Yep, back when I was getting into HT, talk started up about a new ID company making subs. Started out with 3 models, all cylinders (16-46/low, 25-31/loud, 20-39/best of both) and they set the bar for cost/output value. Been a fan ever since! I bought one of the 1st PB-13 Ultras during their pre-release debut, it's still sitting in my room & it's still impressing me! They deserve their forum, they earned it. And yes, there are other ID sub companies that produce great subs...some which sport a better cost/output factor! Just check out the PSA site, also one of our sponsors (same guy that started it all).
