Congratulations on your purchase of the Dayton Audio® B452-AIR speakers.
These subcompact-sized speakers use groundbreaking Air Motion Trans­former (AMT) tweeter technology to reproduce clear, natural high frequency
sound that rivals many more expensive speakers. Please read on to discover
how to get the most from your new speakers.

1) Parts Inventory

The B452-AIR speaker package includes the following items:

• 1 pair of Dayton Audio B452-AIR speakers

• 1 pair of 2-conductor red/black speaker cables

2) Installation Tools

No tools are required for installation of the B452-AIR speakers. Additional
tools and hardware may be required for wall mounting.

3) Speaker Placement

Because of their well-behaved off-axis response and excellent dispersion,
your new Dayton Audio speakers are less critical to position than most loud­speakers. Often, simply placing them where they best fit into the decorating
scheme is all that is necessary for exceptional performance. The B452-AIR
speakers feature a wall hanger on the rear of the enclosure to facilitate safe
wall mounting.

CAUTION: The B452-AIR speakers are compact in size, but substantial in

weight. When wall-mounting or shelf-mounting the B452-AIR speakers, be
sure that the wall hanger or shelf is anchored to the structure of the building via
a stud or drywall insert, to prevent falling of the loudspeakers and potential injury.

If you are inclined to go through a more rigorous positioning exercise, the
following paragraphs will help you achieve all the performance that your
system is capable of.

Carefully select a few recordings. Choose recordings made with simple ar­rangements and strong vocals by a single performer. Physically small sound
sources localize much more precisely. Placement of horns, strings, vocals, and
drums will snap into focus when the loudspeakers are optimally positioned.

Start with the speakers directly in front of your primary listening position. Avoid
hard vertical edges within 3 or 4 feet of either side of the cabinet. Position
the cabinets about 1-2 feet out from the wall. Listen to one of the selected
recordings paying close attention to the positions of the instruments and
vocalist. Move the speakers a few inches at a time, returning to the listening
position to evaluate the results. Once placement is optimized, the vocalist will

be firmly positioned in front of the instruments and the instruments will seem
to be between or behind the loudspeakers. If possible, position your speakers
so that when you are seated in the primary listening position your ears are
10-12 feet from the tweeter. Viewed from your seat, the angle between the
speakers should be 30 to 60 degrees.

Pay special attention to the bass. The relation between bass response and
room position is critical. Adjust the position of the speakers closer to or further
away from walls so that the bass levels are in proportion with the rest of the
musical spectrum.

Loudspeaker positioning can be time-consuming, but the rewards justify the effort.

4) Speaker Connection

Use the supplied speaker wire or other good quality wire for the connection
between your Dayton Audio loudspeakers and the amplifier. For longer runs,
heavier wire should be used. For proper performance the speakers must be
“phased” correctly. To insure proper phasing, connect the red speaker ter­minals to the red amplifier terminals and the black speaker terminals to the
black amplifier terminals. All two-conductor wire is marked in some way to
help you do this. One side will be marked with a colored stripe, a raised rib, or
a different colored conductor. Use the marked side for the “red” connections.

5) Caring For Your Speakers

Clean your speakers by wiping with a damp, lint-free cloth. The finish of your
speakers can be maintained and enhanced by periodic use of a surface
protection such as “ArmorAll”. The grills may be vacuumed, gently tapped,
or brushed to remove dust and debris.

POWER RATING NOTE: Almost any speaker can be used successfully with
almost any amplifier. Conversely, almost any speaker can be damaged by almost
any amplifier-despite either unit’s power rating. The published power rating is
accurate only if the volume level is never set above the point of audible distor­tion. Distortion is an indication that the amplifier or loudspeaker is operating
beyond its design limits, and damage may occur – often within seconds. If you
hear distortion, immediately reduce the volume. The B452-AIR is designed to
be used with stereo equipment rated from 5 to 60 watts and from 4 to 8 ohms.

Dayton Audio loudspeakers are designed to reproduce music and speech
in a home environment at moderate volume levels. When used within their
limits Dayton Audio loudspeakers will provide many years of trouble free
performance.
