hi guys


not really much of an expert in this field so just thought i'd ask to be sure --


i'm looking for an amplifier to power a jamo d7 7.2 system - I was looking at the Marantz 8002 ..


The issue is the speakers on the d7 are all at impedance of 4 ohms , I looked everywhere on the net and I couldn't find a rating for the Marantz at 4ohm..


Someone once told me that the power at 4ohm is roughly double that of the rating at 8 ohm.. So according to that a rating of 8 ohm x 125 for the Marantz would mean 250 at 4 ohm?


Is this correct ? Any problems that may arise as a result of using this amplifier with this speaker set? Someone told me that running amps at lower ohms than rated at might damage some component?


Thanks for any help !

I am pretty sure it will be fine. My SR7001 has no trouble driving my 5 4ohm speakers to reference levels

Marantz itself has given this a thumbs up...


Note that some 4 ohm nominal speakers can dip extremely low during use. Such speakers generally require an external amp to run properly, an amp designed for such abuse.
