Point:
Just because a loudspeaker says 4 ohms on it's back panel does not mean it's actually 4 ohms..Perhaps it's 5 or 6 ohms or 2.5 ohms?? Or an 8 ohms loudspeaker is actually 6 ohms simply stating that 4 ohms is hard to drive is not the answer as the answer is all over the board. Speaker builders don't want to post 5 ohms in there stats they use 4 or 8 ohms.
Sony's new reference speaker is considered very hard to drive and it's rated at 4 ohms but my bet is that it's 3 ohms or less..again it depends on the Frequency as the ohm loads change by the frequency. 16 ohms loudspeaker? good luck... perhaps Avante-garde acoustic: several of there models are rated 16 ohms but they have there own problems such as sounding quacky and having poor bass... no simple answer here.
