Placement

The Boundary Effect

With their compact dimensions, the Niles SW8 and SW6.5 subwoofers provide a wide range of placement options, including wall or ceiling mounting via an optional mount kit.

When considering where to place a subwoofer in a particular space, note that the “boundary effect” can provide increased acoustic output due to the reinforcement effects when the subwoofer is placed on the floor, by a wall or in a corner.

Generally, when placed in or near a corner, the acoustic output of the subwoofer is substantially greater due to the boundary effect’s acoustic gain. This provides two benefits. First, as the acoustic output of the sub (as perceived at the prime listening position) is greater than in free-space (away from the walls, floor and ceiling), the subwoofer doesn’t need to “work” as hard, which results

in lower distortion. Second, the gain provided by the boundary effect serves to increase the subwoofer’s available dynamic range, for increased deep bass output at elevated listening levels.

Generally, corner placement provides the greatest acoustic reinforcement. However, corner placement is not always optimum, and some experimentation may be necessary in any particular room.

If the subwoofer is placed far away from the main speakers, there may be an audible discontinuity between the low bass sound from the sub and the wider upper range sound from the main speakers. This becomes even more critical when using compact main speakers, where a higher crossover frequency is often necessary. At a high crossover frequency (150 Hz), there is a much greater chance of audible main speakers and subwoofer discontinuity, with the subwoofer’s output becoming distinctly audible as a sound source.

Ideally, the best subwoofer placement in any given space will reward the listener with a high quality full range acoustic experience, with the subwoofer itself seamlessly blending in with the main speakers, and not audible as a sound source itself.
