Overview

DS18 PRO-ZT8 8-Inch Midrange Loudspeaker with Integrated Bullet Tweeter – 275W RMS / 550W Peak

The DS18 PRO-ZT8 is a high-performance 8-inch midrange loudspeaker designed for vehicles requiring powerful sound output with exceptional clarity across the mid and high frequencies. Engineered for enthusiasts and professionals alike, the PRO-ZT8 combines a robust midrange driver with an integrated aluminium bullet tweeter, offering a hybrid design that delivers aggressive output and high-frequency extension from a single speaker unit.

With a maximum power handling of 550W and 275W RMS, the PRO-ZT8 is built for high-SPL systems where volume and detail are essential. The pressed paper cone and high-roll cloth surround ensure clean, accurate response and mechanical stability at high power levels, while the 1.5" high-temperature voice coil and ferrite magnet structure ensure long-term durability and thermal efficiency.

Key Features:

Power Handling: 275W RMS / 550W Peak. Capable of delivering extremely loud, clean output suitable for professional-grade systems.

Integrated Aluminium Bullet Tweeter: Built-in tweeter delivers sharp, extended highs for improved upper frequency performance.

Cone Material: Pressed paper for optimal balance of strength, responsiveness, and tonal accuracy.

Surround: High-roll cloth surround allows greater cone excursion and maintains linearity under high output.

Voice Coil: 1.5” high-temperature Kapton voice coil supports high power handling and reliability.

Magnet Structure: High-strength ferrite magnet for maximum efficiency and consistent output.

Frequency Response: 85Hz – 20kHz. Wide range covers midrange fundamentals through extended treble, ideal for front-stage and door installations.

Sensitivity (1W/1m): 96 dB. High-efficiency design delivers loud output with minimal amplifier power.

Impedance: 4 ohms. Optimised for multi-speaker and competition systems; also available in 4-ohm version (model dependent).

Mounting Depth: 79mm. Supports standard 8-inch installation locations with ample clearance.

Applications:
The DS18 PRO-ZT8 is ideal for SPL and high-output sound systems in cars, trucks, or custom installations. Whether used for midrange fill or paired with dedicated subwoofers and compression drivers, this speaker provides aggressive, accurate audio reproduction and professional-level reliability for demanding audio setups.

Powered by a neodymium magnet, the PRO-ZT8 generates an exceptional magnetic flux density in the air gap, resulting in unparalleled action force in the voice coil. This means you'll experience powerful and dynamic sounds like never before.
