I did compare them, if Rel would be better I would have said it. It is as it is. This is about quality. About timing, nothin more nothing less. I do not say Rel makes worse subwoofers. The only thing I say; they are not the fastest. Paperunits are not fast in respons. That is why other materials are used these days. Lighter materials means faster. Faster means better integration with the speakers. I think it is time for Rel not to use paperunits anymore. I am always looking for the best quality in every pricetag for my clients. I want them to get a 10 ( A) and not an 8 or 9 ( B) This is about good
, better best!
