Hey guys, first post here. Ive already become bored with my STF-2 & would like take a pretty big next step. I would love a PB12-2+ but dont want to dish out $1100 for one, so Im looking torwards the DIY route. This will be my first time trying to build a sub but Im not worried by that because I think I have the qualities that would be helpful like patience, im picky about details & I think its more fun to build/work on something yourself since you gain alot more knowledge & satisfaction. Also my brother has a bandsaw & router so that helps I have been reading up the last 2 weeks on others DIY projects & have heard good things about the Avalanche subs, 15" or 18". Im wanting to build a sub for only hometheater since thats all I use it for so its going to have to dig deep & I want to really feel it. Also if anyone could give a sugguestion on a good book to read on how do build speakers that would be great. So if anyone has any sugguestions for setups I would really love to hear them.
