Product Overview

Engineered for Superior Efficiency
With an ultra-high sensitivity of 98dB, this driver gets LOUD with less power, making it an easy upgrade for riders and installers who want MAX output over road and wind noise, without straining their amplifier.

Built for Harsh Environments
A water-resistant coated paper cone and dust cap keep performance strong in any conditions. The 69PRO300MB-8 delivers strength where it counts, while its sealed-back design protects the motor assembly in tight or exposed installs.

Precision Performance with Lower Distortion
Equipped with a demodulating copper ring, the 69PRO300MB-8 maintains a wider, more stable magnetic field for smoother coil movement and significantly reduced distortion. The result is mid-bass response that stays clean and aggressive from 50Hz to 12.5kHz.

Perfect for High-Impact Builds
This speaker thrives in motorcycle fairings and car door panels where strong mid-bass is essential for a balanced sound system.

Want a speaker that hits harder, lasts longer, and sounds better than any regular mid-bass? The 69PRO300MB-8 is the most reliable upgrade you can make!
