Hi all,

I am looking to build a subwoofer or a pair of subwoofers to complement my 2-channel music system. My system is comprised of an Audio Research LS3 preamp and a Yamaha PC2002M amp. My speakers are JBL L5s. I have another Yamaha PC2002M at my disposal that I could use for a sub or pair of subs. I would add an active crossover to the system for the sub. The room that this system will ultimately end up in is about 12' x 12'. My thought would be to add one 12" or 15" sub in the smallest enclosure that I could manage since I do not have a ton of room. Forgive me but I am new to DIY speaker building in general and a little out of my element. I do have a woodworking friend that can help me build the cabinets.

Does anyone have recommendations for a good driver and/or cabinet design that could achieve my stated purpose? I am going to continue to educate myself by searching through the threads here, but I thought I would get a head start by laying out my project. Thanks in advance.
