I chose 87dB sensitivity as the thresh-hold, just to narrow down a lot of options...

Using MZKM spreadsheet:
https://sites.google.com/view/speaker-headphone-data/speakers/speaker-selector

Rating of 3 = Amir recommended = relaxed/lounging panther
Rating of 4 = Amir's highly recommended = golfing/soccer panther

Hope that helps.

Also, you didn't specify any budget?

dB per metre or 4 feet? :)

I get the impression that audiophiles don't like high-efficiency speakers. Are they too accustomed to the lower efficiency ones?

High sensitivity speakers play well through low wattage amplifiers . And the low wattage amplifier costs much lesser .

WANT TO KNOW THE TRUE SOUND QUALITY ABOUT OMEGA & KLIPSCH
SPEAKERS WHICH ARE OF HIGH SENSITIVITY .
Don't know much about Omega, but I would avoid Klipsch.

Amir's review of R-41M:

No chance to fix with EQ, avoid.

Amir's review of RP-600M:
https://www.audiosciencereview.com/...sch-rp-600m-speaker-review.12138/#post-354117
These are salvageable with EQ....but I wouldn't buy anyway.

Also, read this post to understand sensitivity advertised vs measured:

@Sancus beat me to it ;)

That may well be the case, but I think that the compromises that have to be made to get high sensitivity also result in worse performance.

1) High sensitivity requires lightweight cones which are more difficult to make rigid, so have a worse breakup behaviour resulting in coloration. This can be mitigated somewhat by using exotic i.e. expensive materials, and/or stronger magnets, which in themselves cause other issues.

2) Horn loading is another way of achieving high sensitivity, but unless the horn is very large, bass will be limited, and any folding results in coloration.

3) Crossovers tend to be simple, as complex crossovers don't help sensitivity, and consequently slopes are low and out of band attenuation less than ideal, especially when using a lightweight paper cone as in 1) above.

4) Removing the need for high sensitivity allows more scope in design, given that high power is cheap and clean, although the problem of heat, compression and longevity/reliability becomes more serious when a loudspeaker is required to take more power.

With active 'speakers and Class D amplification, there's little incentive for high sensitivity, so more emphasis can be placed on accuracy.

But class d amplifier is neither as good as class AB nor class A .
And high wattage class AB costs much higher which in case of class A , increases manifold.
