The crossover network produces a 24dB-per-octave transition
at 700Hz between one 1501AL low-frequency driver and the
476Be high-frequency driver, allowing more precise control
over the system’s directivity pattern. With two woofers
assigned to the bass frequencies, the system’s speed, control
and power from the lowest to the highest frequencies are
unmatched.
Project Everest’s crossover network consists of four high-
quality low-loss boards – one optimized for each transducer –
separately mounted within the enclosure, to minimize potential
crosstalk. Together, they deliver exceptionally smooth system
impedance to the driving amplifier and permit the DD66000
to create an accurate, unencumbered three-dimensional sound
field with consistent acoustic characteristics at every listening
level.
The DD66000 system features separate low- and high-
frequency rear input terminals for bi-wiring/bi-amping and
front-mounted controls for low- and high-frequency trim,
woofer orientation and bi-amplification.
• The low-frequency level trim enables fine-tuning of mid-
bass and midrange output levels with no series loss, to
compensate for varying room characteristics.
• The high-frequency level trim adjusts attenuation to the
476Be driver in three steps from –0.5dB to +0.5dB.
• The woofer orientation switch configures system pairs to
operate as either left or right speakers for proper imaging.
