I am considering a DIY sub and would like some recommendations. I would be grateful for any suggestions because this is my first DIY sub project. Here is my situation. Budget is $700. More if need be. Size of the sub doesnt matter but not IB. Ported? PR? Sealed? I have a Onkyo 5200(?) amp just sitting around. It is 150 watts x 2 but it cant be bridged. Could this amp be used or do I need more power. I have access to all of the tools that I need. I can get true 1" oak for $2 a board foot (not linear). Could I use oak if the pours are properly sealed. And best of all the wife says "why ask, your going to do it anyway". She is so smart.
