Seadoc Posted July 25, 2021 Share Posted July 25, 2021 Started on the mid lenses for my La Scala I builds (2 pairs). I am using 1/8" HDF to form the K-400 mid lenses. Created computer "bent" interlocking forms then "unbent" them to make my notched patterns. HDF was easy to work with and was very similar to the formed plastic thickness of newer lenses. Using info from PWK's 1963 builds and help from forum regulars on dimensions. I am adding bracing/stiffeners to the lenses and the cabinets to upgrade from the 1963 build issues. Planning on testing soon at the Herrick Sound labs at Purdue to see where my build skills put these. A work in progress, updated coming. 5 Quote Link to comment Share on other sites More sharing options...
carlthess40 Posted July 25, 2021 Share Posted July 25, 2021 Well if you build some spares , let me knowI really like the looks of them. Even if they don’t test out the way you want them toSent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

Seadoc Posted February 6, 2022 Author Share Posted February 6, 2022 More picture updates. CNC, jigs & sleds, fixtures, 100 tooth blades, and a full-time shop vac. 4 Quote Link to comment Share on other sites More sharing options...
Marvel Posted February 6, 2022 Share Posted February 6, 2022 That's really nicely done. Thanks for posting the pics of your work. A word of caution... The T'nuts/bolts on the left and right edge of the baffle will almost impossible to put in and tighten or remove once the cabinet is built. The slope of the 'doghouse' and woofer frame make those two locations hard to get to. Klipsch only used four to secure the woofer to the baffle. And make sure your T-nuts are on the correct side when actually assembling the cabinets 1 Quote Link to comment Share on other sites More sharing options...
RRR Posted February 6, 2022 Share Posted February 6, 2022 Looks great, run the brace all the way across the cabinet. leave yourself room for woofer access of course. Quote Link to comment Share on other sites More sharing options...
Marvel Posted February 6, 2022 Share Posted February 6, 2022 Is this threaded for the driver? Where did you get them, or did you make them? Quote Link to comment Share on other sites More sharing options...
Seadoc Posted February 6, 2022 Author Share Posted February 6, 2022 @Marvel I originally looked at a PRV Audio adapter (ADM25-50) but the overall was, in my opinion, too long @ 3.125". What I used was a Luse adapter from ZXPC, threaded for 1-3/8-18 and about 1" depth. Super solid and no midrange driver cantilever concerns.

Seadoc Posted April 17, 2022 Author Share Posted April 17, 2022 Installed some solid white oak verticals that I ripped in-lieu of the 3/4" veneered glued verticals that seemed too weak. Added some extra items for smoother sound wave direction (corner 45's and split side supports) IMHO. 4 Quote Link to comment Share on other sites More sharing options...

Seadoc Posted April 28, 2022 Author Share Posted April 28, 2022 Minwax True Black stain done. It was motivational to listen to Back in Black. Minwax Warm Satin sealer next. 3 Quote Link to comment Share on other sites More sharing options...
Marvel Posted April 29, 2022 Share Posted April 29, 2022 Those are looking super. Wanted to remind you, as I can't tell from the pics. Looking at this one, if your t-nuts aren't pushed in from this side, your woofers will fall off the baffle (unless you made a double layer to hold the nuts in place).
