DS18’s PRO-INS6.4 was built for one thing: fitting where nothing else can. With just 1.16” mounting depth, this neodymium-powered 6.5" midrange loudspeaker delivers pro-grade output in the tightest installs possible.

Designed to Fit
At just 1.16 inches deep, the PRO-INS6.4 is perfect for builds with zero clearance—motorcycles, side panels, custom pods, and tight-door installs. It’s the ultimate drop-in solution for adding real volume where standard mids won’t fit.

Plenty of Punch
Push 120W RMS / 240W MAX through this 4-ohm midrange speaker with confidence. The 1.5” KSV voice coil, CCAW windings, and lightweight neodymium magnet create fast, tight response with 95dB sensitivity that stays clean when cranked.

Focused Midrange
The 80Hz–6kHz frequency range makes this speaker perfect for tight, mid-focused setups. For optimal performance, pair it with a 120Hz high-pass crossover to keep it LOUD.

Built to Last
Includes a custom steel mesh grille with cloth backing to block dust and splash. The paper cone, cloth surround, and matte black steel basket are optimized for daily use without faltering in tone or response.

DS18’s PRO-INS6.4 gives you full-size sound in a low-profile package that fits anywhere. Stack them, or fill the gaps your other mids can’t reach
