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

After reading (and re-reading) all of "bache" posts, I think I understand what he's saying-   "High sensitivity loudspeakers roll off rather high in the bass department".

Forgive me but Isn't this captain obvious? Are there many folks that listen to high sensitivity speakers without a sub or two?

My mains (104db) start to drop like a stone at around 80Hz. 

Sure theres still some output at 40Hz. but its very light in the a#$. I use dual subs to fill in those bottom two octaves.It also helps smooth room modes..

So after going through the trouble to blend them into the system, I would never go back to 

+1 @larryi 

Your last paragraph sums it up to me…

Lack of dynamics (generally due to thermal compression) always brings me back to “HIGH SENSITIVITY LOUDSPEAKERS”

@blisshifi agreed…

Except aren’t we talking sensitivity?

so 90-94db= “medium sensitivity “ lolololol

I’ve tried some relatively high end speakers (in my world) with low sensitivity …

B741 SS……then floor to ceiling line arrays …then others I can’t remember them all.

While some had their attributes …(actually only the line arrays) none had the startling dynamics and realism of high my sensitivity horn speakers.

We all like different things. My freind (and neighbor) loved my low sensitivity speakers, he would comment on how “smooth” they sounded.

To me that’s code for “unexciting” lol 

@mijostyn that is interesting…it’s the polar opposite of my experience 

@mijostyn @charles1dad 

Absolutely!

Its why I said IME…

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…

Agreed @charles1dad 

@mijostyn These 8’ panels…where need they be located in relation to front and side walls? What size room approx?

The few Ive heard where mad far out into the room.…

@tannoy56 I only ask sincerely and not to disparage “bache”…

but how can you even make sense of what he said?

Because the speaker manufacturer displays frequency response graphs for each loudspeaker they sell.

i’ve also run sweeps myself, seeing the same response.

My experience this is not a particularly unique frequency response using high sensitivity loudspeakers. More common than not.

Most driver manufacturers measure sensitivity while mounted in an anechoic chamber running 1000Hz. 
That’s why it’s important to look at the entire F.R.
