I think the IDQ would be pretty starved for air in the Zerochief designed box, but it would be a better fit for your enclosure. We measured out Zero's box to be only .45 internally, and that IDQ sub requires .55 min for a sealed enclosure. It'd be a better choice for a 10" than say the L5 10" I was considering since it requires .66, but both the L5 10" and IDQ 10" are right here in terms of being at the bare minimum each sub requires for it's enclosure.

I have yet to finish my enclosure, but it's something I will definately have finished this weekend. I mocked up a cardboard version of Zero's box, and while I understand why for ease of removal, installation and production, I was surprised how much room was left around on the sides and front to rear fitment. You're lucky enough to have an enclosure that is made to the same dimensions as the factory DSP enclosure, so i'm sure you'll have a hair more internal volume than mine after it's done. Zero's box is way easy to make and since it's mostly square, it would have taken me no time at all. The cutouts i'm doing are leaving as little room as possible for gaps, having more angled faces instead of squaring them off, and it's gonna be a tight fit pulling it in and out. I've also taken a Sawzall (raised eyebrows from the neighbors ) and trimmed lips and edges from where the enclosure will mount so I have less cuts to make in the wood. I bought a few more cans of sound deading spray, so now it's just a matter of finishing the upper portion of the enclosure, glueing/screwing/routering/spraying it w/ rubberizer and shoving it in.
