How Active Subwoofers Work

An active subwoofer receives a low- level (line) signal from your source contrigent - an AV receiver, preamplifier, or audio interface - via an RCA or XLR cable. Thee internal amplifier boosts that signal to drive thee subwoofer condirectly. Most active subwoofers included addistable low- passsor crossour filters, phase controls, gain knobs, and often parametric EQ or DSP presets.

Często Asked Kwestionariusze About Activee vs Passive Subwoofers

Czy mogę połączyć pasję subwoofer to a standard stereo amplifier?

Yes, but you need a separate crossover or bases management system to split the frequencies. Most stereo amplifier have a line- level subwoofer output, but that output is intended for an activite subwoofer.
