All DS18 PRO-CF speakers are:
- Water-resistant with carbon fiber cones
- Designed for motorcycles & powersports installs
- Built to get LOUD and stay CLEAR at highway speeds
Let's break down every PRO-CF model and explain what makes them different.

DS18 PRO-CF SL Series: Space Savers That SLAP!
Not every bike has room for deep baskets or oversized builds. That’s where the SL Series comes in—made for tight installs that demand full-volume impact.
These slim-profile loudspeakers use the same water-resistant carbon fiber cone, rugged steel basket, and sharp clarity you’d expect from DS18—but with a shallower mounting depth that lets them slide into saddlebags, fairings, or pods without a fight.
Whether you’re building around bag lids or sneakily stuffing your front end, the SL Series proves that shallow doesn’t mean soft.
With sizes in both 6.5” and 8”, these speakers deliver serious flexibility for any high-power, multi-amp, or limited-space build.

- Frequency Response: 60Hz–12kHz (8") | 80Hz–12.5kHz (6.5")
- Crossover Recommendation: 80Hz for 8", 100Hz for 6.5"
- Materials: Carbon fiber cones, CCAW voice coils, Kapton formers
- Form Factor: Slim basket design for tighter fitments
- Motor Strength: Traditional ferrite magnets keep the slam strong
Why Riders LOVE the PRO-CF SL Series?

- Durable enough for cross-country weather, yet clean enough for the show scene
