Product Overview

Description

The 6PRO600NSE-4 is a 6.5" sealed-back mid-high pro-audio loudspeaker with a neodymium motor, sold as a single. Rated 300W RMS and 600W MAX at 4 ohms with 97dB sensitivity, it covers 300Hz to 18.6kHz with a recommended 480Hz high-pass, built for line-array style builds and pods where a compact, loud mid-high is needed, with no separate enclosure. IP65 water-resistant, aluminum basket in matte black, 2" glass-fiber voice coil.

Key Features

  • 6.5" sealed-back mid-high loudspeaker, neodymium magnet
  • 300W RMS / 600W MAX at 4 ohms, 97dB sensitivity
  • 300Hz–18.6kHz, recommended high-pass 480Hz
  • IP65 water-resistant, water-resistant paper cone, cloth surround
  • 2" glass-fiber voice coil with CCAW winding, copper demodulating ring

  • Sold as a single unit

Product Overview

The sealed-back design means the 6PRO600NSE-4 needs no separate enclosure to play its 300Hz–18.6kHz band. Neodymium keeps it light and shallow (2.6" mounting depth, 5.65" cutout). Run it off a channel rated around 300W RMS at 4 ohms with a 480Hz high-pass.

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.
