Features
This loudspeaker system delivers high
output, low distortion bass from two
18" Pro Rider woofers mounted in a
vented enclosure. It is designed for
portability and includes handles, metal
grille, reinforced corners, a durable
carpet exterior, casters and rubber feet.
A pole mount is included for support of
a high-pass enclosure. A remarkable
reduction in weight has been made
possible by using top-quality birch
plywood construction instead of the
usual composite wood materials, even
though power handling has been
increased.
