Designed for high power applications in PA
speaker mains, DJ touring speakers, sub-woofers and bass guitar systems
the new Rockville Bass Rider Subwoofers are a milestone in high-power
subwoofer design. The 15” woofers have an incredible power handling of
750 watts RMS/1500 watts peak. These “extra-long throw” woofers can
reach amazing sound pressure levels of 103dB with clean, deep bass down
to 20Hz that will rattle the walls of any venue!
Utilizing a new propriety mix of materials;
the cones are Kevlar®-impregnated making them stronger and tougher than
your average pro audio woofer cone. A newly designed “treated
asymmetrical-W shape surround” provides for superior excursion and
linear motion control.
The speaker connection terminals are high
quality nickel-plated screw style terminals and accept large gauge wire.
The terminals are attached to large diameter, high current tinsel leads
with silver solder to withstand high current and high temperatures
during long excursions.
The Rockville Bass Rider woofers’ voice coil
use a specially formulated, polyimide-insulated, high temperature wire,
designed especially for high SPL response. The winding is bonded onto an
incredibly durable and heat resistant aluminum composite former. The
voice coil winding length is an incredible 1”, which is 80% longer than
most standard pro woofers voice coils. The long coil dissipates heat
over a larger area and the increased length drives the cone to higher
excursions. The coil is layered with a tough thermoset clear epoxy for
added durability, abrasion and heat resistance.
The voice coil assembly is bonded to the
cone’s “double, linear-progressive Nomex spider”, using a thermoset
epoxy adhesive. The spider and surround are bonded to the frame with a
high strength cyanoacrylate adhesive, which is also used to bond the
dust cap to the cone.
The magnet motor structure is all new, and
designed with a back plate and pole piece which are forged from a single
massive block of low carbon steel. Utilizing an extended pole piece
beyond the front plate improves magnetic linearity and voice coil
cooling.
The yoke and washer plates are 10 mm thick for
extreme X-max and peak-to-peak excursions. With a narrow gap design and
a high “Y” factor strontium magnet, Rockville Bass Rider subwoofers
provide 75% more magnetic energy in the voice coil gap than typical pro
audio woofers.
And while your music might get hot, your
woofer will stay cool with a heat pump effect that’s built in via the
basket cooling system underneath the spider landing. The continuous flow
of air being circulated through the pole piece delivers cool air
directly to the voice coil. This integrated cooling system keeps the
woofer temperature under control, increasing power handling and of
course reliability.
The high-tinsel rolled steel frame is tough
and rigid which keeps the cone and magnet in perfect linear alignment.
In addition the frame has anti-vibration properties so there are no
external tones coming through the metal parts in to your music.
The result: a pro audio loudspeaker that is truly amazing. High SPL, extreme power handling, powerful and accurate bass output.
