All Volcano speaker box enclosures are guranteed to stand up to competition. Every enclosure is hand built out of 3/4" High Density Industrial Grade  particle board. Every enclosure is assembled with 1/4" crown staples, and glue is added at every meeting surface to bring you a box that stays together. Our boxes are dadoed and jointed, this reinforces each board and makes the box stronger as well. Enclosures are carpeted with the most durable carpets available on the market. For more infrmation on the materials used and why:
