A Broad Discussion of Speakers with Major Audio Luminaries

I would like to mention one minor detail: on page 119 of the slides, the spinorama shown is for a 3-way floor-standing speaker (not 4-way); As it is my dream speaker, I am very familiar with its specific spinorama profile and recognized the model immediately :)

Wow, there is no identification of the speaker on that slide and you managed to recognize it!

Actually, I recognize it too. It's a KEF Blade 2. It is recognizable by the irregularity in directivity at 200Hz, which is where the front drivers transition to the side drivers. I don't know if it's sad or hilarious that we can both recognize a speaker from its Spinorama alone, maybe you and I need to get out more.

It is truly a fine art to recognize a speaker based on the spinorama data alone :))
So its ok in my book ...i guess :D
Also, I am taking my wife on a summer holiday
Starting tomorrow, I will be away from the audio gear, forums and reviews for one week :)

OOPS! A typo, because I certainly know better. I think I know how it happened, but that is no excuse. Thanks for noticing - it has been corrected.

But I don't think there has been a failure to communicate!
 
If I might be so bold, your book assumes a certain level of technical competence and knowledge on the part of the reader. Hobbyists don't know what an Energy-Time Curve is. Hardly anybody outside of ASR knows what we mean by "minimum-phase", and I would wager a large number of people here don't know either.

If our goal is to expand scientific thinking amongst audiophiles, it has to be clear that acquiring such knowledge will benefit them.

Some journals we've published in encourage the inclusion of a breakout box explaining technical terms used in the paper. This is a good option (as long as the explanations are written to be comprehensible to the nonspecialist reader!)

For a digital text to be read in a web browser, it is easy to add mouseover/pop-up explainers for any word.

For e-books, not so much, though Kindle does have a general 'dictionary' lookup for highlighted words.

Aye, and that's the rub. I have used text boxes a few times in my books, but in the end they take space that is necessary for telling the prime story. Something is sacrificed in print books with a limited page count. Even color was not possible in mine. It is very constraining. And then there is the question: how simplistic does the breakout box content need to be? At what intellectual level should the explanation begin? I consumed multiple chapters just to explain what a frequency response curve means - start with dB, loudness, pitch/frequency, the meaning of irregularities, tilts, and so on. In fact, I wrote much of an entire book explaining it. Writing an explanatory text while defining all terms used within it is an encyclopedic endeavour if one is thorough, and it does not, in my opinion, qualify as "For Dummies".

That is why I put some effort into the website accompanying the 4th edition, especially the PowerPoint slide shows that, I think, explain much of the book content in a more digestible format. But even these slide shows have been considered too complex for much of the ASR audience, and simplified "For Dummies" versions suggested.

I have spent decades presenting and discussing this content to audiences ranging from CEDIA members (many are audiophiles) to engineers, and general university students, and listening to the feedback and questions. ASR and other forum discussions have added another perspective which includes input from people of many very different backgrounds. Misunderstandings are frequent, even among people with technical backgrounds.

It seems to me that much more simplification in the "For Dummies" direction, simply will create "Dummies" who think they understand a subject that they really don't. This simply adds "noise" to the discussion.

Amir and Erin measure, present and discuss spinoramas and more - definitive data - in print and video forms. Their opinions have substance. The problem is that they cannot review all products on the market, but spinorama data is available now from other sources. If average audio enthusiasts want to competently interpret those data they will need to do some serious homework. Otherwise, we end up with misleading, seemingly simple, "room curves" as unreliable guides. Loudspeakers are not that simple, and bass problems in the listening room are not even considered - two chapters in my book, and about 30% of one's overall assessment of sound quality.

It is complicated . . .
