Using Four Eminence Lab 12's Feedback!!
 

Hello everyone I have six Eminence Lab 12 to my disposal. I am only going to use four and the Other two can be spares. Now you are probably wondering why I am using a Pro Audio Driver. Well from experience I know these get low and pretty loud. I am not looking to win trophies right now just a little boom boom. I am going to be doing a build in my Mazda b2600i Which is my daily POS till next spring. I was just wondering what you guys thought about these sub good and bad feedback is welcome. I also will be using Russian Birch 3/4 Ply for construction.


Here is a link to the woofer. I get these subs for free in the box and recone kits as well. LAB12
