Steve,
RE This is off topic but do you have TS data for the 2205H? (post #52)
First pic is a copy, with TS parameters, of a 2205 computer printout given to me in 1980 by JBL's Canadian distributor. I don't use the driver in the 5.5 CF box indicated since its too large for this older SR woofer (not intended for subwoofer use). This old one uses imperial measures.
Second pic is the TS for 2205H from JBL's own TS Table. That one gives Metric measures.
The main discrepancy between the two sets of TS is on Xmax when converted to the same units.
