Features

Woofer: The Pioneer Champion series TS-W259D4 features a seamless IMPP (Injection Molded Polypropylene) composite cone woofer. The surface area is approximately 14% larger than last year's model for louder and higher quality bass reproduction. This process 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.

Dual Voice Coils: For increased system flexibility, the woofer has two 4Ω voice coils. The two sets of spring compression binding post terminals are side-by-side for easy wiring. Each post will accept a pin connector, a single banana plug, or bare wire up to 10 gauge. The two voice coils can be wired in series to present an 8Ω load or in parallel to present a 2Ω load. Additionally, each coil can be connected to a different amplifier channel and each channel will see a 4Ω load.

Double-stacked Magnet: The TS-W259D4 uses Double-stacked High Energy magnets to create a powerful magnetic force. This increases the control exerted over the voice coil and the power transferred to the cone.
