About the Pioneer TS-W309D4
Your favorite song is playing, you pull up at a stoplight, and pretty soon you've got the urge to launch an all-out drum solo on your dash — we've all been there. Maybe your drum set is imaginary, but you want the bass in your ride to be real as it gets. And that's where Pioneer's Champion Series subs come in.
Large cone for bigger bass
The TS-W309D4 12" subwoofer features a seamless, injection-molded polypropylene cone that's about 14% larger than last year's model for extended bass response. The oversized, glossy cone features the classic Pioneer logo underscored with eye-catching red script, giving this sub the unmistakable mark of a Champion. A double layered elastic polymer surround supports the woofer during cone excursion so you'll get hard-hitting bass.
Dual voice coils
The dual 4-ohm voice coils allow you to wire the sub for 2- or 8-ohm impedance, so you get the wiring flexibility you need when you add more Champion Series subs in the future. A solidly built motor assembly uses a double magnet design to drive the cone hard for accurate, soul-shaking beats. So the next time you pick up those invisible drum sticks, you'll have this sub to back you up with loads of energetic, dynamic bass.

Features
Woofer: The Pioneer Champion series TS-W309S4 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-W309S4 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 sealed box sizes recommended by Pioneer range from 0.85 ft³ to 1.75 ft³; within this range the ideal size is 1.25 ft³.
