??? Historically, the point was to fill in missing (sub) harmonic fundamentals (Fs) to (re) create a more life-like audio/visual experience be it a low B pipe organ symphony recording or action movie LFE since the lower the (Fs) the wider its (perceived) BW, a big plus for those of us that typically only had an otherwise ~ 20/50 - 12 kHz system.
This is what I was hoping to do and sneaking underneath everything with a super subwoofer(infra) because of how much you have to give up of that low end as a result of attacking the upper subbase region with the dual parallel types of approach which themselves have a signature and very pronounced punch to that area of base that once you hear it it really has a potential to be the perfect Kickdrum as if you were literally sitting in front of the percussion set up at any concert. It could be excessive and even uncomfortable to the inner ear so it has to be dealt with to be reasonable but at the same time one cannot deny especially if you like that sort of bass in that area that there’s something special in these cabinets that is allowing us to experience more than others tend to give up.
I think that may extend all the way into the Keystone the Paraflex the roar and probably a couple others. There’s some thing to the offset driver entry version as well I don’t know if it’s quite so sharp but the whole point in some of these is once you can get the distances in your folding perfect in a repetitive sequence that doesn’t do anything but support the fundamental and smaller and smaller parts of it something is definitely changing in there as opposed to a base reflects cabinet or whatever things people just lump sum and toss together without regards to standing waves or potential usefulness of that distance as contribution to a low pass filter effect by using the position of the actual node for the harmonic. And this point of fold abd /or driver entry in the cabinet. And from both ends in many designs this can create oh unification of all of those things too which is only expressed in the details of simulation you can see far up out of the past band something special happens. Probably for another discussion as it’s unique to only a few designs seems
What once was 00349206349 (Thats 20/360* , is now in a compound cabinet 05238 or 30/360 with with 300 separating the drivers.
6.2857142 (360 cm) is the total and 5.238 is 300 cm Between the drivers and .5238 is the distance from each closed end , from a zero and 360 essentially . So its 1/12 and 11/12 of a circle if using that as the basis for the cabinet design. Which once you do everything works out beautifully. Can you can see that Further using circumference equals two pi R and using pieces of radius to define those arcs as a radian to divide up these numbers as angles or what they are in degrees as centimeter?? it works both ways. You can see it in different designs were both numbers can affect the other. But since we’re not familiar with radians we don’t use that for much of anything anymore it’s long gone with navigation to GPS nobody’s familiar with that and the numbers to seem odd to all of us as a result..
Originally 03492 in a 300 cm cabinet was 104.76 cm. ((It’s 20° and 300° and 60° in a variety of explanations numerically describe them ) Either way it’s still The absolutely perfect position to put the driver entry in in the ODTL mode. And it’s giving it the correct cross-section for the drivers TS parameters appropriately that all worked out excellent every time.
And the same idea then becomes the alignment to which you want things overlapping in the compound cabinet and the same approach has then much greater advantage in that acoustical output and low pass filter effect it will once you’re incorporating it.
And what you get out of these things like the Paraflex that normally were very sloppy and nasty and places that require more recently as they find huge amount of stuffing and Band-Aids to fix things is that those are all gone and they don’t even need to be there it requires a little shuffle in the layout that might not be PA friendly but the numbers and the results are like a small oasis in the desert of issues that previously were big issues as soon as you put a paraflex in a boundary condition a lot of nastyStuff started showing up that never did I was notice before and of course not many people try to use those in anything but the PA application and the more and more people would the more we would run into the idea that these things are horrible and burn them in the dumpster fire.
But as it turns out with a little bit more investigation they don’t. They just need to deviate entirely from the original version created for PA. Because that is a scrambled egg if you look at its results and how it simmed and folded and design it’s chopping up a disaster that shows up more and more at certain frequencies that have to somehow run into each other in the cabinet and simply do not agree they are colliding inappropriately from their endpoints came from and That can get out of hand quick room that produces more of the same or extends the problem so to speak.. small room obviously being the absolute disaster but also the place to learn the very most about this.
it’s always in the same area it could be an 86.4, it could be 93.75 and 108 or so. It really depends on the details but
Those frequencies that oddly given the right arrangement get nasty inherently all the time.
until you fix it and then it seems to have all disappeared. And then it just seems like the honest to goodness approach to a plain Jane transmission line that happens to have one piggybacking it that just gives more output because it’s an acoustical advantage nothing more nothing sloppy nothing weird nothing strange encountered. And nobody has the damp things out to the point where they’re compromising with their already trying to get initially.
The only thing left to do Is the normal stuffing that one would want to do Because their preference or their ability to hear boxy sounds or whatever I don’t know I can’t speak for other people’s hearing but there are things that don’t matter what I end up throwing some some of that party for him places just dial in things and the smallest level not huge catastrophic disasters that need that typically because they shouldn’t unless you’re coming up short on the other end or you’re forced to compromise things in order to fit the design into certain size shape etc. which no one can avoid and that’s always going to be a problem for all of us if we have to do that.
There’s absolutely positively something that has been missed . That is that number 05238 it’s the same number as the volume of the sphere is when radius is .5 versus .1
that number goes on to be the swing of the panel and 30° in one second
That number is the basis for everything in the tire universe and not even only acoustical advantages but the mathematical location of planet earth is relying on that exact number to describe its orbit and it’s hexagon or dodecahedron points of interest laid upon that mathematically are exactly over and over again the mathematical orbital mean of our own planet.
it’s the same approach as a 03492 which has been a number that both yourself and Martin King were using in everything when you wanted to drive or entry point to fill in that harmonic.
But that’s a number and the ones he incorporates entire orders becomes a number to find the exact location in our own existence in the space and time if you look.
And whatever it does is our speaker designs is undeniable as well. And more than I can type here is about three or four pages of simple basic math that all of us with digest no problem but that spells out the connection between all of us and our own existence in our own solar system and the galaxy next to it and even more.
It’s the same numbers and even more so the numbers within all that that you can find a simulation further it to the most amazing detail it’s almost hard to not choke up , and wonder why this was hidden all this time. Not discovered along the way except for the fact that no one was able to look there simply wasn’t for a reason up at all recently.
It’s not for a combination of things in peoples ideas from different areas all coming together with a man providing us the ability to looking all in anyway I possibly could together they created a narrowing down of things further and further into The island the little tiny speck where it all came together at.
literally half of that number is the location in degrees of planet earth and 3/4 of it is Mars. It’s an absolute is the definition of the speed of light as it’s on wave form if it had a sine wave hypothetically speaking with a zero at an X axis and a pressure velocity Max minimum either end in between.
