More Control, More Power,
More Everything
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!
The dX7 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.
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.
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.

Great high end, tight low end.
Weaknesses:
Only thing, cant swivel the tweeter assembly, and you cannot find grills (usually not an issuew if you have 5x7 factory holes)
Review:
These speakers are fantastic!! I have a system in my truck that is comprised of all DX7 series speakers. I have a pair of Dx7's, Dx9's, DX3000 tweeters, and 2 DX10 subs. The sound is unreal. I listened to alot of speakers and i found polk audio to have the nicest sounding and most detailed high and midrange. And the subwoofers are ridiculously tight. Do not hesitate the spend the little extra cash for these speakers. The quality is definately present and you wont be disappointed Jeremy Warenzek (Polk man for life)
