When he starts referring to himself in the third person you know you've got trouble.
What Do You Think . . . and How Does It Work?
While watching vids on YouTube, I came across this pipe speaker design from a Dr. Linkwitz (see below). The sound of this speaker is said to be impressive. I was wondering if you know about this, how it works and what you think of this speaker design. Also, what do you think would be the best room placement for such a speaker, and would you be tempted to build them?

Like many of us here you also seem to be searching for definitive answers and ultimate truths when it comes to loudspeaker performance. Unfortunately, there may not be any. Some one searching for answers and truths wouldn't constantly reinvent themselves and his/her position on subject matters. The word "integrity" means being the same throughout, being consistent as opposed to convenient. |
Quit while you are behind. One Linkwitz mainly discusses stamped baskets which are low cost. Two he says that if there is a resonance it must be dealt with. There are many ways to deal with resonances. Do you have proof this speaker has not dealt with them. It's painfully obvious you don't understand speaker design.

One Linkwitz mainly discusses stamped baskets which are low cost. Two he says that if there is a resonance it must be dealt with. There are many ways to deal with resonances. Do you have proof this speaker has not dealt with them. 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. Linkwitz says :
Why would linkwitz bother to mention this if it applies to stamped frames only? Most drivers are not stamped. Most high end manufacturers do not address these types of issues. The question for Audiokinesis is can he show us that the way he mounts his drivers is in fact the best way acoustically and that it wasnt just screwed in to save money and time and that the difference wasnt deemed unimportant? Did he do blind tests using one version with drivers screwed in and the other with drivers mounted differently? Or is he just making assumptions? What evidence is there that the audiokinesis is a better speaker within the marketplace which is full of similar boxes with drivers in 'em? You would expect better performance for that kind of money no? So where is the evidence? I dont think there is any is there? There never is. Master Kenjit~ |
(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...👍👏😃 |
