Is that radiator fins a patent of JBL? AFAIK, no other SP makers employed thatTRICK. If it is worth introducing for controling dispersion, why others do not follow JBL?
Actually several other speaker manufactures used them. It was quite fashionable by JBL's competitors in the late 70's and early 80's. to provide the JBL "look", even if it didn't necessarily help that particular speakers sound.
I listened to the recent model (exact model NO. is missing) didn't have fins and didn't sound harsh. That model I listened to at a big electric store wasn't a studio monitor, probably. Yet, it employed 38cm/dia woofer, and was for home use, three way. I don't know WE much as a speaker maker, but WEST LAKE never did do that, I believe.

The acoustic lens was primarily used on horns with a fairly narrow disbursement to widen it. Nothing more, nothing less. If the system you listened to used horns it already had adequate dispersion. The horns used by Westlake, for example do not, and that's why they don't use them. Hope this as well as the links provided help.
