I would hazard to say the Emerald Physics model is to stall so that you cant remember how they sounded and the customer cannot send them back because you've had them for too long. It doenst matter what wild and incredible promise that they made to you that if they don't sound as good as what we had them like.. its all a marketing ploy. And I think you'd find that even if you convinced them to issue an RMA number to ship them back to them at your cost, you'd find that the issuing of the cheque back to you will never happen or will be stalled for just as long in hopes you'd simply give up and forget about it.

If you look at the Axiom model, they ship a fully working and can easily get sounding excellent speaker. You have problems, they will be more than happy to get on the phone with you if there is something you are doing wrong, or if it's a technical problem then ship you out the replacement parts right away. Then give you the 30 days to actually evaluate the speakers in your own home on your equipment. That is not the standard business model for the speaker of HiFi audio community.
