Similarly not too sure why they didn't publish your post. Usually they will only censor posts that are not in line with their interest. One possibility I can think of is the variation in the frequency range between the super-tweeter and tweeter. A super-tweeter is supposed to respond higher in the frequency spectrum, usually above 25kHz which is the upper frequency limit of human hearing. However, the specs of the SHL5 shows a frequency response of 40Hz-24kHz. That implies both tweeter and super-tweeter do not extend above 24kHz in the frequency spectrum.
A thread on tweeters may raise questions on the use of the super-tweeter in the SHL5. There was a discussion on this topic on HUG once and if I'm not mistaken, Harbeth had clarified that the super-tweeter is in the SHL5 to satisfy market demands. If someone were to interpret it in another way, well you know what that means. They may be trying to avoid this sort of discussion, hence the censorship.
