Features & Specifications



Pioneer TS-A301S4 12″ – 1600 W Single 4 Ohm Champion Series – Component Subwoofer

The TS-A301S4 Champion Series subwoofers have evolved from Pioneer’s award winning “SPL Champion Edition” lineup, known for its deep and powerful bass production. The TS-A301S4 12” single-voice coil component subwoofer features a re-designed large and powerful motor assembly for improved efficiency and sensitivity. The subwoofers basket are optimized using a reinforced structure design for added strength and reduced vibration to deliver excellent sound quality. This subwoofer has continuous power of 500 watts with a maximum peak of 1,600 watts. It features an advanced 2-piece durable Honeycomb IMPP™ composite cone structure plus a rigid drive cone to deliver high output levels with reduced distortion.

Rolling in the deep

Pioneer’s Champion Series subwoofers are made to give you the deep, powerful lows you expect from Pioneer. The TS-A301S4 12″ subwoofer handles up to 500 watts RMS RMS and features an injection-molded polypropylene cone that’s impregnated with glass fibers and mica for exceptional precision and strength. An elastic polymer/reinforced fiber surround supports the woofer during cone excursion to give you accurate, hard-hitting bass notes when the music’s hot.

Dishing it out

This potent Pioneer sub will bring out all the power in your music by filling in the lowest frequencies of the sound spectrum. Its 4-ohm impedance makes it a great match for bridged amplifiers. When you’re looking for great bass, the TS-A301S4 is ready to dish it out.

Champion Series

The Pioneer Champion Series Subwoofers deliver powerful bass from their 12” subwoofers. These subwoofers are offered in either a dual or single 4-Ohm voice coil design with the ability to handle high power input at higher volume without compromising sound quality.

Iconic Champion Series Cosmetics

TS-A301S4 Features

Woofer Cone: Pioneer uses an IMPP (Injection Molded Polypropylene) woofer cone. This process of cone molding assures a uniform cone thickness for superior linearity and clarity.

Terminals: The spring post terminals will accept pin connectors, single banana plugs, or bare wire up to 10 gauge.

Sealed Box Volume: Pioneer recommends a sealed enclosure with an internal volume between 0.85 ft³ and 1.75 ft³, with an ideal volume of 1.25 ft³. Sealed enclosures provide the most control over the woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.

Ported Box Volume: The recommended ported box volume ranges from 1.25 ft³ to 2.0 ft³, with the ideal size being 1.5 ft³, using a single 3″ diameter x 6½” long port. Ported (or vented) enclosures typically provide better overall efficiency than sealed, maximizing bass output for a given amplifier.

Free-Air: The woofer can also be mounted in free air to a baffle board (infinite baffle, no enclosure). When mounted in free air, the power handling is reduced by 75% (to 125 watts).
