Cross over frequency ???

Sean..."Versatility"? My Rotel 1066 is so damn versatile that half the time I can't figure out what it is up to. And the manual isn't much help. I do hear a lot of complaints about "bass handling", so perhaps the solution is what I have done...set all the speakers to "large" and get some separate crossovers for the speakers which aren't. I am in the process of wiring up three Marchand crossover modules and power supply in a decent chassis. The modules and the power supply are completely assembled so the wiring job is pretty easy, and the whole rig, including $40 chassis and gold plated connectors will end up costing me about $150 (three channels). For another $60 it could have been 5-channel. My old Audio Control Richter scale (2 channel) will do the rears. Of course, if you have more money than time there are plenty of crossovers available for sale complete.

Lions and tigers and bears oh my.Since the problem is in the sub woofer and associated electronics and the monitors seem to be doing fine on their own this is where I will begin.I will use the parameteric to tame room modes and an eq ( third octave ) to roll it off.Who the heck knows.I wish my processor had more bass management.........

To whom it may concern.Problem solved.The problem with switching xover freq. on the fly is that the room modes increase in amplitude as xover freq. increase in frequincy.Example...I switch from 65hz to 80hz and I now have to take into account the new freq. the sub is producing.One of them is an octave above the killer 42hz mode, smack dab in the middle of the xover point.Once I ran some sweeps with the trusty testocilator (thats not a joke,its a tone generator)and the rat shack meter I quelled some junk at 80hz and above.Alls well again and the system has gained some headroom with the new higher xover point.Nemo sounded outragous.
