    looks like this woofer still has plenty of excursion left to break in and use. Once the power level and box volume are fine tuned, we'll be able to play this setup even closer to it's maximum limits! Bass songs - test tones, you name it - This install should be able to play ANYTHING once we're done tuning amp settings, adjusting internal cubes, and finding all the weak spots that vibrate in the car. For now, we ran the speaker wire through the port until we can add official terminal cups. So far these Level 6 15 inch subs are VERY IMPRESSIVE sounding. Good job DC Audio! She's slamming much deeper now too :) But why wouldn't it with over a 100 lbs subwoofer, right??? Just about the biggest size before the lower back starts breaking... Bottom line...Crazy hard hitting lows - Great bandwidth with nice and loud peak spl frequency around 40hz tp 45hz... Not sure on the loudest decibel score yet, but it's way deeper than we thought. Overall a huge success and a really fun way to connect with car audio friends :) THANKS FOR WATCHING THIS 15" VENTED BOX PROJECT!
