Bass that hits hard and sounds great

Pioneer's Stage 4 Reference Series subwoofers add premium bass to your system — you'll hear accurate, lifelike low end that hits like a ton of bricks. Pioneer loads this bass powerhouse with a wide array of advanced features and technologies to make sure you get the most out of your music.

The right cone for the job

A stiff woofer cone is optimal for moving air to create powerful bass, but a cone that's too heavy loses control and introduces distortion into your music. Pioneer utilizes the properties of different materials to create a cone that provides reliable stiffness, yet is light enough to respond to rapid changes in your music. The cone features an Aramid fiber surface layer, a polypropylene core, and a glass fiber reinforcement layer — all three work in tandem to pump out great bass that's not dragged down by excess baggage.

Pioneer also primes their Stage 4 subs with a patented suspension system which utilizes progressive flexing to keep the cone perfectly centered during heavy play. A butyl-coated fiber surround also promotes the deep excursion that you need for strong performance.

Authoritative and accurate

The TS-W252PRS 10" subwoofer handles up to 400 watts RMS for high-impact bass. A die-cast aluminum frame adds strength and gives the sub stability over the long haul. Pioneer recommends using this sub in a sealed enclosure for accurate, powerful performance.
