Introduction
The Advent MARBL II multi-purpose speakers are designed to
deliver accurate and powerful high fidelity sound in exterior and
interior applications. The versatile weather-resistant construction
makes them ideal for temporary or permanent outdoor use. And
the full range of sensitivity and mounting options makes MARBL
II equally at home in your home.
For simplicity, we’ll call your AV receiver, stereo receiver or
amplifier the receiver.
IMPORTANT- Do not remove the grilles from your speakers. There
are no user serviceable parts behind the grille.
Placement Indoors
The Advent MARBL II can be placed horizontally or vertically in
any convenient location in your room - as stereo pairs on either
side of your receiver - as center or surround speakers in home
theater surround sound systems that include a subwoofer in your
computer room to enhance the multi-media experience - or as
remote speakers in a whole house sound system. For installation
ease in wall and ceiling applications, the included Advent
mounting brackets can be used.
You can experiment with various placements, with the knowledge
that room acoustics can produce large apparent differences in the
sound for small changes in placement location. For example,
although the speaker may be located at any height above the
floor, locating the tweeter near ear level or angling the entire
speaker toward ear level, often provides the most realistic
musical imaging.
Another rule to follow is that the amount of bass perceived
increases as you move a speaker closer to intersecting rooms
surfaces (walls, ceiling, floor) and that the highest level of bass
results from placement in a corner at the floor or ceiling.
Placement Outdoors
Note- In some installations, you may find it more convenient to
make the speaker wire connections described below before
placing the speaker in its final location.
The Advent MARBL II has been tested for environmental usage
and is weather resistant. Occasional moisture will not
dramatically affect performance. To increase speaker life, mount
in locations not subject to frequent excessive exposure to water,
sun and extreme weather. the speakers should be allowed to
ventilate and dry after water exposure.
The Advent MARBL II can be placed permanently outdoors for
year-round enjoyment. Popular locations include decks, gazebos,
porches, atriums, backyards, garages, and spa areas. A
particularly practical mounting location is under the eaves of a
building adjacent to an outdoor recreation area.
For temporary placement, place the speakers in positions that
achieve the most satisfying audio performance to your ear.
Speaker Mounting
For ease of installation, the Advent MARBL II includes a remov-
able mounting bracket on each speaker. This bracket features
three sets of mounting holes on three different surfaces allowing
you to mount the speaker horizontally, vertically or at a 45-
degree angle. Once mounted, the bracket allows the Advent
MARBL II to be pivoted to its ideal location. The large thumb
screws (included), when tightened, will hold the selected speaker
position. There is also a hex-headed screw molded into the thumb
screws. This allows for loosening and tightening by hand or with
the help of an allen wrench.
Before attempting the installation, carefully evaluate the
mounting surface, making sure that its composition and
construction are strong enough to support the load safely. If you
are unsure about the type of mounting hardware for your instal-
lation, consult a professional contractor or a knowledgeable hard-
ware store. The MARBL II bracket is suitable only for
attaching the speaker to walls or ceilings constructed of solid
wood, brickwork, concrete, hollow building block or wood studs.
Do not mount the bracket to unreinforced plaster or sheetrock
(gypsum board). Once the bracket is secure, reattach the speaker
using the thumb screws included.
Connecting your Speakers
Speaker Cable- Typical speaker cable has a pair of separate
speaker wires with insulating jackets that are molded together.
We recommend you use 18-gauge speaker wire for hooking your
speakers to your receiver.
Polarity- All speakers in a system must be connected with the
same polarity. Speaker wire is marked for polarity so that you can
identify the individual wires in the molded pair. Polarity is shown
by a color stripe on the insulation, by ridges molded into the
insulation, or by the colors of the wires-one copper and one silver.
See Diagram 1.
Important- Always connect the red (+) terminal on the receiver
to the red (+) terminal on the back of the Advent MARBL II, and
the black (-) terminal on the receiver to the black (-) terminal on
the back of the Advent MARBL II.
