Capsuleri asked me if I'd be interested in doing a tube sub with him. Anxious to try my hand at one, I agreed. His one criteria that made this one a little different was that he needed to be able to lay it on it's side or stand it up, depending on his final room layout and positioning. Several months of tossing ideas and drawings around and we came up with the "Capsuleri Capsule".
Needing a stable platform to use it laying down we decided on an octagonal endcap. A removeable base and legs would allow a vertical or horizontal position. The Tempest would also get a finished grill to protect it while positioned horizontally.
He wanted to line the interior with foam and thought some added bracing would help keep the tubes shape while laying down.
We decided to use maple to make the caps and legs, as he wanted to use a rather nice fabric he found.
He had the tube professionally upholstered using 1/4" foam with the fabric stitched around it. Unfortunately, the upholsterer had no clue how this sub would come together, and cut the fabric kinda short. We decided to use a recess around the caps to trap the fabric and foam, to hide the fabric edge.
Here's the shot of the back of the sub. Notice the heavy duty binding posts that are wired to each voicecoil.
And here's the front.
It's a sealed Tempest, 9 ft^3 fully stuffed. It stands about 58" tall and amazingly, he managed to fit it in his car to get it home, although we had to remove the base and legs.
