Hi,

Can someone help me understand ohms. I have 4 ohm speakers and need to make sure I purchase the proper amp.



Thanks :)

Thanks. So if I have a MArantz receiver rated at 70w @ 8ohms, is it ok to drive celestion A1 speakers rated at 30w-100w @ 4ohms?

The 4 ohms is the impedance of the speaker - but it varies vs different frequencies. You treat it like a resistor - but the impedance can be as low as 2 ohms or lower at certain frequencies. This is a taxing load on some amplifiers (Pioneer I believe have problem with this)

It usually is not too much of a issue unless you drive the speakers very loud and then the transistor can overheat and shut the system down.

Marantz is a good company - you might write them about your question - and also your speaker company to find the real impedance low.
