Dayton Audio 4" Subwoofer enclosure

The walls are 13mm and i made the volume at recommended for a vented enclosure excluded the speaker. It's built with tongue and groove for easy and strong assembly. Use low viscosity glue. The TCP115 is a very good woofer for the money. I added the link for the parts and spec-sheet. M4 thread and countersunk M4 for the cover-ring.

 I hope you like it.
