Would just like to comment on the quality of these speakers. I have owned them for the last 3 years (moving from car to car) and I have to give them 5 stars for their brilliant performance. Being 3 way they provide a v.high quality sound. I would really recommend these to anyone as they have served my gallantly. Thanks
