Description:
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 18”
woofers have an incredible power handling of 900 watts RMS/1800 watts
peak. These “extra-long throw” woofers can reach amazing sound pressure
levels of 105dB 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.
