The
D4 has a wider dispersion than the larger models. The high performance
D4 is a true coaxial loudspeaker with a real compression driver
concentrically arranged so that the upper frequencies emerge through the
center of the low-frequency driver’s magnetic structure and cone via a
precisely tapered Tru-Phase™ high-frequency waveguide. This special
construction provides consistent, wide dispersion up to 16 kHz, all but
eliminating high-frequency narrowing. Further pattern improvement is
achieved by precisely mounting the low frequency driver (and its
concentric HF driver) centered in the baffle, as contrasted to the
offset designs used by others.
The D SERIES offers powerful
magnetic structures and efficient coils to ensure high output, which
results in more headroom per power amplifier. Each D SERIES ceiling
model includes everything needed for standard installations, and has a
built-in autoformer allowing it to be used in 8-ohm or 70V/100V
applications. The D SERIES ceiling loudspeakers are ETL listed and all
models have been tested by ETL to comply with UL1480, UL2043 and
CSA60065.
