There are some tweeters from Scan-Speak and Tymphany, all of which share the same front panel. One or the other of them also measures itself excellently on the P-Audio (PCT-300), or Monacor (WG-300) waveguide.
In order to connect the drivers cleanly with the sound guide, an adapter plate milled in CNC was created after many test series, which allows simple and very precise installation.
The following tweeters are suitable for the conversion
3D printed adapter plate in the shop
With a jigsaw, cordless screwdriver, router and the following step-by-step instructions, building the adapter plate yourself should not cause any problems. It doesn't even have to be measured 🙂 Let's go ...
- Print out the PDF (included in the respective building folder) using Acrobat Reader (choose the “actual size” option!)
- Size check: Outer diameter 120mm
- Glue on a 9mm thick piece of MPX / MDF / screen printing plate (spray glue / glue stick ...)
- Drilling the holes => upright drilling machine is an advantage!
- With the circular milling device (each speaker should have one) 3mm deep to appropriate mark milling (D67mm)
- Use the jigsaw to saw the inner hole and saw off the plate in the last step
From the practice with the "home remedy method" another additional tip from Thorsten (www.felbi.at)
If you glue your artwork directly onto the substrate (eg MPX), you will have the difficulty to get it down again later. For visual reasons, that bothered me and came up with the following idea: Before you glue your artwork on the MPX, just past the MPX with tape. Now the artwork will be cut to the size of the MPX board. Spray glue is then sprayed onto the package tape and allowed to dry for about 5 minutes (Note the spray adhesive is not on the paper spray!). Now the print template can be glued on.
Once all drilling and milling work has been completed, the package strap can easily be pulled down again from the MPX board.
First, the front panel of the tweeter must be removed. On some models, this is easily fixed with a silicone-like adhesive. In this case, use a large slotted screwdriver to "pry" it up discreetly as shown in the following picture. Work slowly and evenly. The screws on the front panel should of course have been loosened beforehand (TX10).
Dressing the waveguide neck
The adapter plate is placed on the sound guide and the neck is ground flat with circular movements (⇒ dust mask).

You do the conversion on your own responsibility! I accept no liability. Possibly. you lose your warranty claims during the conversion.
I made a lot of changes and nothing ever happened. I think the instructions are pretty "foolproof" 🙂
