, wide dynamic range, and very low distortion.
Naturally, each 1801
speaker is designed to fill your listening area with deep, dynamic, action-filled
bass and soaring lead guitars. Not to mention crystal clear vocals and all the
subtleties in the softest whispers. The 1801 Series consists of two stand
mounted monitor systems. Exquisite and refined, all precisely
voice-matched for a seamless soundfield and a truly exciting, three dimensional
listening experience.
Each 1801 Loudspeaker is
conceived as a cost-no-object high performance two way loudspeaker system
featuring high sensitivity, a detailed but romantic top end, smooth, natural,
articulate midrange, exceptional imaging, and an aggressive, dynamic low end.
These sound like the
design goals for virtually every midsized loudspeaker system; however, these
goals are rarely accomplished. First of all, transparency throughout the
midrange - the single most important element in high end reproduction - is
difficult to achieve with a woofer larger than six or seven inches; however,
bass response into the second octave at realistic listening levels requires
significant air to be moved, virtually ruling out small woofers of conventional
design.
Secondly, a transparent,
floating sound stage with precise image focus is almost impossible to achieve
with monopole loudspeaker systems of large dimensions, again ruling out larger
drivers.
Thirdly, to avoid upper
midrange deterioration due to tweeter break-up and crossover parasitics while
insuring midrange naturalness and image stability, a suitable crossover
frequency - above 2.5khz and uncomplicated crossover topology is required. This
rules out virtually all conventional woofers due to both power handling,
excursion limits and cone resonance.
The systems we present
here achieve our design goals by fully exploiting the remarkable capabilities of
two of the latest drivers from Norway and Denmark; the W18E001 Magnesium
woofer and the Hiquphon OWI tweeter, combined via a simple crossover network of
the highest quality.
