why don't you out of the good grace of your heart school the kid by convincing him to use one of your enclosures designed and built how one should be... It seems that every oneis a know it all sometimes and some are of course worse then others... But if you take the time to let him know that "he who exalts himself and his subwoofers.... Will surely be humbled next to someone who really knows something about somthing, or atleast has some common sense"...
Either help him, by teaching him by example rather then telling him theory...
Or just don't even bother exhausting your energy or breath in discussing any further car audio topics...
However go ahead and print this out and give it to him... It will give him a good indication to shut up, listen, read, and learn. He could have the potential to be the next SPL champion of the world.... We all started somewhere...
My first ever box was constructed out of PB... PB does work, just isn't as good of a material to use for several reasons. Sealed two chambers for a chevy silvorado single cab housing two 12" RF P2's or what ever they were... For what it was it sounded good... Actually to me at the time I thought it was loud as hell.... Then I read... I knew how to build shit, but I read, and read, even bought some lamo DVD's and learned the design principles, and fundamentals... I started off buying audiobahn.... I didn't know.... (BTW I will still admit I own and love the old school Immortal series sub AWISD12)
I have gone through so many systems, (currently don't have one in my new truck... but will be giving that a remedy soon enough)
