That would mean JBL should have used a 2225/2235 core to build an E130 or E140 and such wasn't the case. The 2235 cone kit in an E130 or E140 basket results in a hybrid with a tilted response, not as much area under the curve on the bottom end and more area under the curve on the top end. Retune the enclosure and change the passive or active filter accordingly.
I'd say poppin' E140, E145, or 2225/6H in a 4430 would be a major alteration converting them to something more appropriate for SR use, perhaps. 2235H's extended bass is an essential component of the 4430 design's sonic character.
You're correct, so don't use a more powerful magnet, such as an E130 or E140 magnet, and skew the balance of the driver.
