The problem comes when you try to connect a subwoofer to a signal without a crossover – it sounds terrible! In order to produce clean-sounding bass without vocals or other sounds a subwoofer can’t properly produce, a low-pass crossover is used. The subwoofer works by resting inside of a speaker enclosure where bass frequencies are captured as the woofer cone movies, producing deep bass sound. It’s wired directly the speaker terminals or through passive bass crossover inside in some cases.

Passive (non-powered) subwoofers are simply a subwoofer speaker inside a bass enclosure.These types are one of the most common and in many cases use an RCA type input jack to connect to the receiver for sound. Powered subwoofers use a low-signal signal that is boosted using a built-in amplifier, power supply, and output only bass using a crossover.Home stereo subwoofers are available in two different types: powered (“active”) and non-powered (“passive”).
