Advanced SPL Subwoofers from Pioneer Provide More Punch, Power and Extension

New Speaker Technologies Make Pioneer Premier SPL Subwoofers Virtually Indestructible

New technology from Pioneer Electronics (USA) Inc. adds power to its new line of Premier sound pressure level (SPL) subwoofers, which now can produce bass with more punch and extension. Consumers and competitors alike demand more output from their subwoofers. By applying breakthrough speaker technologies that include titanium voice coil, ceramic voice coil wire, double cone design, aluminum heat sink and extended excursion, Pioneer is delivering the sound pressure level they demand.

“Pioneer takes pride in its speaker heritage and as a company, we will continue to push the envelope in speaker technology,” said Michael Townsen, vice president of marketing for mobile entertainment at Pioneer Electronics (USA) Inc. “The new Premier SPL subwoofers highlight new technologies expected only from high dollar speakers. Pioneer brings these technologies down to affordable levels so more of our consumers will be able to appreciate them. The new subwoofers are testimony to how subwoofers should be built.”

Pioneer Premier TS-W3004SPL 12-inch and TS-W2504SPL 10-inch subwoofers were designed to withstand the output of high-powered systems. Mono digital amplifiers can produce massive output power that many conventional speakers fail to endure. Pioneer's internal components, “the engine” of the subwoofer, such as the titanium voice coil, ceramic voice coil wire and aluminum heat sink were engineered to resist as well as quickly dissipate heat, even with excessive input power. Moving parts, such as the interlaced carbon fiber/glass fiber reinforced IMPP cone and wide roll three-layer fiber radial surround were intended to improve output with the least amount of distortion. Because the intention for these subwoofers is for competitive use, Pioneer took careful consideration of each subwoofer part; such as cone structure, voice coil, suspension and motor structure, all of which can make a difference in SPL competitions.

The Pioneer Premier TS-W3004SPL and TS-W2004SPL offer the following benefits:

  • Double Cone Structure (patent-pending) - A massive contact area between the two cones virtually eliminates the dust cap failure of typical subwoofer designs especially in extreme SPL conditions.
  • Interlaced Carbon Fiber/Glass Fiber Reinforced IMPP Cone (patent-pending) – This material forms an incredibly resilient fiber weave, providing strength and rigidity for the cone.
  • Double Cone Reinforcement Nodes (patent-pending) - Derived from Pioneer's TS-SW124D shallow subwoofer, these patent-pending reinforcement nodes securely connect the two cones and further develop the stability and resiliency needed for high SPL performance.
  • Ceramic Coated Voice Coil Wire (patent-pending) – This material provides superior heat capability to more than double the input power handling capability. Ceramic coating insulates the voice coil wire, preventing short circuits due to overheating and dramatically improving reliability.
  • Aluminum Heatsink Cooling System – This cooling system draws heat away from the inside of the subwoofer, improving heat dissipation by 20 percent and reducing temperatures significantly.
  • Titanium Voice Coil Bobbin – Titanium is used for its strength and lightweight nature, providing 1.5 times more strength than conventional designs.
  • Wide Roll, 3-Layer Fiber Radial Surround (patented design) - Honeycomb-pattern reinforcing cotton cloth sandwiched between a wide-roll, dual-layer urethane surround resists surround puckering at large excursion, resulting in louder, more controlled bass response.
  • Super aramid fiber Damper – The tear-proof damper withstands the most potent abuse.
  • Double-Stack Magnet – The new design increases BL (force factor) 6~8% for tighter, more controlled bass performance.
  • Die-Cast Bottom-Hold Aluminum Basket – A massive die-cast basket cradles the top & bottom side of motor structure securely, effectively minimizing vibration and undesired output loss.

Pioneer Premier subwoofers will be available in dual 4-Ohm and 2-Ohm versions for maximum installation flexibility. The TS-W3004SPL can be installed in subwoofer enclosures between 0.85 ~ 1.75 cubic feet and the TS-W2004SPL between 0.65 ~ 1.25 cubic feet. Pricing and availability will be announced at the Consumer Electronics Show in January 2005.
