Ive currently got Tannoy SFX 5.1 satellites and sub, with a monitor audio R180HD center channel hooked upto an AVR1909. Id like to get a pair of R90HD's for the front to match, but knocking 300 notes for 2 speakers won't go down well with the missus. Ive heard the R45's wont be much better than the Tannoys as they don't have separate tweeters, but I can get a pair for £99. Ive seen the Vector 10's, and they're in my price range, but my question is, will they suit my R180HD better than the Tannoys and is it a worthy upgrade?
