ULTIMA SUB-15/LE-1
without a high-pass crossover.
CONNECTIONS (Continued)
SUB-15/LE-1 WITHOUT HIGH-PASS CROSSOVER
Revel recommends using both a low-pass and high-pass crossover
with any “main” left and right loudspeakers. The FM-2 module is
designed to be transparent when inserted in the main signal path.
The use of a high-pass crossover greatly reduces distortion, increases
dynamic range, and optimizes the transition from the ULTIMA
SUB-15 to the main loudspeakers. Your Revel dealer can help with
the proper FM-2 settings. 
If the ULTIMA SUB-15/LE-1 will be used without a high-pass
crossover (see Figure 13), contact your Revel dealer for help in 
setting the FM-2 low-pass crossover so the main speakers and the
ULTIMA SUB-15(s) will produce an optimum combined response.
