@redstar....*G* Agreed...and I'm playing into a larger volume of space..16dx 21w x 12h(average)...and decidedly 'industrial'....
..and mine are more the DIY version of the HHR TLS-4's...slightly larger, not so 'pretty', But...I'm working on the latter....;)
(...and right now, 'the walls have ears'...so I don't want anyone to think I'm trying to sell shares in the Brooklyn Bridge or 'lake bottom property' ...but...)
Omni's in surround sound are definitely Different than typical driver systems. Even without 'surround enhancement' by the equipment, without 'adult beverages' or whatever your state (regional, not mental) allows....
Above average studio work on some recordings seems to have this marked tendency to 'place' instruments and occasionally performers into perceived locations that may not be noticed with 'normal' speakers.
Now, this may be induced by phase interaction/interference patterns of the waveforms they generate . And,not to ignore the reflections off of walls, furnishings, and anything that exists within a given space.
I have plenty of those, as do most habitable spaces. *S* In my near future, I intend to 'set up' in a new one that promises to have less of that, and be decidedly 'clear(er)' of these 'early reflection elements'. *L* So I hope to either dispel or enhance what my senses try to make sense of.
Anyway...I thought I might broach my experience with you, if only to hint at what an omni system might be if you really become not just a convert, but a fanatic. There's not enough of 'us' around...
"Embrace the Force, Luke!" *L* It surrounds you, after all....;)
(As for those 'others' reading this....you can start throwing your 'bricks' now....;)..."Shields Up" *L*)
