GRIMM: LS1C
The LS1c is the flagship of our LS1 active loudspeaker series. It is named after the revolutionary TPCD Carbon Composite tweeter that we developed in cooperation with driver manufacturer Seas. Even more important is that we rebuilt all elements of the LS1 design from the ground up: the electronics with latest generation amplifiers, the audio DSP code, the computer aided calibration method, the firmware and the PC/Mac software that controls the entire system. To pick just one example, with the knowledge we gained from developing the MU1 and MU2 FPGA Pure Nyquist filters, we were able to dramatically improve the crossover phase correction filters of the LS1c’s DSP.
As result, the LS1c offers an incredible level of integration over the full frequency band – a loudspeaker has never sounded so much ‘as one’. Its rendering of the stereo image appears more tactile than ever, its capability for microdynamics exposes unheard details and its extraordinary phase coherency reveals the subtlest rhythmic structures. At the same time the natural, non-fatiguing sound of the LS1c invites one to long listening sessions.
“All elements of the LS1 design were rebuilt from the ground up.”
At the low end of the frequency spectrum, the elegant Digital Motional Feedback SB1 subwoofer offers unparalleled bass. Our unique motion feedback technology lowers the distortion by 30 dB and places the resonance frequency below 20 Hz. Bass has never sounded so detailed and controlled.
A natural companion for the LS1c is the MU1 music player that allows control of all loudspeaker parameters. But an LS1c is equally happy when combined with the LS1r controller and the LS1i USB interface. The cabinet can be ordered in a stylish ‘Hi-Macs’ synthetic stone finish, or in our traditional bamboo veneer or lacquer look.

GRIMM PW1
For many generations, true lovers of sound and music are inspired by vinyl playback. Even in these days of high performance digital audio playback systems it is hard to imagine a future without LP’s. There’s just something magical to it.
Grimm Audio’s co-founder Peter van Willenswaard spent a life time designing and improving phono preamps, both in solid state and with tubes. Of all stages of audio amplification, phono preamplifiers pose the biggest challenges to a designer. With moving coil cartridges, deep bass signals of a mere 50 nV require no less than 90 dB amplification!
“Vintage vinyl taught us that sound can be magical.“
For the PW1 “Phono Wizard”, Peter managed to develop a solid state phono preamplifier that matches his best tube based designs. Peter believes that designing a good phono preamp is not about achieving the lowest possible harmonic distortion as an isolated parameter. He searches for an elegantly minimalistic circuit design in which he optimizes the ‘electric environment’ of all the active components, in conjunction with a meticulously tuned power supply. Needless to say that passive components like capacitors and resistors are carefully picked.
The result is a well balanced design with Peter’s signature sound, that is very spacious, detailed and open, but at the same time rhythmically addictive and emotionally involving.
The industrial design had to justify this quality. Michiel Uylings of MU1 fame matched the sonics with a simple but powerful cabinet shape and Grimm Audio’s design team made the copper shielded interior look like a piece of art. Truly a design for generations to come.
The MU1 has 6 channel outputs and 3 stereo digital audio inputs.
