The reference. Studio accuracy, designed for real rooms.
The 8c is a fully active, room-correcting loudspeaker that delivers studio-grade accuracy in any domestic or professional environment. Boundary-compensating design means it works with your room, not against it.
CHF 13'490.00 per pair (8c Home). Incl. Swiss VAT. Contact us to order.
White / Natural Oak
Engineered to deliver accurate sound in real rooms, not just anechoic chambers.
Cardioid radiation pattern at low frequencies reduces room interaction. Place them near walls without bass buildup.
Each driver has its own amplifier and DSP processing. No external amplifier, no passive crossover, no compromise.
Dante/AES67 network input, AES3, USB, and analog. Stream from any source, integrate into any system.
Most speakers fight the room. The 8c works with it. Its cardioid bass pattern means you get accurate low end without excessive treatment - whether placed near walls or free-standing. Professional in-room calibration is available on request.

Built to sound as good as it looks.
19 mm solid oak side and top panels. Each panel is unique - pairs are carefully matched during production. Oak is a living material that develops character over time.
18 mm birch plywood creates separate compartments for each driver section, maximizing rigidity and acoustic isolation. The result is an inert enclosure - you hear only the drivers.
Injection-moulded, damped ABS front baffle provides a smooth, diffraction-free surface for the waveguide and drivers.
Connect any source. The 8c supports professional and consumer formats.
Purpose-built floor stand designed by Dutch & Dutch. Sand-fillable for resonance dampening. The speaker bolts directly to the stand for a solid, stable platform. Available in matte black.
