The Grimm Audio LS1c is the latest flagship active speaker from Grimm Audio, designed to surpass the exceptional performance of its predecessor, the LS1be. This speaker combines advanced technology with a refined design, delivering unparalleled sound quality for both audiophiles and professional studio environments.

The LS1c builds upon the proven LS1 platform, which has guaranteed transparency and precision for over a decade. While the LS1be excelled with its beryllium tweeter and SB1 Digital Motional Feedback subwoofer, the LS1c introduces several key innovations. The most notable change is the replacement of the beryllium tweeter with a TPCD Carbon Composite tweeter, developed in collaboration with SEAS and Composit Sound. This tweeter uses advanced "metamaterial" membrane technology, with carefully controlled layers of carbon fiber that provide exceptionally low distortion and fully controlled resonance. Although the beryllium tweeter of the LS1be was already impressive with 9 dB less distortion than its predecessor, the TPCD tweeter offers similar properties and a wide frequency range, while providing a solution to the discontinued production of beryllium membranes. The tweeter is mounted in a specially designed aluminum waveguide, ensuring seamless integration and maintaining the tight, screwless aesthetic of the LS1be in the Hi-Macs version.

In addition to the new tweeter, the LS1c has been completely modernized. The electronics have been redesigned and are now equipped with the latest generation of Hypex NCore Class-D amplifiers, enabling even more efficient and powerful driving of the speaker units. The firmware has been rebuilt from the ground up, resulting in improved stability and the ability to implement future updates. A new feature is the preparation for a remote-controlled standby mode, something that was not available with the LS1be. These upgrades make the LS1c not only technically more advanced but also future-proof.

The LS1c retains Grimm Audio’s core philosophy: an integrated system where DSP, DA converters, amplifiers, and speakers are perfectly tuned to each other. The frequency response is optimized during production through a Computer-Aided Calibration process, resulting in an extremely linear reproduction. Like the LS1be, the LS1c can be paired with the SB1 subwoofer for powerful and transparent bass reproduction down to 20 Hz, but benefits from the latest DSP and equalizer settings that can also be updated for older LS1 customers free of charge.

In terms of appearance, the LS1c offers the same stylish options as the LS1be, such as the Hi-Macs artificial stone finish or the classic bamboo veneer look. However, the internal design has been refined with a visually appealing copper-shielded structure. In short, the LS1c distinguishes itself from the LS1be through its innovative TPCD tweeter, improved electronics, new firmware, and additional functionalities, all while elevating the legendary sound quality and aesthetics of Grimm Audio to new heights. This makes the LS1c a worthy successor and a state-of-the-art choice for those seeking the best in audio.
