I was browsing ebay this morning and came across this pair of 604H with 612 cabs. Brand new from what the seller says. Anyways I am more interested in specs of these than actually buying them. I don't have an extra 7,500$ bucks right now

I didn't know they made any AlNiCo 604 with the mantaray horn. Isn't that horn a 7/8" throat? I checked my 604 reference site and indeed the 604H is the last AlNiCo 604. And it did come with the mantaray.

So is there a horn/driver mismatch on these, or is the horn a 1" throat?
