Product Overview
Description
DS18 PRO-TWN4 3" High Compression Neodymium Hybrid Driver/Tweeter 280 Watts 1" Pen 4-Ohm Vc
DS18's PRO-TWN4 has all the looks of a driver but has been compactly sized to fit into super tweeter dimensions. This super tweeter's 1 inch voice coil can handle 140W RMS and 280W Peak. Comes with a neodymium magnet which increases the tweeter's efficiency and lowers the weight dramatically. Each tweeter comes with an included bass blocker for extra protection against frequencies that would otherwise damage the tweeter so you can feel safe your equipment can play loud and long. These tweeters have a very high sensitivity of 105 dB so they do not require full power to get extremely loud. This opens you up to multiple amp choices and gives you the versatility everyone looks for in powering and using your new tweeters.
Highlights
- Full size pro audio super tweeter producing crazy loud high range notes for your system.
- Designed to fit in most spaces with slight modification or fabrication.
- Built in grills help protect the inner workings of your super tweeter.
- Easily repaired in minutes (replacement diaphragm: PRO-TWN4VC).

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.
