Graphs Room Placement / BSC effects

[cobbpa]

Does anyone have handy a graph of a speaker placed correctly in a room (according to the BSC designed into the crossover) and then a graph of the same speaker pushed very near the rear wall? I was just thinking that I've never seen two graphs depicting the way the placement changes response. I realize that it depends on the drivers, BSC in the xover network, etc., and that a rear-firing port may be thrown way outta whack by the change. Just curious, more than anything.

Never seen any.

BSC has nothing to do with the port. The frequencies involved are much higher than the port tuning. Here's something that may be of assistance....

To estimate how the room with affect response you can use the software at http://www.pvconsultants.com/audio/frdgroup.htm. For room acoustics info and setup procedures for your loudspeakers you can go here : http://www.wilsonaudio.com/technotes/index.html and click on room acoustics. But most importantly trust your ears.
