Speaker design customer feedback

Hello, i'm Lawrence, and i'm looking for a source of unbiased, trustworthy information and, most importantly, opinions for my A level speaker design. Hence why i came to this audio forum, and i would like to ask for any personal opinions, and soon in the future, answers to a survey, all in order to really sharpen my design, and consequently, my final product. 
So my question is, what are your biggest issues with speakers, and in what areas would you really want something to be changed?
Your answer doesn't have to technical, it can be do with portability, overall use, connectivity, or even simple aesthetics.
Any feedback would be greatly appreciated, just a small bit of knowledge is all i really need, anything worth sharing would really help. 
Thanks,
Lawrence.
