Hey guys! Im trying to piece together something decently cheap but still good and im pretty sure i want a sub in the mix. I listen to music and play xbox 360 alot so i think its crucial. Bad thing is that im a college student and money is tight. I was wondering if you guys could help me out as im new to the HT-Sub world. I dont need something just rediculously loud but im NOT looking for a sub like you can get in a HTIB...somewhere in the middle...the lower middle actually haha. I'd like to spend around $100 if possible. I dont know if it is possible but im checking Craigslist.org and local boards but im just not sure what good and whats not. Im hoping there a decent sub for under or close around $100. Thanks for the help guys! Oh room size is about 12x20 and pretty open. Thanks!!
