These capsules are extremely linear and hardly need a calibration file for HT use if mounted properly (I use a straw of exact diameter).
Having tested several mics, I'd take the capsules over commercial mics using someone elses calibration file. The only way to do better is to get an individually calibrated mic...needed for serious speaker design...but not so much for HT.
