Here's a nice one for you all!!!!!
I have four Celestion Ditton 44 speakers tht I have restored, ie checked for airtightness (which they were not but now are) and replaced caps, new wire, all very nice blah blah blah. Because of the position of doors in my room, I have the rears to my sides 9 feet apart, facing each other square on and but one metre forward of my head postion on the couch. The fronts are not set as wide apart, some 6 feet part and 9 form my head. This gives pretty good seperation all round, and there are no "holes". That said, something interesting happens. Very low bass on organ cancels out, but I invert my decoder (SQD 2010) which reverses the phase to the fronts, the bass is there and how, and the rears suddenly come on a load louder too. I assume this must be cancellation caused by time differences and angles?
Or........
Amplifier inverted phase at either imput or output?
Any takers?
Thanks,
Richard
