mapman, yes, that's why I stated true omni as problematic. He could make a quasi-omni work, but still it's not ideal. I concur with there not being a clear step up transitioning from small ESL to small omni. He could force the issue, but has a wall all along one side versus open on the other which might slaugter the soundstage. Who knows how much that would screw up a pair of omni speakers. Imo it would be the least favored genre of speaker to use for that location.
You iknow I'm not anti-omni; I have the Walsh Model F running now along with the Legacy XTREME XD Subs. Maybe it's just me, but they sound very good with nostaliga music from the 70's.
