But it wasn't much of a thread to start with.
Compared to what?
Besides, you never thanked me for honoring your request by posting PWK's measurement of the Bose 901 as a great example of IM distortion.
You stated that the $30,000 'Philharmoia by Jean Nouvel' speakers in your improperly posted link were almost as bad as the Bose 901.
I asked for some proof of that.
We all know the Bose 901 story.
You replied to the thread that had the Bose 901 IN THE TITLE and didn't specify otherwise, so I assumed you were talking about that.
Specific communication without assumptions is a wonderful thing.
I don't know "we all" but IM distortion of the bose 901 is just one example.
As to an 8" woofer, which appears to be both popular and overpriced, maybe people are not sensitive to that type of distortion, which transcends any brand.
AM being worse than FM because of the side bands.
But hey, "we all" already know everything so I'm done wasting my time here. You can all go off and spend 30-50 grand on 4" "woofers" for all I care at this point.
Have a great life.
If you take the time to READ the subject line of my post, it should be obvious that what is missing is evidence that the speakers you originally posted about indeed produce "IM distortion almost as bad as the orginal Bose 901".
Maybe they do.
It's all speculation on your part unless I'm missing something and you've somehow optained measurements of obscure speakers being offered for sale on the internet.
I've never been much of a 'cones and domes' guy myself, having owned horns in one form or another the last 20 or so years. But I don't spend my life screaming and yelling about the prices of audio gear I have no intention of ever owning.
Wouldn't leave much time for anything else.
Aside from a mild miscommunication on our parts about subject titles, I see no real conflict here.
And no, I did not "scream and yell" as you put it. My keyboard did not have the Caps Lock on, so in the case of internet etiquette, that clearly was not the case, except for a few key words.
Paul Klipsch has also measured what an 8" driver does with intermodulated frequencies. Using the same driver, he did both direct and horn loaded measurements. When I asked him about that he flipped the pages to the collection of his papers on his desk to point out that horn loading that driver produced an extra 15 db of output with about 25 db less IM distortion, which he said made it "approximately proportional." Which was really 10 db better than predicted.
I don't know who you are, or what you do, but now that you said you have been a "horn guy" for 20 years (40 for me) it bears another question:
If you are truly living the dream with an all horn system, as I'm guessing you are, why do you bother with so much time and attention to simple opinion on my part about overpriced IM Distortion Generators?
No matter how fancy the magnet, voice coil specs, diaphragm material, shorting ring, suspension, etc. an 8" driver is made of, the IM distortion can only be as good worse than the best of physics can predict (Beers and Belar), never better.
To further make my point, I have NEVER gotten a straight answer from any engineer or representative from a speaker company about IM distortion of their speakers. Rhetorical question alert: I wonder why?
but not my religious faith. 300B amps like high efficiency and JBL 2441's with tractrix horns do that fine.
But then I view speakers as a matter of picking ones favorite compromises. I've heard decent to very good sound from just about every configuration out there from single driver, open baffles, monkey coffins, to large panels.
There are a lot of things that I don't care for in 'high end' audio, but I generally resist the temptation of starting threads just to address them.
Maybe I should rethink that. ;-)
Ah, I see. Thank you for the upgraded clarification.
Horns are my personal preference also, and not a Religion.
There are other things that can sound good when done right. All their different anomalies and positive nuances. All are a compromise of some sort. But it's a fun hobby experiencing them all through temporary or permanent ownership whether they are commercially produced or home built.
I've been building my own speakers and systems since I was 12 years old and I have a technical background. Audio is just a hobby because I really like listening to music in a darkened room with eyes closed, which is a much more enjoyable for of "double blind listening" as opposed to ABX box testing, although I have done that too, since I was an AES member and attended the meeting where the guys who designed the ABX box were demonstrating it.
I'm still amazed at how many great software tools we have available today for for free or very little money to explore endless possibilities without having to make sawdust like I used to do (and still do without as much waste as before).
But no matter how great of a simulation we perform, it's the EARS, the ROOM, and the program material that give us the joy of perceived success. What a Grand Illusion Audio is!!
