DS18 PROJECT360.MB104NX / MB108NX 10" Mid-Bass Loudspeaker with Neodymium Magnet & Rotating Recone Design — 2000W MAX
Product Overview
Description
The DS18 PROJECT360 10" mid-bass loudspeaker pairs a neodymium magnet with a 4" glass fiber voice coil, rated 1000W RMS and 2000W MAX, and it uses DS18's rotating recone design so a worn cone assembly can be swapped without glue. It plays 45Hz to 6kHz at 95 dB sensitivity, and you choose a 4-ohm or 8-ohm version. Price is per speaker (each).
Product Overview
The PROJECT360.MBNX series is designed for high-output audio applications. These mid-bass speakers feature a neodymium magnet motor structure that delivers strong magnetic performance while reducing overall weight, and a large 4-inch voice coil that provides increased thermal capacity for demanding power requirements.
The patent-pending Rotating Recone Design is an innovative, serviceable system for quick and easy maintenance and repair: the damaged module is removed, the basket is cleaned, and a new recone is installed. Recone kits for this speaker are listed separately on this store.
Key Features
- Patent-Pending Rotating Recone Design: made for quick and easy replacement of the speaker's moving components
- Neodymium Magnet: lightweight neodymium motor for more power and sound projection
- Competition-level output with minimal amplifier power
- No glue, no downtime: the rotating design eliminates the traditional glue curing process
- High power handling: 4" glass fiber voice coil and carefully selected materials increase power handling and thermal management
- High-efficiency design: aluminum basket and non-pressed paper cone for rigidity, improved heat dissipation and reduced resonance

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.
