Speaker Suggestions?

[FatalPotatoe]

I have been with my Mordaunt-Short Avant 906 speakers for 2 years now, but they are starting to disintegrate, as the cones have bumps and holes in them (you might not be able to see it in the photo) and one of them went through a make-shift tweeter replacement that came from a krk rokit 5. I am probably going to sell them as used. Any new suggestions for a pair of floor standers or bookshelf speakers? (I built myself a pair of speaker stands just in case I come to a bookshelf speaker). My room is quite small with a very tall ceiling of 10ft and I compose electronic house music in FL Studio. I am also getting a 40W 2.1 amp very soon and have also built a sub woofer that I want to use.
