Our verdict

A single midrange driver for door or dash installs, with power ratings and cutout dimensions clearly stated. It is sold alone, so a stereo pair needs two, and it is not water resistant.

Overview

DS18 makes the PRO-GM6B as a bullet-style midrange loudspeaker for car doors. A paper cone, cloth surround and steel basket form the driver, and a ferrite magnet moves a kapton voice coil.

Stated cutout and depth figures make planning an install straightforward, and the power ratings give a clear match to an amplifier. The limitation is that it is one speaker with a midrange-only band, so full-range sound needs other drivers.

Who it's for

Installers working on a custom system, who measure cutouts and match RMS power to an amplifier, are the target. Drivers wanting a drop-in full-range pair or a marine-rated speaker should look elsewhere.

Pros and cons

Pros
  • Cutout and mounting depth stated
  • Steel basket and ferrite magnet
  • Peak and RMS power both given
  • Voice coil and magnet sizes listed
Cons
  • Sold as a single speaker
  • Not water resistant
  • Spec table has unrelated wireless entries

Performance notes

A midrange driver handles the vocal and instrument band, so output depends on matching the stated RMS power to the amplifier and sealing the mount so the cone does not lose air to the door cavity. Higher sensitivity means more volume per watt, while the stated impedance sets the load on the amplifier. Mounting depth must clear whatever lies behind the door panel.

Frequently asked questions

How do I protect the DS18 PRO-GM6B from moisture?

The listing marks it not water resistant, so install it behind a door panel or other barrier rather than in an exposed spot.

Is the DS18 PRO-GM6B sold as a pair?

No. The title says one speaker, so a stereo pair needs two.

Is the DS18 PRO-GM6B a subwoofer or tweeter?

No. It is a midrange driver, and the frequency response starts well above subwoofer territory.
