  • Grimm's flagship product LS1be takes the LS1 performance to the next level. Their aim was to improve transparency even further by focussing on “authority, control and flow”. To achieve this they worked on lowering distortion and extending the linear audio band. Grimm added a new Beryllium tweeter, which was co-developed with Seas. It extends the frequency range and has 9 dB less distortion than our original tweeter. Furthermore they lowered jitter, improved the power supplies, employed some exclusive component selection and decided on silver power supply wiring for the finishing touch.

    At the low end of the frequency spectrum, they obtained an even bigger improvement. Grimm's newly developed Digital Motional Feedback (DMF) subwoofer has an impressive 30 dB lower distortion, which means the bass area is now just as transparent as the mid and treble.

    Of course, just like with other LS1’s, the LS1be frequency response is linearized through smart use of DSP via a Computer Aided Calibration process during production.

    The LS1be is accompanied by the LS1r controller and the LS1i USB interface, well known from the LS1. The cabinet can be ordered in a stylish ‘Hi-Macs’ artificial stone finish, in traditional bamboo veneer look or in ‘all black’.

    There are many USB audio interfaces on the market but few of them are designed with both the sound quality and the specific use case in mind.

    The Grimm Audio UC1 is a mid price USB interface and monitor controller that has a different approach. It is an ideal match with the Grimm Audio LS1 or PMC monitoring systems, and works great with other active loudspeakers too.


    With the MU1, Grimm's goal was to set a new benchmark in music player design. The Linux-based computer system brings solid data integrity. In-house-designed FPGA interface board, which forms the heart of the MU1, offers breakthrough performance levels in format conversion and receives automatic updates whenever they have pushed the boundaries again. Needless to say, the MU1 features Grimm's trademark ultra-low jitter clock. This is a music player worthy of the name Grimm Audio.

    SB1 with ‘DMF’ is a technological marvel. By applying ‘Digital Motional Feedback’, a control technology from the renowned Dutch high-tech industry, it became possible to achieve exceptionally low levels of distortion and full dynamic control. With an SB1 added for the bass frequencies, the LS1 system offers low distortion over the full audio band and redefines the term ‘transparency’. This is bass control like you’ve never experienced before.

    A pair of
    LS1s stereo subwoofers integrate seamlessly with the LS1 or LS1a. Its phase corrected crossover at 70 Hz is already build in the LS1, so just adding the subs turns the system into a unique phase coherent three-way system.
