I wouldnt have to see any proof that these woofers are legit. I trust the company, used plenty of their woofers in some of my installs, never heard a complaint. And I see the new DD Redline sporting a very similar basket //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif and I have to say I love the way they look. It's a woofer you would want to invert for sure! Or maybe that's just me.
But you see that bottom line and then its like stealing at that price. I expect these to be popular
