About dX Series Full Range Speakers

dX coaxial speakers are the drop-in solution for high performance and high efficiency. Bass—tight, deep and full. Mids and highs—smooth and detailed. Imaging—spacious depth and sound staging.

Drop them into practically any factory location. dX coaxials feature multi-hole mounting patterns for drop-in convenience in most any ride, and high-tech materials constructed with state-of-the-art techniques so they can take the punishment and power you dish out. They're durable and torture-proof.

Run them off your existing high-power head unit. Because they're efficient enough to play loud using the power right from your head unit, you don't have to blow more gas money on an extra amplifier. Unless, of course, you want to! dX coaxes can take it, any way you dish it out.

The polymer/mica composite cone in the dX coaxial loudspeaker stands up to all sorts of torture, cancels performance-robbing resonance, and adds endurance. Environmentally stable rubber surrounds withstand climate conditions that rot lesser speakers. dX cones shrug off moisture and heat like a raincoat.

The drivers in the dX Coaxes have a 1" voice coil. That's a big voice coil for a coaxial. It handles big power. You can pump these dXs full of power and still get crisp sound. The tweeters are tri-laminate silk composite domes - for better damping and smoother response - with Neodymium Alloy magnets; these monster-magnets are smaller than traditional ceramic magnets, but 7 to 10 times more powerful. That means awesome response in a speaker that fits.

Then there's our exclusive recipe for tuning out distortion-producing speaker resonance: Dynamic Balance. Dynamic Balance results in greater detail no matter what you're listening to; dX sound is always clean and clear. Only Polk's got it.
