Open & Smooth Sound

The "Open & Smooth" sound concept of our industry-leading speakers delivers both sonic excellence and performance. The open-staging and smooth transition of driver response makes for an immersive experience that is truly the ultimate in-car sound.

Designed with performance in mind

To ensure optimal sound reproduction, the entire D-series takes a purist approach incorporating a 2-way design with separate tweeter and woofer. It is available as a component speaker system or space-saving coaxial package.

Crisp highs and punchy lows

The tweeters used by the D-series can easily outperform the competition to produce smoother and clearer notes. Meanwhile, a newly developed Aramid Fiber Interlaced injection molded polypropylene speaker driver outputs deeper and more powerful bass.

Unparalleled installation flexibility

Besides a built-in swivel function, the D series tweeter also supports a tri-position mounting kit for flush, surface and bracket mount, so that you can effortlessly conceal it behind a grille on your vehicle’s dashboard or door.
