This could actually be true in some circumstances, but generally, it is because we are presented with more channels of information with HT/surround, whereas music is usually 2 ch. Our discrimination of loudspeaker problems diminish with increasing channels and rises with decreasing, to where we are actually most sensitive to some issues in single channel mono. IOW, some deficiencies are hidden by MCH, brought to the forefront with 2ch.
With regards to the Tekton and other similar HE designs with wide range drivers + (super) tweeter, this is often guided by the fact that many will be driven with low power..and more importantly, low feedback design amplifiers, like SET tubes, etc.
these type of amplifiers are highly susceptible to the reactance of typical multi-way/XO speakers, which have quite varying impedance vs frequency curves.
The wide range drivers + (super) tweeter (say above 10k) will have a very benign, gently constant curving type impedance, except maybe in the upper treble range, outside the "critical band" of 300-3khz, lending themselves to less EQ effect and nastiness when presented with a more typical multi-way design.
