ENCLOSURE
MATERIALS AND CONSTRUCTION
Front baffle painted in metallic charcoal-gray, one inch (1”) thick MDF with
radiused edges to minimize diffraction. Sides and rear baffle covered in
metallic charcoal-gray vinyl laminate, over five-eighths inch (0.625”) thick
MDF.
Dual ports with 45° inlet and flared front baffle outlet allow precise, phase
accurate woofer-to-port frequency transition. Ports also aid in cooling
internally mounted primary amplifier heat sink.
Flush mount, rubber woofer trim ring allows consistent power response
characteristic at wide off-axis angles. Flush-mount tweeter plate assures
smooth off-axis response.
UL-approved fiberglass acoustical damping material damps internal mid-
frequency reflections from rear of woofer cone before entering port, lessening
IM distortion.
TRANSDUCERS
L
OW FREQUENCY DRIVER:
6.5” (165mm) diameter dynamic driver with proprietary non-woven carbon
fiber (NWCF) cone and 1.5” diameter, long-wind voice coil.
Dampened linear rubber surround with moderate internal damping and
constant linear displacement Nomex spider. ±5 mm X-max excursion
capability.
Dual magnet structure uses top magnet in opposed (“bucking”) configuration
for magnetic shielding.
HIGH FREQUENCY DRIVER:
1” silk soft-dome tweeter with special wave guide baffle.
Low-viscosity ferrofluid cooling extends power handling while retaining
impulse response capability.
Dual magnet structure uses top magnet in opposed (“bucking”) configuration
for magnetic shielding.
