derrickdj1 Posted March 23, 2013 Share Posted March 23, 2013 I seen an article which has general guideline for selecting the right xo for systems using bass management. Determining The Crossover Setting(s) to Use Several factors need to be taken into consideration when determining the crossover setting. You need to know both the frequency range of the speakers and that of the subwoofer in order to determine the acceptable range of frequencies you can use for the settings. If you buy a speaker package, guidance on what settings to use will more than likely be outlined within the documentation that accompanied the speaker package. In other instances, the following rules apply. The highest frequency a subwoofer is capable of handling is the highest frequency you should use for the crossover settings. The lowest frequency a speaker is able to handle is the lowest you should set its crossover to. EXAMPLE 1 Subwoofer frequency range: 20-130Hz Centre speaker frequency range: 70-20,000Hz Therefore the acceptable crossover settings range for the centre speaker would be: 70-130HzThis means you can use a setting of 70, 80, 90 etc., up to 130Hz for the centre speaker. If you use settings above or below the acceptable range then frequencies outside of the acceptable range will be lost and not reproduced by either the subwoofer or the associated speaker. EXAMPLE 2 Subwoofer frequency range: 35-120Hz Rear speakers frequency range: 120-18,000Hz Therefore the acceptable crossover setting would be: 120HzThe above example gives no leeway for adjustment and a setting of 120Hz must be used for the rear speakers. EXAMPLE 3 Subwoofer frequency range: 24-175Hz Front floorstanders frequency range: 48-20,000Hz Centre speaker frequency range: 75-20,000Hz Rear speakers frequency range: 68-20,000Hz Therefore the acceptable crossover setting ranges would be: Front floorstanders frequency range: 50-170Hz Centre speaker frequency range: 80-170Hz Rear speakers frequency range: 70-170HzSome of the potential settings for the above example could be 70Hz for the front speakers, 100Hz for the centre and 80Hz for the rears.When you know what the acceptable crossover range is, there is no optimum setting that suites all situations and listening tastes. It is up to the individual to determine which setting best accommodates their listening environment and tastes. As far as the settings go, one person's nirvana may be another's hell on earth. http://www.avforums.com/forums/av-amplifiers-receivers/1019893-crossover-speaker-settings-relation-bass-management.html Quote Link to comment Share on other sites More sharing options...
Mongo171 Posted March 23, 2013 Share Posted March 23, 2013 This will definitely help me tune in my sub. Thnx for the info! Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted March 23, 2013 Author Share Posted March 23, 2013 You are welcome. I thought this article made a lot of sense with some solid reasoning behind it. It does make the xo decision a lot easier.[] Quote Link to comment Share on other sites More sharing options...

It is easier to grasp when it is written out. I forgot I can't set individual speaker xo points on my Oppo. I can only set it where the sub can take over from the rest of my speakers. So it is set at 80Hz. Quote Link to comment Share on other sites More sharing options...
