So you screwed into the cab itself??? I'm confused...... ***on the other note... my current box was louder with a single woofer and an open woofer-hole than my test box was... it did 145's without the second woofer being in the baffle... (at a much higher frequency.. like 62-63hz...) I've had my son for a few days so I haven't gotten anything done... if I try to build he wants to help.. He's super clumsy and doesn't mind when you're not looking, he'll just turn something on and try to use it... (wether it be a saw, sander, ect... if dad can do he can... or he thinks...) He starts school next week so he'll be back with his mom and I'll be back to playing. Yup, screwed from inside the box into the back wall. Why was the woofa not there?
