Efficient speakers -- What was your journey from A to B to ?

Very hard to make efficiancy speaker, no refrigerator size, First- lowbass driver must be active to mach sinsitvity other driver, Horn tweeter is must, dont look whizzer cone -is the chip mechanical tweeter attached to main cone and have the poor performance . Mid bass is very important , becouce most of Full range Drivers got luck it, If you close to NY NJ or been on CAF or NY Audio show probably you know brand Bacheaudio , also tal a look

I owned Avantgarde Uno’s  in 2002 & then upgrade to the Duo’s in 2004 ( or so). Their macro & micro dynamics were so much better than anything I had ever heard in anything close to their price ranges. They sounded excellent at any volume level & could easily fill a big room w/ rich full bodied, life like music. I then moved to another house & could never really get their powered subs to integrate just right. They always seemed a slight bit behind the big midrange horn. I think Avantgardes are now offered w/ their amplification & digital processing which is probably worth giving a listen to. 
 

I sold them & got into a very surround sound system w/ all Dynaudio Contour speakers & sub w/ Anthem electronics as I was watching a lot movies as well as listening to music but eventually I decided to return to high sensitivity speakers. I listed to all of the Klipsch models but settled on Volti Audio Rivals. They are a good balance of big, dynamic, “live sounding”, highly sensitive speakers in a “ reasonable “ sized, not crazy looking, simply but very nicely finished cabinet.

I have listened to the smaller Volti Razz which are also quite good & give you much of the Rivals sound in a substantially smaller & less expensive option. Both of these are worth either a trip to TN to visit Greg Roberts or the next show that Volti exhibits. I also know he is working on a new cartoon of his top of the line Vittoria speakers that will probably be amazing if they’re in your price range. 

@jonwolfpell Thanks for your experiences. It's helpful to hear how things change.

One would be surprised how little power the "supposedly inefficient" ear candy speakers actually use at deafness inducing spl levels.

I'm not ignorant of how affordable power is these days, and that it's good power, too. I have driven "supposedly inefficient" speakers to deafness inducing spl levels -- so I know that's possible, too. In other words, these are not new facts to me. What I am getting at -- which others here with efficient speakers also get -- is that there is a sonic experience with the combination of lower power plus higher efficiency which is different than higher/sufficient power + inefficient speakers. It's a nimbleness, a spry litheness -- in dynamics, pacing, but also in the way the tonalities are rendered. Perhaps you've not been able to notice it, yet. Once you do, you'll seek it as I am.

On that note -

Sometimes inefficient speakers need the volume turned up a little more to hear their full potential. Whereas more efficient speakers, and/or amplifiers well matched to the speaker, can be more effortless sounding, and at lower volume level fwtw.

For my home and setup, I spend 95% of the time listening at lower volume levels, so this kind of amp, speaker, impedance, and efficiency matching is a key objective.

Volti Rival

• for it’s high efficiency 100db to try out flea watt amps
• for it’s neutral linearity
