Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello All,
After a few weeks working on various projects since I finished the first pair of 186 horns I built for my son: http://forum.speakerplans.com/newbie-building-186-horns-finished_topic84892.html , this is time to be back in the workshop to start building the tops.

My choice is to build a pair of SMT 212 to fit 2 pairs of 186 horn.

I modified a bit the design to add handles, a curved grid like the one I used for the 186 and D rings, just in case of we need them to flown the tops from trussing.

As drivers, I selected these components:

- 4 Beyma 12MI100 http://profesional.beyma.com/pdf/12MI100E.pdf
- 2 Compression P Audio BM-D750 Serie 2 http://www.p-audio.co.uk/pdf/BM-D750.pdf
- 2 Horn P Audio PH-3223 http://www.p-audio.co.uk/pdf/PH-3223.pdf

Once fully finished, the system will look like this:

Here is my cut sheet for 3 square panels of 15mm 11 ply:
