Paradigm PDR W100 - Manuel (Page 9)

YOUR NEW SUBWOOFER
The ‘Watts’ (W) rating indicated on the back panel of your subwoofer is
the typical AC power the unit will consume when producing its maximum power output. However, the actual wattage consumption will
vary with the bass content of the program material.
POWER REQUIREMENTS
Break-In
Although your Paradigm subwoofer will sound great ‘out of the carton’ it will
sound even better when broken in. Allow it to operate for several hours before
you listen critically.
Cleaning
Do not use a strong or abrasive cleaner on your subwoofer. Clean it with
a damp soft cloth, but do not get it wet. Do not place wet objects, such as
drinking glasses or potted plants, on top of it. If allowed to soak in, even
a small amount of water may permanently damage the enclosure.
You are about to experience the powerful and extremely accurate deep bass
performance of Paradigm subwoofers. They offer incredible output with low
distortion, exceptional extension and superb definition. It is important to
note, however, that just as the amount of soft furnishings has a decided
impact on mid and high frequencies, those frequencies below 150 Hz are
dramatically affected by the room itself—its size, shape, as well as the
physical boundaries of the room. The extra care you take in correctly
positioning your subwoofer(s) will result in greater listening enjoyment. Keep
the following guidelines in mind when deciding on best subwoofer placement: • Concrete floors and walls tend to aggravate low-frequency standing
wave problems and are less preferred.
• Rooms where height, width and length are similar should be avoided as
they can exhibit significant low-frequency standing wave problems. This
may result in reduced clarity. If no other room is possible, experiment
with subwoofer placement to minimize acoustic problems.
ROOM ACOUSTICS
SUBWOOFER PLACEMENT
To avoid personal injury, install subwoofer in a location
where any rear amplifier parts such as panels and/or
heatsinks, etc. cannot be accidentally touched.
Bass is less and less directional as it goes down in frequency. For best sonic
integration, locating your subwoofer between your front speakers or beside
one of them and close to the back wall will usually provide the best bass
performance. If this location is not possible your subwoofer may be placed
anywhere in the room without affecting the stereo image of your front
speakers or the soundstage of your multichannel speaker system.
Fig. 1a and Fig. 1b highlight how bass output is generally affected by room
placement. When seated in a typical listening area of your room, placing the
subwoofer inside the ‘shaded’ areas will typically result in bass performance
as follows:
Fig. 1a: Corner placement provides the most bass, but sometimes at the
expense of accuracy.
Fig. 1b: A subwoofer placed near a wall usually provides a good balance of
quantity and accuracy.
Controls are provided to align your subwoofer’s output with that of the other
speakers in your system, see later section on ‘Fine Tuning.’
Although a single Paradigm subwoofer provides exceptional performance
and substantial output, the quality (and quantity) of bass can be further
improved with the use of two subwoofers (Fig. 2). This allows you to
randomize the standing waves within your listening room so that bass will
be distributed in a more uniform manner. Two subwoofers also provide even
lower distortion, especially at high output levels. Wireless Subwoofers
Keep in mind that when using two wireless PDR-W100 subwoofers, one
wireless transmitter is required per subwoofer.
(See Dealer for connection instructions using multiple subwoofers.)
