Folded Horn Bass Box

Hey guys just wanted to post my newest Cube Audio project. This is a rounded horn bass box and amp combo that I am building for my Cube. Using a 8" shallow mount Pioneer sub and a Pioneer GM-D7400M Mono Amplifier. I chose to build a rounded horn to reduce wave distortion that can happen in folded horn bass cabs.

About the box:

The box is constructed from 1/2" ply and 3/4" bass wood home made ply that has been steam formed to mild steel forms. Used a conventional hand held steamer and built a steaming chamber out of my bath tub to steam the wood into shape. The project was started mid august, and it taking quite a bit of patience. This is my progress thus far as of Oct, 3. The checker pattern is done in stained balsa wood and has been coated in an 1/8th inch of poly resin. All sheets of Bass were coated in polyurethane and it is surprisingly rigid. 1/8" copper rods will deliver power to the sub form the amp listed above. The amp will be fan cooled with a thermal transistor controlled 12v fan in the end. The sub down-fires, and the box will port at the top of the box. Looking forward to completing the project and anticipate having about 2 months left until finished. The box will be carpeted in the end and should be no taller than 6" leaving plenty of room for storage in the back. I also will have two 12"x12" viewing windows on the top to view the amp and sub enclosure. I will post more photos as the project progresses and if there is any interest. Questions and comments welcome.
