6.75" 2-Way Concentric Coaxial Speakers

Turn your daily drive into a rolling soundstage with the Diamond Audio DMDX675 6.75" 2-way concentric coaxial speakers, engineered for high-fidelity sound, powerful output, and unbeatable value. Part of the performance-driven DMDX Series, these speakers are built for drivers who want clean, dynamic audio without the premium price tag.

At the core of the DMDX675 is its advanced concentric coaxial design, aligning the tweeter and woofer on a shared axis for improved phase accuracy and seamless sound reproduction. This results in a more natural and immersive soundstage, where vocals sit front and center, highs sparkle with clarity, and midrange detail remains rich and defined.

With 50W RMS / 150W MAX power handling, these 6.75-inch coaxial speakers deliver strong, distortion-free output, making them ideal for both factory systems and entry-level amplified setups. The 86dB sensitivity ensures efficient performance, giving you consistent volume and clarity across a wide range of listening levels.

The frequency response of 60Hz–20kHz allows the DMDX675 to reproduce the full spectrum of sound, delivering tight, responsive bass, detailed mids, and crisp highs. The larger 6.75-inch woofer enhances low-frequency presence, adding depth and impact that smaller speakers simply can’t match.

Engineered with premium materials and Diamond Audio’s trusted design standards, the DMDX675 offers long-lasting durability and reliable performance. Its shallow 1.85-inch mounting depth and versatile sizing make installation easy in a wide variety of vehicles, including cars, trucks, and SUVs.
