Our last gig got me back to considering a possible cure for the typical narrow guitar cab's dispersion. I really don't care for the fact that any resemblance of what ever tone you have set, only exists in a 30 or so degree cone in front of the amp, and half the time you can hardly hear other amps just several feet away. Obviously this is for smaller gigs not a miced up stage setup. I worked up a few examples to see how this might pan out with a 13 deg cab. But a stage plot here led me to rev2, with each speaker 20 degrees out. Basically at this point I'm looking for advice, first if there's holes in the idea I've missed, if not, some help with speaker questions, or cab makers could be helpful. BTW I run a LoneStarSpecial usually, up on a bench already and with the Mitchell Donut'. That really does help with the very top tones spread, but that is neither wide enough nor meant to effect low enough in freq.
