Hey all -

     

     This is my first personal build thread!  There will be more builds to come after having a good experience so far with this one.  As the title states, I am building the 'Marty-Cube' and using a Stereo Integrity SI18HT subwoofer, paired to an inuke 3000dsp.

 

Here are a few pictures of the progress!

 

Mocking things up:

 

 

 

Back, bottom, and sides complete:

 

 

 

 

 

Couple pictures of the port bracing.  Also - You can see I used a sealer on the outside... this is likely not necessary for the majority of you all, but the table saw i was using was SO shi**y that a few of my cuts simply didnt come out as square as intended.
 

 

 

 

 

 

 

My spare room is getting to be a mess with all of my speaker gear haha.  Almost finished!

 

 

 

 

 

 

I will update this post with the cut sheet / more information and also a link to the thread I got this inspiration from!

Big thanks goes out to everyone on this site... you have all been a huge help!

Thanks!  BTW- this is Ryan, just changed my account.  My jasper jig was supposed to arrive today but I got an e-mail saying it was delayed because of the weather.  SOB.

 

I REALLY want this completed by this weekend because the wifey is working so I want to be busting out the basement windows all day ;)

 

I will have to crank it real loud and walk outside the house to see if it is very noticeable to the neighbors haha.

It does look awesome, are you building the same Marty cube as chaluga? Are you going to coat it with duratex?

Thanks for the links guys. I have had a hell week at work. I will organize my post and include the links and more info such as my cut sheet and tips and stuff I picked up along the way.


I HIGHLY recommend buying a pre made one if you are not a fairly skilled woodworker. I am glad I still have 10 fingers after making a few boxes now lol.

I didn't get much done this weekend frown.gif I was hoping to finish!

I am recessing the baffles 3/4" so I can add a grill and have that sit nearly flush.

I will next add the port rear and all of the bracing. Everything is coming along fairly smoothly, all things considered. I can't wait to fire this puppy up.

I am adding some wood (not mdf ) to the back of the baffle to add additional material for the screws or t-nuts to hold to.

Anyone have any good suggestions for what to order to properly secure this driver to the baffle? (Preferably from PE)

#10 by 1-1/4" screws do just fine. I left the original gasket on. It hides the screws. If you need to take the driver out then do it. When putting it back in spin it and find a fresh spot. The only way you would need anything else is if you are taking it out a dozen times

Ok. I hope to never have to remove it haha.

I wish I had simply ordered one from you... The table saw I was using was so janky a lot of my cuts are 1/16 -1/8" off haha. Makes for a lot of extra sanding, sealing, and wood filling. When its all said and done it will be so worth it.

Haha.. I am already half regretting my decision of the 18" ... I am in love with my friends 10" !! My pictures on my walls will need some felt strips or tacky stuff on the back of them. Almost killed the fiance Friday with a decoration falling off of the wall! Talk about losing a few notches in the WAF.

I can't wait to play bass I love you though wink.gif

Welp - stopped at Home Depot to grab some screws. The guy recommended the maroon package panhead 'sheetmetal' screws, and I grabbed a set of the spax. Both #10x1.5" ... Which should I use? At first I was thinking panhead but now second guessing myself.

I believe those Spax screws may slip right through the holes in the basket. I am also using Spax screws on my SI's at the moment, albeit longer ones, and I had to use washers. You may find that it's close with the panhead screws you bought as well.

Flynnr, I used Hillman Pocket screws (#42170) on my build, they worked great. Black Phosphate in color. I bought long ones since 4 of the speaker screw holes lined up with my front to back braces.

Couple of progress pics - I primed with shellac based primer (3 coats, sanding between coats) and have done 2 coats of black latex paint using a 4" roller.

I also glued pieces of real wood to the back of each mounting hole for the sub... I'm hoping this helps prevent the screws from stripping out as easily as if it were straight mdf.

This weekend I will be adding the finishing touch: a grill. I picked up some speaker grill cloth and will be trying a few different grill options as I have a lot of spare wood.





Teaser ( only because the lighting is so poor you can't see much anyways)

Flynnr,

that is one hell of a nice looking sub. congrats!

I'm building one too for my HT room, along with a vertical full size. Seeing your finished sub though, is making me want to pick up the pace!

Enjoy it, and definitely post your thoughts after spending a bit of time listening to it.

Until my 2 are done, im living vicariously through you.

p.s - your whole room looks pretty nice as well.
