Hi, Just picked up a HD130 head with 212RH speaker cabinet. While I have figured out what 130 and 212 means, I was wondering if someone could explain what the HD and RH means? Thanks, John.

HD has been discussed as meaning a lot of things but from what I remember from back in the day(I used to sell them new) it meant "Heavy Duty". The RH means reflex horn.

Thanks Mike. I've also got a 210-65 which does not specify HD, but I have seen models for sale that are identified as HD 210-50. It would be interesting to find out how the either the circuitry or construction differs. Thanks again. John.
