I don't think so, I think this particular model goes down to 6 ohms. But they have much better models that do handle 4 ohms. Click the bottom link and you'll have to check.

Mostly likely yes. 4ohm speakers can demand more from an amp or receiver at high volumes, but in most cases you will never know the difference. I have had 4ohm speakers paired with a 75watts/channel Onkyo receiver in the past, and it was never an issue. Even if a receiver doesn't post specific 4ohm ratings, that doesn't mean you can't use with 4ohm speakers.

While one can use 4ohm speakers on a 6ohm-rated receiver, I don't recommend it, especially at high volumes. This can cause damage to the components on the receiver's main board, which has provided me a career in the audio repair industry lol. Using inappropriate speakers can damage MOSFETs, resistors, and various smd components, which are much more labor intensive to replace than just a blown fuse. I fix these for a living, trust me on this Smilie Really fun job, tbh.

Trust me, I used a the set-up I described for 30 years without an issue, including many parties, which by definition are not low volume. If you have been in the business very long, you know that a 6ohm spec is just the company trying to make their specs look better, and not a statement of limitation. That is the reason the FTC developed the standard power measurement back in the '70's, which is for 8ohms. Even if a receiver or amp doesn't have a 4ohm spec listed doesn't mean it can't handle it, some companies just don't bother to post it. When you stated "high volumes" you left a word out. It's "excessively high volumes" if it's causing the damage you describe, which can happen even with 8ohm speakers if the volume is high enough.

"Excessively" high is true. You can use a 4 ohm speaker even if a receiver says 6 ohm, but I see damage from this very frequently at work. I literally repair these for a living, but it's often from customers using inappropriate speakers or using them incorrectly.
