Kenwood Excelon P-XW1221SHP

12" Ported Subwoofer Enclosure

The rugged enclosure is built from 5/8" MDF with a 3/4" thick internal baffle to give the sub solid support. The box's slant-back design suppresses standing waves which can interfere with bass response, and allows it to fit neatly behind the rear seat of an SUV. Rounded port corners reduce port noise and airflow resistance. The P-XW1221SHP can be used in front-facing, rear-facing, or down-firing applications. Steel-mesh grilles protect the speakers from accidental damage. This box handles up to 500 watts RMS, so you'll want an amplifier with the power to get the best from this enclosure.

Driver: The Kenwood Excelon P-XW1221S ported subwoofer enclosure features a single heavy-duty 2?, 12" driver that can handle 500W RMS with peak power up to 2000W. The injection-molded Polypropylene cone features a dual area cap that provides the rigidity needed for high-power handing while delivering accurate bass. Other improvements include a computer-optimized spider, for increased mechanical durability and stress control, along with a robust thermal management system. This includes a closed yoke design with an aluminum bobbin for advanced airflow control and heat dispersion around the voice coil and spider. The 12" subwoofer driver is protected with a steel mesh grille.

Enclosure: The P-XW1221S is constructed of 5/8" thick MDF (Medium Density Fiberboard) with a 3/4" thick baffle, providing outstanding strength and durability for maintaining tight accurate bass at high volumes.

  • Slant Back Design: The enclosure's slant back design allows it to fit behind vehicle seats easier, and helps suppress standing waves from forming inside the enclosure.
  • Multi-Position Mounting: The enclosure is designed so that it can be mounted in a forward, rearward, or down-firing orientation. Raised "legs" on the speaker side of the enclosure allow it to sit in a down-firing position. This ensures low frequency transmission without loss, while helping protect the 12" driver.
  • Improved Port: The enclosure's port opening features rounded edges for reduced airflow resistance and less generated noise.

Connection: The P-XW1221S includes a single pair of nickel-plated spring-post connectors that can accept speaker wire up to 8AWG.
