I'm looking to upgrade my system to DTS/DD5.1 and have decided to go for the Yamaha A5 amp. What I'd really like to know from you guys is a recommendation of speakers to go with this for around £400 - £500. I currently have a pair of Acoustic Energy Aegis One speakers and would hope to incorporate them into the system. I had thought of using the AEs as fronts, with Tannoy MX1s as rears, a Tannoy cente and the Tannoy sub. Would this work? I also would be interested to know whether a subwoofer would sound too loud in a fairly small room (4m by 3m). Any suggestions would be greatly appreciated.
