What is your take on high efficient speakers vs. low efficient speakers?


Consider both designs are done right and your other equipment is well matched with the speakers.  Do you have any preference when it comes to sound quality?  Is it matter of economic decision when it comes to price? - power amps can become very expensive when power goes up, on the other hand large,  efficient speakers are expensive as well.  Is your decision based on room size?  I'd love to hear from you on the subject.

Apogee duetta signature can be rebuilt to be higher sensitivity, with the newer bass foils and newer midrange/tweeters and better magnets can get them up to 96-98db.

The EV horns of mine both have a diffraction slot and sharp edges at the mouth area, and so may set the alarms ringing in many a horn-audiophiles’ head, but they actually sound very smooth after being properly implemented with mentioned DSP filter-actions above.

Good phrase - "alarms ringing" since that's what the sharp edges cause worry of - ringing. I get the impression from my listening that the ringing back to the throat is generally fast enough that it doesn't cause the kinds of issues that I thought - peaky, ear piercing response types of sounds, although perhaps it can if the horn is big enough. I've heard some of the really big diffraction horns bothered people in the past but it could be they just weren't well equalized. So I think I agree with you that properly equalized diffraction throat horns can still sound quite smooth and natural, although some imaging and detail might be obscured. The better high frequency dispersion may be more than worth it in many scenarios. 

I always thought it was slots or discontinuities in the THROAT of a horn that could often cause a “spitty” or sibilant sound compared to an identical horn with a smooth throat…
