Well hey guys, After a rousing look around the internet, I am still confused..... Right now, I want to get a GOOD subwoofer, and I know for a fact, I can't go retails direction. That being said, I need a sub that plays TIGHT BASS, but has PUNCH that'll shake the house. the room dimensions are: 20 by 20 by 10. What drivers would you guys reccomend? What amp? Could I hit reference with this baby? I am thinking about tuning to about 16hz. Thanks guys.
