Product Overview

 

The Project360.84 is a high-sensitivity mid-high loudspeaker engineered for powerful output, rapid serviceability, and performance-driven installs. Designed with DS18’s innovative rotating recone system, this speaker redefines how quickly and easily field repairs can be handled.

Instant Recone, Zero Downtime
Unlike traditional speakers that require glue, curing time, and complex rebuilds, the Project360.84 features a rotating recone design that allows the entire cone assembly to lift cleanly from the basket and lock back into place with a smooth twist motion. No adhesives, no drying, and no waiting — recones can be performed on the spot, minimizing downtime and keeping systems playing.

Built for Plug-and-Play Repairs
Designed for fast replacement and simplified maintenance, this system enables true lug-and-play recones. Whether for professional audio applications, high-output builds, or demanding environments, repairs become quick, predictable, and efficient.

High Sensitivity, High Impact
With a sensitivity rating of 100.2dB, the Project360.84 delivers exceptional output with minimal power. The lightweight curvilinear cone and efficient motor structure ensure strong midrange projection and crisp mid-high response, making it ideal for loud, clear vocal reproduction.

Engineered for Performance and Durability
A 1.75” voice coil with Kapton former, cloth surround, and aluminum basket provides strength, thermal stability, and long-term reliability. Built to handle aggressive use while maintaining clarity and control.

Bring louder output, smarter service ability, and next-level recone convenience to your system with DS18’s Project360.84.

FAQs

Please read our FAQs page to find out more.

RMS vs. MAX power — which number do I actually care about?

RMS is what your gear handles continuously; MAX is the short burst it can survive without complaint. Match your amplifier's RMS output to your speakers' RMS rating — sizing off the MAX number is how magic smoke gets released.

What does the IP65 rating on DS18 marine gear actually mean?

It's dust-tight and rated against low-pressure water jets from any direction — built for spray, rain, and the occasional wave over the bow, not for full submersion. If something's going somewhere it could sit underwater, that's a different conversation entirely.

How do I match an amplifier to my speakers without guessing?

Add up the RMS rating of everything the amp will power, and pick an amp whose RMS output (at your speakers' impedance — usually 4-ohm) lands close to that total. Undersized is thin sound; wildly oversized is a fast way to blow a voice coil.

Can I mix marine-grade gear into a standard car audio setup, or the reverse?

You can run marine-grade gear in a car — it's just over-built for that environment, no downside besides cost. Running non-weatherproof car audio gear in an open UTV or boat is the direction that causes problems.

What gauge wiring kit do I need?

It scales with your amp's power draw and the length of the run — DS18's OFC kits come in 4-gauge and 8-gauge for a reason. Undersized wiring on a high-draw system is a voltage-drop and heat problem waiting to happen; when in doubt, size up.
