for less bass output

You can control the loudspeaker’s bass output by placement. This is called the boundary effect. You

will get more bass response by mounting the loudspeaker directly to a wall or other ﬂat surface (any

boundary close to the loudspeaker will reinforce the bass frequencies). You can increase the bass

output even more by mounting the loudspeaker in a corner or under an eave (see Figure 6) This

type of placement gives the loudspeaker two boundaries, thus reinforcing the bass sounds even

more. Of course, if you wish to hear less bass, try moving the loudspeaker away from the boundary

(see Figure 7).

MOUNTING METHODS

The OS loudspeakers can be mounted either horizontally or vertically. The bracket knobs will keep

the loudspeaker angled correctly in any position once they are tightened. You can choose from three

mounting methods to attach the loudspeaker to the wall, ceiling, or other mounting surface.

1. If the loudspeaker is never going to be exposed to sudden accidental impacts, wind,

waves, or earthquakes, you can simply hang it on a nail using the nail hole(s) on the

bracket (see Figure 8 on the next page).

2. The safest and most secure way to mount the loudspeaker is by screwing it to the

mounting surface using your own hardware (suitable for the surface you are mounting

to) and the bracket supplied with the loudspeaker (see Figure 8).

3. There is a threaded brass insert (1/4" – 20) on the back of the OS loudspeakers

for attaching a custom bracket (see Figure 8). This allows you to position the

loudspeaker at unusual angles or varying distances from the mounting surface.
