Positioning The Loudspeaker - Rainbow Dream Line SLX 210 Einbauanleitung

Rainbow loudspeakers may be installed in your vehicle in a variety of places. In determining the installation
location the following information should be considered:
Woofers require a large area for optimum sound reproduction. Car doors with a large air cushion between the door
lining and external metal or the rear windshield deck of an auto with a large trunk are ideal locations. In some
vehicles designated speaker locations in the instrument panel, doors, rear sides, and rear windshield deck offer the
necessary minimum area.
The installation location of the tweeter must, as with the woofer, fit freely into the available designated area or in a
newly chosen area, in order that an unencumbered radiation of sound is possible. Before installation, the
mechanical installation possibilities, with consideration given to acoustical expectations, should be reviewed. In
order to find the best placement for the tweeter to achieve optimal sound reproduction, installation should proceed
after installation of the woofer/midrange, as follows:
•
Attach tweeter, over the accompanying crossovers or over a suitable crossover, to the amplifier using long
cables in order to permit a free radius of action at the selected location.
•
Set the system into operation and insert appropriate CD. This selects the volume in such a way that the tweeter
is not overpowered by the mid- and low tone range.
•
Vary position of the tweeter until a vivid and spacious sound is achieved. At the same time, exchange the
polarity of the tweeter, (switch plus/negative connections at the connecting terminals) paying attention to
frontstaging and sound variations. Frontstaging adjusts itself only if the tweeter is not too far from the
midrange and/or woofer. The decision as to the optimal installation location requires patience and must be
accomplished by testing several varieties of music.
•
Mark the determined installation placement and prepare for assembly.
Important: Rear and front windshields strongly reflect the tweeter signal and can make the sound seem shrill
and overpowering. Windshields can, for the purpose of support, be used if desired, however,
normally installation in the windshield proximity should be avoided. Upholstery absorbs high
frequency sounds, making sound reproduction seem flat and dull. Sufficient distance from head
rests, upholstered backrests, and seats is essential.
A fundamental consideration in selecting the installation location is that the individual system loudspeakers
should, for acoustical purposes, be kept as close as possible to one another. When the individual loudspeakers
are placed too far apart, an acoustical void that impairs the intended sound can result.
Important: Review mechanical suitability before beginning installation into the selected location!
Built-in auto parts should not be removed. Take care with window mechanics and door handles
during door removal. Likewise, during rear area installations use care around the gas tank. This
area should in no case be worked on in any way. In general, pay close attention to hidden cables
and lines, which should not be cut or removed. Self installation of the loudspeakers is possible,
however take note in advance of necessary specialized technical information about connections and
interior auto safety mechanics.
The most acoustically favorable installation location is not always mechanically suitable. In this case an
appropriate compromise between optimal sound reproduction and mechanical attachment should be determined.
Door Installation: In order to achieve optimal frontstaging, the tweeters should not be placed too deeply in the
door area. They should be installed, for instance, at shoulder height and as far forward as possible, in the vicinity
of the instrument panel. Suitable installation positions here are the side view mirror area and the upper door lining.
Placing the tweeters on diagonal spacer rings (about 20°) can be tonally advantageous, if thereby the arrangement
is done in such a way that the left tweeter radiates to the right door and/or right seat and the right tweeter radiates
sound toward the left door and/or the left seat. (In order to achieve optimal tweeter placement the scenario
described above should be followed.)
