Speechbubble speakers

Hey guys and gals! I saw this cool speaker design on Yanko, speechbubble speakers. essentially two speakers in the form of speech-bubbles. (see link) So I was wondering how to go about making speakers in this style myself. Would I use two speech-bubble shaped pieces of wood with a cutout for a speaker, connect them with little wooden blocks and cover the sides in some sort of flexible wood and the front with black speaker fabrick and paint all the wood a glossy white or what? Would I be able to fold real plastic around the wooden sides, as it would be with the real speaker design? Or do you gals and guys have any other ideas? Images below!
