What is the bass difference with these different cab volumes?

So do I, so I can say I've been there. There is a certain something that you won't experience if you try to take too many steps forward in theory without stopping to try a few things 😉


What acoustics are we talking about?
For sure and nothing is folded or built necessarily in the way it’s represented or responds and instantly somethings are diluted if this isn’t acknowledged or understood.

Couldn’t be more obvious in the perfect folds of an offset driver transmission line they also three actual segments nothing else?

And in radians is where you figure that out and they add up to a full circle even though he’s using centimeters it’s quite confusing an odd how that works but it does every time and it’s exactly where the pressure notice for the harmonica feels it never steered you wrong but the same time that’s not only extending the bandwidth that’s clearly making a difference in things that not even really represented at first?

It’s but isn’t being represented otherwise in doing it in any other way that begins to get noticed I think?

Either diluting that by using advanced center line and just guessing at where things go instead of just making them go back in for three times exactly and not screwing around with nothing else or making a convenient shape otherwise cause all that is is a tall skinny subwoofer it’s pretty easy to work with but all that could be enforced with a small rear chamber that keeps it in check so the reflection is in fact enforced and it doeEither diluting that by using advanced center line and just guessing at where things go instead of just making them go back in for three times exactly and not screwing around with nothing else or making a convenient shape otherwise?

That’s when you start to notice there are absolutely positively some things to chase after and not just for extended bed with her for a full range but have the same numbers will still be represented in subwoofer if you look at the extremes of where they would show up if that was the case and if that was true?

It’s 86.4 Hz is where the screwed up begins if misaligned. But it’s 860 Hz where it will be completely annihilated if in a compound pipe with a shared exit is perfectly aligned. If you accomplish all these things it’s 360 cm total but it’s not 360 between the drivers. 300 from each and they split.


and there’s an a ratio where you can directly correlate a rectangle into its attributes that it has versus a sphere. Do you have to use a higher order mats for that and I for I can’t find where I have it written down, we also have the book where it explains it and shows more of that I just need to go get it at work… And we can see how it is going to pertain to waves that are either standing or propagating outward The sequence of locations unfolding that are already there in already exists thanks for the fundamental 1/4?
 
So many of my designs over the decades are/were somewhat contrary to EDP, so don't even think about it, much less recommend it and frankly, glad I was spared knowing about it till it was mentioned sometime after joining the WWW DIY audio community.
EDP And quarter wave don’t belong in the same sentence it seems?

I don’t understand it whatsoever I have never looked at it because it was always a deterrent in the wrong direction it seemed? Then again it was never fun to just make a base reflex enclosure. They’re too easy and too quick to buildand you had to go find something else to do after the fact to stay busy again and again….

It seems however thay kind of thing pays off ?? things that no one else was looking at like little details in existing things to make them incredibly improved?? The idea of to offset driver entry transmission light speakers both need a 360 cm pipe. But one where the exit is at 270/90, not zero or 360., It’s important to note that because that’s where all the information is that it’s missing otherwise? And as soon as you converted to radians in all those parts you realize what’s 034920649 which was all about? And then you realize all kinds of other things because the same thing becomes the number and higher orders from each end of two closed pipes which must line up in higher orders and those higher frequencies show up precisely in the same place that they disappeared from. In the offset driver version.

86.4 Hz if it’s not align perfectly in the fourth order or TH version of a TLOD. will be the exact location in the 360 cm pipe ( compound parallel with a joint exit ) where are you find 860 Hz at 8600 hz Everything in between all the way to 19 780 are gone if it’s not aligned perfectly will be the exact location in the 360 cm pipe where are you find 860 Hz and 8600 Hz and not like anything else it’s gone -990 DB.

But the same time you’re missing for hertz at every interval of that and those add up to the same exact sequence as the Fournier transfer of the other frequencies that are rippling alongside that in the normal fashion at 3But the same time you’re missing for hertz at every interval of that and those add up to the same exact sequence as the Fournier transfer of the other frequencies that are rippling alongside that in the normal fashion at 32, 96 192 384 over and over again..

If you use 345.6 m/s you get frequencies and centimeter distances that are directly related to the speed of light in that screwed up by the ideal gas law equation it seems.

iPhone response uses 34 4 m/s some of this would be more obvious instead of impossible to understand or see connections. Hyper physics pipe calculator for residence shows incredible amount of information because you can change the speed of sound to the speed of light and you can change it to anything in between point is that’s the Pythagorean theorem that shows up at the speed of light and and then a 2550 three-quarter and onHyper physics pipe calculator for residence shows incredible amount of information because you can change the speed of sound to the speed of light and you can change it to anything in between point is that’s the Pythagorean theorem that shows up at the speed of light and and then The same intervals of 1/4 2/4 3/4 and 4/4. Exactly as they do in a centimeter versus inch conversion 1÷254 and all those decimal points are holding the whole sequence of numbers explains how to do all of this and always have. I had to convert it to frequencies there is no quick and easy way to see but the connection between Frequency radians of a circle and acoustic shapes as rectangles that are describing and contain the functions of spheres sine waves grouped and folded appropriately and only in the way they should be three. Three and one on parallel versions of them.

are you still start at three to one from one side and three to one on the other side there just happens to be two more segments in between. It all works out and you only change the cross-sectional area at that halfway point no other place so 1/3 of the long side and the entire short side or exact same thing.

The numbers are already in the unit conversion to centimeters 1÷254 and that is already eight divided by pi pi divided by eight and by divided by six is 30° or 5238 in radians but that those numbers right there are cute all of this so is 432 in 12 hours and 864 in 24 hours the connection has to be jumping through the same hurdles as the volume of a sphere is a function of eight although it looks like a bThe numbers are already in the unit conversion to centimeters 1÷254 and that is already eight divided by pi pi divided by eight and by divided by six is 30° or 5238 in radians but that those numbers right there are cute all of this so is 432 in 12 hours and 864 in 24 hours the connection has to be jumping through the same hurdles as the volume of a sphere is a function of eight although it looks like a 4÷3 times pi, that’s 240° and 360.
Eight and 12 there’s all kinds of things all over the place they don’t have a specific answer but put them all together and boom!!

i I think that nobody looks at some things because they look hard at first or they look like the wrong answer or worse they’re a pain in the butt ? Does the things he had to do in order to figure anything out in a matter what and I always will be . I don’t know that it will be ever obvious unless you go there and work your way back that you’ll see how the full range speaker becomes so perfect with a set of situation scenarios that will allow it to be but they come from the same idea in the same exact math in radians of a circle that they do it all of this including ugly silly ridiculous things like Paraflex or roar?

I look really bad on the surface but they had no nothing going on except somebody’s post to buttons in his numberI look really bad on the surface but the I really bad in many many ways. That stuff disappears incredibly as soon as it’s given a sequence based on 05238. So is the offsite driver already as well it’s 104.76 and that’s 300 cm times 03492. It’s all transfers into the 360 cm compound version and if you like anything about full range TL he might want to look at the ugliest nastiest subwoofer idea ever come up with that actually isn’t as soon as you appropriately format it in the same way?

enforcing these things to expose themselves so there’s a cosine and a sign wave at all times?? . This scenario where you have a peak amplitude and I both ends or across the X axis at zero when you plot that. If you fold it only those locations and it within the cabinet you have 360° and the hardest most complex version of the cabinet which will expose all of this in a way that is essentially a super high order off-set driver entry quarter wave pipe.

you’re gonna eat up everything that That would’ve but you’re doing it in so many ways that I don’t think any of us recognize because we’re confused with these weird looking Paraflex ideas that are all screwed up and not addressing things in the math of radians.?!

The speed of light in radians or the number three or 30 or 300 in 360??

That’s the easiest way I can explain it but where it’s all at and shows itself in the same way that 03492 exposes anything for an awesome driver entry to a certain extent ambiguously in the way Martin King was doing. Furthering that concept produces something entirely different you get both but it’s not that hard it just seems like it would be such a mess

A long time ago some people were working with the Bose wave cannon and that’s all jacked up we all understand that not only that but any space in between is gonna be offset in what side of the single you guys were using the Pythagorean theorem you could sort of sort that out?


using the Pythagorean theorem you can find every single location in the entire universe specifically our solar system because it’s not the information in the subwoofer that tells it’s the same exact thing as the centimeter already does in his reciprocal.

Everything you could think of has a reciprocal frequencies and centimeters and vice versa as well?

if you look at 345.6 m/s is the speed of sound you would jump through a hurdle of math and junk the ideal gas law that confuses everything for all of us and always will they’ll be no connection there just decimal points and garbage to confuse it?

I think you

Something of the above stirred recollections in the hazy lumber room that passes for my brain of an essay by Steve Deckert over on his website: https://www.decware.com/newsite/DECWARESOUND.pdf

I note that Pythagoras, base 60 and 432Hz all feature heavily, alongside the malign influence of demons:

One of the things that lead me to discover all this stuff about 432 Hz was coming across an article about how the tuning was changed in the 1930’s [sic] to 440 Hz. Very little explanation as to why that particular pitch was chosen as a world standard, but the simple fact that this new musical scale no longer contains a single note found in the chart (making virtually everything I’ve written so far pointless) could only be the demonic actions of a shadow government.

The great thing about standards is there are so many to choose from.
 
Well, that's everybody here then. It's just a shame it wasn't noted in the first place as it might have stopped an inordinate waste of everybody's time.
I did not deem it a necessary point at the time of writing, apparently "everyone" has been through a thing like that one way or another so whether or not it was intentional seems pointless. Got a bit more time now so no worries on my part, not that I think it matters much. Besides, hindsight is always 20/20.
Interested in the scale standard changing, I should dig a bit more on that topic.

If you play with an equalizer you'll find that we have a hard time hearing 3 dB difference down low, so anything audible will be due to how each energizes the room, but in general, better to choose the most power efficient alignment at 'x' desired tuning or based on the driver Fs if it's low einough for the app (Vas/1.44, tuned to Fs).
Could you please elaborate? Cause if I change anything 3dB in the low frequencies - I hear it clearly. But if it's with a Q of maybe 10 or something super high... then the difference is so small that it drowns in the mix. But changes with lower Q values, is very much audible in my system. Where I have multiple subs( four ) and 3 way fronts.
 
If we go to Denver Colorado with the speaker/test tones and then we go to Egypt right now can you play the same test once we clear that up at 440 and 432 real quick?
Better yet, we can take it to the math and see how they are directly related at 44÷7×10 log 10 scale which doesn’t mean anything until you realize what 432 then is as the sun or seconds in a day or the diameter of Jupiter or the speed of light or speed of earth which are 1/10 of each other right now as well or what in five seconds 500 seconds versus 1000 seconds either one of those are and how that is everything right there or somehow is all spelled out in 1÷254. ?? Self eight divided by pi or pi divided by eight but look at what the differences between pi or 22÷7 or pied based exactly on the dimensions of the sun right now on any NASA website?

I think the key phrase GM made there (in terms of what you're asking) was 'so anything audible will be due to how each energises the room'. Under anechoic conditions it's difficult given our falling hearing acuity with frequency; ditto for most stereo setups. With four subs (presumably in something akin to Welti & Devantier's work with Harman?) you should have a rather more even in-room response than most though, so variations in LF SPL are more likely to be apparent.

You're more into numbers than me, could you calculate the most likely missing 9 notes from the PDF Scott linked to?
Referring to this section here:

So we have 396Hz, but what are the remaining 8?
I will make something out of it if you apply some of your brain power.

Edit:
I found this bit here:

I partly accept this explanation. But I have made many corrections with a DSP in a lot of different scenarios, where we had to reconsider the value of Q to make the level in dB to actually be audible - meaning - proper use of EQ is needed to actually get the difference that we seek or expect.
I also heard many that claimed +/- 3-5 dB through 500 to 10.000 Hz... was plenty fine.... but to my liking... +/- 1 dB is way better. I never found that sterile og "cold"... I simply find it neutral, and neutral makes me forget the speaker and focus on the music.
Not only that, but I found that many speakers play absolutely fine - as long as you don't push a boundary that exceed a given driver's performance limits. Which is why I usually prefer a bigger subwoofer playing a little lower, than a smaller one clinging on for its life 😀

I heard a Lowther with 6 slot loaded 10" opposite mounted woofers.... that was fun! And the cab was not even that big. Again - it depends on how much you love bass and how much space and SPL you want. But still... even big systems can play low... just with much more fun - IMO 😎

I don't quite see how it will fit with a fixed pitch shift, quite cumbersome to have one synth per note. Guess I can understand why that "healing" music is so boring.

174, 285, 396, 417, 528, 639, 741, 852, 963.

Edit:
Think it was pitch 0.9818 checking...

Apologies for the thread derailing!

Well, I'd be intrigued to know how numerology, astrology and the zodiac (all pseudo-sciences with zero basis in reality) are only 'a little bit wrong', rather than being the twaddle they in fact are, but as you say, the thread is a mite derailed, so possibly better not to take it further through that particular looking glass. 😉
 
I do find it quite interesting that 396Hz (liberate from guilt & fear) is eerily close to the modern G at 392Hz, fits well in hand with "Just a groove in G" feeling so liberating.

Edit:
And you see he's holding a pitchfork! It's real! G is as close to the Demon note as we get with the modern scale! 😀 YAY!
