Behringer replacement s/woofers for B2092A

Can anyone help me find 2 replacement s/woofers for B2092A. The unit always rattled and when I took it back to the dealer, he said there was no warranty on the drivers themselves as. I later found out that he had blown them him self and then sold them as 'ex demo' - the store is now shut down (it always come around)and time has passed, I cant find replacements, Behringer sent me to Full Compass and they said that they unavailable and don't think they will be getting any. I have looked on line without luck. Any ideas on replacement or suitable substitutes? Thanks in advance, Robert Lyne FFX
