vinyl
laminate,
over five-eighths
inch
(0.625")
thick
MDF.
Multiple,

Dual ports
with 45" inlet
and flared, front
baffle outlet allow precise,
phase
accurate
woofer-to-port frequency
transition.
Ports also
aid in cooling

rubber woofer
trim ring allows consistent
po$rer response
characteristic at wide off-axis
angles. Flush-mount
tweeter plate and Alesis

Active logo/pilot
light plate also assure
smooth off-axis r,esponse.
Ul-approved fibergLass acoustical
darnping material damps intemal
mid-frequency
reflections from rear
of woofer cone before entering port,
lessening M distortion.
