The acoustic lens

The awarded active studio monitor is driven by unrivaled
power and precision demanded by pro audio engineers.

Empowers you to perfection

A fast sound transducer, the corresponding power amplifiers and a bass unit for effortless reproduction of even the lowest octaves are just some of the outstanding features of the c1.

Awarded design

The c1 takes gold at the famous international design award
Focus Open.
Design: Stefan Harlé









Designed to perfom in every situation

Other features aren't standard either: firm handles for transporting this 30 kilogram heavyweight, a perfect matching and movable stand that is available in different heights, a dockable bass unit as an optional extra, a self-explanatory operating console with a clear layout and finally an attractive design that is still mindful of the needs of the user.

The studio workhorse

We have thought of various adjustment features to make a sound engineer's life that much easier. These include room adaptation filters, near-field/cinema-screen EQ settings, and an input trimming stage controller that can precisely set the two-channel or multi-channel equality to within a tenth of a decibel.

Lows taken to new heights

The c1 LF-Module is an additional passive woofer module that allows an increase of a 6dB higher max SPL.

Dimensions: (H x W x D) 264 x 270x 343 mm
Weight: 11 kg


Take a stand

We have designed an elegant yet robust stand featuring special decoupling materials at a standard height of 612mm with a beautiful aluminum silver anodized finish. We are happy to deliver custom heights upon your request.

Your individual high end finish

You have full control over the way the c1 looks and fits into your personal environment. Whether you want it dark, light, white or fancy a special tone: we'll be happy to receive your wish and produce your personal and individual c1 for you.

Color options

We offer finishes in satin and high gloss as per RAL or NCS. You can also choose from a broad selection of finest veneers to match your personal taste. Below is just a brief selection:
