Each weight raises moving mass, which drops free-air resonance and raises the driver's total Q, and Helix publishes a different recommended sealed volume for every setting to keep the system in hand. This cabinet is offered in no added mass, +1 mass ring and +2 mass rings, 13 to 25 litres of Helix's own recommended volume, and across those the system Q works out at 0.70 at the base setting and 0.75 at the top of the range offered.

The 0.52 cu ft figure listed is what we actually cut, which is 0.06 above Helix's figure, and the Qtc shown is the one that volume produces rather than the 0.70 they publish.

That is worth stating because it is not true of every Helix line. The IK datasheets quote their figure with a recommended DSP highpass applied and read several hertz optimistic against the raw sealed response; the IQ sheets carry no filter recommendation and their numbers reconcile with the anechoic math.
