What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Our take on the Pioneer TS-W310D4

by John Pollard

Add some boom to your daily drive

Is your vehicle's audio system sounding a little thin? Pioneer's Champion Series subs can remedy that situation, bringing out all the punch and power in your music by filling in the lowest frequencies of the sound spectrum. Throw one or two of these subs in your daily ride, power them up with a nice amp, and you'll understand what the fuss is all about — whatever you listen to, great bass will make it sound much, much better.

Built tough to give you solid bass

The TS-W310D4 12" subwoofer features a seamless IMPP cone that's injection-molded for exceptional precision and strength. A double-layered elastic polymer surround supports the woofer during cone excursion so you'll get right-on, hard-hitting bass notes even when the music's turned up loud. The dual 4-ohm voice coils allow you to wire the sub for 2- or 8-ohm impedance, so you get the flexibility you need when you add more Champion Series subs in the future.

Features

Woofer: The Pioneer Champion series TS-W310D4 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 elastic polymer.

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.

Specifications

Sealed Box Volume: The recommended sealed box volume is 1.25 ft³ (from 0.85 ft³ to 1.75 ft³ is acceptable).

Vented Box Volume: The recommended vented box volume is 1.5 ft³ with a 3" diameter x 6" long port (1.25 ft³ to 2.0 ft³ is acceptable).

Single Reflex Bandpass Volume: The bandpass box sizes recommended by Pioneer range from 0.7 ft³ per chamber to 1.1 ft³ per chamber; with an ideal size of 0.9 ft³ per chamber. One 3" diameter x 5" long port should be used in an enclosure with 0.9 ft³ chambers.
