Hi, I'm awaiting delivery of a pair of ProAc D28's and to raise funds, I'm arranging to sell my B&W 803S's. I have a set of Soundcare Superspikes for the B&W's which are really nice (and gentle to my floor). The question is if I should try and sell them with the speakers or if I should keep them for use with rthe D28's. They are of M6 (6 mm outer diameter) dimension, does anyone know which dimension the D28 use ? Or any similar ProAc in the Response range? I'm grateful for a quick response, I already have people who are interested in buying the B&W's. Thank's !
