Hi, I'm interested in building a powered sub for less than $150, if possible. Right now I am using Axiom surrounds, along with a Cerwin Vega 10" powered sub that was a left over from my previous Cerwin Vega "home-theater-in-a-box" setup. This is the only sub I have owned, and it sounds pretty decent to my ears. For Christmas, I am setting up a surround sound system for my parents. They are getting the surrounds from the Cerwin Vega set, and I picked up a Pioneer reciever for them. They need a sub though. So...my question is, what can I build for less than $150? Can I build something better than my current CV sub? If so...I will keep the DIY, and give my parents the CV. This will be my first DIY sub, so I would appreciate some tips on what I need to buy, and where the best place is. I have used PartsExpress several times, and have been happy with them, if I can get most of my parts there, that would be a plus. Also...I can do the boxbuilding myself, but I would like to know what type of wood will be good to use, keep in mind I would like to keep the price as low as possible. Thanks so much for any advice you can give!
