Vibration Attenuation (Damping) Comparison

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.

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.

Carbon Fiber IMPP Cone

TS-W8102SPL TS-W5102SPL

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.

Woven Aramid Fiber Radial Surround

TS-W8102SPL TS-W5102SPL TS-W3002D4 TS-W2502D4

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. 45
