Someone mentioned that they thought the Carvin woofers were now made in China.
I just received a Carvin PS15-4 (15" non-neo) woofer and while it has no markings on it as to where it was manufactured, it does have Celestion sticker on it.
I checked the Celestion website and sure enough, on the 15" non-neo (green label) woofers the overall structure is identical.
I have no idea where the other drivers are made but the 15" non-neos are definitely Celestion.
