Revel F30 - Manual (Page 9)

• For best results, make sure there are no objects between the
REVEL PERFORMA F30 loudspeakers and the intended listen-
ing area (e.g., a coffee table in front of the listener will degrade
timbre and imaging). If possible, avoid placing the loudspeakers
near large objects, which can cause unwanted reflections.
• Ideally, the listening room should be acoustically neutral, nei-
ther producing any distinct echoes nor sounding completely
“dead” and lifeless (also see Room Treatment on the next page).
• After choosing a final placement, add the spikes (and covers, if
desired) as described in Installing Spikes on page 11.
ROOM ACOUSTICS
Listening rooms have a profound impact on sound quality, espe-
cially at low frequencies. In fact, a listening room can actually
dominate the sound quality below about 300 Hz. Ideally, a new
room being built from scratch would include optimized dimen-
sional ratios to minimize the effects of standing waves.
However, most installations will be made in existing rooms. In
these cases, your only solution is to take special care in selecting
both the speaker and prime listening locations, which will pay off
in superior low frequency performance. Often the difference
between poor and excellent results is the result of relatively small
adjustments in speaker and listener placements.
The interaction of loudspeakers and rooms is quite complex, as the
loudspeaker and listener are affected by two mechanisms. First,
nearby surfaces, or boundaries, cause large peaks and dips in low
frequency response. These peaks and dips can often range 12 dB or
more. Second, the loudspeaker and listener locations interact with
the standing waves, or room modes. These standing waves, or reso-
nances, also result in large response errors. There are no simple for-
mulas that take both mechanisms into account. Even computer
programs that analyze one or both factors still may not provide
you with the proper speaker or listener placement values.
Here’s where real-world experience counts. We suggest consulting
your Revel dealer for help in determining the optimum loudspeak-
er and listener placement for your listening room.
