💡THINGS COVERED💡
1: Quick Check-In
- Going over the all previous steps to get to this point, plus touching base on the carriage bolt situation and thread locker. Because I didn't want any exposed threads underneath, the plans ended up changing to fix that.
2: Mid Build Weigh-In
- Keeping track of how heavy the setup is really makes things fun. Without knowing exactly how much weight has been added due to the heavy sound system and other aftermarket upgrades, periodic drop ins to the public scale help keep us informed.
3: Finishing Front Welds On Baffle
- When originally designing this subwoofer layout, I made sure to leave space to accommodate the angle iron that's mounted directly to it. Now that's it's final, the last beads can be laid down super thick without getting in the way of the flat mounting surface for the large wooden panel.
4: Installing Front of Enclosure
- The largest section to the outer layer of the cage gets attached first. Building it from the outside in keeps important lines visible, like markings where the steel frame is installed. Tracing around each of the tubes ensures the screws bite nice and strong.
5: Filling Inner Caged Squares
- To improve strength and increase wall density, every single square between metal framing gets filled with more wood. The plywood used is extemly rigid and stands up to abuse from loud stereo systems really well. Used a Harbor Freight chop saw to cut all the pieces. Best combination I've found for this are torx head construction screws, wood glue and tons of Loctite PL Max adhevise.
6: Making Floor Brackets
- Because standard pipe flange mounts won't work in this setup, a custom made bracket design for all 12 verticals was the only way to complete the job. Made them from 3" flatbar, cut to size on the abrasive wheel, drilled and countersunk for hardware, then rounded over the sharp edges and corners on the new benchtop grinder.
7: Marking Center of Plates
- By using a small plumb bob hanging below the cross supports on the baffle with magnets, precise measurements and brace spacing is easy to draw out on the floor by hand. It makes positioning from above dang near perfectly straight!
8: Flush Trimming Brackets
- Figuring out how to keep the enclosures bottom flat and smooth was also a tiny challenge. With a fresh mortising bit installed in the mini router, resessing the attachment points 3/16" wasnt hard at all for it. Very powerful tool!
9: Scoring Adhesive Fissures
- With 12 18 inch subs playing at full blast, there's going to be tons of built up sound pressure from the subwoofers flexing. So to help prevent any screws from pulling out of the holes, several grooves get cut into the bases to hopefully act as roots for more holding force. Each was sanded / grinded down to bare clean metal before putting in.
10: Attaching Steel Base Plates
- Gluing and screwing the brace plates down was a whole big long step in itself. Following a pattern of all 4 corners first, then torquing the center screws with a heaping pile of adhesive squirt in all the sockets . Hopefully this'll make things even stronger than normal.
11: Welding Vertical Braces
- To avoid burning the precious wood underneath, all welds against the floor plates needed to be 3 second bursts. Otherwise the scorching could possibly pit the mounting surface. I made 8 individual passes on the welder to create an evenly spaced line of welds around the base of the 1" tube. Then filled in those gaps with another 8+ welds to tie everything together.
AND THAT'S THAT!!! 😎
