Hi Boscoe - The Cubo series is a group of "Hybrid" cabinets that can only be designed in ACABAK. They are not "Tapped Horns" and HornResp can not be
used to simulate their response.
Due to transport (and weather) restrictions I do most of my measurements indoors (450 m^3 / 16,667 ft^3 room). As you know these measurements will excite room nodes and thus alter the response of a given cabinet.I don't understand why you show plots of the difference between BRs and Cubo cabinets
I always strife towards higher quality measurements. I do think the information given, for a diy-plan, is quite up to standard.Could you provide actual SPL/Freq plots?
Sometimes I'm persuaded to give HR input parameters for Cubo 15 or Cubo 18. Always through email and at a personal level though.Could you show the HornResp input screen for one of your cabinets?

The 18Sound, 18LW1400 in a 175 liter cabinet tuned at 37 Hz is a basreflex cabinet that could be a standard. As most people are familiar with the performance of a (good quality) 18" basreflex, I do think it's a pretty straight forward comparison.
Apart from that, without a calibrated mic, it's perhaps the closest way to come to an insight in meaningfull sensitivty figures.

Bitzo @ freespeakerplans did post two pdf's to arive at input parameters for the Cubo series:
