Effortlessly exceptional.
iBox XC

Effortlessly exceptional.

Every XC is cut, shaped, and finished entirely by hand — weeks of work on a single speaker, until the solid bamboo reaches a finish you'll want to run your hand across.

Royal Dutch Soundsystem.

A hand-stitched leather handle. A machined volume dial. A red-LED voltmeter reading the charge down to the volt, and a battery light that glows from inside the bass port.

Sound you hear exactly as it was recorded.

Bamboo at 75 lb/ft³ — nearly twice as dense as oak. Heavy enough to stay still while the drivers work, so what reaches you is the recording. Jazz, classical, a single voice — the weight of the bass, the air around the piano, the breath before the note.
