An ohm question...

[Early B.]

All things being equal on two separate systems, except the speakers on System A are 4 ohms and on System B those same speakers are 8 ohms. Since more power is being used to drive the 4 ohm speakers, will the 4 ohm speakers sound a bit differently, i.e., more impactful, dynamic, robust, etc.???

Thanks.

How can the exact same speaker be rated at 4 and 8 oms? You'd have to change something in the speaker to make it 4 ohms therefore you've altered speaker set B so it may sound different. Not because the actual change in ohms but whatever you used to change it from 8 ohms to 4 ohms.

Many drivers can be purchased in 4 ohm or 8 ohm versions. I dunno if crossover changes are needed, but my question is really about the power differences.

If exactly what you described could be achieved, you should only have a gain of 3db from the doubling of power from the amp.

Both speakers have the same efficiency rating, so it would take the same amount of power to reach XdB/w/m. But speaker B would have an amp with twice the amount of power remaining. Is that why speaker B would have a gain of 3dB? I'm just looking for clarification.
