How to unscrew driver from horn?

Hey guys, I am trying to unscrew a 1" driver from a horn in my garage but I guess the coldness in there has it frozen maybe. I don't want to tap the driver, is there any SAFE way to loosen it please?

Sorry but I am not sure what the "driver" is.
A tool, the part of the horn that makes noise,..... ?

As long as the horn is mounted solidly..... you can use a strap wrench to loosen it.
Don't hit it as you can crack the magnet.
Put a little bit of never seize on the threads once you get it off.

On higher end and pro audio equipment..... the driver screws into the horn.
Typically throat size is 1". Some go up to 2".

"The part that makes noise" is a pretty good definition of "driver."

Here it would be the cylindrical part.

The horn provides additional amplification of the sound.

Some folks call the driver the "speaker" or "loudspeaker" itself. The cabinet or enclosure particularly if it contained more than one driver and/or some electronics, would be called a "speaker system."

Thx, this is the driver:

https://www.parts-express.com/pedocs...spec-sheet.pdf

the Specs shows the Magnet Diameter as 4.5" so this strap wrench showing 8" should work?

Actually I brought the horn inside the house, let it sit for 2 hours to warm up and used a blow dryer and now it's out, thanks guys!
