I wanted to show my new 8 foot long subwoofer I recently built using 4 of the Obsidian 18" drivers for my Great room system. I have a 110" diagonal projection screen that is 8 foot wide so I designed the subwoofer to fit under the screen and look like a piece of furniture and have a high WAF factor. This is what it looked like with just the screen on the 20 foot wide wall.
I built it in two pieces in case I needed to break it down in the future to move it.
I used a 8 foot long and 25" deep walnut butcher block top and used those dimensions as the basis for the rest of the cabinet, going with a ported design tuned to 20hz for each 4 foot long cabinet
I went with the Watco Danish Oil to end up with a low sheen to prevent reflections under the screen. I used matching walnut corner pieces and then thought the ends would look nice with black mirrored plexiglas. I wanted to have a one piece front grille and used some c-shaped aluminum channel for the grille frame.
I'll use a second post for more pictures
