I have two rooms that I will need some speakers for my front left and right and rear left and right speakers in my 7.1 surround sound configuration.
Room 1- my budget is £1000
Room 2- my budget is £150
Any help is much appreciated
For room 2 you might want to check out the Monoprice.com bookshelf speakers. A pair is something like 80 bucks. Not sure about shipping overseas though.
For the expensive ones you probably want to take some content to some places where you can listen and play with different speakers for a while. Speakers in that range are pretty subjective devices so you might like certain ones just by the way they sound over the spec sheets.
The home theater style ones are meant to pair with a system with a subwoofer though, which is why they only are rated down to 110Hz, since the sub should take over below that. If you don't have a sub you probably want something that covers more range.
