Microscopic Cross Section View
For its revolutionary 3.25-inch-deep 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.

Although aluminum die-cast baskets have been around for many years, not all are
created equal. Whereas other manufacturers purchase off-the-shelf designs, Pioneer’s
baskets were designed in-house, from scratch. Die-cast baskets also provide excellent
damping characteristics, to attenuate vibration quickly and prevent distortion.
Unlike other manufacturers’ designs, Pioneer’s basket cradles the bottom plate
and motor assembly. During high SPL levels there is a tremendous amount of pressure
placed on the motor assembly.
By supporting (cradling) the motor
assembly any unwanted flexing or
vibrations which can lead to energy
loss are prevented.

Vibration Attenuation (Damping) Comparison
Improved Chassis Rigidness
Preventing cone failure at high pressure levels requires an extremely rigid yet lightweight
cone. So Pioneer developed a patent-pending IMPP cone using a proprietary composite
blend of long carbon fibers and injection molded polypropylene. These materials were
chosen for their extraordinary strength and lightweight characteristics. The long carbon
fibers interlace together to form an incredibly resilient fiber weave, providing strength
and rigidity for powerful bass.
The TS-W8102SPL, TS-W5102SPL, TS-W3002D4 and TS-W2502D4 incorporate a
patent-pending Woven Aramid Fiber Radial Surround which improves power
handling and reduces distortion. Similar to a radial tire, the surround is constructed
of three layers—two consisting of rubber and one of interwoven aramid fiber.
The aramid fiber layer is designed with a “honeycomb” weave, which evenly
distributes strength throughout the surround material, eliminating any weak
points of surround and improving high-power capability. The result is an
extremely durable and resilient surround that resists “puckering” (distortion
often produced under extreme power conditions).
Benefits of Woven Aramid Fiber Radial Surround
•
Improved power handling capability
•
Reduced distortion (anti-puckering design)
•
Improved linear excursion
•
Louder, more accurate bass
The three layers are formed under a high-pressure, high-temperature
process. The result: an extremely durable and high-performance surround.

Caution: To avoid damaging your amplifier/subwoofer system, please make sure that the continuous power output of the amplifier is lower than the nominal power handling of the subwoofer.
