speaker impedance

If upgrading speaker. Typically you want to find speakers that captivate you… ignoring requirements. Speakers are very important to your enjoyment and if they don’t captivate you it is unlikely any amount of changes in electronics is going to help that.

While typically 8 ohm speakers are “easier to drive” but there are so many variables… I wouldn’t let it drive your choice.

If you chose planar speakers (electrostatic or ribbon), they require a lot of power (current). Then you will have reason to pause and consider what other changes you may have to do.

Best find speakers that sound great to you… then see if your electronics are up to them.

They are about the same wiht any modern solid state amp.

I mean, in an ideal world, higher is better = low current and easier to drive, but from a practical perspective, impedance only matters a lot with tube amps or speakers that dip below 4 Ohms.

The only thing really important is their SQ. In a few cases you might find a better amp to drive them. 

Buy good speakers designed well and the designer will decide which impedance works best.

Are there any high impedance speakers out there designed with tube amps in mind? I see you can get 16 ohm compression drivers. A couple of 8 ohm woofers could be wired in series to give 16 ohm impedance. Doesn't seem to be a popular design choice.
