eq_shadimar Posted February 9, 2006 Share Posted February 9, 2006 The large/small 60/80 setting may depend on your processor. Some will only let you get at the desired frequency with a large or small setting. In any case for movies I run all at small with the 80hz crossover. For 2 channel I run large with a 40hz or 60hz crossover depending on the material and source (vinyl or digital). Laters, Jeff Quote Link to comment Share on other sites More sharing options...
BobbyT Posted February 9, 2006 Share Posted February 9, 2006 Before our nice modern processors, I remember tips pointing out that you should crossover 10-15 HZ over the low end of your speakers. With LaScallas Belles I could see 60 working nice. Khorns, maybe 45-50 Hz. I still think 80 is best as that is what most soundtracks use as there standard reference. JM Now with the nice modern processors I hear people say the crossover point should be a full octave above the low end of the speakers. I don't know if this is considered advancement or not.[] Quote Link to comment Share on other sites More sharing options...
MrMcGoo Posted February 10, 2006 Share Posted February 10, 2006 Whether or not you need a full octave above your speaker's low frequency point is a function of the SLOPE of the crossover. For 12 decibels per octave, one full octave is good. If your crossover slope is 36 decibels per octave, then 10-15 Hz above the minimum of the mains is reasonable. All THX crossovers are sloped at 12 decibels per octave. Bill Quote Link to comment Share on other sites More sharing options...
