Placement and Operation

Generally speaking, the best location for your new subwoofer is the front of the room, close to a corner (Figure 5). Every room has its own unique sound characteristics, and flexibility in the exact placement of the subwoofer is always desirable. The closer the subwoofer is placed to a wall and especially a corner, the more and deeper the bass response you will hear.However, in some rooms, corner placement can produce a “one note” boomy effect. Under such circumstances the subwoofer may work better away from the corner. Experiment to find the best position in your room.

Using the Subwoofer Low-Pass Control

produce a cohesive and well integrated sound“picture.”

			Care of Your Subwoofer
			Your subwoofer is constructed from Medium Density Fiberboard.MDF
			is a non-resonant material ideal for speaker system enclosures. To clean
			the cabinet you may use a soft cloth either dry or slightly dampened with
			clean water. Be careful not to wet the cabinet or allow any water to enter
			the cabinet seams.Avoid placing your speakers in direct sunlight or near
			a source of heat that may, over time, damage the finish.
