The 3XL range of subwoofers is innovative
in that it is designed to work with the new
generation Class "D" amplifiers. Class "D"
amplifiers heat up the woofers voice coil
two to three times hotter and faster than a
conventional class A/B amplifier. This calls
for Xtreme measures and special parts to
classify these as a true "Class D Subwoofer."
But hey, this is PowerBass. We have it
under control.
First, we use industrial assembly glues that
handle this excessive heat that would
normally tear a conventional speaker apart.
Then there is perimeter venting to allow air
movement over the voice coil built into our
custom CNC cut, cast aluminum basket.
The basket works as a strong support for the
moving mass of the proprietary non-pressed
paper cone body that holds the zirconium-
coated poly truss cone that displays the
raised PBX logo.
The 3XL woofers all feature 3" HD BASV
voice coil formers that are anodized black to
help dissipate heat. To allow full movement
of the cone, we utilize an ultra high roll
treated foam surround that increases the
cone area for higher output along with
linear cone stability throughout the
subwoofers 3" of linear travel.
To make sure high voltages from the
amplifier reach the speaker, we use
Pro-Lock terminals and Xtra large motor
assemblies to handle the high power these
speakers are designed for.
3XL woofers are available in 10", 12", and
15" sizes, feature dual 1-ohm voice coils,
and are designed to work best in ported
enclosures for maximum SPL output.
