Tom, thanks for linking Dr. Toole's excellent presentation. It was fascinating as he pointed out flaws in many highly regarded(and very high-priced)speakers, including the KEF 105.2 which he specifically named.
You should also consider studying his book "Sound Reproduction", which I've quoted several times here over the past few years.
I suppose just to muddy the waters a little bit more on this issue, as part of its design philosophy, "Totem Acoustic" points out that they tune their speakers by ear and don't use an anechoic chamber at all.
