Jessie, another thing is that there does not appear to be an actual "standard" tube pin diameter for a given species. Add to this the mediocre initial quality of the Lamm sockets and you have a less than ideal situation to begin with that cannot im...

I have been involved in moving several galleries and a museum and I can tell you it's all about the people, as opposed to how the company they work for bills itself. Big donors would have heart attacks if they saw how stuff gets tossed around and ju...

[quote user="jessie.dazzle"]Assuming situation 2 is possible, receiving mid-bass primarily as reflected sound, one would have to take into account the reflected path of that sound, and how it describes the mid-bass part of the image, relative to the ...

Thanks, msaudio, for sharing your experience with Aura and Hartley. I do not have Hartleyes. I heard them I think twice but person the people did not try to get out of their playback anything that I care, so it is hard to say anything. In contrary I ...

[quote user="Romy the Cat"]What however is very practicable is some kind of sealed TT mat of 2-3 cm tall, fully filed with mercury. It would be 10kG of inertial mass – it might work… The question is how?[/quote]Ah, this is a GOOD idea! Wood would be ...

[quote user="jessie.dazzle"] I am certain that the depth of such an experience .. is very dependant on the system+room; whether something in the system can bring about a more crystalline state of mind… I will be very curious to see how this 7th chann...

I spent today some time to finish my Multicell as I am not able to look at it if it not black. First that I discovered is that it is irrelevant how it painted at throat as horns is so deep that it dark in there anyhow. Jessie’s idea to fill up the c...

Jessie, your post catches me thinking about multi-channel driver matching, as well. I am not familiar with the Fanes, but I wonder if simply throwing more power at them would make them nothing more than louder, so they would then "match" the res...

[quote user="jessie.dazzle"]The Velodyne SMS 1 will allow you to do just about anything, up to 200Hz. [/quote]I was the Velodyne crossover into the game yesterday. To my surprise it not as convenient as I thought. The high pass filter is not defeatab...

Thank you Ulf and Jessie,
I can't wait to get this started. Jessie I am going to send this plaster spec to my supplier and see if I can find something close..
In the past I would use plaster for creating a wax form.. then put the wax form into a s...

Is it possible that there are better and worse sounding versions of iTunes?Since 2004 I've been using iTunes together with a Mac computer and the very addictive Wavelength Cosecant DAC as the main source "component" in a system consisting of horns dr...

You might also want to try stiffened felt, which seemed to work "as well" as the paper for me, and it is easier to form. Just saturate the pre-shaped felt with runny "paste", whether gluten/starch or methyl cellulose, milk glue, etc. Spray starch ...

Thank you for the lesson in metalurgy, Jessie (seriously). Actually I have no reason to believe that the bronze horn in question rings "like a bell" "when struck" in the same way a real bell rings when struck, so that does seem to put ...

Well, Jessie, I think you're exercising a wishful thinking but you have, I think, a wrong subject for your thinking. Neither Lamm nor any other high-end manufacture care about result as a concept but rather a result as product. A product b...

[quote user="jessie.dazzle"]It is interesting to note that the evaluation tool shows lines radiating perpendicular to the curve at any given point, just as the sound wave is supposed to be oriented as it progresses along the horns length. [/quot...

Well, congratulations, Jessie, and welcome back to the Surreal World!For a while there your posts were reading like a dime novel!I hope you will try the doubled ML2s to see if you also hear the unusual effect the ML2 has on bass.What I get is th...

Mouth size is the one dimension I've struggled with most.As of the present time, I've deduced to use a mouth size that may prevent me from achieving the target frequency of 40Hz, and instead produce a frequency of about 55Hz or even 60Hz. I can...

Hmmm, are you sure that you do not do a mistake?
Jessie, I do not know how to say it but looking at your last picture something does not work for me. The hone that you made are elegant and graceful but painted in glossy black with that very rough st...

Jessie, as it happens, I find my own best listening position varies somewhat these days, depending on what I'm listening to or for. For the best overall energy in my fairly energetic room, it is with my ears about 1 1/2 m off the...

Jessie, the "Horn Free Lunch" derives exactly and specifically from "efficiency" registered at frequencies much higher than those ultimately required from the driver in the horn speaker. The horn is there only to provide "gain" at lower frequencies...

[quote user="jessie.dazzle"]From this and from the mention of 3/4" plywood, I deduce that the "curved" walls of these horns will likely be described by a series of facets (flat planes). It is said to be okay at these frequencies; this must assume a p...
