DIY subwoofer suggestions

Hey everyone, I have gotten pretty handy with the carpentry as a resut of building my studio.. And I need a subwoofer, or maybe two to go with my JBL 4410A soffit mounted speakers. I was considering checking out some reasonably priced subwoofer drivers to use for a diy subwoofer. Anyone have any suggestions for a good driver? I am ok with used. Not sure if I would want to build the speaker box as an air tight box or a ported design. I suppose different drivers are made for different designs? ..I'm just starting out this research process. Any thoughts? Oh, and I have a rack mounted crossover already. Thanks!

Eric Best and Barefoot would be the guys here on the forum who would be able to help you most with that. I hope they are around! Speaker design is a complicated science and art (and a bit of voodoo too, I think!) that takes a lot of dedication to learn. They are the guys to give you advice on how to go about it. - Stuart -

Thanks Stuart, hopefully I will hear something soon!

Hey Tone, unfortunately I'm not much on subwoofers. You might be able to get more info here http://techtalk.parts-express.com/

Nice! Thanks so much

Here are some of my favorite resources: http://www.avsforum.com/f/155/diy-speakers-and-subs http://www.hometheatershack.com/forums/diy-subwoofers/ and the best of all if you have adjacent attic or unused space... http://ibsubwoofers.com/ and http://ibsubwoofers.proboards.com/ Someone at one of the forums will be able to recommend you a particular driver and design for your application. Or I can help you here if you like! There are many good drivers in the $200-300 range. Good luck!
