C10 Arc Speaker Enclosure

Arc-shaped speaker enclosure for the Lii Audio Crystal-10 full-range driver.

3000 US $ per pair

Arc-shaped cabinet, built for sound

The cabinet uses precision multi-layer bending to create a continuous curved form.

This geometry helps reduce internal reflections and standing waves that are common in conventional box enclosures.

Built from 36 mm thick panels and internally reinforced, the enclosure is designed for rigidity, stability and low cabinet coloration.

Rear wave energy is released through multiple rear ports, helping the system deliver bass with weight and clarity without unnecessary muddiness.

Built around the Crystal-10

The C10 Arc is a high-efficiency full-range speaker built around the Lii Audio Crystal-10 driver.

Its curved enclosure is not only a visual choice. It is designed to reduce internal standing waves, control resonance and support a more open, natural presentation.

The result is a speaker that combines the coherence of a full-range system with the scale and bass support of a large enclosure.

The Crystal-10 driver

At the center of the system is the Lii Audio Crystal-10, a 10-inch full-range driver from our Crystal series.

With a low resonant frequency of 33 Hz and a large 190-liter cabinet volume, the driver is able to deliver deep, articulate bass while preserving the directness, tone and coherence that make full-range listening so engaging.

This is a speaker built for listeners who value presence, tonal continuity and a more natural connection to the music.

Designed for high-efficiency systems

With a sensitivity of 99–100 dB, the C10 Arc works especially well with low-wattage tube amplifiers and other simple, high-efficiency systems.

Its high sensitivity and full-range design help deliver an open, responsive sound with excellent presence, even with modest amplifier power.

The result is an effortless, spacious and highly engaging presentation, with the directness and coherence that make full-range listening so rewarding.
