Micca RB42 4-Inch 2-Way Loudspeaker
Thank you for purchasing the Micca RB42
Bookshelf Speaker! This product has been
designed for optimal audio reproduction
performance in a variety of home
entertainment configurations, with accuracy,
clarity, and impact that discerning
audiophiles listen for.
Please take the time to become familiar with
the RB42 and the placement options as
detailed in this manual.
General Recommendations
Height - For stereo listening from a fixed
listening area, the RB42 should ideally be
placed at the ear-level of the listener, with the
listener comfortably situated in the listening
location.
Separation - The distance between a pair of
RB42 speakers should be shorter than the
distance from the speakers to the listener. Tilt
the two speakers inward toward the listener
slightly for best results.
Orientation - The speakers provide the best
results in its normal vertical orientation. When
the speakers are placed much higher or much
lower than the recommended ear-level height,
the speakers can be placed on its side to
provide better off-axis performance in these less
than optimal placements.
Usage-Specific Recommendations
Bookshelf Speakers
When placed on bookshelves, it is important to
keep both speakers at the same height. Avoid
placing the speakers at different heights as this
will degrade the sound. Speaker height should
be selected so that it is as close to ear level as
possible while considering whether listeners will
be seated or standing in the listening area.
Stereo Speaker on Stands
When used with speaker stands, it is important
to select speaker stands that place the speakers
to the ear level of the listener. Do this by
measuring the height of the listener’s ear when
seated in the listening area, and subtracting 6
inches. For example, if the listener’s ear is
measured at 36 inches from the floor when
seated, select speaker stands that are
approximately 30 inches high.
Desktop Near-field Monitor
The RB42 can be used as desktop/near-field
monitor speakers, such as when placed to the
either side of a display or mixing console. If the
RB42 cannot be located near ear level, foam
monitor isolation wedges can be used to slightly
tilt back the speakers and to decouple the
speakers from the desk surface. Be aware that
the RB42 is not shielded and thus should not be
placed in proximity to CRT displays or other
magnetic-sensitive equipment.
Speaker Wire
The RB42 should be connected to the amplifier
with good quality oxygen-free copper speaker
wire for best performance.
