Dave, I bought a WMD2 15 and I attempted to put my first DMX softparts in it and I failed, miserably... I believe the VC was a bit too thick. I'm therefore needing a new set of softparts for it but I'm wanting something with a FS of around 18-20hz. I'd also like a wide rubber (butyl or epdm, it doesn't matter) surround and triple soft spiders or dual mediums with a spacer if at all possible. I'll leave cone and DC choice up to you, I just want a conventional dustcap, beyond that I don't care if it's CF, poly, coated fabric, paper or metal.
