If they are no good for stereo, they are no good for HT either. HT is not the leftover from stereo, it also requires genuinely good speakers and there are many. These seem to be going lower, but then there are subwoofers for that that do even a better job.
You don't want the sound of the car door closing or the birds singing to be "artificial"?
Joking aside, there are many aspects of HT like drums, voices, music, that require competent speakers. I never heard these, so no specific comments except the general ones above.
