4 ohm vs 8 ohm?

[pezza89]

Hi there fellow DIY audio enthusiasts! i have started to build up a collection of solid state amplifiers, and until now i have used one set of 8 ohm speakers which seem to be more than adequate - however i was wondering what the difference between 4 and 8 ohm speakers is? how does it impact sound? are 4 ohm speakers suitable for vintage solid state amps? Appreciate anyones help!

are 4 ohm speakers suitable for vintage solid state amps?

It will depend on the amp but most won't, especially cheaper ones.

Typically with SS amps distortion Approx doubles when you move from 8 ohms to 4 ohms. Also current requirements for a difficult load is increased.

thanks for the help guys! so based on all that...i have a jvc s-71 which has a massive transformer and caps (approx 90watts rms) im assuming it will be safe to use 4 ohm speakers however being vintage I was a little cautious...maybe i should 8 ohms would be safer?

maybe i should 8 ohms would be safer?

safer for sure, and likely sound better
