I have two of the 16 ohm woofers used in the 88-Special. I finally got around to measuring them using DATS. The following is an a average of the two samples, V(as) was measured using added mass method (31 grams) R(e) 9.35 F(s) 66Hz Q(ts) .45 Q(es) .48 Q(ms) 8 L(e) 1.65mH M(ms) 18.25g V(as) 22.5l SPL (@2.83V) 92.5
