I made a Enclosure/Satellite speaker for Dayton Audio DMA80-8 3" Dual Magnet Aluminum Cone Full-Range Driver with Dayton Audio DMA80-PR 3" DMA Series Passive Radiator. The enclosure volume is made for vented to the spec. The walls is 8mm thick. It's built with tongue and groove for easy and strong assembly. Use low viscosity glue. M4 thread for the speaker and countersunk M4 for the holder.
