Speaker sensitivity vs SQ


My first thread at AG.

Millercarbon continues to bleat on about the benefits of high sensitivity speakers in not requiring big amplifier watts.
After all, it's true big amplifiers cost big money.  If there were no other factors, he would of course be quite right.

So there must be other factors.  Why don't all speaker manufacturers build exclusively high sensitivity speakers?
In a simple world it ought to be a no-brainer for them to maximise their sales revenue by appealing to a wider market.

But many don't.  And in their specs most are prepared to over-estimate the sensitivity of their speakers, by up to 3-4dB in many cases, in order to encourage purchasers.  Why do they do it?

There must be a problem.  The one that comes to mind is sound quality.  It may be that high sensitivity speakers have inherently poorer sound quality than low sensitivity speakers.  It may be they are more difficult to engineer for high SQ.  There may be aspects of SQ they don't do well.

So what is it please?

reread my post, i said zip about anything but absorption. take another run at finding a 6” absorber in nature. Its a hole in the acoustic space the brain is trying to reconstruct. I am a principal in a recording studio with a mobile location rack. You can catch up later.
the natural world is full of diffraction, most sterile audiophile rooms lack it bigtime...except for the forest of amplifiers blocking the path to the turntable ( which should be off to the side )
The GR Research high sensitivity speakers are, in a word, stunning.  I had a pair of the old Super V's.  Then a pair of Wedgies on top of 2x12 open baffle servo subs (flat to 20Hz at brutal levels).  I'm getting ready to build a pair of NX-Tremes.  Once one goes to really good open baffle speakers it is very, VERY hard to consider anything else.  Watch these:

i spent a decent amount of my career in anechoic chambers testing advanced technology, simple stuff , some suborbital. my prefered vendor of loudspeakers ( since 1977 ) actually have and use a chamber for development and importantly production, doing the precise work of tuning to a standard and nulling. Do you have a chamber ?
