As some of you know my buddy Chris got a 21" sub at
's get together last weekend. He currently has two systems in his house. One is using a SVS PB12-NSD, and the other has two 10" Polk Audio subs. He was planning on building a UM18-22 to replace the SVS but of course he has been waiting for months like everyone else. I had brought it to the G2G to get a taste of crazy home theater bass, and to hear some DIY speakers. Like I said he was already on board with going DIY, but heating Mikes set up and the various DIY speakers really set the hook.
Then of course he won the 21" sub from Matt, and we were off!

Thing took up like my whole trunk!
Next to that puny SVS
So after talking with
he got us all the specs and also suggested some boxes for this beast. Here is the model for what we ended up with.
The box is going to be 30" wide, 36" tall, and 30" deep which puts it at about 16.2 cubic feet. We are going to run three 4" precision port kits, which puts the tune about 17.77 Hz.
So because I am a nerd, I drew up the box real fast
Once we had the box design locked in, Chris ordered up everything else needed. Power is coming from an iNuke 3000DSP, got the ports, and some SVS sound path feet since this sits on a wood floor.
Now its time to start the fun part. First up is getting material.
Time to start cutting!
Here is the front panel, just a little guy
We did some routering to the edges so that there is a lot of surface area for the glue, and then Chris got them dry fit.
We were pressed for time today, so that was all we were able to get done. It didn't help that I made a couple mistakes
I am going to try and get over there tomorrow (well later today at this point) and get some pieces glued together. We are pretty excited to get this thing up and running. It will be the craziest sub that either of us has ever had or built. Should be pretty bad ass!! Also the SVS is going downstairs where the Polks are, and the Polks are going to the garage for when we are working on the cars
Stay tuned for more!
