I realize you have looked at a frequency response graph of the speakers in question and you don't like what you see. Most speakers don't measure anything like electronics and speaker design, especially with a low price target is difficult. Besides, what special knowledge do you have which qualifies you to look at a frequency response graph and say it's a fact and not an opinion that the design is defective with no claim you have ever listened to them? That is coming down pretty hard. I don't own these speakers and I don't take your remarks personally, but this kind of behavior has already caused me to reduce my involvement in internet forums considerably.
I wasn't trying to say these speakers were defective. I said I suspect that they are deliberately coloured, since the frequency and power response is tilted up by around 6dB at each end of the frequency spectrum in the on-axis response, and this is not compensated for in the off-axis response. This effect is precisely what a "loudness" button does on an old receiver, and is an effect that many people find very pleasing, especially at lower volume levels. This would be viewed as a defect only if the goal is neutrality, but like I said, I don't think that was the goal in this case.
I hope it was also clear that all my statements were merely opinions and not facts. My apologies if it wasn't. However, FWIW my opinions about speakers come from designing them, partly for a living, and from being reasonably up to date with the research on this topic.
I also don't think it's problematic to be critical of a speaker's measurements or design on a public forum. In fact, discussion of a speaker's design or measurements helps us all better understand what a speaker is doing and how, just in the same way we all discuss the design and performance of electronic components on this forum.
I'll try to be more conscious of my tone in future
