The constants of the baffle may be measured after the loudspeaker constants are known. Refer to Fig. 7.6. The quantities
R
_{
AR
} and X
_{
AR
} are determined from Eqs. (7.31) and (7.32). The electrical and mechanical quantities are measured directly.

Using the same procedure as for measuring f
_{
S
} and Q
_{
EC
} in Section 6.10, determine a new f
_{
C
} and Q
_{
EC
} and solve for C
_{
AB
} from Eq. (6.71) so that

${C}_{AB}=\frac{{V}_{AS}}{{\rho}_{\text{0}}{c}^{2}\left(\frac{{f}_{C}{Q}_{EC}}{{f}_{S}{Q}_{ES}}-1\right)}$
