The Studio 89 loudspeaker has a bolt-through driver fixing to reduce cabinet colouration. Each bolt acts as a rigid brace but also removes the need for conventional driver fixings as well, effectively decoupling the driver and front baffle to eliminate a further source of resonance.
NOTE: Should this bolt become loose over time or has worked loose during transit, then please use the supplied hex key to tighten the bolt back up. This only needs to be a quarter turn after the strain has been taken by the bolt.
