THe boxes aren't "standard". Watch the vids on the site, they are a different design than what you normally see in a ported box, and they work a hell of alot better than the "typical" ported box. SQ AND SPL are both improved by design.
Excuse me for not needing some oddball alignment to work well.
Would it sound better to you if it were the magic "TCB" box with 40 feet of port that gets exponentially bigger then halves in size until it comes out at the exact square of the area of the sub? Would you then be satisfied that its just flat out louder and cleaner than nearly any other box out there, period?
The future = meter at the headrest.... IMO nothing else really matters.

And in that event, you won't see many 50hz+ notes doing great numbers.
