i think it’s a cool idea too but there are probably too things i would change to make it both “modern” and consistent.
-
the use of wood makes it seem dated. try rendering it in stainless steel or even transparent plastic, colored or white.
-
get rid of the shelf. it feels like an extra piece just stuck on there. you can use the same principle you are using with that shelf by just extending the top part of your speaker. because it can directly access the internal speaker wiring, that would be a perfect place for an mp3 dock.

i would also thin the thickness of it as well, also adding to it’s “dated” look. play around with putting some curved edges on it to make it a bit more sleek and up-to-date.
