Our take on the Diamond Audio D310D4.2

by Jo Greene

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.

Rockin' D3 Series 10" sub

You hit the highway and crank the stereo, but your factory bass just can't keep up. Diamond Audio designed D3 Series subwoofers for high-performance bass in your car — you'll hear lots of heavy, powerful low notes that make for a very entertaining ride, even if it's just across town.

Heat dissipating woofer

This 10" D3 sub features a light, responsive copolymer cone and large-roll rubber surround for precise cone movement, so you can count on strong, accurate performance. The stamped aluminum dust cap directs heat away from the motor structure, and helps prevent heat from getting trapped in your subwoofer enclosure.


Aluminum voice coils stay cool

Interior cooling

Diamond Audio furnishes this sub with hefty 2-1/2" aluminum-coated copper voice coils that dissipate heat for extended power handling. Proprietary Venturi venting in the basket and pole piece funnels warm air away from the sub's interior, and that means the sub stays cooler and happier. The dual 4-ohm voice coils give you more options for wiring the sub into your system, and make it easy to add a second D3 sub later on.


Non-resonant basket resists distortion

The heavy-gauge stamped steel basket gives this sub the strength and stability it needs to rock hard for the lifetime of your system. Diamond Audio forms this basket using a unique stamping technique that virtually eliminates unwanted resonance, so your favorite music sounds just as the artist intended.


Diamond Audio goes the extra step

Dual spider assembly

In most subs, the spider assembly is glued to the basket. In D3 subs, Diamond Audio uses a dual spider assembly that is glued and screwed to the basket to virtually eliminate the possibility of mechanical failure.

Features

Dual 4Ω Voice Coils: The D310D4.2 features dual 4Ω voice coils. When the voice coils are wired in parallel, the woofer presents a 2Ω load; when wired in series, the woofer presents an 8Ω load.

Cone: The textured copolymer cone has an aluminum dust cap to help draw heat away from the voice coil.

NBR Surround: The woofer features a Nitrile Butadiene Rubber (NBR) surround, a synthetic rubber that stands up to the harsh automotive environment.

Spring-Post Terminals: The spring-post terminals will accept pin connectors, single banana plugs, and bare wire up to 8-gauge.

Concealing Ring: The included rubber trim-ring provides a mounting gasket and gives the subwoofer a finished look.

Enclosure Compatibility

Sealed Enclosure: The recommended sealed box volume is 0.75 cubic feet.

Vented Enclosure: The recommended vented box volume is 1.0 cubic feet with a 3" diameter, 11" long port; resulting in a tuning frequency of 39 Hz. A 30 Hz sub-sonic filter is recommended for vented enclosures.
