Press Commentaries
Version: July 2014. Subject to change without prior notice.
‘(…) belongs to the reference class of its kind. It creates a relaxed, open,
neutral and detailed acoustic image which will hardly allow any fatigue
effects to sneak in, with a far superior reproduction of spatiality, low
frequencies and transients than what my reference candidates could
have delivered.’
Studiomagazin/10 2008
‘When I found Lehmann Audio on the internet, my decision was rapidly
made, and the (…) Linear sounds great.’ 2008
With our mounting kit your Linear
Pro mounts quite easily and inconspicuously under a table/mixing desk. A
mounting template is included.
