Help.

G'day to all out there from Australia. I'm new to this Forum and would like some help and advise.
My hobby is woodworking and I have always wanted to build a portable Bluetooth Speaker using quality products for good sound. The cabinet is no problem however, the components to use is, ect: what speakers to use and how many, and all the other stuff I will need? If anyone out there can help and advise it would be very much appreciated.
Cheers
