Omnis are, and will remain, the odd and distinctive animal in the speaker zoo...
They demand care in placement (location, location, location....we're heard that elsewhere, right?).
They will be effected by the space they're in...the size, the materials within it, and the shape and proportions of said space.
To eq or no will be subject to above, the equipment 'upstream' (gee, what a surprise...), what's being played, how it was mixed, and (of course) taste.
The fact that this thread stretches 52 pages is amazing. Particularly to me...*G*
And the fact that the reviewer in the posted review can only put the Ohms up against the German Physiks? At that price spread? Damn....
There's other omnis...are they 'also rans', or has the field narrowed to that degree?
Wow....
Pardon me....I've got work to do....;)
