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.
