Don’t tease him.
I see it coming.
Another L.A. article from Scott Wurcer

Not on this one. Reading between the lines there are folks that want their wall shaking ear splitting bass. I confess I have not listened to any recent JBL speakers but in the past they made everything sound like rock, feh.

I don’t say it in public but I have different DSP settings for rock and for classical music with my loudspeakers

Yeah, wasn't there back in the day an "east coast" and a "west coast" sound, of which JBL found membership in the latter?

< gasp > George! 😱
If you can't go from Stravinsky to The Doors without pushing any buttons, you're not dialed in yet. 😀

You are right. (Sisyphus was destined to roll a boulder, me to adjust the knobs)

UK and Japanese completed the set. I'm sure things have changed since then (maybe).

Why aren't you mining the file's metadata to determine which DSP settings you need?! 😉

Daniel I do it by ear but which file are you referring to? (and what is a file's metadata?)
George
George
So my post was tongue in cheek first off, but (for audio at least) metadata is textual data that is included in the music file's package that tells you the artist, song title, track number, album, etc., etc.. One of the categories is genre, so it wouldn't be too hard to have the computer read this text data and load the appropriate DSP filter coefficients. (I'm thinking from a linux script perspective at least)
Ah, so.
Good, thanks for the suggested scenario.
( I can tell you and Jim that with the same settings I can play Stravinsky and Frank Zappa but Doors, no)

I just made a "Lifetime Buy" of BF862 JFETs @ Arrow ; Mouser & DigiKey have none
It appears the supply is gradually drying up; zero in stock and zero on order at Mouser. Zero in stock and "Last Time Buy" status at DigiKey.
Arrow in the US has stock, so I bought 500 pieces while I still can. Recommend others do the same. Arrow's price was quite good; use Octopart.com to do a comparison against other sellers, domestic and overseas. Free shipping to California but sales tax was charged.

Thanks, Mark, I need to order some stuff from Arrow so I'll throw in a few (100) in my next batch.
George, your secret is safe with me. 🙂

Sadly based on current project throughput, a lifetime buy was only 50 pcs for me.
Put me down for 2.

WoW. that is really good. -60-80.
-----------------------
A lot (most all) driver tests are in near field and thus high spl can be easily measured when up close and personal.
105dB is easy to get... easier on PRO type speakers. No one would assume that at a listening distance that the spl would be that high.
I had been on a quest to find out why all sound was compressed compared to live sound. I believed it was done at the studio. I found that assumption was not true with the M2. It was the drivers used in most speaker systems. The same CD recordings had significantly, measurably greater acoustic output for peaks like I never saw or heard before. Much less compression and greater dynamic range from the M2. JBL touts this in their lit as well. And, should not be over looked as a problem for accurate or realistic reproduction.

You show ~.3% you need to take that up with Earl.
It seems I did and I assume you might have read the result 😉
There are some who just keep on saying you cant hear this or that... and are ready to jump on the band wagon of anyone who agrees with their bias.
News flash...... a highly recommended SMPS at DIYAudio was just tried to power Damir's amp - one channel. The amp was both noisier and distortion was higher by 10-12 times.

No wonder. And I assume that peak output power capability with the SMPS was reduced as well.
