Hi, Looking for centre, rear and sub woofer to add to my existing Tannoy R2s. Room is quite small - 15ftx15ft, and rear speakers must be reasonably small to mount on wall. Prefer sub to have no more than 30x30x30cm and centre does not need to be shielded as it will sit under a projection screen. Speakers powered by TEAC AG H 550 AV receiver, 55w per channel when driving the 5 speakers. Pre out for sub woofer. Grateful for any suggestions - and what speaker cable to use - QED Silver Anni on R2s. Is flat cable any good for the rears?? - as I can then paint over it. TVMIA.
