Our take on the W8T4S4

The Rockville W8T4S4 is an 8-inch shallow-mount car subwoofer built for tight spaces like under or behind a truck seat. It handles 400 watts RMS and 800 watts peak with a single 4-ohm voice coil. Its shallow depth sets it apart from standard subs, but it won't match the output of a full-size sub. Owners say it delivers solid bass for the money, though some find it lacks deep extension.

About the W8T4S4

The Rockville W8T4-S4 is an 8-inch shallow-mount subwoofer with a 4-ohm single voice coil. It has a very thin mounting depth, so it fits installations where standard-size subwoofers can't. Suggested spots include behind the seat in a compact car or pick-up truck, or in a motorcycle's saddlebags.

The motor uses a "High-BL" structure with a large-diameter, progressive-roll spider, which increases linearity and improves overall sound quality. A vented core magnet motor structure with extra-thick back and top plates allows full voice-coil excursion, peak to peak. The power ratings are CEA compliant.
