Surround Speakers
Description
The VRX surround speaker delivers the wide frequency response, high power handling and
placement flexibility required by the finest home theater systems. Its unique driver complement creates an enveloping sense of surround sound, simulating the multiple surround
speakers found in a quality movie theater.
The VRX is a high output, wide dispersion surround speaker. It provides the rear channel sur-
®
round sound effects with Dolby
Digital, DTS®and Dolby Pro Logic®decoding electronics.
The VRX may be placed on a shelf or mounted on a wall or ceiling using the supplied template, mounting hardware and bracket. Gold-plated five-way binding posts allow the connection of virtually any speaker cable. Its unique design allows for it to create a seemingly
larger or more intimate acoustic space, depending upon how it is oriented relative to the
listening space.

Direct vs. Diffuse Sound Pattern
The VRX represents a product evolution based upon our considerable experience with direct
and diffuse radiating surround speakers. The surround channels from a movie soundtrack
are designed to help the moviemaker transform the theater into the environment that is
being portrayed on the screen. Since a movie theater is a relatively large space, several surround speakers are placed along the theater’s walls. If you would like your listening room
to sound more like a larger acoustic space such as a movie theater or live music venue, then
the VRX should be placed so that the speakers’ passive radiators acoustically interact with
most of the room. This is accomplished by mounting the speaker so that the diffuse side
arrow on the back of the speaker is aimed toward the listening area. If you prefer the surround effects to be more discrete and localized such as in a small room, then you should
mount the speakers so that the direct side of the arrow on the back of the speaker is aimed
toward the listening area.
Direct Configuration Diffuse Configuration
In either case, the best results will be obtained if the VRX is mounted above ear level and
out at least 20 inches from the corner. However, it has been our experience that satisfactory results can be obtained with a wide variety of placement choices. Experiment between
direct and diffused patterns by simply swapping the right and left speakers.
Mounting Tips
Use the supplied template to aid in positioning the mounting bracket. At least 4 inches of
clearance is required between the top of the template and the ceiling. Please take care that
the mounting brackets are attached securely to the chosen surface. Toggle bolts are supplied for use on drywall or hollow plaster walls. Alternatively, you may wish to obtain wood
screws for wood or wall studs or masonry anchors for masonry walls. Use the supplied selfadhesive rubber feet to place the speakers upright on a shelf.
Setting Up Your Home Theater System
Volume Levels: To obtain the best home theater effect, match the sound levels of each speaker. Home theater systems include a test signal that simplifies this level matching. Refer to the instructions provided with your surround sound electronics.
Bass Management: Set the surround channels to “SMALL.” This setting diverts low bass to the
LFE channel, and will result in the greatest total system bass output. For more information on Bass
Management refer to the instructions provided with your surround sound electronics.
