Im not sure in £'s, but i recently bought the Logitech z623 2.1 Speakers for a bit over $120AUD. They have been performing really well in my opinion with a good balanced sound and when you want extra bass the subwoofer doesn't disappoint. These speakers are THX certified, which really means nothing but its gives you the peace of mind knowing that somebody from THX may have had a hand in the production process.
