About the Acoustic Space Switch<br />
The bass response of a speaker is greatly affected by the<br />
speaker’s proximity to walls. You’ll notice a buildup in<br />
bass frequencies as a speaker moves closer to a wall and<br />
even more buildup as the speaker moves closer to a<br />
corner. This happens because low frequencies radiate in<br />
all directions from the speaker cabinet and are reflected<br />
off your walls back into your control room. When this<br />
happens, the reflected sound mixes with the direct<br />
sound of the speaker itself resulting in “reinforced” bass.<br />
Unlike bass frequencies, midrange<br />
and high frequency sounds are<br />
much more “directional” and only<br />
radiate forward. Because of this,<br />
the Acoustic Space Switch only<br />
deals with bass frequencies—there<br />
is no need for high frequency<br />
compensation near walls.<br />
We know that most home and project studios are set up under less than ideal<br />
conditions, so we’ve added the Acoustic Space Switch to help you optimize your<br />
speakers to your room.<br />
If your speakers are farther than about 3 feet away from the walls of your studio,<br />
leave this switch set to the default “0” setting. This “full space” setting outputs<br />
bass normally.<br />
If the speaker is up against a wall, set the Acoustic Space Switch to “2.” This<br />
setting is known as “half-space” and compensates for boosted bass due to your<br />
speakers being placed near one wall.<br />
Finally, if your speaker is positioned in a corner, set this switch to “4.” This is<br />
known as a “quarter-space” setting and compensates for placement next to two<br />
walls.
