Key Features

Flagship 11-Inch Woofer Platform

At the heart of the WB11 is a dedicated 11-inch subwoofer driver designed to move more air and generate greater low-frequency output than smaller spare tire subwoofers.

The larger diaphragm area allows deeper bass extension and stronger impact while maintaining excellent control and musicality.

High-Power Integrated Amplifier

The WB11 features a powerful built-in amplifier rated at 350W RMS and 600W maximum power, providing the energy required to reproduce demanding bass passages with confidence and authority.

This integrated design simplifies installation while delivering impressive performance.

Premium Spare Tire Installation Solution

Designed specifically for installation within the spare wheel well, the WB11 remains hidden beneath the cargo floor while preserving usable luggage space.

This allows users to enjoy substantial bass upgrades without compromising practicality or vehicle aesthetics.

Advanced Acoustic Performance

The combination of a larger woofer, optimized enclosure structure, and higher amplifier power enables the WB11 to deliver bass that is deeper, stronger, and more impactful than the WB9 and WB10.

Performance Highlights

The WB11 is designed for listeners who want more than simple bass reinforcement.

It delivers a greater sense of scale, energy, and authority, helping reproduce the full impact of modern music, live recordings, movie soundtracks, and dynamic musical performances.

Kick drums hit harder, bass notes extend deeper, and the entire system benefits from a stronger and more convincing low-frequency foundation.

Maximum Bass Without Losing Space

Traditional high-performance subwoofer systems often require large enclosures that occupy significant cargo space.

The WB11 provides an elegant alternative by utilizing the spare tire compartment, allowing users to enjoy powerful bass performance while maintaining a clean installation and preserving everyday practicality.

For many vehicles, it represents the highest level of bass performance achievable without resorting to a conventional trunk-mounted subwoofer enclosure.
