Cabinet

Cabinet Cabinet Cabinet
The wooden cabinet is painted using a standard RAL color. An appropriately colored pen can be used to touch up
the paintwork if it is scratched during transport or use. The following RAL numbers correspond to K+H standard
cabinet colors.
Rubber feet reduce the risk of scratching the cabinet and provide some mechanical isolation from the floor.
The acoustical axis is a line normal to the subwoofer's front panel along which the microphone was placed when
tuning the subwoofer's crossover during design. For subwoofers in the Klein + Hummel range, the acoustical axis
is located on the mid-point of the driver(s).
However, subwoofer's can be considered to be omni-directional in their typical pass band as the generated
wavelength is long compared to the object producing the sound, therefore it does not matter in which direction
the subwoofer is pointing when placed in the listening environment.

As the electronics back panel does not seal the enclosure, it can be remote mounted using the REK 2 and DC nn
accessories. If the cabinet is to be flush mounted, care should be taken to ensure that there is adequate
ventilation for the electronics. Although no damage will result, insufficient cooling will cause the amplifier
protection to activate prematurely thereby limiting the system's maximum output level.

Klein + Hummel loudspeakers should only be used indoors and in these ambient conditions:
• +10° C to +40° C (+50° F to +104° F), <90% relative humidity, non-condensing
During transport or storage the ambient conditions can be:
• -25° C to +70° C (-13° F to 158° F), <90% relative humidity, non-condensing
Before connecting the mains power cable, ensure that the correct mains voltage is indicated on the electronics
panel (220-240V or 100-120 V) and that the mains power switch is off. Next connect the input signal cables
(analog or digital as appropriate) and output cables, then power up the loudspeaker. There is a three second
delay before sound can be heard from subwoofer(s) and loudspeakers so as to avoid noises (pops) from
