A crossover simply filters out a certain frequency range of the signal which passes through it. A high pass crossover filters all of the low and mid ranged frequency of the signal, allowing only the higher end of the signal to pass. A low pass crossover allows only the low end of the frequency to pass. These are usefull for blocking unnecesarry signal to speakers, such as treble and midrange to subwoofers or bass to tweeters. Most likely your crossover is a low pass. You want to adjust this setting in order to make your subwoofers highest frequency response match your other speakers lowest. eg. if your subwoofers maximum frequency response was 120Hz then you want to set your speakers crossover to about 100-120Hz. Just try to make sure there are no gaps or overlaps in the frequency response. This just helps ensure the cleanest and most accurate sound from your system. |

Most bass management low/hi pass filters in Dolby Digital and DTS systems have the cutoff at 80Hz. Above 100Hz, the subwoofer would sound more boomy and the sound from it would be more directional, which is undesirable. |

Unregistered guest | Hi audio monstiz: If I don't get my two rear "Onkyo" surround speakers to kick in with an older Onkyo HTR-500 soon, I'm going to get my head kicked-in instead. I thought is was all hooked up right. I can't get the center speaker to work either. OK, who's gonna save the day? Thankin' all of you in advance, I just need one of ya who knows more than me. Sincerely, Kickin' Soonly |

What I like to do now is add some more active X-over units for the left and right and the side surrounds centre back and then height surround and with careful setting-up this should present a whole new approach in home cinema as very few of you would take this option. Yes I know it's not cheep but if you look around you can find PA stores sealing active X-over units cheaply and a lot of duel stereo amplifiers are also going to be needed EQ's as well and maybe some compressor limiters too top this all off! Now then, the B-chain rules ok. |
