Insulating the wall cavity – Niles Audio HDLCR User Manual

INSULATING THE WALL CAVITY

For best performance from your speakers, ﬁll the wall cavity behind the speaker with ﬁberglass
insulation (e.g., R-19 un-batted insulation). Try to keep the same amount of insulation for each
speaker, particularly in the same room, for consistent bass response.

LOUDSPEAKER.

PLACING THE HDLCR AS THE FRONT LEFT AND RIGHT

SPEAKERS

In a home theater, the intelligibility of dialog and action reproduced by the front speakers is
paramount! The position of the speakers plays a very important role in how clear the sound is
and how a stereo image is created. Here are some guidelines to make the process of placement
quick and easy:

• Make sure the sound will not be blocked or reflected off furniture or other objects. The

listener should have a direct line of sight with the front of the speaker. To determine
the best position, measure the “listening” distance between the ideal listening position
(e.g., favorite chair or couch) and the wall in which you plan to install the speakers.

• For stereo music applications, try to place the speakers so that they are equally distant

from the listening spot and at least one half of the listening distance apart to maintain
a large pleasant stereo “image.”

• In home theater applications where there is a center channel, you may choose to

space the left and right main speakers farther apart for a “bigger than life” sound with
Dolby

encoded movies and TV shows. However, for combined music and movie usage,

we recommend using the placement zone for stereo music. Ideally, if the listening
position is 10 feet back from the wall, place the speakers between 5 and 10 feet apart,
as shown in Figure 2.

TECH TIP

Wire size is expressed by its AWG (American

Wire Gauge) number – the lower the number,

the larger the wire. For example, 12 AWG is

physically larger than 14 AWG.
