Ok, Im thinking I want to tackle building a sub or a couple subs for my home system. I currently have klipsch rf-82's out front powered by a yamaha rx-v1800 receiver. My room is 13 1/2' by 21' with a ceiling that tapers from 8 to 10'. I want the sub to be able to keep up with the rf-82's. I listen to mainly music so I was thinking a couple of small sealed enclosures. this would also work good for placement. I have 2 open spots on the floor on each side of my tv stand. This would also be my first build so complexity is an issue also. Money is also an issue, I was thinking i like to keep them under $300 a piece or if just one under $500 or so. Thanks alot for any ideas, really appreciate it.
