Grimm Audio LS1r remote
The beautifully crafted LS1r remote control is part of the LS1 hifi system. It features volume control, source selection and mute, just with one large dial. Two extra digital audio sources can be connected directly to the remote. When placed at a distance, a regular IR remote may be used for wireless control.
Every set (except the LS1a) also comes with a USB interface that facilitate connection of a Windows or Mac PC. It can be used to play audio from the computer directly into the LS1. Mac’s have native support, PC’s require a special driver. Via the same USB connection, the LS1 remote software can be used to setup the system.
An LS1i can also be used as generic USB audio interface by people that need a high performance two channel digital audio interface.

At frequencies below 100 Hz loudspeaker drivers need to move a vast amount of air and therefore have high excursion levels, while also the fundamental resonance – which is present in any loudspeaker – induces unwanted delayed effects. The result is that all conventional loudspeakers exhibit a rising distortion in the bass region with additional “thickening” of the bass by the resonance.
In electronics, feedback is used to minimise distortion. To apply feedback in electro-mechanical systems like an active loudspeaker, an acceleration sensor needs to be mounted on the cone to monitor its motions. This so called “Motional Feedback” technology has been presented a few times before in history but the precision and control as found in the Grimm Audio SB1 is unique. By adding smart digital processing and current drive, the low distortion of the already high-performance aluminium woofer is further reduced by as much as 30 dB, solving all problems that are related to low frequency resonances and distortion.
The SB1 sub is a perfect partner for the LS1v2 and an excellent match for the LS1be. It is even a smart extension for the LS1a. A switch facilitates use of the SB1 with third party systems, so the virtues of Digital Motional Feedback can be enjoyed by many.
