I’m in need of a new sub as my current sub Yamaha YST-SW205 no longer produces any sound. It turns on but no sound comes out of it. I have tried different sub input on the amp and tried different RCA cables, I guess over a decades use its dead. I am going to use this opportunity to perhaps upgrade my 5.1 setup. My current set up consists of; Yamaha RXV 667 AV amp (bought a few years ago and not looking to upgrade) Wharfedale Modus Seven Floorstanders Wharfedale Valdus Centre Wharfedale Modus Cube Rears (it’s the 2 cube tower design) on a swivel bracket My room size is approximately 12ft x 12ft. The Wharfedale speakers are over 18 years old, they were my very first home cinema speakers back when I was living with my parents. They still work fine but would like to upgrade as I’m sure new speakers will improve the sound quality. I will be using it for movies 90% of the time and perhaps 10% music. My budget for speakers and sub is approximately £600 - £800 all in black. I need advice on what speakers and sub to get. I know from reading previous threads that the front 3 need to be from the same model and series but does this also apply to the rears/surrounds? Should I consider the bipolar speakers for surrounds? Are they better than bookshelf speakers? I’ve found a Wharfedale SW150 sub for £139 from Superfi – Is this a good buy? I’m considering the Wharfedale diamond 230 floorstanders but I’m worried about something I read somewhere here about the grill interfering with the tweeters sound. Does this model suffer from this? Other models I’m considering; Monitor Audio Bronze BX5 AV 5.1 (cannot get any longer as it’s discontinued, all I can find is ex demo) Monitor Audio MR4 AV Black Oak 5.1 @£699 (these are all 6ohms not sure if that is a minus) Monitor Audio Bronze 5 (a little over my budget but maybe I can just get the fronts and centre and buy the sub from different manufacturer) Wharfedale Diamond 155 Walnut Pearl 5.1 Speaker Package (these are well within budget except not in black and concerned about the poor finish and quality control) Wharfedale Diamond 200 Series Black 5.1 Floorstanding Speaker Package @£1047.95 (slightly over buget not sure If I should get the DFS Bipolar surrounds audio visual sell £120 instead and get the Wharfedale SW150 sub from Superfi to save money) I am totally confused not sure what to get. Please advise ……. Thanks!
