Yes lopass is a crossover. When it's a low pass if you set it at 100hz it will play all hz starting at 100 and below. You can look at your subwoofer frequency range and set filter according. Example if your sub plays 20hz - 125hz, set lp filter at 125hz so it'll play the whole range the subwoofer is capable of. The high-pass is opposite used for speakers/tweeters. Set at 125hz it'll play 125hZ and up. High pass allows high frequency. Low pass allows low frequency.Hello.

This is not the way to properly set any crossover point and most often will lead to undesirable results. In fact, most subwoofers have a much broader frequency range than the example above. In every system I've installed, I've never set a low pass filter for any subwoofers that high. Most often it's been near or below 80Hz. High pass and low pass filters allow frequencies above and below the crossover point to pass without attenuation respectfully. The degree of attenuation per octave (aka slope) varies (6dB, 12dB, 18dB, ...90dB, etc). Subsonic filters (which are also high pass filters) are often used as well as low pass filters for subwoofers in ported enclosures where the high pass filter may be set at or above 20Hz depending on the set up and tuned port frequency, typically around 1/2 octave below the tuned port frequency. the12volt • Support the12volt.com

Yeah my example is in lament terms so you can grasp the concept. But with speakers for example you don't want to get your high-pass as low as the freq response, asking for a blown speaker. But as a concept that's how it worksHello.

Thx i really appreciate all the help this site is greatSeth

whitemike0110, this is inaccurate information.

It's incorrect to keep frequency range in mind when setting crossovers?Hello.

No, not at all. You should, but your statement above is incorrect. Example: You have a subwoofer with a frequency response of 24-200Hz in a ported enclosure that is tuned to 40Hz. You might set your subsonic filter (which is a high pass filter) to 30Hz and your low pass filter to 80Hz. the12volt • Support the12volt.com

crossovers have three basic functions, they keep harmful frequencies from damaging the speaker, they keep your speakers from playing useless frequencies that are beyond the actual audible frequency response, and they help you blend your whole system together. what i mean by that is the same as what THE12VOLT said in the example with the sub and ported box situation. the box that you install the subs in will always limit the audible frequency response even if the sub's specs say it plays up to a certain frequency. so if you know that the sub woofer box only allows the sub to play a certain bandwidth, lets say 30 - 120HZ at an audible level, then anything above or below that is just wasting your amps energy by making it try to produce frequencies that you either wont hear or will damage the speaker. there is really no right way to set your crossover but there are wrong ways. understanding the actual audible responses of your speakers and setting your crossovers with that knowledge in mind can mean the difference between bad sound and great sound even with average speakers.

Thanks for your correction yeah your knowledge goes much deeper than mine I'm only on the surface. I was trying to lay out the basics of a crossover for him like a low pass allows low frequencies and high pass allows highs. he wasn't sure what a crossover was. thanks for your input and knowledge!Hello.
