Included In This Listing:

• (2) DS18 DXQ6.9CX 4_Ohm 6×9″ Coaxial Speakers

The DS18 DXQ6.9CX delivers rich, distortion-free audio with powerful 150W RMS and smooth highs from its silk dome tweeter. Designed with premium materials like a yellow straw/composite foam cone and rubber surround, this coaxial speaker is built for clarity, durability, and enhanced heat dissipation. With 4-ohm impedance and excellent integration flexibility, it’s ideal for car doors, aftermarket audio installs, or sound upgrades in vehicles seeking dynamic and precise full-range sound.

Power & Performance

With 150W RMS and 300W MAX power handling, the DXQ6.9CX delivers consistent performance across a full frequency range (45Hz20kHz). Designed for high-output systems, it maintains clarity even at loud volumes.

Premium Cone & Tweeter

The yellow straw and composite foam woofer cone, paired with a durable rubber surround, offers tight bass and durability. A 1″ silk dome tweeter with a neodymium magnet ensures smooth highs, while the adjustable swivel mount allows precise sound staging.

Engineered for Vehicle Integration

With a 4-ohm impedance and 1.2″ voice coil, this speaker is ideal for a wide range of car audio builds. A recommended 60Hz high-pass crossover balances low-end warmth with crisp mids and highs.

Built for Longevity

Featuring an aluminum basket and push terminals, the DXQ6.9CX is built to handle heat and vibration without fatigueideal for long drives or SPL demo rigs.

Sold in Pairs

Each set includes two speakers – perfect for front-stage upgrades or complete stereo enhancement.
