Equipped with a high-performance ceramic magnet driver and a 1400 W Peak Class D amplifier, it delivers up to 133 dB SPL with impressive precision and dynamics.

Outstanding sound performance

The SUB 708-AS MK3 combines power, precision and reliability. Its rear-panel controls (volume, EQ, polarity, crossover frequency) enable rapid adaptation to any environment. Thanks to Bass Motion Control (BMC) technology, it offers deep low-frequency extension while preserving speaker linearity and stability. Unlike traditional high-pass filters, this innovative treatment optimizes phase response and guarantees faithful reproduction, even at very high volumes.

High-power Class D amplifier

The 1400 W Peak (700 W RMS ) integrated amplifier ensures powerful, accurate bass reproduction. Its exceptional energy efficiency eliminates the need for cooling fans, the whole unit resting on a solid aluminum heatsink. The integrated, low-distortion active crossover and advanced limiter guarantee optimum protection and natural signal reproduction, even in extreme conditions. EN62368-1 certified, the SUB 708-AS MK3 offers maximum safety and a lightweight, high-performance power supply.

Intuitive controls and connectors

The rear panel is packed with practical features for sound engineers:

• Crossover selector: 80 Hz / 120 Hz
• Reverse polarity
• Line or high-pass output for flexible configuration

These options make it easy to integrate the subwoofer into a variety of sound systems.

A robust subwoofer designed for touring

Designed to withstand the most demanding conditions, the SUB 708-AS MK3 features a birch plywood cabinet with a scratch-resistant polyurethane coating. Its ergonomic handles and low weight make it easy to transport and stack. The M20 threaded base on the top allows installation of a floor-standing satellite speaker. Its powder-coated metal grille, lined with acoustic foam, provides effective protection against dust and humidity, while front vents enable use even in confined spaces.
