Built for Loud Systems

The DS18 PRO-ZT69 is a 6x9 inch two-way midrange loudspeaker designed for car audio enthusiasts who prioritise high output. It handles 275 Watts RMS and 550 Watts peak power at 4 Ohms. A built-in bullet tweeter extends the frequency response from 65Hz to 22KHz. The 98 dB sensitivity ensures strong volume levels even with moderate amplifier power.

Ferrite Magnet and Kapton Coils

A 27oz ferrite magnet structure drives the 1.5 inch Kapton voice coil, while the tweeter uses a 1 inch Kapton coil with CCAR winding and an aluminium-magnesium alloy diaphragm. The 85mm mounting depth fits standard 6x9 openings in most vehicle doors or rear decks. Black finish matches factory aesthetics. The 4 Ohm impedance suits common car amplifiers without special wiring requirements.

Upgrade from Factory Coaxials

This speaker replaces basic original-equipment coaxials when the system demands higher power handling and clearer midrange detail. The jump is worth it for owners adding an external amplifier who need 275 Watts RMS capacity. It is not for buyers seeking deep sub-bass below 65Hz or those installing in spaces shallower than 3.34 inches.

Questions about this item

What sensitivity does the 4-ohm PRO-ZT69 deliver at 1 watt?

The speaker is rated at 98 dB sensitivity measured at 1 watt and 1 metre.

How much depth is required behind the 6x9-inch panel to mount the speaker?

Mounting depth is 85 mm, which is 3.34 inches from the mounting surface to the magnet rear.

What wiring step is critical when connecting the built-in bullet tweeter?

Ensure the tweeter leads are wired with correct polarity and that the crossover network is engaged so the tweeter only receives frequencies above its operating range.
