Our take on the Rockford Fosgate T110D4

by Steven Johnson
Rockford Fosgate

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

The fanatics at Rockford Fosgate are always testing the limits of bass — and that's how Power Series Stage 1 subwoofers were born. Ideally suited for use with Power Series amps, everything about these innovative woofers screams "hard-hitting sound."

The aluminum parabolic cone has a high-excursion rubber surround for the kind of travel that ensures max bass. The massive 102-ounce double-stacked magnet structure and oversized 3" copper-clad aluminum voice coils handle just about all the power you can throw at them. Spider venting keeps the woofer cool even when you run it long and hard.

The T110D2 10" subwoofer can blast away in either sealed or vented enclosures. The dual 4-ohm design lets you wire for high output or a multiple woofer setup.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.

Features

Dual 4-ohm Voice Coils: This woofer features dual 4-ohm voice coils that offer flexibility in wiring. When the voice coils are wired in parallel with each other, the woofer presents a 2-ohm mono load. When the voice coils are wired in series with each other, the woofer presents an 8-ohm mono load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 4-ohm load.

Woofer: The aluminum parabolic woofer cone is lightweight and extremely strong, giving the woofer very high power handling, low distortion, and superior bass response.

High Excursion Thermo-Rubber Surround: The use of a "tall/skinny" high excursion thermo-rubber surround allows for linear cone travel on a high excursion driver without reducing cone area.

Parabolic Triangular Cone Geometry Support System: By bonding an aluminum parabolic dust cap of equivalent size to the cone body, a balanced triangular structure is created. This system reduces piston flex and eliminates cone distortion.

Mirror Image Symmetrical Spiders: Dual-opposing spiders offer superior mechanical stability during high excursions, while maintaining linear travel.

Spider Support Ring: This integrated ring increases the bonding surface area between the voice coil former and spider, establishing a stronger joint. The result is increased mechanical power handling under high power/high excursion situations.

Anodized Aluminum Voice Coil Former: Aluminum voice coil formers offer superior heat dissipation over other commonly used materials. The hard-anodized finish increases the former strength. These two factors combine to improve the overall power handling characteristics of the subwoofer.

Precision Cast Aluminum Alloy Basket: A two-piece "basket in a bucket" design adds rigidity and eliminates multiple acoustic resonances. Additionally, the large aluminum mass helps reduce voice coil former temperature and increase power handling.

Double Stacked Magnet Motor Assembly: The stacked magnet assembly is used to create a powerful linear motor with increased excursion capability for superior bass output.

Slot-Loaded Spring Terminals: The proprietary, slot-loaded spring terminals will accept pin connectors and up to 8-gauge bare wire.

Concealing Ring: Once the subwoofer is mounted, the metal concealing ring can be installed to hide the mounting screws, giving the subwoofer a finished look.

Enclosure Compatibility

Recommended Sealed Box Volume: Rockford Fosgate recommends mounting this woofer in a sealed enclosure with an internal volume of between 0.5 cu/ft. and 1.0 cu/ft. with an ideal volume of 0.75 cu/ft.

Recommended Vented Enclosures: Rockford Fosgate recommends mounting the woofer in a vented enclosure with an internal volume of between 1.0 cu/ft. and 2.0 cu/ft. with an ideal volume of 1.5 cu/ft. One 4" port is recommended at the following lengths for each size enclosure:

Box Size Box Volume Port Length
Minimum 1.0 cu/ft. 18"
Recommended 1.5 cu/ft. 11"
Maximum 2.0 cu/ft. 7.5"
