Rockin' on the waves

Kicker's KMS67 marine component speaker system will keep things rockin' when you're out on the water. This system broadcasts sound a long way with maximum clarity, so it's a great choice if you like to mix high-volume music with high-energy watersports.

Power plus efficiency

These speakers give you plenty of power, but they're also remarkably efficient. The system's muscular 6-3/4" woofer features a polypropylene cone with a rubber surround housed in a rock-solid cast-aluminum basket. Kicker designed these speakers to fit their tower speaker enclosures.

The adjustable Tractrixhorns use heavy-duty 1.7" compression drivers to send natural-sounding highs right where you want them, so you'll get great sound, even when you crank it up. The system handles up to 200 watts RMS, so add a good amp and you'll definitely be able to hear your music over the wind and waves!

Ready for life on the water

Kicker designed these weatherproof speakers to thrive in the marine environment. The woofers features cones, Santoprene® rubber surrounds, baskets, and grilles that are UV-treated to protect the speakers from sun damage, while the splash-resistant sealed inner works shrug off damage from stray waves, rain, and spray. Stainless steel hardware guards against corrosion.

Features

Marine-ready: The Kicker KMS67 woofers and tweeters are both designed to mount in standard 6-1/2" speaker cans. Each driver's crossover is mounted on the back of the basket, behind the magnet. They are engineered to meet or exceed industry standards for environmental humidity and corrosion, and for material degradation due to UV exposure.

Tweeter: The 1.7" dome tweeters are horn loaded compression drivers (HLCD) with titanium diaphragms and phase plugs coupled to 60° vertical by 90° horizontal advanced Tractrix horns. A jumper wire on the crossover board allows you to change the tweeter output level; choose 0 dB (flat) or +6 dB (recommended when using two pair of woofers).

Mounting: The woofers and tweeters have the following mounting dimensions:

  Speaker Size Mounting Depth Mounting Height Flange Height Cutout Diameter Frame Diameter
Tweeter 6-3/4" 7.31" 0.53" 0.53" 5.57" 6.83"
Woofer 6-3/4" 3.82" 0.43" 0.43" 5.646" 6.6"

Crossover: The crossover for each driver is mounted on the back of the basket. The crossover point is 1,700 Hz for each; the slopes are 18 dB/octave high pass for the tweeters and 12 dB/octave low pass for the woofers.

Terminals: Both the tweeter and midrange have spring post wire terminals; they will accept bare wire up to 14-gauge.

Grilles: The KMS67's woofer grilles are a bolt-through spoke design, made from high-impact plastic.
