What is low-pass crossover on subwoofer?

Low-pass Crossover: The frequency below which your subwoofer will be working. Above this frequency, your main speakers reproduce frequencies for anything sent to the LFE or sub channel. The low-pass crossover is typically variable from 40Hz to somewhere around 160-200Hz.

What should I set my subwoofer low-pass to?

As a general rule, the Low-Pass Filter should be set at a value approximately equal to (or below) 70% of your main speaker’s lowest frequency response. For example, your speaker’s frequency response goes down to 43Hz. 70% of 43Hz equals 30.1, so you should set the subwoofer’s low pass filter to 30Hz.

How do you set up a low-pass crossover subwoofer?

Look at the back of your subwoofer, then set the low-pass crossover at least 10Hz higher than your main speakers’ range. This range is the starting point when configuring your crossover. If your center speaker can produce 80Hz to 120Hz, then you want your low-pass crossover to be anywhere close to 90Hz.

What does a low pass filter do on a subwoofer?

The low pass filter prevents higher frequencies from being produced than what it is set to. So, if you turn on the low pass filter, you’ll hear lower frequency noises from the subwoofer. It enables the production of additional bass. You can turn on the subwoofer LPF if you want to listen to the bass.

What should subwoofer dB be set at?

75 dB
Most people find that 70 or 75 dB on your SPL meter at your listening seat is a comfortable playback level. While 85 dB SPL is often used for THX movie theaters, that level is simply too loud for most listeners with test signals in the confines of an average-sized home theater or living room.

When should I use a low-pass filter?

A low-pass filter can be used very effectively to mimic the sensation that one signal is further away from the listener than another (unfiltered) signal. This technique can be used very quickly, and easily to establish spatial contrast between two signals, especially if they’re separated in the stereo field.

Should I use HPF or LPF for subwoofer?

For example, LPF (sometimes referred to as LP) refers to Low Pass Frequencies and is used for subwoofers designed to play only the lowest notes. HPF (sometimes referred to as HP) refers to High Pass Frequencies and is used for speakers and tweeters.
