6"x 8" 3-Way Coaxial Speakers

Bring your factory audio system back to life with the Diamond Audio DMD683 6"x 8"   3-way coaxial speakers, engineered for enhanced clarity, balanced performance, and unbeatable value. As part of the dependable DMD Series, these speakers are designed to deliver a noticeable upgrade over OEM sound, with improved detail, fuller output, and clean, dynamic audio.

The 3-way coaxial design integrates a dedicated woofer, midrange driver, and dual tweeters, expanding the frequency range and improving overall sound staging. Equipped with a 13mm PEI dome tweeter and a 20mm silk dome tweeter, the DMD683 produces crisp highs and smooth upper frequencies, ensuring vocals and instruments remain clear and defined even at higher volumes.

At the core of the system is a high-performance 6"x 8" woofer featuring a high-density NBR half-roll surround, designed to promote smooth cone movement and increased linear excursion. This results in tight mid-bass response and accurate midrange reproduction, giving your music depth and balance across multiple genres.

Built for long-lasting performance, the DMD683 incorporates chemically treated voice coils and a cross-flow basket frame design, improving thermal heat dissipation and allowing the speakers to maintain consistent, distortion-free output during extended listening sessions. With Klippel® DA optimized motor and suspension symmetry, these speakers deliver precise, balanced sound with reliable durability.

With 40W RMS / 80W MAX power handling, the DMD683 is ideal for factory head units and entry-level amplified systems. Its 2.18-inch mounting depth and 6.92" x 4.95" cutout dimensions ensure easy installation in most cars, trucks, and SUVs.
