Quick question re new sub x-over
Hi, I've just installed 2 brand new (very powerful) subs into my HT... The frequency is from 29/150 and have a 320w amp per sub... They are connected to my denon 4311ci (xt32-subEQ etc)... After calibration my AVR set the xover to of all my speakers to 40hz (except my centre which is at 110)... My question, is as my speakers are technically only rated to 75hz (not 40) and my subs are reference subs, would I be better raising the xover from 40 to 80 or even 110/120 and sending those frequencys to my wonderful new subs which are currently lacking content. They can handle bass better, have enough filters, and we're bought to help produce a nicer sound all round... By raising the xover from 40hz to 80/110/120 etc all round (or to match my centre) and send all that content to my wonderful new subs which can definetly handle bass better than my speakers, is there any negative reason that I should NOT do this? ... Will removing to much bass from the other speakers cause a issue.... My subs are up front directly next to the left and right speakers respectively... Any advice is welcome.... Thanks in advance. .... Ps... I noticed that audyssey is setting my subs overall db after calibration down to apx 54db should I be worries about this? At the initial set up it was spot on 75db as per subEQ results. After calibration it altered the volume to -8 and -7.5 on the subs but during measurements I noticed that gives a reduction down to apx 54db on my sol meter where as all other speakers read dead on 75db. Is this normal behaviour?
