5 LFO Programming Software
User Guide
When using only a single subwoofer we strongly suggest performing the measurements described in Measuring a Surround-Sound System's Low-
Frequency Response In Your Listening Room, on page 8, with the subwoofer in each of the room’s corners to fi nd the corner that produces the most
consistent results at the various listening positions in your room..
Since wall construction is almost never perfectly identical on opposite walls, common formulas such as placing subwoofers at 1/4 points rarely work in
practice. The best solution is to make high-resolution measurements from the primary listening area while experimenting with subwoofer placement.
