Fister Roboto

I've called them twice asking for a pair of level 6 12s both times was told that the basket doesnt allow enough of the rear wave to move out of the basket because the motor is too big.

it's about 70". It's plenty for one sub. Hell i have 4 18's with 118" of port and it sounds so good i haven't had or wanted to build a new one in 11 years now. I hope it sounds good though, i will know tomorrow or the next day. DAYUM? Ive always been curious why you ran such a small (relatively) port compared to so many other multi 18 systems. isn't that like 6 sq inches per cube for your enclosure? What was your though process behind that port size. It obviously works very well.

How much port area is on that? port seems slim
