Efficient speakers with high powered ss amp?


Relative newbie here, so forgive me for the stupid question. I'm wondering if, in general, it's a mistake to mix 100 watt+ per channel amplifiers with efficient speakers. I know that low powered tube amps need efficient speakers, but do efficient speakers then necessarily perform better with less watts?

I'm looking for speakers that would be a good match for my Odyssey Khartago, and have always been under the impression that higher efficiency speakers are better than inefficient speakers. Would a 98db, 200 watt speaker be ok with the 110 watts per channel Khartago, or should I look for something less efficient.

Apologies, I tried using the search function to look this topic up, but didn't get any results, so I appreciate your thoughts and advice.

I have run 106db horns on 1000 watt SS gear it comes down to synergy sometimes it works well sometimes you may hear equipment noise. Or have a bit of hardness do to amplifier loudspeaker interactions but in general high power on hi eff is just fine.
If you had lets say $1000 to spend on an amp, a ten watt $1000 amp would likely sound better than a $1000 hundred watt amp. Other than that it's really a matter of synergy.
In general you do not need a lot of watts with more efficient speakers.

I have not heard any high efficiency speakers that I could afford or even want to yet that equals the best I have heard in general. For me, the key is find the right speakers that meet your tastes and integrate well into your room and then get the right amp to drive them properly. I would not worry too much about efficiency as a prime determining factor. Even the least efficient speakers out there today can be driven well by newer high efficiency amp designs like Class D/Icepower. The results if done right can be on par with the best I have heard out there.

The issue of the intention of the designer will play a huge role in this matter. In fact, if the amplifier technology does not match what the speaker designer had in mind, the crossover will not even work right!
I would also talk to Klaus at Odyssey to get his view as well;are you leaning toward a certain speaker right now or just starting to look?
