DS18 6.5" Ultra-Slim 1.16" Depth 120W RMS 4-Ohm Mid-Range Neo Pro Loudspeaker

This Listing Includes

• (1) DS18 6.5" Ultra-Slim Speaker PRO-INS6.4

The DS18 PRO-INS6.4 was engineered for one purpose: delivering real midrange output where traditional speakers simply cannot fit. With an ultra-slim 1.16-inch mounting depth, this 6.5-inch neodymium midrange speaker is the perfect solution for shallow, zero-clearance installations without sacrificing output or clarity.

Designed to Fit Anywhere

At just 1.16 inches deep, the PRO-INS6.4 excels in tight spaces such as motorcycle fairings, side panels, custom pods, door panels, and compact enclosures. It’s a true drop-in solution when space is limited, but sound quality still matters.

Powerful and Efficient

Rated at 120 watts RMS and 240 watts MAX, this 4-ohm midrange delivers strong output with less amplifier power thanks to its 95 dB sensitivity. The 1.5-inch KSV voice coil, lightweight CCAW windings, and neodymium motor work together to produce fast, accurate midrange response that stays clean even at higher volumes.

Focused Midrange Performance

Covering a frequency range of 80 Hz to 6 kHz, the PRO-INS6.4 is optimized for tight, punchy midrange reproduction. For best performance and reliability, a 120 Hz high-pass crossover is recommended.

Built for Daily Use

The speaker includes a custom steel mesh grille with cloth protection, helping shield the cone from dust and debris. A paper cone, cloth surround, and matte black steel basket provide a durable, balanced design suitable for everyday driving and demanding installations.

Whether you're filling gaps in a crowded build or stacking multiple drivers in a compact layout, the DS18 PRO-INS6.4 delivers full-size sound from an ultra-low-profile package that fits almost anywhere.
