Pioneer TS-W261S4 10″ 4-ohm Champion Series Car Subwoofer
With the Pioneer TS-W261S4, engineers re-designed the spider assembly to allow the subwoofer to produce more accurate and rich bass. Taking notes from our high-end SPL competition and Reference Series speakers, the spider is now assembled onto the spider holder rather than directly on to the basket. Since the cone is also assembled onto the basket which can cause additional vibration, the independent structure of the spider holder helps minimize vibration coming from the cone. This improves playback response, sound outline, and provides high linearity.
Reinforced Cone Structure
Pioneer’s IMPP Composite Cone is newly re-designed to deliver a durable cone structure for accurate, yet powerful bass. The subwoofer now provides a single piece cone and drive cone, in addition to a lightweight and rigid dust cap. This combination offers more rigidity throughout the cone versus competitors in its class. An extremely durable, yet lightweight cone is vital to prevent cone failure at high sound pressure levels.
Single Piece Basket
The TS-W261S4 utilizes a highly rigid, fully-enclosed, single piece basket, derived from our world-record holding SPL competition subwoofers, to help minimize the vibration throughout the subwoofer and increase the driving force to the cone, producing louder and rhythmical bass. Improved stiffness of the basket provides for less sound leaks creating more clear and powerful bass.
Woofer: The Pioneer Champion series TS-W261S4 features an IMPP (Injection Molded Polypropylene) cone. This style of cone molding assures a uniform cone thickness for superior linearity and clarity. The cone is lightweight and rigid for low distortion and superior bass response.
Surround: The surround is made of dual-layer, fiber reinforced elastic polymer.
Terminals: The woofer’s spring compression binding post terminals are perfectly aligned for easy wiring. Each post will accept a pin connector, a single banana plug, or bare wire up to 10-gauge.
Double-stacked Magnet: The woofer uses double-stacked magnets to create a strong magnetic force. This increases the control exerted over the voice coil.
Sealed Box Volume: The sealed box volume is 0.8 ft³ (from 0.65 ft³ to 1.25 ft³ is acceptable).
Vented Box Volume: The recommended vented box volume is 1.1 ft³ by 3″ diameter x 5″ long port (0.9 ft³ to 1.5 ft³ is acceptable).
Single Reflex Bandpass Volume: The recommended bandpass box has a sealed chamber volume of 0.42 ft³ and a ported chamber volume of 2.6 ft³, with a slot port measuring 14-5/8″ x 5-7/8″ x 11-1/8″. Other designs keep the same sealed chamber size and the ported chamber changes to 2.3 ft³ with a 14-5/8″ x 9″ x 11-1/8″ slot port, or 3.0 ft³ with an 18-1/8″ x 3-5/8″ x 9-5/8″ slot port.
