So I've got two energy cf-70 towers, energy cc-10 center so far (working on building a system) I plan on using energy cb-10's for the rears. But right now im looking for a sub. Do you guys think i should stay with energy, or does anyone have a better suggestion? It's a pretty small room, maybe 15' x 25' . Was thinking maybe a 10" ... Dont wanna spend a ton of money maybe around 200 - 400 high end. Any suggestion are appreciated, please advise. Thanks!
