I have never shared any of my builds on here so I figured I would share my most recent box build. Its nothing too special though.

The goal was to make a good sounding daily ground pounder to make it easy to resell locally.

It comes out to 2.98 cu/ft tuned to 31.66hz. It sounds great and plays well into the mid to low 20s. The sub is an MTX Thunder 8000 15 svc 4.


On a sidenote, I picked up these clamps halfway through the build for stupid cheap. You can get them for $10.40ea before tax if you use the 20% off coupon thats distributed practically everywhere. Oh, and they have a lifetime warranty. http://www.harborfreight.com/hand-tools/clamps/58-1-4-quarter-inch-aluminum-f-style-bar-clamp-92490.html

Not even any haters?

I know its nothing special that will rattle the pictures off your neighbors walls but where is the love :(

Apparently every build here has to be DD or Sundown or multiple 18s in a wall or something expensive and massive to tickle everyones jollies.

I like Harbor Freight. :p:

Me and my buddy got a 6.5 hp engine for a go kart from there for like $80...they have some pretty cheap stuff there.

Haha I also dig the box!

I kinda of stole the idea from a build I saw on here lol. I forget who it was but they did 2 dd 1510s in a single cab truck.

I've had a lot of good results with their older stuff. There's a lot of it that pops up for real cheap on craigslist around here.

I think this is my favorite MTX sub so far. SQ far exceeded my expectations. I wish I had more power to give it- I'm giving it 534rms before rise. Its got a 2.5 in 8 layer coil rated for 500, so it will easily handle more.

Think I gave $50 bucks for them.

Not a bad looking box. If you plan to sell it locally it would make a much better box than a nooby prefab for someone. Plus make some monies too.

A year ago I picked up 3 6000 12s for $60 and made a sealed box for them and sold them to a friend. I was surprised how loud they got for only 9.4mm of xmax, they were getting 1100 before rise.

Yea thats what I have been doing. Its a nice way to make a few extra bucks and gain experience. I got 4 10ft long sections of thin wall pvc for free so I figured I might as well start using it haha.

Yeah the more boxes you build the quicker, easier, and better the boxes become. I still learn and improve and I have build a ton of boxes.

I like this man, nice and clean. What type of bolts did you use for binding posts?

1 1/2in long 10-24 pan head machine screws and wing nuts and some washers. Basically something that would fit through the ring terminals I had, with washers to provide solid contact throughout.

does the type of metal the bolt is matter much?

Possibly, but not from what I have experienced. DMM dc resistance readings are the same when touching the leads directly to the woofer compared to touching the leads to the wing nuts outside of the box.

Box looks good. Curious as to why it's clamped after you screwed the top on? Harbor Freight FTW....
