cabinet bracket installation
Your HT300 or HT400LCR bookshelf speakers are provided with a unique cabinet bracket assembly that
allows the speaker to be mounted using universal or custom-fabricated brackets. Because of the weight
of the HT300/400LCR, these cabinet brackets must be installed carefully and according to the supplied
instructions and diagrams in order prevent risk of personal injury or property damage. Please study the
diagram showing the correct orientation for the cabinet brackets prior to beginning the assembly and
mounting process.
Note: the cabinet brackets only work correctly when installed as shown. Failure to install the
cabinet bracket correctly may result in the speaker cabinet falling.
Determine the correct location for the cabinet bracket on the rear cabinet surface that is required for the
specific installation.
Note: it is generally better to keep the bracket located more towards the center of the cabinet
as the suspended weight is more evenly distributed.
Insert the bolt or other mounting hardware that will be used to fasten the cabinet bracket to the
mounting bracket or arm. Make sure the bolt or securing hardware is tightened prior to placing the
cabinet bracket in place against the rear panel of the HT speaker cabinet. Secure the bracket to the
cabinet as shown using the supplied set screws, making sure the bracket rotates completely under the
slotted edge of the rear cabinet.
Note: the set screws must line up and engage the small slot on either vertical side of the rear
cabinet panel. Failure to properly locate the bracket and secure these screws correctly may
cause the cabinet bracket assembly to separate from the cabinet, allowing it to fall.
Once the bracket and set screws are properly positioned, tighten the set screws to lock the bracket in
position. Make sure the set screws stay locked in the cabinet grooves as they are tightened.
speaker placement
Where you locate the speakers in the room plays a vital role in the sound quality you will enjoy.
Since every room is a little different, you should experiment with various locations to see which
gives the best sound in your particular application. Here are some general guidelines to help you
select appropriate locations
In general, your speakers will have the smoothest response and best imaging when located at
least two to four feet from the back and side walls in the listening room. Moving a speaker closer
to one or more of the boundaries will increase the bass output. In some rooms, the extra bass
may sound good while in others it may cause the bass to sound too strong.
Hard surfaces near a speaker can affect the distribution of high frequencies. Think of a hard wall
as if it is a mirror. Just as a mirror will reflect a nearby object so that you see a second "virtual"
object, a hard wall will reflect sound so that you hear a second "virtual" source of the sound. If
the reflected sound is strong enough it will confuse the imaging of the system. If the speakers
are placed near side walls, try toeing the speakers towards the center of the room. Drapes or
cloth hangings on nearby walls will help to cut down undesired reflections. Drapes are
particularly helpful if the speaker is adjacent to windows or glass doors.
center channel
The HT400LCR when positioned on its side, and placed in the optional HT base, functions as an
accurate and exceptional center channel speaker. The HT400LCR may be placed either above or
below the video monitor when using a direct view or rear projection set. The base of the HT
series allows the speaker to be tilted up or down, simply place the speaker on the base in the
desired orientation. The HT400LCR may also be used without the base by positioning it vertically,
which is the recommended orientation for optimum horizontal dispersion. With front projection
video monitors, the center channel is commonly placed below the screen. Alternatively, by using
an acoustically transparent perforated screen it may be placed in a vertical orientation, directly
behind the screen for optimum imaging.
