A few more minor updates to add all the rebates, pilot holes for screws (90 degree joins only), handles, pole mounts, skids, grill supports, dish for speakons etc

Next step to get the cut sheets into dxf format and get one cut. Hopefully progress may speed up a bit.

Mono test but will be stereo.

Yeah - i am getting a box cut at the moment cnc should be done in a couple of days and can then see if i made any errors 😵. After that i can share the 3d model and dxf files.
Feels good to finally see something solid!
Citronic QP2320 4x450 4ohm for tops
hp-3200 2x1600 4ohm subwoofer
High freq 70-80% no clip
Low freq used 50-60% no clip
Driver 2x BWP18 1500rms 4ohm
Cheap product and unsure longlife for tapped horn pushed.
120db peak and 110-115db continuous was impressed by the air pressure at the mouth of the horn being so high. someone told me that he heard the music from 1 km away and someone closed told me he felt the bass how is going far away. just two bins..
Anyway, I got a clear and deep sound beyond my expectations.
Wow!! Congratss 🎉
Looks great!!!
I think you can't wait to hear the BeasTS !! Alive!!
Any chance you can share the 3D model and dxf files? Build is looking great and i've always wanted to build the mk2's
Finally got around to tidying up the files. There's a 3d model in Fusion 360 and drawing files for cutting in Rhino 3d and DXF. It all fits on 2 sheets of 18mm 2440X1220 ply.
All the files for cutting have layers for CNC operations and bevel cuts as needed. And there are layers for the pole mounts (Penn-Elcom M1562) are flagged as optional so you can delete them if you don't need them.
There is a third sheet saved in the folder called TH18 Sub Extras - this isnt needed but has template jigs to cut the rebates with a hand router for the pole mounts and skids (on the flip side of all the other rebates that will be CNC'd) there's also skids and a few spaces to help when assembling the bracing.
I'm not sure the way i did rebates on the bracing was optimal and it needs to be assembles in a specific order so make sure you dry fit everything and work it out. I'm getting a second one cut so will try and make a better build log.
