Looking for a double stack enclosure under 8.75" wide

Hey yall, so I’m trying to do a build with some leftover parts and I need a double stack enclosure that’s at most 8.75" wide, any ideas? I’ve been debating grabbing a tomiboi enclosure and appropriating it to make it fit but I’m also curious if there’s an off the shelf solution that would work. Any ideas?

I’ve made a few of my own enclosures lately out of fibreglass, as well as doing some deck routing and reinforcements, and they’ve been relatively successful given I’d never done fibreglass prior.

If you’re gonna make it fit anyway, why not just start from scratch? Urethane foam works well to make the basic shape.
