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 ...

PM sent.

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.

Here’s some additional advice. Now that you’ve built your version of the most kickass system, (which certainly looks the part BTY :wink:) try and spend some time reading prosound books and applying that knowledge to dial it in and get it sounding exceptional. Take the time to setup, measure , and sa...

Eminence KL3010LF in a standard width T24 is a wicked amount of output for its size. Have you done any actual testing with it? Nope. But in the past, I’ve run an entire block party on a pair of 8” loaded Auto Tubas that had the neighbor half a block down the street from us demanding that we turn it...

Specific phenomena to avoid would be the all-to-common situation where the subs are taking a giant crap all over bottom octave of the mains. Once you discover what that sounds like, you'll hear it everywhere. Which is typically from choosing the wrong filter set points, choosing the wrong filter slo...

Optimal crossover freq for the subwoofer hand-off is more often than not, situationally dependent. Measurement is highly recommended. Could be as basic as any flavor of SPL meter, a voltmeter, notepad, and pen...all the way up to a formal Smaart rig.

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.

Number 3 cabinetry assembly complete. Onwards to Number 4!

Mouth brace installed and curing up.

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 i...

Welcome back Kent! All great ideas. LAB drivers, in any flavor, are excellent performers. Can't wait to see what you come up with.
