Product Overview
Description

- 240W RMS (program) / 480W MAX
- 8-ohm impedance, 112dB sensitivity
- 1.5" / 38mm titanium voice coil
- Ferrite magnet, 15 oz
- Aluminum body with square mounting flange
- 2.5" mounting depth
- Sold individually (each)
Product Overview
High end that carries. The PRO-TWX6 puts a 1.5" titanium voice coil behind a 15 oz ferrite motor and a square 4" x 4" aluminum body, and at 112dB it does not need much power to cut through a wall of midrange. Response runs from 1.7kHz to 20kHz, so it picks up where your mids leave off and takes the top end the rest of the way.
The square flange makes for a clean, symmetrical mount, and a 2.5" mounting depth clears most door and pod locations without major fabrication. Sold individually (each).

FAQs

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.
