What Do You Think . . . and How Does It Work?

(I love it...start a thread on PVC pipe, and I instantly get an ad for them. *LOL*)

Also happy that y'all have Finally gotten around to what I've been doing for the past few years....although mating a scaled down Walsh driver to a PVC pipe isn't easy to do either...

My only objection to the Pluto format is having the cone pointing 'up'.
If you flip it over...you've just created (mostly) your very own Ohm Walsh.
The radiation pattern has improved, and you're not depending on the ceiling anymore....to some degrees.

Now....grab the driver and stretch it and it's cone upwards a few inches.  That's a bit difficult to do, but I've gotten a handle on How.

Viola', a true Walsh driver as done by HHR and as done with the original Ohm F and A units.  Mine are scaled down, to reduce the amount of axial cone movement required by low frequencies.  I've chosen to focus on raidal radiation with that driver....

Mounted on a 6" Schd 40 pipe, one gets 'horny....as in the 'honk' the pipe creates.  Stuff it full of fibrefill, it goes away and one can always 'tune' the pipe by length vs. dia.  Alternately, seal it and play with 'acousitic suspension' (remember that?); works great for a bookshelf version....
...like the pair I'm listening to right now.

Hand the low frequencies off to a sub.
Active crossovers make that a snap.
Active room eq ditto.

OK....let's get rid of that tweeter.
How about a Walsh version.
Mount it above the main driver, aligning the voice coil centerlines and keeping it as close to the main as well.
Time alignment: check.
Phase distortion: gone.

Feed it streaming source, and avoid VTA, dust, scratches....any TT I use is a radial tracker anyway....

The only thing left to do is make Eric happy. ;)
I'll get around to that, soon enough.

Although Dr. L had said "Ignore the room."
(Yes, I've read his website....the Ohm patent...and more....)

Yeah, I'm having loads of fun, doing just that.... *VBS*

Regards, and Happy Memorial Day to the vets out there.
Y'all have and do make this all and more possible.
You deserve more than thanks; you deserve a VA that's worth your sacrifices...👍👏😃

kenjit,

I wasn’t suggesting paranoia, only the dangers of falling into it. As a fellow audiophile, you must know it goes with the territory.

Is the system power supply adequate? Is my amp powerful enough? Or good enough? Should I bi-wire? Do I need better cables? Spikes or isolation? What about Hi-Res?

With no doubt hundreds more silly questions to keep us awake at night. This hobby sure has a way of getting into your blood, doesn’t it?

Isn’t this also why we constantly remind ourselves to enjoy the music instead of listening to the equipment?

I don’t want to comment on other designs here but just to say that Linkwitz’s attention to the minutest detail is certainly impressive in my eyes.

As for your views on the Linkwitz Pluto’s, or mine for that matter, they’re both based on hearsay and initial impressions. Let’s just say somehow we have both arrived at different conclusions.

"The loudspeaker industry has taken us for a ride for long enough and now we must demand evidence.
We deserve it."

Correct. Totally with you on that. If the manufacturers have the evidence on performance, then it could and should be shared with any potential customer.

It’s already starting to happen with Harman products and as you can read on the Linkwitz site, there is almost a lifetime of shared information available there.

As evidenced in your many posts, however, you are not remotely qualified, to evaluate how well a speaker works, or does not work just by "looking at it". You don’t appear to have even the most rudimentary understanding from where I am sitting.  That may be harsh, but how else am I supposed to say it. There are any number of ways that audiokinesis could have addressed the issue, and buyers always have the option not to buy.

I have circumstancial evidence by looking at the picture of the audiokinesis speaker. I have no reason to believe there is some elaborate method hidden inside the box that mounts the driver differently than the usual way. I have also seen pictures of many other high end speakers that just screw their drivers in and call it a day. I have no reason to believe otherwise with this speaker.

The onus of proof is on the manufacturer. Im not the manufacturer.
We have been taken for a ride long enough. The time has come for the tables to turn. They have got away with unverified claims for too long.

Above, Kenjit is trying to bait me into defending my speaker. To anyone wondering why I don’t take up the challenge, let me point out that what Kenjit is doing is a classic behavior of a narcissist: Baiting people into defending themselves in an unwinnable argument.  Narcissists like to be on the offensive. 

Kenjit’s technique for turning every discussion into an argument and then winning that argument is to be contemptuous and dismissive of the other person and whatever information or evidence they present. When only his statements are valid and only his evidence is admissible, the outcome of the argument is a foregone conclusion.  

If anyone other than Kenjit is actually curious about the questions he raises, let me know and I will reply to you. Otherwise, imo this thread is about one of Siegfried Linkwitz’s designs, not one of mine.

They put a lot of effort into it, although ultimately seem to get something out of it useful only to themselves.
