A better way of driving the passive subwoofer is with an electronic crossover and separate power amplifier. This method separates the bass from the signal driving the main loudspeakers at line level, which is much less harmful to the signal than speaker-level filtering.Jul 15, 2015
How does a passive subwoofer work?
A subwoofer (sub) is speaker, that is dedicated to the reproduction of low-pitched audio frequencies most commonly referred to as bass. Passive Sub: Passive subs are called passive because they need to be powered by an external amplifier or Audio/Video (A/V) receiver . This is similar to traditional speakers.

To do so connect the passive subwoofer to the external amplifier and connect the AV receiver/amplifier to the input of the external amplifier. Here you should use the Subwoofer PRE OUT socket on the A/V receiver/amplifier and connect this to the input of the external amplifier.
How do you power a passive subwoofer without an amp?
Type of source component. If you don't have an external amp, then consider connecting passive speakers to a powered source component. This means that the source component should have a built-in amplifier such as a powered mixer, powered subwoofer, or an AV receiver that has a built-in amp.

Do I need a crossover for passive sub?
You only need a passive crossover if the speaker is a 2 or more way parallel system to isolate individual component frequency response range (tweeter, midrange & sub). If it's a standalone subwoofer unit, it should be wired to subwoofer out of your power amplifier.
Are passive subwoofers better?
The passive subwoofer is generally a better bet if you're going to be using it in a small room, where space is a concern and where you don't need a more powerful sound. The passive subwoofer is usually smaller and less bulky than the active subwoofer, although it produces a less intense sound.
How do I connect passive subwoofer to receiver?
You can connect a passive subwoofer to an AV receiver by treating it as a loudspeaker and linking the subwoofer directly to your AV receiver via the speaker connectors. You can also power it with an external amplifier and treat it as a powered subwoofer that connects to the pre-out.
Can a powered speaker power a passive sub?
You can combine and connect passive speakers with powered speakers using the standard connection (Red/Black) or bi-wiring using the appropriate twin cables. Powered speakers consume a lot of power, so people often hook up passive speakers to powered speakers to ensure that they don't overwhelm the power supply.
