Centre
The centre speaker allows for a more realistic reproduction of dialogue. The centre speaker should have a similar tonal balance to the front left and right speakers and be positioned at a similar height.
L
Subwoofer
A subwoofer will greatly improve the bass performance of your system. This is useful for reproducing special cinema effects, especially where a dedicated LFE (Low Frequency Effects) channel is available, as with many discs encoded with Dolby or DTS technologies.
More than one subwoofer unit may be required for larger installations, particularly in rooms of a timber frame construction. Multiple subwoofers need care in placement because there may be cancellation effects between the units and you may require expert advice.
