@rooze I'm with you on the dipole. I think that any dipoles will require too much space behind and beside them for me to seriously consider trying them out. Although I do believe that you don't know until you try.
I have been looking at Ohm for quite some time and I do believe that the Walsh 5000 could be an excellent attempt to make it work. I may have to take advantage of the very generous at home trial period that Ohm offers to see if these would work. At full retail pricing, I'd have to start selling off a lot of equipment that I may not be ready to part with just yet.
I have been speaking with John Huff of Huff Loudspeakers about some of his Omni's that he has leftover from his days in the industry. He seems to feel confident that his Huff Three would do well in a corner such as mine and is willing to make a deal. There is much debate about omni's out there and the lovers and haters both make great points. With my limited knowledge, I think that dipoles would be tough for me to pull off and omni's could be even harder to get right. Any thoughts on omni's for a very wide separation and corner placement in a big room?
