Its the new Hixsub, 1/2 as loud, 1/3 the price, and sounds like a funky pup //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
Im perplexed by that 18" basket too... My guess is that someone got happy with the unibit on that one. I cant see how it could be tooled to make holes that shape in the basket (from a 2 piece tooling).
As for the other 10 pages of BS... I take the 5th //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
That basket was just custom. Not sure if it was thought of as a cooling method or what. It was Reconed with atomic soft parts and actually had a atomic spider landing clamp tek screwed to the basket.
Dave Reid is who put it all together and I'm not sure he is a member here.
