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.

X From 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.

X From 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.

X Avoid 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.

X Avoid placing the subwoofer exactly half-way or at a quarter’s length of either

sidewall.

X Particularly 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.
