Placement
optimization
While true subwoofers operate at extremely low frequencies which are primarily omni-directional, keep in mind
that frequency response and output level can be dramatically influenced by where you place the subwoofer
within the room. Placing the subwoofer in the wrong location may degrade sound quality, limit low frequency
response and reduce maximum output level, substantially reducing your overall listening pleasure. Finding
the optimal location usually requires some experimentation to determine what sounds best in your room,
from your listening position. We suggest you to read the guidelines below and setup the subwoofer in one
of the suggested locations.
In most rooms, the optimum location for your subwoofer is in the closest solid corner to your listening position
(e.g., without a door or opening nearby - see figure to the left). This location typically offers optimal energy
coupling with the room and the deepest low frequency extension, with the best high impact bass. When using
a pair of subwoofers in stereo, it is preferable to place each subwoofer by the satellite of the same channel,
see figure to the right (2). If you want a more flat frequency response and the bass evenly distributed over a
larger area of listening positions, then four subwoofers, one in each corner is the ultimate option (4).
Proceed to listen to the sound system multiple times, while trying a few different locations before settling on
the final one. To do this, perform basic setup and listen to a familiar music track or movie scene. Then move
the subwoofer to an alternate location & repeat listening to the same music track or movie scene, until you
find the optimal position. If you have a test CD and SPL meter or preferably one of our measurement systems
(Room Analyzer II / II Pro), performing a basic frequency response test can help you determine which location
provides the best frequency response.
