Grimm Audio LS1a Active Loudspeakers
“The LS1a possesses all the essential qualities and therefore performs at a true reference level in all key areas.”
The LS1a offers our LS1 series quality at a reduced price. All LS1’s embody our vision that ultimate sonic transparency can only be reached by integrating all components of the playback chain into one system. Only then, we have full control over the interaction of electronics, loudspeaker units and the acoustic behaviour of the cabinet. Grimm Audio’s deep knowledge about circuit design and component choice can then be optimally exploited.
Compared to the standard LS1, the LS1a has a non-magnesium woofer, a lighter foot plate, a lacquered cabinet, plus we 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.
