Garbage In Garbage out

"Being successful in this industry takes great marketing."

Very true. Think about a company like McIntosh.

Do you for one second think they would still be relevant in the marketplace if they decided to ditch the glossy black faceplates and sexy blue meters?

And it's not just the audio industry, it holds true for every industry. 

@recklesskelly no thanks. That’s what caused the belly ache in the first place.

As for the whole high vs low sensitivity debate, the claim that speakers need to measure high in sensitivity is nonsense.  The whole argument falls apart pretty quickly in practice.  Take an 85db speaker and compare it to a 100db one.  A 15db difference would imply the high sensitivity speaker is 5x louder or in other words, uses 1/5 the power to equal the same volume.  My Dynaudio Heritage speakers just happen to be 85db efficient and I’ve played around with the Klipsch Heresy enough to know that it’s not 5x louder.  It’s not even a 2x or 3x.  It didn’t take much difference in dial to get them to even out.  And yes I realize an amps volume isn’t a linear increase in power but neither is the way we perceive sound.  I was also able to achieve sufficient listening volumes with a 50 watt tube amp so what’s the point of using high sensitivity speakers?  Go with whatever sounds best, there are always pros and cons.   The first speakers I ever owned were the Cerwin Vega AT12s, which measure 97db.  It didn’t take long for me to blow out the mids and tweeters in college.  I played them loud, developed a bunch of heat and melted the coils. A very expensive lesson in high efficiency speaker design was learned.  One thing I like about Dynaudio is they make bullet proof drivers.  I’ve had a pair of the original Contour 1.8s for over 20 years and not a single blown driver and I still frequently hit the mid to upper 90 DBs at my listening position, especially when watching movies.  I’ve plugged them in wrong, I even shorted an amp once with them plugged in, fried the amp but the speakers were fine.  I doubt too many 100+ db designs would last as long in my possession.  I might give the Heresy’s another go, the mark IV looks like a good update.

Train...ditch...wreck.

Hang on, another opinion extolling the virtues of powerful amps and inefficient speakers is right around the waveguide.
