Yes fine they'll be for TV sound. You might be well advised to have a look around for some second-hand hi-fi grade speakers. A couple of Tannoy's would be fine. I picked up a pair of QUAD 11's for 150 a while ago and there're excellent for that sort of application..
Or if you've got time spare you can make up some half decent DIY ones they used to have kits of them around you can make some very good units that way which will blow away the computer active speakers and or sound bars.
I think you'll be quite surprised how much better good sound reproduction can make most TV viewing a better experience....
