Thanks for all responses. We have several desktop systems in the house and will not be considering monitor speakers for this setup which is in the living room. It's either a soundbar or no speakers at all since the usage is mainly internet browsing. Moreover, the main hifi system is at the far of the room and it will be playing some tunes when the computer is in use.
Marakanetz, yes, not necessarily Harbeth and it can be any other audiophile companies. Harbeth pops up in my mind since the sound is usually warm, natural and lush and has that human touch to it, which is the opposite of tinny, hard and unnatural of most multimedia speakers.
Chashas1, the diminutive 3's are ideal and many people are using it in their computer systems. Nonetheless, for a very basic and simplistic setup where only soundbars will apply, or setups where no speakers are required, I suppose there can still be a market for good soundbars although most in the market now are usually made-in-China trash. Due to their shape and size, bass and sound quality are compromised. However, good soundbars may be possible if designers focus more on getting the mids and highs right.
Anyway I do realize it is a far-fetched aspiration, on the consumer's part, that Harbeth(or any other reputable audiophile companies) will consider dabbling in this portion of the market since it is mainly monopolied by multinationals or conglomerates. I think we'll see B&W, Vandersteen or Magnepan to come up with such a device first than Harbeth, if there is one available.
