The bass perfomance of the Kiis was the main area where they fell short. They certainly didn't sound "ported" in that the low frequencies started and stopped accurately, but they seemed to lack pitch definition and bass extension.
Interesting. When I had the Kiis at home their bass pitch definition was one of the attributes that impressed me most - for example, I was able to follow bass guitar lines and the precise notes being played (i.e. their pitch) much more easily than before, which is why I made the comparison with the first time I heard an LP12. They Kiis did sound quite a bit "lighter" than many other speakers I've heard but I put that down to those bringing along the extraneous mush from room reflections etc. Balance wise, my Obelisks have far more bottom end but it's less easy to follow (noting that the Kiis cost way more). Ultimately, if I can hear what is being played with greater clarity, then to my mind they are better.
As ever, all of this points towards a dem, preferably at home. I care not one jot for measurements. I use my ears since I listen with those rather than microphones.
