Always check

Bought some x12' a long while ago. PAudio 12mb and comps. Changed the comps for BMS, just popped the horn out, lovely.
Builder of cabs hadn't recessed the bar handles, so I popped them out last week, ready for some routing. Funny I thought, black wire to red. Checked other cab, same.
They had been out of phase for the last two years!

Was the whole cab out of phase or just the comps. If just the comps you wouldn't really have noticed.

Some manufacturers send the drivers out to be reverse wiring. JBL does it and I think some of the Eminence HF drivers are the same as well.

Na, just the DRIVERS out of phase.

JBL correct, Emmi are normal IIRC
