I just received my pair of these in the mail but there are markings on the caps. How does one tell the card from the subcard. I will obviously know the omnis as they are coming in the mail via a separate transaction.
You can tell the difference from just looking at the top of the cap: the cards have lines across the top face, the subs have no lines. The hyper caps are bigger than the cards, but also with lines across the top. I don't have omni caps.
On a cool note: I bought the CEMC6 set from SoundPure two years ago and the shockmounts have taken a shitload of abuse and need to be replaced. Called SoundPure to buy replacements, they contacted John Peluso and he's sending free replacements. Sweet!
