Cut-off frequencies

Matching the frequency responses of subwoofer and speakers has an important impact on the overall sound quality, when integrating a subwoofer into a audio-video- system. In general a large, floor-standing speaker still has significant output in the deeper bass range, whereas a very small speaker will not be able to reproduce deep bass at all. In the first case a bump in the overlapping area will cause a louder or even bloated sound while in the second case an acoustic hole will be experienced.

The following figures visualize the possible results (please note that all curves are for illustration purposes and do not show exact filter characteristics).

Cross-over frequencies set correctly

Subwoofer and main speakers are perfectly matched, when the combined frequency response is smooth without bumps and gaps. A neutral sound will be the result.

Subwoofer too low, main speakers too high

A gap in the frequency response occurs, if the cut-off frequency of the subwoofer is set too low and of the main speakers too high (or if the main speakers are not able to reproduce low frequencies accordingly). In this acoustic hole you will miss some signal information and experience a thin bass sound.

In the other case you will experience unnatural and bloated bass sound, if the

 

 

overlapping area is too large. The combined frequency response shows a bump, as

 

the sound pressure levels in this area are increased.
