I've covered all of this. You can make the box any size you like as long as you keep the same tuning. Just like a sealed box, just use eq to get it where you want it. I only used the size because it provided an easy comparison to a known product.
I am not ignoring vent noise, in fact I've simulated the hell out of the situation with several different programs.
Pipe resonances have been shown IN EVERY SIMULATION done by both you and me to be a non issue, less than 1 db ripple.
I know you don't think the compromises are worth it, that does not invalidate the simulations. I agree that compression testing will very likely show a situation worse than the simulation but no where near as bad as you seem to think.
The normal course of design for ANY design is to simulate with acceptable velocity limits as predicted by the t/s simulator, 10 or 17 m/s are popular limitations set forth by diy'ers. You may or may not want to check the result with Flare It at that point. This is what everybody does all the time, how come it's not valid in this case?
I seriously don't care if the design is worth it anymore, I'm only arguing that it will work as simulated, just like every other sub works as simulated.
