An 8R driver will measure about 5.5R ish for DC resistance. 8R is very much an arbitrary figure.
One pair of Hitachi mosfets can work OK with 4R but it much depends on the required power output. They are resistively quite lossy with about 1R Rds on and so best used in multiple parallel pairs... which is very expensive!
Probably the most reliable output devices used in audio though
