Congratulations on your purchase of the Dayton Audio

These 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 B652-AIR speaker package includes the following items:

• 1 pair of Dayton Audio B652-AIR speakers

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

2) Installation Tools

No tools are required for installation of the B652-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 B652-AIR speakers feature a

wall hanger on the rear of the enclosure to facilitate safe wall mounting.

CAUTION: The B652-AIR speakers are compact in size, but substantial in

weight. When wall-mounting or shelf-mounting the B652-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.

Back

Front

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 to 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 room boundaries 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 B652-AIR is designed to be used

with stereo equipment rated from 5 to 75 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.
