tromprof Posted December 22, 2010 Share Posted December 22, 2010 I have enjoyed reading about the DYI sub builds and thought I would add my own. Over the period of several months I built this with lots of help from an engineer friend who has an incredible shop in his basement. Thanks to him the project took 4x longer and came out 10x better than if I had done it completely myself. The sub is Bill Fitzmaurice's "tuba table" and does a fantastic job working with the La Scalas, and has bass that makes my mighty K-horns seem somewhat lacking. I chose to slightly alter the plans by using 3/4 inch baltic birch for the exterior panels instead of 1/2 inch, which required reworking some of the dimensions so the important interior dimensions would be correct. Here are the build pics: The first cut! Quote Link to comment Share on other sites More sharing options...

tromprof Posted December 22, 2010 Author Share Posted December 22, 2010 After cutting doing a dry run to see if all lines up. I am glad I did because it didn't line up and I had to redraw my lines. Quote Link to comment Share on other sites More sharing options...

tromprof Posted December 22, 2010 Author Share Posted December 22, 2010 The gluing begins! We used PL adhesive as recommended. We also used "pocket screws" and then filled the spaces in with extra PL. Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted December 22, 2010 Share Posted December 22, 2010 Looks great! It reminds mo of my Tuba18 only larger. Quote Link to comment Share on other sites More sharing options...
tromprof Posted December 22, 2010 Author Share Posted December 22, 2010 Driver installed. We decided to go ahead and put it in before attaching the top so it would be easier to get to all the bolts. Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted December 22, 2010 Share Posted December 22, 2010 Do you only have one access panel? Will you be able to remove the driver if necessary once it's together? Quote Link to comment Share on other sites More sharing options...
tromprof Posted December 22, 2010 Author Share Posted December 22, 2010 Finished and in place! A nice water based stain, and several coats of a wipe on polyurethane. I also had a 1/4 inch glass top made for it. I am using a 300w "Bash" subwoofer amp with the crossover around 90htz and a Berhinger DEQ2496 to even things out. Music is fantastic, and it is really fun to turn it up a bit for movies. The Lord of the Rings was indescribable, the whole house was buzzing.

tromprof Posted December 22, 2010 Author Share Posted December 22, 2010 Do you only have one access panel? Will you be able to remove the driver if necessary once it's together? Yes, but it will be a pain. I wound up caulking all around the driver because of a leak so I hope it never becomes nesc. Quote Link to comment Share on other sites More sharing options...
tromprof Posted December 22, 2010 Author Share Posted December 22, 2010 3/4" baltic birch! That's one stiff sub! Stiff and heavy! I guess around 80 pounds. Quote Link to comment Share on other sites More sharing options...
Guest " " Posted December 22, 2010 Share Posted December 22, 2010 look good and well planed out. any idea on the performance specs. it look about the size of a lascala. congrats. Quote Link to comment Share on other sites More sharing options...
tromprof Posted December 22, 2010 Author Share Posted December 22, 2010 any idea on the performance specs. I wish I had taken a photo of the Behringer when I was doing RTA. It is very strong down to 25hz, falls off after that but I can still hear the 20hz test tone quite clearly. Quote Link to comment Share on other sites More sharing options...
