RMweb Gold Mr.S.corn78 Posted January 13, 2012 RMweb Gold Share Posted January 13, 2012 Hi Charlie, you can only fit a 40mm x 20mm speaker in a 20 and evn then you may be psuhing it getting the surround on the back of it. From memory you can chop the chassis block apart as the bogie mounts are at the top of the block in the form of plastic plates. You can also fit a 40x20 bass enhanced with a bit of filing/carving of the edges. Stand to be corrected if i am wrong cheers Simon Link to post Share on other sites More sharing options...
