Put my DB12 together the other day and I have some questions about how the woofers are supposed to be installed. Currently have it with one woofer mounted on the face of the insert with the magnet assembly facing into the insert. Happy with the sound but I have a second matching woofer I'd like to install and can't find anywhere in the plans that tell you how to do this. Any help would be appreciated, trying to get the most out of this great box!

Oh, I'm using Boston Pro Series 12" subs (12.5LF).

Thanks, that confirms my suspicions. I'll give it a try and see how I like it. Out of phase I suspect, on either side of the baffle should do? Hmmmm, can't wait to see how it sounds and how my amp likes it. Really impressed with the design of the box, super sturdy!
