Kenwood eXcelon P-XW1221SHP 12" Ported Subwoofer Enclosure 2000W Max 500W RMS

***This Item requires an additional 3-5 Days Handling Time***

The Kenwood eXcelon P-XW1221SHP is a preloaded 12" ported high-power subwoofer enclosure built for buyers who want stronger low-frequency output without having to source a separate woofer and box. It combines a single high-power 12" eXcelon subwoofer with a matched ported enclosure designed for harder-hitting bass, cleaner airflow, and practical fitment in common trunk and cargo-area installs.

For systems that need a straightforward bass upgrade with more output and higher RMS handling than basic loaded enclosures, the P-XW1221SHP gives you a ready-to-install solution using Kenwood’s matched high-power woofer-and-box design.
