APPLICATION:

 

BASS MIDRANGE LOUDSPEAKER 310mm (12")
Bass in Studio Monitoring Systems

FEATURES: The RV3143 is a unique loudspeaker. It features two cooling systems. In addition to the conventional rear vented magnet it uses the patented, front mounted, Radial chassis which acts as a giant heatsink. This keeps voice coil and magnet temperatures exceptionally low resulting in superb reliability, 3dB less power compression and tight, clean bass even after prolonged operation at maximum power. By maintaining low voice coil temperature there is less change in the Thiele-Small parameters thus system alignment is better maintained after prolonged high power operation. The RV3113 has a symmetrical field magnet for absolute linearity and transient control on high power peak inputs. Innovative design has produced a breakthrough in performance and reliability.
