Next up, Lil Wrecker

  First off, thanks to Lil Mike at the AVSforum for another great design.  Mike designed the Cinema F-20 and now it's big brother the Lil Wrecker.  For comparative purposes, the F-20 is a 20 cubic foot refrigerator sized sub.  The Lil Wrecker comes in at 29 cubic feet, is louder and goes lower.  It's right at 6 foot tall (5' 10" plus feet) and I'm guessing  well over 200 lbs using 3/4" birch.  MDF would have definitely been weight prohibited.  The box is tuned to 17 Hz so in room should be good to around 14 or lower.  Another difference between this and the F-20 is that the F-20 is a front loaded horn and this one is tapped.  The driver is a 15" Alpine that will be powered by a bridged Crown that should give it a clean 1200 watts.

  The build.  I'm just about done and only have the Neutric connector left to install.  It'll take me a while to post pics so I thought I'd start.  I hope to fire it up this weekend.  I appreciate forum member mxr dad for entrusting me with this build.  It's always nice to build something different.

 

I knew this was going to be big when the cut sheets called for 4 sheets of 4x8 plywood.

The next flare.  One thing I had issues with on this build is a bit of warpage on the panels as they were so long.  MDF doesn't warp.  These panels were so long that I had to really work to straighten them out to keep things square.  Most times I would just have to put the panel on and pull the warped section when I attached it to an adjacent panel.  I like to keep the panel tolerances to 1/16" and this one really challenged me.

And love the name. Lil Wrecker. Could stand for your back while lifting it, or pictures wrecking off the walls, etc. I'm just thankful to have an understanding wife so it isnt a marriage wrecker. LOL. 

 

 

We joked as I nick named this thing the "Hernia".  Once all the panels were on it just seemed fitting.

On this picture you can see the outside starting to form.  t looks like I mis cut the sides as there's quite a bit of overhang.  That actually was planned.  It's much easier to cut the end panels long and then use a router with a flush bit to trim them.  It's a lot easier to do that than try and get them perfect on the adjacent boards.  It's a real time saver and saves a LOT of time that would normally be sent sanding after the box is together.

Carl I looked at how fast the build was going at it only took a few minutes to read all the comment and look at the pic's.  This reminds me of Home Time, the DIY home guys.  They can build 1/2 a house in a half hour.  I just thought you would enjoy a little humor with this build.  Nice work!
