Sub Box Help

[pwmin]

Since my MTX RT12 seems like it's going out and is in a generic truck box, I'm wanting to build a box correctly for the RT10-04 I have sitting around that I forgot about. The amp is a Lightning Audio B.200.2. I'm just going to go side-fire and I'm just looking for a box w/ no angles. I don't necessarily need dimensions as I can figure that out, mostly just cubic inches.

make any headway on this? My sub is starting to sound like shit off and on, but it's getting more frequently bad.

Online calculators and manufacturer specified sub boxes are beyond terrible. They make those to suit the vast majority of people who just want loud and to save themselves from warranty returns.

It was my wife's birthday yesterday so I didn't get around to it, but I have time today so you'll get a proper sub box design by tonight.

that's fine. I'm away for work and won't be back until late thursday anyway. I was hoping I would be back tomorrow, but no

Alright, finally got some time to work on this. Sealed is not an option as the sub is made for a ported box, so you'll have to go vented. Unfortunately, it also needs a bit of a large-ish box.

You'll need one 4" port at 17" in length. Use one of these and just glue it all together, or use 4" PVC pipe. This kit will give you a port length of exactly 17":

NET volume is 1.85 cubic feet
Port displaces .14 cubic feet
Sub displaces .08 cubic feet

Total GROSS volume is 2.07 cubic feet. Its bigger than your other box, but this sub doesn't play very nice in smallish boxes and unless you're willing to give up some of that bottom end you get in dubstep, rap/hip-hop and techno, it will have to be this big.

One box example would be 15" Height x 15" Depth x 21" Width with 3/4" MDF. Fire the sub out the front of the box, and the port out the side. I think you will be thoroughly impressed with the way this box sounds. I can get you a different box dimension if you'd like. I would recommend some bracing or a double thick baffle. You can use 1" coat hanger rods or 2x4s.

Image models are attached with cabin gain included.

Thanks, man. I'll check into the dimensions and see if they'll work. Hopefully I'll be able to start on this Monday as I won't have any time this weekend. I'm willing to give a ported box a chance. I actually do remember now trying to make one once but it was a miserable attempt as I had absolutely no clue what I was doing, lol.

Well, if you want to use this sub, its going to have to be a ported box. It will bottom out in a sealed box on low notes. I do think you will like it though. The model looked real nice.

looks like the dimensions will work. It won't be able to find under the stb, but I can just move it back. If I make it shorter, I'll have to make it longer and it's already long enough. I just hope I can still get a larger bin in the trunk, but I'm pretty sure I still would be able to.

Well, being a 12" sub, it needs to be a tad bit taller anyway. Looking forward to seeing this box built.

It's a 10" sub...the 12 is going bad
