Beranek's Law
It has been remarked that if one selects his own components, builds his own enclosure, and is convinced he has made a wise choice of design, then his own loudspeaker sounds better to him than does anyone else's loudspeaker. In this case, the frequency response of the loudspeaker seems to play only a minor part in forming a person's opinion.
L.L. Beranek, Acoustics (McGraw-Hill, New York, 1954), p.208. (RIP 2016 @ 102 Years Old).
Follow Ups:
In the NASA / acoustic levitation days my old Boss Roy Whymark was a friend of Leo's and had worked with him.
When Roy passed away, inherited some of Roy's books including this one.
Don Davis had said once "we stand on the shoulders of giants",
Leo B being one of them.
Yes indeed, Tom.I had the privilege of helping in the development of the best color sensor, the Foveon X3, I have books by Carver Mead (the guy who coined Moore's Law, and co-wrote the book on VLSI), both signed by him, as well as his former Chief Engineer, Richard F. Lyon (inventor of the Optical Mouse and the Google Street Camera). He signed my copy of his book "Human and Machine Hearing," a total geekfest in the science of Sound Wave Detection.
Giants indeed! Some are still with us breathing!
Leo Beranek lived to be 102, my Dad's Mom lived to be 104, so I hope I got some of those genes!

Indeed he was. I learned a lot from that 1954 book, when I first started working in acoustics. I have two reprints of it, paperback and hardcover.
I attended an Acoustical Society of America conference in Boston several decades ago, and Beranek led a tour of Boston Symphony Hall, with which he was closely connected. One of my most treasured experiences.
Very cool experience!
Sad there isn't a video of so many things that are only distant memories.
We should make that video.
I fear it would be a very small audience with no ad support, however!
You have Beranek's "Acoustics"?! That is another classic text. I wish I had it.
These days, though, it would be more just for reading rather than being useful, since I'm basically retired. I do have his "Music, Acoustics & Architecture", which is another landmark work.
A few other classics in my "library": Harry Olson's "Acoustical Engineering" and "Music, Physics and Engineering", Knudsen & Harris's "Acoustical Designing in Architecture", and Tremaine's "Audio Cyclopedia". All excellent sources to have!
But I don't have Beranek's "Acoustics". :(

All you need now is Kolbrek and Dunker's "Horn Louspeakers" book History Design and Theoryhttps://audioxpress.com/article/book-review-exploring-high-quality-horn-loudspeaker-systems

I have Olson's M.P.& E. and tons of more modern PDF's and Two AES books on Loudspeakers, which include the works of Thiele and Small.
They all overlap in their useful data, and pretty much agree.
I also have D'Appolito's book on measurements.
All good stuff. However with Hornresp and REW, it's much easier to DO, and listen to the results rather than Read!
I have the 1940 and 1957 versions by Olson. Other than T/S specs there's not much in them that isn't still current.
Mine is 1957.
Yup, he certainly understood physics and the associated math. It must have been a major chore to produce that work back then!

Here's one from 1940. It is an amazing piece of work.

Yes, that is what Olson published, and then later updated to "Acoustical Engineering".

Sort of like Percy Wilson's Zanzibar Fallacy which implies that for most audiophiles their reference is their own system.
As opposed to Paul W. Klipsch, whose reference was a live Symphony.He recorded hundreds of perfomances on his own reel to reel tapes using only Two spaced Omni Microphones for stereo on a 2PH3 channel playback system.
I had the same reference system as he did for 30 years, until I discovered Home Theater with more channels than 3.
