Rockville W10T4-S2 10in Shallow Mount Subwoofer - Compact Deep Bass

Our review of the Rockville W10T4-S2 finds a compact 10in shallow mount subwoofer that delivers surprising low-end impact for cramped installs. Designed for trucks, tight enclosures, and builds where depth is limited, this subwoofer's single biggest selling point is its combination of a 3.39in mounting depth and a CEA-2031 compliant 300W RMS rating, which means you get verifiable, usable power and controlled bass without a bulky box. For anyone who needs real bass in limited space, this sub stands out as a pragmatic choice.

Key Features

• Power handling: The CEA-rated 300W RMS (600W program, 1200W peak) provides realistic sustained power handling for consistent bass performance at sensible gain levels.
• Shallow mount design: The 3.39in mounting depth allows installation in tight locations such as truck cabs, hatch areas, and shallow custom enclosures where standard subs will not fit.
• Durable cone: An ultra stiff paper composite cone with a 3D molded high gloss acrylic dust cap improves rigidity and helps maintain clean, accurate low frequencies under load.
• Engineered response: CEA-2031 compliance with a 36Hz-500Hz frequency range and 90dB sensitivity yields predictable performance and easy system matching.
• Installation flexibility: Works well in sealed enclosures (0.5-1.0 cu ft) or vented boxes (1.0-3.0 cu ft), giving installers options to tune for punch or deeper extension.

Who It's For

The Rockville W10T4-S2 is for car audio builders who need authentic bass from a compact 10in sub where depth is limited, such as in pickup trucks, small sedans, or custom shallow enclosures. It suits listeners who want controlled, musical low end for genres like hip-hop, EDM, and rock without oversized boxes.

It is less ideal for those seeking extreme SPL contests or very deep extension below 30Hz; buyers who need maximum cone area and excursion for earth-shaking volume should consider a larger, deeper subwoofer instead.

Pros & Cons

Pros

• Accurate, controlled bass from a CEA-rated 300W RMS spec that reflects real-world power handling.
• Shallow 3.39in mounting depth makes the sub useful in tight or shallow installations.
• Stiff paper composite cone and molded acrylic dust cap contribute to reliable sound and durability.
• Versatile enclosure recommendations let installers tune for punch or low-end extension.

Cons

• Fit can be mixed depending on vehicle; some cars may still present clearance or cutout challenges.
• As a compact 10in shallow sub, it will not match the deep sub-bass output of larger, high-excursion subs.

Frequently Asked Questions

Will this sub fit in shallow factory enclosures?
It is designed for shallow installs with a 3.39in mounting depth, but installers should verify cutout size and rear clearance for your specific vehicle.

What enclosure works best?
It performs well in a small sealed box (0.5-1.0 cu ft) for punchy bass or a vented box (1.0-3.0 cu ft) for more low-end extension.

What amplifier load should I use?
Use an amp that can deliver clean power near the 300W RMS rating into a 2-ohm load for optimal performance and control.
