I tried to check that Atlanta ad before I posted my alert, but by then it had been deleted. Sorry for the false alarm.

Snake your zip cord through a section of garden hose. Nobody will ever be the wiser.

I remember that. "2 + 2 = 5, for sufficiently large values of 2".

"Magic" is the only accurate description of that dimension, as in "magical thinking".

@Dave A, research by Medwin indicates that the perfect length is actually 57 1/8th inches. Whom to believe? Taking the myth slightly off-topic, as an engineer who specializes in DSP, I'm just waiting for somebody to claim that they can hear differences in the CPUs used to perform the arithmetic.* *There are some architectural differences that could potentially affect the audio; fixed-point vs. floating-point, 32-bit vs 64-bit, etc. But any two processors that implement the same arithmetic in the same format will produce the same results. If they don't, then at least one of them is broken.

Klipsch Palladium P38 speakers with matching P312 sub in Merlot finish. https://stlouis.craigslist.org/ele/d/edwardsville-klipsch-palladium-speakers/7547081058.html Unfortunately, only photos of the boxes in the ad. No affiliation.

That's a lot of very long-term employees. Must be doing something right. Also, striking difference between "Arkansas accent" and "Missouri accent". You'd never know that we're neighbors.

Yes, I've done plenty of assembly language programming. I actually like it -- the programmer has complete control over everything. It's even worse than that. At least C/C++ are compiled. The language of the day seems to be Python, which is interpreted, and takes about 10x as long to run as compiled C to do the same thing. But processing power is so great that few people care, or even notice.

In 1993 I developed a signal processing technique that is so computationally-intensive that I thought I would never see it run in real-time during my lifetime. By about 2010 it could run in real-time on a telephone. It's an amazing time to be an engineer.

Well, you can Zobel an impedance peak https://community.klipsch.com/index.php?/topic/187697-measurement-systems/&do=findComment&comment=2436802. As for the rest, I can usually model horn response and driver response, and compensate for them, in DSP, unless they're really unusual.

The pitfalls of keeping a low profile.

Again, I don't want to name any names, but at least a few of them have tried to participate in various audio forums and been thrown-off of them, either for blatant commercial self-promotion or for rudeness to other members.

@ClaudeJ1, you and I have had the privilege of rubbing elbows with some heavy-hitters in this (and other) industries. Some of them, like Roy, are down-to-earth country boys who will take you fishin' in the morning and then dig deep into the tech in the afternoon. Others, who shall remain nameless, can be real prima donnas who will berate you for asking the time of day. I guess it's the same everywhere.

Free advertising. He's retired and living in picturesque Bloomington, Indiana. He's almost 82, now, so slowing-down a bit. Don's Website I think that the world has finally figured out that horns don't have to sound like "horns" if they're designed properly. Modern computational power and finite element analysis have made that possible. 3D printing has made prototyping much easier.

I corresponded with Don as recently as last December, then he suddenly stopped responding. I don't know whether there is a health problem, or some other pressing matter.

Yes, I'm familiar with that paper by Don Keele. (And with Don Keele himself. I worked with Don at Electro-Voice, and got along with him just great. That's part of the reason that I wonder if PWK and I would have gotten along -- I think that we would have either "clicked" or hated each other's guts.)

It's been quite a lot longer than that. Yesterday I was reviewing a forum conversation that I had with him back in 2008, when he was known as "Bodcaw Boy."

I've met @Chief bonehead, and he's a regular guy, just like me. On second thought, maybe that's not the best example ...

For innovation, the math can either lead the design, or the design can lead the math. In the former, one can look at all of the equations and notice that setting constraints and variable values in certain ways leads to interesting outcomes, some of which may be useful. In the latter, one has the idea for the interesting outcome first, and then tries to manipulate the math to achieve that outcome. I suspect that Roy's "modified tractrix" followed the latter procedure, and I would find it interesting to see how that happened.
