Researching various subs, I bumped into the Renkus-Heinz BPS 12-1 & 12-2.
They call these 7th order bandpass. I Googled this, but it's not clear if there actually is such a thing, or it's just a variation of 6th order.
So, is there such a thing?
The reason I'm curious is that it's fairly well established that 6th order BP suffers from bad transient response. Yet, the RK data sheet says, of this particular design:
"The improved loading of the high-order bandpass design produces extremely "tight" bass with excellent transient response ."
Can this be true? Is it a design to consider?

The cutaway image looks to me like that of a slot-loaded vented box. Kind of a stretch to call it a "bandpass", though technically I suppose it's correct as the slot-loading will reduce the HF output from the driver. But 7th order? Only if there's some sort of inductor in series with the driver...
