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!

Honey I’m going to go see a friend. Comes back with a banging system

[mmike]

Man I was nervous to build my own box but after watching this took away the anxiety probably gonna take me 2 weeks to make but it's gonna be worth it, thank you for posting this video you rock!!

[theurbanartist]

Man I have to give it to you, you’re one of the best when it comes to making boxes and the “how to demo”. I’m going to try & make my first box for two 10” shallow skars for my truck.🚪 A box is what makes all the difference

[Des]

He was so happy it made me smile watching it.

[JamesSmith-brgb]

The look on his face during that first listen made me smile so hard, would've made helping him build the box completely worth it

[MacNifty]

When you know that bass is hitting hard and you own it and it's yours at any time!! That's the best feeling in the world.

[patrickroberts]

Yo EXO!! I friggin love your vids kid, I just started getting back into audio systems and found your channel. I was a basshead back in the day, but I've been out for like 15+ years and I can't believe how far car audio has come!! Anyway man I was researching trying to figure what's what and who's who these days started watching one of your videos and haven't stopped for like 3 days! Top notch content and information. Keep doin what you do man, I'll be watching for sure, you got new subscriber here.

[kjmryanna]

It’s so amazing to see the smiles that bass gives a person.

Designed a sub around an e12 v3 for my best friend's son. He was very impressed with the result. So was I by the way. Its nuts what these new woofers are capable off.

[bailey]

Seeing how happy he was when first listening to the sub was such a feel-good moment for me. That's the kind of feeling we live for ya know? Those are the moments you'll look back on when you're lying on your deathbed. Makes me happy seeing you both se excited about this!

[wwmclawhorn]

Great video as usual! I wish Youtube and the people would see the time and effort it takes to do a video of this caliber. One of the best edit jobs ive ever seen and im so thankful i got to be a part of it! I am gracious and like someone said in the comments i am super happy!! Thank EXO and the car audio family for supporting such a great guy in EXO!

[ryandavis]

The satisfaction that you gave that guy was AMAZING!! I've honestly learned pretty much everything about box building from you and I hope I can make future customers as happy to hear my boxes jam like yours. Thanks for the new content.

[israelvega]

What a great job you did with both builds. The first build was the box that came out amazing. The second build is this video that is absolutely awesome, thank you bass head.

[orionfree]

Damn his friends face lit up like he was a child experiencing the first and best Christmas he could ever have experienced… awesome!

[jorgem]

28:41 I can totally relate to his smile when the bass kicked in. That's how I felt when I put my 20yr Fosgate hx2s in another box and realized how much better they sounded with the new box.

[BrittanyDeleon]

EXO MAKING DREAMS COME TRUE LOOK AT HOW HAPPY THE GUY IS! when I have the money bet ima be like that!

[simeonstala]

Your enthusiasm is much appreciated. Awesome to see you go from getting your first SMD sub to being a leader on DIY CA.

[RobHTech]
