“The LS1a possesses all the essential qualities and therefore performs at a true reference level in all key areas.”
The LS1a possesses all these essential qualities and therefore performs at a true reference level in all key areas. By making some rational choices Grimm Audio was able to offer this quality at a significantly reduced price. Compared to the standard LS1, the LS1a has a non-magnesium woofer, a lighter foot plate, a lacquered cabinet, plus they skipped some of the labor intensive modifications and the individual acoustic calibration of each LS1 cabinet.
What stayed are the low distortion and extremely linear amplitude and phase response (achieved through Computer Aided Calibration during production). And of course the form factor that makes positioning close to a wall possible without wall reflection interference. The LS1a has versatile connections for analog and three digital AES/EBU sources. With the optional USB audio interface, any computer can become your audio source. The LS1r controller allows convenient control of volume and source selection.
An LS1a covers the full frequency range as an elegant two way system. By adding an LS1s or even SB1 subwoofer set, the LS1a becomes a very low distortion three way loudspeaker that can handle all music styles in any size room.
This speaker serves as the ideal reference for artists and music lovers alike.

UC1
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.
MU1
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
The 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.
LS1s
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.
