This 12' Champion Series subwoofer is built for max impact: a 3,500 W peak (1,000 W nominal) rating and a durable interlaced basalt\/carbon reinforced IMPP cone promise strong transient response and controlled motion. In this review the single biggest reason to buy is its ability to deliver room-filling low end from a compact enclosure volume, making it a straightforward upgrade for sound systems that need deeper, tighter bass.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eHigh power handling:\u003c\/strong\u003e The 1,000 W nominal power rating and 3,500 W max give the subwoofer headroom to reproduce heavy bass passages without clipping when paired with a capable amp.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eDual 4 ohm DVC:\u003c\/strong\u003e The dual voice coils allow flexible wiring options for matching impedance to a wide range of amplifiers for optimal power transfer.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eReinforced cone:\u003c\/strong\u003e The interlaced basalt and carbon fiber reinforced IMPP cone improves rigidity for accurate mid-bass and reduced distortion under high excursion.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eWide frequency response:\u003c\/strong\u003e With a 20 Hz to 150 Hz range the speaker covers deep subbass as well as upper bass for tighter integration with midrange drivers.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eRobust motor assembly:\u003c\/strong\u003e The double-stack magnet and top plate provide a strong magnetic field that supports high output and reliable excursion control.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eInstallation-friendly size:\u003c\/strong\u003e The 7-1\/2' mounting depth and 11' cut-out make it compatible with many sealed and ported enclosures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Pioneer TSW312D4 is ideal for car audio enthusiasts who want powerful, authoritative bass from a single 12' driver and who can pair it with an amplifier capable of delivering near its nominal power.
