Graham SUB 6

Graham SUB 6

Engineered to enhance the LS3/5 experience

Placed directly beneath the main speaker, the Sub 6 expands the low-frequency response, adding warmth and depth to your listening experience. Its compact cabinet houses a front-facing reflex port, allowing for smooth and efficient airflow even in smaller spaces. The result is natural, articulate bass that enhances musical realism.

High-quality passive design

Unlike powered subwoofers, the Chartwell Sub 6 maintains a pure signal path by using a passive crossover network. This setup allows your amplifier to control both the subwoofer and main speakers, preserving coherence across the entire frequency spectrum.

• Custom-designed crossover with air core inductors for zero saturation distortion
• Polypropylene capacitors for improved signal accuracy
• Rear panel inputs and outputs for easy integration with your system
• Front reflex port for optimal bass performance
• Mounting points on the base for feet or spikes, ensuring stability and acoustic isolation

Discreet and functional design

The Sub 6 matches the aesthetic of the LS3/5 and LS3/5A, both in size and finish. Its low-profile design not only supports your main speakers physically but also blends beautifully into your room. Whether you’re listening to classical music, jazz, or film soundtracks, it brings a fuller, more immersive low-end presence to your setup.
