Do passive subwoofers need a crossover?

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.

What should be the crossover for subwoofer?

80 Hz
The most common crossover frequency recommended (and the THX standard) is 80 Hz. On-wall or Tiny ‘satellite’ speakers: 150-200 Hz. Small center, surround, bookshelf: 100-120 Hz.

What crossover frequency should I use?

The recommended crossover frequency is 56-60 Hz (high pass). At this frequency, low-end bass, which can cause distortion, is filtered out. This crossover is the perfect middle ground between midrange bass capability and full-range sounds.

What is the difference between 80hz and 120hz?

80hz tends to work best in most systems for a variety of reasons. But smaller speakers will often begin to sound strained / harsh much lower than 120hz or even 150hz. These would likely sound best with a crossover much higher than 80hz. If you use low to moderate volume levels 120hz may work adequately.

Is a crossover necessary in car audio?

Why Do You Need A Crossover? Every audio system, including the one in your car, needs a crossover to direct sound to the correct driver. Tweeters, woofers and subs should get high, mid and low frequencies respectively. Every full-range speaker has a crossover network inside.

What phase should my subwoofer be on?

Typically, though, phase is left at 0° for most applications. While seated in your listening sweet spot, play music with bass content that is familiar to you and then have someone switch the 0/180 phase switch on the sub to 180-degrees. This will let you determine if the bass sounds louder in your seating position.

Can you connect a passive subwoofer to an active subwoofer?

You will only need to use one channel of it. You could leave the passive subwoofer connected with the active sub or use just the active sub. Try it both ways to see what your prefer.
