Rockford Fosgate T1S2-10 10" 2-Ohm Slim Subwoofer

The Rockford Fosgate T1S2-10 is a 10-inch shallow-mount car subwoofer designed for systems where mounting depth is limited. Its single 2-ohm voice coil configuration suits compatible mono amplifiers and single-subwoofer installations. It is intended to add low-frequency output without requiring the depth of a conventional full-size subwoofer.

This model is a practical option for trucks, coupes, and other vehicles where enclosure space is constrained. With 500 watts RMS power handling, it is built for an amplifier matched to its continuous power rating and 2-ohm nominal load. The slim 3.01-inch mounting depth helps simplify placement in compact custom enclosures.

The T1S2-10 combines a glass-fiber cone, foam surround, aluminum dustcap, and dual Nomex spiders. These components support controlled cone movement and durability during regular bass playback. Its 83 dB sensitivity and 28-250 Hz frequency response provide useful low-frequency extension when installed in an appropriate enclosure.

Rockford Fosgate uses EVCC and SYMS motor technologies in the T1 Slim platform to package the motor and voice-coil system in a shallow format. The 2.5-inch, four-layer single voice coil and neodymium motor are paired with up to 15 mm of linear excursion. This engineering approach allows the driver to operate in installations with limited rear clearance.

The T1S2-10 can be used in sealed or vented custom enclosures, with manufacturer data providing designs for each approach. A sealed enclosure supports a compact installation, while the recommended vented design is tuned for deeper extension. For vented use, Rockford Fosgate recommends an infrasonic filter to help limit unnecessary low-frequency excursion.

Key Features

• Shallow-Mount Design: 3.01-inch mounting depth supports space-conscious installations.
• Single 2-Ohm Voice Coil: Matches amplifiers stable at a 2-ohm load.
• 500-Watt RMS Rating: Handles substantial continuous amplifier power when correctly matched.
• 15 mm Linear Xmax: Supports controlled cone travel for bass reproduction.
• Neodymium Motor: Helps achieve a compact shallow subwoofer profile.
• Dual Nomex Spiders: Help stabilize the moving assembly during operation.

Design & Installation

The T1S2-10 uses a die-cast aluminum basket, glass-fiber cone, foam surround, aluminum dustcap, dual Nomex spiders, and a neodymium magnet. Its 10.83-inch overall diameter, 9.13-inch cutout requirement, and 3.01-inch mounting depth should be verified against the enclosure and vehicle before installation. The driver uses 10 AWG slot-loaded speaker terminals for a secure high-current connection.

Use a properly built enclosure that accounts for the subwoofer's 0.028 cu. ft. displacement and provides adequate mounting clearance. Manufacturer data lists a 0.80 cu. ft. sealed design or a 1.50 cu. ft. vented design, with the vented recommendation using a 4-inch-diameter, 14.17-inch-long port tuned to 40 Hz. Match the subwoofer with an amplifier rated appropriately for a 2-ohm load and use an infrasonic filter in vented applications.
