Radian's T48 slim build

[Radian]

Side glued and screwed down. Technique applied here of holding off installing Panel 11 (mouth reflector) until the day of glueing down the final side panel. This affords some latitude to not only square up the mouth perfectly with clamps, but also allows that panel to "float" a little in its place while it cures, eliminating internal stress.

If there's ANY twist or bend in the mouth area paneling prior to setting down the final side, curing Panel 11 ahead of this schedule has the potential to permanently set that misalignment, no matter how miniscule, and can make squaring up Panel 10 to the side panel difficult at best.

Mouth brace installed and curing up.

Number 3 cabinetry assembly complete. Onwards to Number 4!

It has to be re-stated. The Titans indeed hold up to their namesake. These suckers are large, by any standard, and am solemnly reminded so every time we haul them out for pictures. I'm average height and a T48 stands right up to my chest. They simply dwarf the Klipsch La Scala.

Looking good! What is your use case for these Subs? What drivers are you using?

Very impressive work. Good planning pays off!

Well...that only took four years, but the cabinet assembly for this 4-pack is done. Onwards to finishing millwork, handles, hatches/wiring, first voice, filling/finish sanding, paint, and final assembly.

Great job. Love the old plan design.

Looks great

1.) What plywood are you using?

2.) What would you say was the most challenging part so far?

3.) Are you using a circular saw, or a table saw?

In the process of planning me t60 or t45 build and trying to prepare accordingly..

[Radian]

Thanks Bruce.

@Joman116
The plywood is 15mm 9-ply Baltic Birch.

The most challenging part for me, on this build, has been "time on target." ie. Actually getting my hands on the wood to push the project forward. Life happens, and at this juncture it's been a juggling act to keep priorities in alignment.

The most challenging part of any BF build is being absolutely fussy about the dimensions/placement of the bracing, which starts with a balls-accurate layout. Triple check those layout lines before cutting any wood. Cut the wood only to the layout lines from that point forward. Source the bracing dimensions from those layout lines, then "loft" them up squarely into position along the width of the cab. From that point, the bracing will either hold everything into alignment, or push everything out of whack. 1/16th of an inch here or there is all it takes to really get the other panels out of sorts.

I currently use a track saw system (shown on Page 1 of thread), which has been an exercise in compromise. I don't have my own shop. Just the garage which we primarily use for the cars, so no space for a table saw, which would be lovely for projects like this. When fabrication requires something fancy, I hit up the local maker-space downtown which has dumb-near everything.
