The Infinity Beta™Series of loudspeakers continues Infinity’s longstanding
commitment to accurate sound reproduction.Our patented Ceramic
Metal Matrix Diaphragm (CMMD

™

) drivers, precision dividing networks,
and rigid, well-braced enclosures, along with our newly developed, patent­pending Constant Acoustical Impedance

™

(CAI™) waveguide,combine to
deliver uncompromised performance in any stereo or multichannel home
theater system. In addition, Beta Series speakers are magnetically shielded
for safe placement adjacent to a television.

UNPACKING THE SPEAKERS

If you suspect damage from transit, report it immediately to your dealer.
Keep the shipping carton and packing materials for future use.

PLACEMENT

Stereo

Before deciding where to place your Beta speakers, survey your room
and think about placement, keeping the following points in mind, using
Figure 1 as a guide:

• For best results, place the speakers 6'– 8' (1.5m–2.5m) apart.

• Position each speaker so that the tweeter is approximately at ear level.

• Generally, bass output will increase as the speaker is moved closer to a

wall or corner.

• Refer to “Home Theater” below if you also plan to use the speakers for

home theater reproduction.

Home Theater

For front-channel use, place one speaker on the left and another on the
right, along either side of the television monitor.Since the speakers are
magnetically shielded, you can place them near the TV without worrying
about the field distorting the TV picture.

For surround-channel use, place speakers on bookshelves or stands
alongside the listening position. Final placement depends on room
acoustics, availability of space and your listening preference
(Figures 2 and 3).

In 6- or 7-channel configurations, place the rear channel(s) behind the
listening position, as shown in Figures 2 and 3.

NOTE: An Infinity powered subwoofer will add impact and realism to both
music and film soundtracks. Contact your Infinity dealer for recommenda­tions on subwoofer models for your application.

bass level and stereo imaging in your room.

Figure 2.This overhead view shows a typical home theater plan.
Left/right rear channels are for a 7-channel system. Center
rear channel is for a 6-channel system.

Figure 3.This figure shows an alternate layout, which may be
more suitable for some rooms. Left/right rear channels are for a
7-channel system. Center rear channel is for a 6-channel system.

INSTALLING FEET

Beta 40 and Beta 50

These models feature four rubber feet, which enables them to be placed
on a smooth-surfaced floor, such as tile or hardwood. Four metal spikes
are supplied for use when the speaker is to be placed on a carpeted sur­face, to decouple the speaker from the floor and prevent unwanted damp­ing.To insert the spikes, gently lay the speaker on its side (not its front or
back) on a soft, nonabrasive surface. Each spike screws into the threaded
insert in the center of each rubber foot. Make sure all four spikes are
screwed in completely for stability.

NEVER

drag the speaker to move it,as this will damage the spikes, the
feet and/or the wood cabinet itself.Always lift the speaker and carry it to
its new location.

CAUTION: Floorstanding (tower) loudspeakers have a high center of
gravity and may become unstable and tip over during earthquakes, or
if rocked, tipped or improperly positioned. If this is a concern, these
speakers should be anchored to the wall behind them, using the same
procedures and hardware customary for anchoring bookcases and wall
units.The customer is responsible for proper installation and proper
selection of hardware.
