Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Woofer: The Pioneer Champion series TS-W260D4 features a
seamless IMPP (Injection Molded Polypropylene) composite cone. 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
Dual 4-ohm Voice Coils: This woofer features two 4-ohm voice
coils that offer wiring flexibility. When the voice coils are wired in parallel,
the woofer presents a 2-ohm load. When the voice coils are wired in series, the
woofer presents an 8-ohm load.
Terminals: Both sets of the woofer's 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 8 gauge.
Double-stacked Magnet: The woofer 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.
Sealed Box Volume: The recommended 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 with a 3" diameter x 7.5" long port (0.9 ft³ to 1.5 ft³ is acceptable).
Single Reflex Bandpass Volume: The bandpass box sizes recommended
by Pioneer range from 0.45 ft³ per chamber to 0.8 ft³ per chamber; with an ideal size
of 0.6 ft³ per chamber. One 3" diameter x 6" long port should be used in an
enclosure with 0.6 ft³ chambers.
