DML SPEAKERS MK2
these are an improved version over my previous speakers using a carbon fiber plate behind the driver to improve frequency response and sound quality without the need for equalization.
These use the Dayton audio DAEX25FHE-4 transducers
The drivers are superglued onto 100x100x 2mm thick carbon fiber squares which you can get from ebay or aliexpress and attached onto 5mm thick 20×30 inch foamboard sheets using 3m plastic screws and nuts do not glue the carbon fiber to the board. I used plastic washers made from toy boardgame discs to stop the foamboard from crushing.
The panels need stands to hand them on- I used string glued on the back of the panel hung on hooks
I found carbon fiber excellent since it is very light and does not flex lthis is needed for dispersing the sound over the panel.
Tips & Tricks:
you can cut carbon fiber with a hacksaw if you cant get the right size boards.
These sound excellent and are a big improvement over my previous design and can be made easily for low cost.
