I made a 0.5 ft^3 sealed box to test out my 8" woofers that I ordered, and if anyone wants it I'll sell it to you for cheap. I didn't make it look pretty, the cuts were done pretty quickly so it's not a perfect cube but the inside is fully caulked and there are no air leaks. 3/4" MDF, 11"x11"x11" external dimensions.
