At Diamond Audio we are always striving to be the best.  And when you already build the HEX series, the most critically acclaimed speaker systems available for the automobile, this can be a very challenging goal to achieve. Our new HEX Pro takes everything we have ever learned about loudspeaker development to a whole new level.  We start with an improved version of our award winning HEX Cone and our patented TDX Technology and combine that with the new Pro crossover for the very best speaker system ever offered for the mobile environment.  Period!  Conventional speakers use large ceramic magnets surrounding the voice coil.  These magnets retain heat.  TDX™ motors use a small but very efficient neodymium magnet mounted inside the voice coil and are nearly 5 times more efficient than conventional designs.  In conjunction with the motor design, TDX™ Technology utilizes a die-cast aluminum basket that helps to act as a heat sink for the encapsulated motor structure.  This makes for the most advanced cooling process of any speaker available.


D3 speakers start with the same high density proprietary composite ABS frame found in our D6 convertible systems. They feature a butyl rubber surround and a graphite injected polypropylene cone for exceptionally accurate bass response.  Whether choosing a component or a coaxial system all D3 speakers utilize 1” aluminum dome tweeters.  Our D3 component systems use an outboard 18dB high pass/ 12dB low pass model specific crossover with RAF (Rear Acoustic Fill) allows an additional pair of speakers to be added without the need of another amplifier.   You won’t find a better combination of value and performance anywhere.
