As the table shows, the bass manager directs bass frequencies from all channels to one or more subwoofers, not just the content of the low-frequency effects (LFE) channel. However, when there is no subwoofer, the bass manager directs the LFE channel to the main speakers. This is the only time the LFE channel would not be sent to the subwoofer.

All multi-driver speakers (unless they are coaxial) are difficult to measure correctly if the measuring microphone is placed close to the loudspeaker and slightly above or below the optimum axis because the different path length from two drivers producing the same frequency leads to phase cancellation. It is useful to remember that, as a rule ...
A small plastic Harman Kardon powered computer speaker with a bass reflex port. Novak [2] concluded that a bass reflex enclosure can have greater acoustic output for a given amount of distortion, lower total harmonic intermodulation, and transient distortion than a completely closed-box of similar size. Such a resonant system augments the bass ...

The middle speaker is a real loudspeaker. The top and bottom cones are passive radiators. In the same way as a ported loudspeaker, a passive radiator system uses the sound pressure otherwise trapped in the enclosure to excite a resonance that makes it easier for the speaker system to create the deepest pitches (e.g., basslines). The passive ...
