You could run a 160 ohm driver on a "regular" amp and it wouldnt hurt it. The higher the impedance, the lower the "draw" on the amp. So yes, you can. But remember, you will only get about half the power into a 16 ohm speaker as you would an 8 ohm.

Intergrated amps that Double down into 4 ohms?

WebHere's an example. Suppose the impedance of your speaker is 4 ohms, and its Continuous Power Handling is 100 W. If you are playing light dance music, the amplifier's 4-ohm power should be 1.6 x 100 W or 160 W continuous per channel. To handle heavy metal/grunge, the amplifier's 4-ohm power should be 2.5 x 100 W or 250 W continuous per channel. WebSearch. Can I use 4 ohm speakers with my AVR or power amp? Yes, you can. To understand this a bit better, first realize that all amplifiers are designed to deliver a signal into an electrical "load" or resistance presented by the loudspeaker. We measure resistance in units called "ohms" (after the German physicist Georg Simon Ohm, 1787–1854). def of parameter
