I ordered two Peavey Pro Sub Messenger Subs and two Millenium BS 2001 - S speaker poles from Thomann which arrived today.

The subs work fine with my 15" tops but the speaker poles won't fit into the subs properly as per the photos.

The housing on the sub is made of some kind of metal and pushing down just rubs the paint off the poles.

I've emailed Thomann but I assume I'll have to return them. Anyone else come across this problem?
