Operation

Positioning possibilities

Moving the subwoofer closer to walls and corners in particular will generally increase the amount of bass. Although the extra amount of bass can be compensated for by reducing the volume level of the subwoofer relative to the rest of the system, this can result in uneven bass response at the listening position. You can try starting with placement in a corner and experiment by gradually moving it out of the corner or further away from the wall. Try to locate the position which yields the best compromise between position, volume and even bass response. Note that every time that you reposition the subwoofer (even if it’s over a short distance) you may need to adjust the level and phase settings again.

Corner placement

This placement yields maximum boost of bass level but potentially uneven distribution of bass in the room (room-modes), particularly if the room is square or shoe-box shaped.

XFrom the listening position, check if the bass is even across the entire bass spectrum. If not, move the subwoofer out of the corner. Try moving it along either wall.

Next to wall, away from corner

This position still provides considerable boost but less than the corner placement as above. Room-modes can also still be considerable but less so than with corner placement.

XFrom the listening position, check if the bass is even across the entire bass spectrum. If not, move the subwoofer away or towards your listening position until the most even response has been obtained.

XAvoid placing the subwoofer exactly half-way or at a quarter of the wall’s length.

Free standing, away from wall and corner

This position will give least boost compared to wall or corner placement, but in general offers the best flexibility at achieving most even bass distribution at the listening position.

XAvoid placing the subwoofer exactly half-way or at a quarter’s length of either sidewall.

XParticularly in smaller square or “shoe-box” shaped rooms the free standing position is recommended.

Using multiple subwoofers

By using carefully positioned multiple subwoofers it is possible to even out the different room-modes and thus create a more coherent overall bass response in the room. It is worth experimenting with different locations around the room for the additional subwoofers, even using the rear of the room. As adding subwoofers will not increase the effect of room-modes, even adding a subwoofer without much care or thought to positioning is likely to help even out room-modes.
