I also have my Ohm Walsh Tall 2000’s set up in a very similar configuration. 1 foot from wall, 6 feet apart with my audio/video cabinet between them and 10 feet from main listening seat. Set up diagonally off a corner with a single sub in corner. My room is open design 24’x16’ with 9’ average vaulted ceiling and hardwood floors with rugs. Being semi omni speakers the only treatments needed was a corner bass trap in the corner behind them. Agree you can move around the room with minimal SQ drop. I agree the sound is just so realistic and sounds more like live music than other speakers I have owned. Just love these speakers in my living space.
Fyi- are you aware that the new Ohm versions have a 3 position attenuator switch on the crossover board. Off/Med(factory setting)/High located behind the speaker terminals. When I received my speakers they seemed a bit veiled and dull. When I switched the attenuator off my room came alive. This may not apply to everyone but a nice hidden feature that allows you to adjust to your liking.
