So I know nothing but all this speaker building business has me very interested. I love woodworking and the prospect of building a quality sub for cheap while having a cabinet to match my decor is a very attractive option, over the premade over priced Best Buy stuff I have been hearing. I am going to need a sub adequate for HT/and Music for a 15 X 15 room, nothing to big. I am looking at the Dayton 10-12 inch Titanics, or any other high quality subs that size designed for sealed enclosures that could be recommended. A have read a sealed enclosure is easier for a first project, that I can make with some sort of plan. 1) I know I need an amp, probably 250 watt. Is there any other hardware (wires, etc) that I need? Or does the Amp connect directly to the driver? 2) I know what crossovers are used for but I am not sure if I need one for a single driver sub? Do I? 3) how small could I make this? I have read that shape matters little whereas size/space matters more. True? I would like a smaller sub. 4) I am going to have to get better at sodering I assume. How much sodering is involved in a project like this? 5) If I am using a 6.1 reciever with 8 ohms to 6 channels can I still use a 4 ohm driver for the sub? I assume I can since if I connect the reciever to the sub with an RCA type sub cable and its a powered sub then it wont matter at all. Any information is appreciated, your teaching a baby to walk. I have legs, but when I look at them I am not quite getting how this works. I have seen some of the kits on partsexpress that claim one hour build time, that is perfect, but I would prefer to have all the hardware and make my own cabinet out of fine materials. I am assuming I would need to brace the driver and am not sure how I would do this. I know I could REALLY get into making my own audio equipment but all the tech talk and equations have me rattled.It would be really nice if someone could tell me exactly what I need, and what I need to do to start this project.Thanks for any advice you can provide.
