Hello people of the Home Theater Forum. Im new here and this will be my first post. Let me introduce myself. My name is Scott. I am 16 years old and I have been into HT for about 5 years now. (about in 5th/6th grade for me) I consider myself pretty elite in this subject. I know more about HT than anyone I know. Reps from Lexicon, Vidikron, Sunfire, DTS all asked me the same thing a year ago when I was at the Home Theater Expo in Newport. "How do you know so much" and "Will you work for us" (sorry for this bragging, I just want to let you know you dont have to talk to me like I just bought my first DVD player at Best Buy and think Im the "HT KING OF THE TOWN") Ok ok. Im here to learn from you cool people about HT DIY. I just came here 2 days ago and read about sonosubs and the like. COOL!!! I have allways wanted to build my own speakers but could never afford it, know how, whatever. Hmmm... I dont think I even got to the question yet. Well, I want to know where exactly where should I start in the DIY arena. I dont really know the REAL DEEP technical stuff about speakers. The only thing I see that I know is Xmax and resonate frequency. I have no idea what Q and the like mean. I see them said a lot around here. I know what Im interested in a DIY sonosub that I would like now. Heres a list of priorities for it. 1) Tight, tuneful, musical 2) Extension 3) Output 4) PRICE $$$ CHEAP CHEAP $$$ 5) Size I want something in taht order that runs under $700. Ive been tinkering with my theater and it looks like Im not going to get any more extension in my room. I have a Def Tech PF15TL that I had to save up for about a year for and just in the last month Ive got it pretty good. I think it could do better but my room sucks aise. I can get it to sound great under most material. But I am furious under its bottoming out on some material. (good thin it never really happens.) Namely its from the Haunting(dts) when Lily Taylor is pulled off the bed. Titan A.E.(dts) Most Titan shots in the silo lifting up and up and when a BIG chunk of the Earth hits the moon. I love that stuff but if I want those scenes at "BLOW ME AWAY" levels, it will bottom out. Just so I dont have to waste time, my sub is fed straight LFE. Nothing else. All my speakers are full-range(to an extent). Ok. I dont know what IM forgeting to tell you guys so I will end it here. Please help me become one of you guys. Im a newbie. The new recruit. The "kid".
