Product Overview
DS18 PRO-INS6.4
6.5” Ultra Slim Mid-Range Loudspeaker with Neodymium Magnet
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 small spaces.
Designed to Fit
With 1.16 inches mounting depth, the PRO-INS6.4 is perfect for builds with shallow depth mounting (i.e. motorcycles, side panels, custom pods, and low depth door installs). It’s the ultimate drop-in solution for adding pro audio solution 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 with less amplifier power, making it more efficient and easier to drive
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 water 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 shallow package. Add the pro audio your vehicle needs.
