I posted a while back about building a sonotube, (which I may still do once my theater is done) but for now I wanted to build something a little smaller for my living room. I decided on NEODAN's easy button max design for the time being. I have no previous woodworking skills, but I'm fairly handy. It will be powered by a EP2500. I've read through NEODAN's thread a few times, but I don't think I ever found what the final tune was for the box in it's MAX configuration. Anybody know?

So, it has been a few years since I worked with MDF. I forgot how much I hate it. :) I really should have had on a mask. I used a table saw to cut up 2 sheets of 3/4" MDF. (bonus! I got home and looked at the receipt, they charged me for 1/2" mdf)



I am not known for having a neat work area. Plus I'm in the middle of replacing all my windows, a little but of siding, and new trim on the inside. All while building this sub and trying to get my theater done in the next couple years.



Gen II Maelstrom X I just got.



I plan on getting a jasper jig for my future projects. (When I'm done with everything else I'd like to build some statements for my LCR.) In the meantime, I just built my own circle jig.



Of coarse I broke my cutting bit with only a little but left to go. I think I may have tried to cut too much. I did 2 passes and should have done 3. I finished the cut with my jigsaw.



I don't have a lot of clamps, so I had to make due. This is sitting out in my driveway right now.

I'm going to build the exact same thing, with an EP2500, Reckhorn SSF @ 12Hz (lowest setting), and Samson S-converter (gain) in the future. I have everything, but not the space nor time to complete the build yet.

Keep us posted! Round all the edges of the port. :)

I just ordered the 1.25" roundover bit last night. I also ordered a 5/8" roundover for all the edges. I plan on finishing this in a DIY bedliner since eventually it will be in my HT behind a AT screen.

I haven't decided yet on a SSF and EQ. I'll probably end up with a BFD for eq, but still wondering about a SSF.

Today's progress. I can't go much further until I receive the large router but for the port edges.

Gluing the port runners to the bottom.


Gluing the back on.

Last 2 pictures. I can't do anything else until I get my router bit.

Glued up one more side.


Couldn't help but dry-fit the rest of the pieces except the one side and the front baffle.



The tuning will be in the low teens. I thought I read somewhere that if the tuning is extremely low a SSF isn't needed. Is that true?

Mike is right. The idea is that the tuning frequency limits excursion saving the sub from bottoming out. However, when you go below the tuning frequency the sub unloads BAD. The reason people say a very low tuned sub doesn't need a SSF is because when you're tuned to the low teens there isn't much sonic information below your tuning frequency to hurt the sub :)

I got my router bits last night. I put on the 1.25" roundover and man that thing is freaky. I did one edge before work. I felt like I was holding a spinning blade of death! :dizzy:

Be very careful with that and keep a firm grip at all times. Slow your speed down. GL.

Almost done! All I have left is the front baffle. I'll take care of that tomorrow. I just ordered a EP2500 and a Mic2200 from B&H. I will eventually get a BFD, but since I'm not ready for it to go in it's permanent place, I'll just wait and save the cash. Here's a pic after I just the top on. On a side note, I tried to move this around on the horses....this thing is crazy heavy. Not including the 50lb driver that will be in it.

I had my sister try to get my Mal-X box in the house while I was out of town. She called me and wanted to know what was in it. She had almost torn one seam all of the way, and there were holes in the box where she was trying to get it into the house.
I feel bad for having her get it :T

Yes, I know...I'm a bad brother.

Let us all know how your build turns out, and it looks good. Hope you enjoy it!1

Nice work Andy! How about some pics of that mega roundover bit and the work you did with it?

Also, keep us updated on the setup once you get it going, I'm very interested in the MIC2200, and I think I will be adding one of these to my system eventually. Do you have your setup parameters in mind?
