Revel Sub 30 - Manual (Page 23)

Figure 13. Typical corner
placement of a REVEL
ULTIMA SUB 30 in an
average room.
NOTE: Another placement
choice is mid-way along one of
the walls with the front wall
being the most convenient (see
alternate placement).
Simply use the Revel LFO test signals disc, and the LOW
FREQUENCY OPTIMIZER will plot the results of the measure-
ment at each speaker or listener (microphone) location.
The REVEL LOW FREQUENCY OPTIMIZER provides a
convenient way to save each set of measurements and to make
notes so that the effect of various locations can be compared.
Other sound measurement systems may also be used to help
determine speaker and listener locations, as long as the selected
equipment provides at least one-tenth -octave resolution at 20 Hz.
GENERAL PLACEMENT GUIDELINES
• As a general rule, placing a subwoofer in the corner of a room
(see Figure 13 below) will result in the maximum number of
“peaks” and minimum number of “dips” in the response. Most
dips cannot be equalized, but they can be minimized through
optimum placement of subwoofer(s) and the listening position.
The resulting peaks can be corrected through the use of our
powerful built-in parametric equalization.
• Due to the nature of room acoustics, experiment with different
listening location(s), as well as loudspeaker locations, to obtain
the best sound at low frequencies.
