| I don't know. I looked at the Carvin's thiele-small parameters, which are probably old and out-dated, but the xmax is 2.35mm on the neos and 4mm with the PS10's. I have a-b the BR210 (sealed cab) and the Brx10.2 neo (ported cab) and if you play mostly 4 strings, the BR210 is great. Tight, punchy, articulate. If your more of a five or 6 string player, its the BRX10.2 hands down. Just my experience.
