I am looking for some budget (bookshelf - front L/R)speakers in the £50-£100 range(no sub) . They will primarily be used for music, but will also be used for DVDs on occasion . The only other requirement is that they must be magnetically shielded . Any recommendations? Note: I'll probably end up buying from Richer Sounds, so if you are looking for the range of bookshelf speakers I am referring to, then they will be on their website .
