4 ohm speakers to use on 8 ohm reciever

[Alamat]

I have these 4 ohm Klipsch speakers that I's like to use with an old Denon 8 ohm receiver. Aside from doing a series on it ( ...right? ), is there a way I can stick a resistor or something on it so they don't blow up the Denon?

i've always been a bit fuzzy on speaker resistance, but i think it should be ok to use the 4 ohm speakers as long as you don't turn them up too high.
the receivers are rated at a resistance for a certain amount of power, as long as your denon isn't super cheap, it might be able to handle 4 ohms without overheating or something?

Actually as speakers go - they don't really sit at "exactly 4 ohms". At different frequencies the speaker has different impedences. They'll go down below 2 ohms and up past 100 ohms. Generally speaking it just means that the 8 ohm speakers are more purely resistive (and have more wire) than the 4 ohm speakers. It's not good, nor bad, just how the thing is built.

Just keep it under 7 (out of 10) and nothing horrific will happen.

Your receiver probably has overcurrent protection. Don't turn them up too loud and you'll be OK.

What receiver is it exactly? Some "8 ohm" receivers can drive 4 ohm speakers without any issues, usually the older better built ones. I know the last generation HK AVRs can handle 4 ohm speakers without issue even though they are sold mainly as 8 ohm receivers.

Ive driven 4ohm speakers on my systems and managed not to kill them. And the systems have been ok. Occasionally the internal (speakers and systems) circuitry would kick in and either the speakers would turn off or the system would shut down the volume. Of course all of my amps and receivers are over 8 years old at the very least so I dont know what todays systems would do but I dont think much has changed in years.

What klipsch speakers are they?

From what I read some of the older models were labeled 4 ohm when they were actually 8 ohm. It was purely a marketing ploy.

I ask because I have run 4 ohm Bass shakers off of a Kenwood receiver which is 8 ohm which was my dad's. A year later, I heard the receiver had died. 'Course I didn't tell him that....I like having balls.
I will try ur suggestions. On another note, I also have the Logitech Z5500 and looked up the specs, 8 ohm. I have 4 of those Promedia Klipsch sitting around as well which I know are 4 ohm and I am pretty sure they would sound a whole lot better than these Logitech ones. U guys think that's a good idea?

It was going to die anyway.

Any recent receiver is going to have overload protection. My old 5.1 JVC with just DD/DTS will go into protection mode with I turn up the 4ohm bass shakers too high.
