Kristian may be a trained listener, but I'm a trained measurer. In my listening room, the Ohm 100s are unusually flat (on-axis at the listening position) with a smooth, gently falling FR from north of 10khz down to below 150hz - where destructive room effects take over. I address those room effects with hemholtz devices and EQ'd subwoofers. Bottom line: this is an usually neutral design (same caveat: measured on axis in my space) from the upper end of the bass on up and, subjectively from the upper bass through the upper limits of my hearing (about 14khz, last I checked).
The distinguishing characteristic, of course, is the omni-directional dispersion pattern. Conceptually, this should smooth off-axis response, but, in truth, I've never confirmed that. I can say with some confidence that the spacial impact (can't tell you how to measure that!) dominates the subjective impression that this design makes. The final decision will likely be subjective and have little to do with "sub optimally flat FR", unless the listener in question objects to this particular (gentle) deviation from dead neutral.
The "gushing" for Ohms upon first listening is almost certainly due to the "omni effect". MBLs (a subjectively less neutral design to my ear) get the same kind of reaction - WOW! Some love it at first, then tire of it and move on. Others stay the course. I'm just about a year and a half into my time with the Ohms and generally prefer them to several other highly regarded (and IMO fine sounding in their own right) speakers that I also own, each of which cost many times as much as the 100s.
This is the preference of my "somewhat trained" (app. three hours/day at the piano and/or guitar over the last 2 years) ear. I accord my opinion no more weight than any other (Kristian's included), but I do hold the measurements in high regard.
