About the Graham Audio Chartwell Sub 6
Designed by Derek Hughes and hand-built using Graham Audio’s signature thin-wall, damped cabinet construction, the Chartwell Sub 6 is sold in matched pairs to complement LS3/5 and LS3/5a loudspeakers. Available exclusively in black – a finish that blends effortlessly with any system – each enclosure is meticulously tuned to extend low-frequency performance without compromising the clarity and natural balance that these classic monitors are known for.
Front-facing reflex ports deliver tight, articulate bass that integrates seamlessly with your main speakers, adding scale, depth and authority to your music. With the Sub 6 handling the most demanding low-end content, your LS3/5 or LS3/5a can perform with greater ease and refinement across the rest of the frequency range.

Frequently Asked Questions
Does the sub require a separate amp?
No – it’s passive. You connect your existing amp to the subs, then feed your main speakers, keeping cabling clean and straightforward.
Where should I place the Sub 6?
Ideally directly under your LS3/5 or LS3/5a, using the included feet or optional spikes. The front port allows flexibility in tight setups.
Will the extra bass harm my nearfield listening?
The Sub 6 is designed for musical extension, not boom. If placement causes bass buildup, you can adjust toe-in or move them further away from the wall.
Does the Sub 6 allow me to play my LS3/5 or LS3/5A at higher volume levels?
Yes. By crossing over at 120 Hz, the Sub 6 takes the most demanding low-frequency work away from your LS3/5 or LS3/5A. This not only extends bass performance but also frees the midrange to sound cleaner and more dynamic, allowing higher playback levels without strain.
