receiver for 4 ohm speakers (1 Viewer)

[AndrewKra]

i have 4 ohm speakers and i need to get a receiver with at least 2 optical inputs and 1 coaxial for around 200-275 dollars. i found a receiver that i like as mentioned in my previos post, but it is an 8 ohm receiver. the receiver that the speakers were meant for put out 6 ohms and the receiver that im looking at has an option for you to switch to 6 ohms. would that work alright?

Andrew, you ask this sort of question here in the Receivers/Amps area, not in Basics (which is for general discussion at the beginner level). As to your question, "ohms" are a basic measurement of resistance, and they relate to speaker systems. Any amplifier that is competently designed can drive any speaker; how much power it puts out is largely determined by the resistance of the speaker (as stated, in ohms) — although a very few amplifiers (notably, McIntosh's designs) put out the same amount of power at most resistance levels. And the lower the ohm factor, the greater the power output of the amplifier.
