My in door speakers have just died on me and as I know nothing about this kind of stuff I thought I would ask you guys for some advice. I have Renult Laguna (1997) with 16.5cm in door speakers. I need some speakers to replace these but I don't know the first thing about them. I went into Halfords for a look at what they had and I liked the sound of these infinity speakers: http://www.cel-direct.com/detail.asp?ProductID=36002i265 Anyway, different web sites say they are different sizes some say they are 16.5cm and some say 17cm (least of my worries for now). Also they are coaxial (not sure what that has to do with it) So what I am basically looking for is a recommendation of a good sounding spair or 16 or 16.5 cm speakers that are up to about £50 in price. I have a pioneer CD head unit (bought this last year about April) that plays MP3s if that helps. Any suggestions would be appreciated. Cheers.
