I've both heard of and simply heard more than a couple of setups with Cadence gear. There's a local outfit called 'Scott's Audio & Trim' that sells it. The stuff I heard sounded nice but I'm a bit put off by that bright orange theme that seems to carry through on every single product.
The oddball metallic cones on the dustcaps for the older subs was strange looking to me too. Silly reason to not buy a certain brand, I know, but I didn't like 'em nonetheless.
