If you are open to use a pair of 2234H and sell your 2235h instead there's a genuine pair reconed by Lydrommet AS for sale in Norway. Price is NOK 6000 which is quite cheap when you consider the exchange rate between NOK and DKK.
2234H is identical to 2235H but without the mass ring, so if your driver doesn't have a mass ring then it's a 2234H.
*I don't have anything to do with the person selling them, but he is a serious guy and he has helped me out with some JBL stuff in the past.
