Product Description
~Pioneer's TS-W2502D4 subwoofers are designed to produce powerful bass. Just take a look at the super-heavy-duty
construction, designed to handle up to 3,000 watts max. Double-stacked magnets deliver higher power, and a step-up
radial surround offers superior control and long excursions. Pioneer used a constructed cast-aluminum basket for this
sub--add in a patented IMPP cone and you've got a monster sub that can handle whatever you want to throw at it.

2. Pioneer Champion Series PRO Subwoofers
Powerful by Design
Champion Series PRO subwoofers deliver incredible
musicality heightened by booming bass--all in a versatile,
compact design. Inspired by Pioneer's strong SPL
heritage, Champion PRO subwoofers deliver a remarkably
powerful, accurate, and clear low-end that will transform
your in-car audio experience.
Air Suspension System
Boasting big bass power, the patented air suspension
technology of the Champion Series PRO subwoofer makes
it a hard-hitting performer. The innovative architecture of
the chamber creates a spring-like effect that compresses
air, enabling the speaker to fit a 10-inch enclosure while
delivering 12-inch bass sound.
Stealthy Installation
Masterfully engineered to deliver maximum sound in a
minimal enclosure space, the Champion Series PRO
subwoofer is designed to fit a variety of spaces. From
under the front seats and behind the back seats, to inside
doors and under the dash, your install can be customized
to fit your needs.
Built to Last
The Champion Series PRO subwoofer combines
innovative technology with top quality materials to
consistently deliver superior performance. This subwoofer
houses a three-layer, wide-roll, fiber-woven radial
surround that provides phenomenal power handling with
minimal distortion. The enduring strength of this
subwoofer comes from its aluminum die-cast chassis,
double stacked magnets, patented air suspension system,
and rigid lightweight IMPP cone.

3. TS-W2502D4 Features
Air Suspension System
For its revolutionary 3.25 inch deep Shallow Subwoofer, Pioneer created
an Air Suspension system effective within a 70% smaller-than-previous
enclosure that locks air for a spring-like effect between main and drive
cones moving in unison. The result is consistently clear, powerful,
wide-ranging bass response. The subwoofer's dual cone structure
maintains better sound linearity and reliability after hours of hard use
than conventional subwoofers with "spider" structures to keep the voice
coil aligned. This incredible technology is applied to this new generation
of high output, high performance subwoofers.
Double-Stack Magnet with Double-Stack Top Plate
To produce the tremendous magnetic energy we envisioned for this sub,
we employed double-stacked magnets, weighing a hefty 110oz, and a
double-stacked top plate above them. This design ensures positive,
powerful control of the voice coil during those long excursions--and it's
one reason you can ring up those high SPL numbers.
Wide-Roll 3-Layer Fiber Radial Surround
A sub's surround plays a key role in a speaker's performance. In order
for bass response to be clear and tight, the surround has to respond
evenly around its entire circumference without flexing or puckering,
even at high volume levels. That's why Pioneer created a surround
consisting of two layers of urethane with a layer of interwoven fiber
between them. It's strong, stable, and it reduces distortion. In addition,
the wider-than-normal design provides a long, linear excursion for
excellent control and heavy-duty durability.
Interlaced Basalt/Carbon Fiber Reinforced IMPP Cone
To ensure that you get more natural bass, Pioneer incorporated their
new Basalt fiber technology into their shallow subwoofers. The
volcanic-rock fibers create a cone that is lightweight, rigid, well damped,
stable in temperature extremes, and more . In short, this bass really
rocks.
Cast Aluminum Basket
Designed from scratch by Pioneer, this one-piece aluminum basket
assembly holds the motor assembly, cone, and magnet structure
securely in place. The benefits of this design: reduced internal stress,
superior damping, and increased magnetic efficiency.
Dual Voice Coil
The TS-W2502D2/D4 provides two voice coils, each either at dual 2 or
dual 4 ohms. So you can use a low-impedance amp to produce much Click images above to enlarge.
bigger, much more powerful bass. More options, more power: that's
what DVC is all about. The Bridging Adapter is included for an easy
Single Voice Coil hookup. It becomes a Single 4 Ohm or Single 8 Ohm
with Bridging Adapter for ultimate flexibility for use with modern mono
amplifiers
Add Newly Designed Spoke Grilles
We also recommend covering up your subwoofer with the UD-G308 .
This stylish spoke grille is a must add-on when building a system and
gives the look of pure professionalism.
