Front speaker placement, trying wider placement.

Many like to place mains on each side of flat tv. Too me this seems to limit spread of sound throughout the room. And limits so called sweet spot to a one chair position. If u are are hermit this may work but many coexist with others and spreading the wealth seems more comfortable.

problem is mains are so damn heavy that its tough to move them around. At least b&w speakers have ‘wheels’. Also speaker cables can be too damn short. I got 12 footers.

Part of it is the compromises you are willing to make. Most of us want the best possible sound as system owner. So widening the sweet spot will reduce the sweetness of the spot. Having a reflectiveness of a flat screen will confuse the imaging. While the equilateral triangle is a rule of thumb, my experience is that optimal sound is achieved about there. Unless, you are running some odd kind of speakers like Ohm Walsh.

Sweet spot size?  Interesting.

anyone ever measure it?  Would you share with a significant other if only 2 feet wide?

all about dispersion.  Need to get some twine and build a twine enclose sweet area.  Will there be a shareable space?  
Many seem to buy only one chair for listening area.  Are spouses welcome to a listening session?  

Keep out of the corner, or the speaker in the corner will seem louder compared to other if not in a corner. 
 I placed large pillows behind the corner speaker, helped a lot! Took the boom and “louder effect” out.  
   12 feet apart, toed in a bit, 15 feet to my listening position on couch.  Works great for me. Large vaulted ceiling room. 
 Sure my Vega D-9’s sound and fill the room a lot more, but my small-med size towers sound so much better.
