Eric was so kind to send me the prototype to do some pre production in field testing. This is nowhere near production level cosmetics as Eric hand built this woofer as purely a test mule. Iíve only had it in my car for about 24 hours, but my initial impression is that it is very, very impressive. It plays extremely low with authority, but has enough motor force to keep cone control on point. It out performs my Kicker CompQ, which is also a low distortion, high output design and a very capable driver itself. I cannot wait to get this paired up with the Stevens Audio SA6CS set in my customers 2016 Colorado with some real power as I only have 250w on it now. I personally think Eric knocked it out of the park with this subwoofer!
