The dX Series: Drop em in, turn em up!
dX coaxial speakers are the drop-in solution for high performance and high efficiency. Bass? It's tight, deep and full. Mids and highs? We got em smooth and detailed. Imaging? dX delivers spacious depth and sound staging. Price? Less than you'd expect for stuff this good.
The dX4 Features:
- Polymer/mica composite cones for enhanced performance and durability.
- Blue Tri-Laminate woven silk composite dome tweeters: "Bright without bite."
- Polk Audio's exclusive Dynamic Balance technology for superior response with all kinds of music.
- High-tech Elastomer rubberized-plastic surrounds for reliable durability and better performance.
- 1" diameter driver voice coil for superior bass and power handling.
- Extra long, precision wrapped, vented voice coils for superior cooling, longer linear throw, and high power-handling.
- dX Tweeters feature little powerhouses: the lightweight but powerful Neodymium magnet -- smaller than traditional ceramic magnets, but 7 to 10 times more powerful!
- Multi-hole mounting patterns for drop-in convenience in most any ride. That means EZ installation in most factory speaker locations.
High-tech materials constructed with state-of-the-art techniques prime the dX Series to take all the punishment and power you can dish out: they're durable and torture-proof. And they're efficient enough to run right off your existing high-power head unit. You don't have to blow more gas money on an extra amplifier. Unless, of course, you want to!
If you're serious about your car stereo -- don't bother with cheap-o speakers. Go for the gusto of the dX Series Loudspeakers. They give you the ultimate in performance, flexibility, and control. They contain some amazing technology -- the kind that makes them tough enough to take the heat, and powerful and efficient enough to inspire many a road trip.
