Well reviewed active bookshelf speakers from Edifier at good prices. Can be used as both computer and media speakers. The R2000DB and S1000DB in particular have optical input and are a viable alternative to a soundbar if a surround sound system is not an option. For me the R2000DB is probably the sweet spot for price/performance.

I bought the r1280t from Kogan pretty good sound, wish the power was on the remote instead of having it at the back which is annoying if you actually have them in a bookshelf.
