Pioneer.eu: Pioneer has introduced its new line-up of Champion Series car subwoofers, combining high power output, clean and punchy bass and sharp new cosmetic design. They use technologies derived from our world record-breaking SPL and Competition-grade models.
New models include the 30 cm TS-W309, TS-W309S4, TS-W309D4 and the 25 cm TS-W259S4 and TS-W259D4, in shops as of mid January 2011. Available in single 4-Ohm and dual 4-Ohm, the subwoofers offer greater installation flexibility.
Each new model features a seamless composite IMPP woofer cone that has been enlarged by 14% to generate greater air movement. Together with an improved magnet structure, air vents in the basket under the spider and holes in the aluminium former that both work to reduce the mechanical resistance, this combination of innovations results in smooth response and clean, solid bass sound.
The subwoofers’ surround is constructed of a sophisticated dual-layer elastic polymer that is much lighter than rubber, decreasing the weight of the moving parts to improve control and speed, whilst guaranteeing high durability.
Additional performance features across the range include:
- Integrated one-sided terminals: to allow for greater flexibility and easy installation, all Champion Series speaker terminals have been placed on one side of the subwoofer rather than both sides like conventional subwoofers.
- Cupper wire voice coil with aluminium former: the aluminium used for the former improves heat radiation which eliminates the need for a heavy voice coil, decreasing its weight by 7%. In addition, the holes in the former reduce distortion.
