Hi everyone, Dennis Foley from Acoustic Fields. Today we're gonna talk about the resolution
of dynamics. I try to break each part of resolution down into different parts and explain each
part and hopefully then you'll understand all this craziness we have to go through to get
to it because resolution is a multi-level issue. It has six or eight different levels that really
have to be satisfied before you go, oh wow, that sounds really good. You know it's that
aha moment that you look for and that's you know that 80-90% resolution. So that's kind
of our goal. Fundamental strike sound, it's the head of the energy. It's the beginning
of the wavelength let's call it. And the harmonics, that's the life. So if this is the strike,
this is the life. And then all the harmonics. are parts of its life that it lives. So you
can think about it as a living wavelength. In a way, if you think about it, maybe I need
to get out of the studio a little bit more. But anyway, low frequency fundamentals, they
must have a very linear attack and decay rate. Because the attack is really important, but
if you over absorb to get a real tight attack you're going to hurt the first, second, third,
and fourth order harmonics. So you got to be careful when you when you're designing and
using absorption. You kind of use the fundamental, the head, but you also have to keep in mind
the harmonic tail because if you just design for the fundamental attack you're probably
over absorbing in the harmonic side. But that's where diffusion can come in as a tool. to punch
the harmonics up for you. So you can over absorb and get definition and then you can bring diffusion
in for the harmonics and make the room sound larger. So boy, it's a win-win across the board.
The room must be pressure balanced everywhere. Here, here and here. With length height, it
has to be pressure balanced. As you're filling a container full of pressure, Take an air hose
and plug it into your room and fill it. It's only going to hold so much pressure, right?
Just like your tire on your bike. You can over inflate. Well, people do it all the time. Well,
I have four 18 inch subwoofers. Really? And then I ask them the room dimensions and it's
a closet basically. So see this makes no coherency at all. So factoring out, you know, all that
other human stuff, but you cannot have resolution. without this pressure balance. Because modes
are like three, three and a half feet wide and they're everywhere. Cross all the walls, cross
the ceiling, floor to ceiling, then they slice the room up tangentially for four across four
cuts, two cuts for axial modes, four cuts for tangential, six cuts for oblique. Lot of energy
being messed with here. So here's the thing, you gotta be willing to give up 12 to 16 inches
to treat the low frequency, almost in any room. It's just the way it is. We have the world's
most powerful technology and this is what we need. Those other people can't even come close.
get the performance of our carbon panel you would probably need 60 to 70 inches of building
insulation. Just to get down you wouldn't get any rate either. That's why it's all nonsense.
Only our CAW system can achieve 80 to 90 percent resolution in the low frequency side. We can
do it. We'll guarantee it for you. Do before and after measurements. We don't care. Pick
your own engineer. I don't care. We'll fix it because we're going after the room modes. every
14.5 inches, that's the distance between the stud spaces. Nothing can hide. Here's the beauty
of the CAW. We know that every wall surface have a different frequency and amplitude problem,
so we focus on the frequency and the amplitude. If the floor to ceiling has let's say plus
12, plus 13, we can increase the thickness of the carbon filter that goes inside and between
the studs. to go after that plus 11 plus 12. So we can tune the room every 14 and a half
inches, four walls and floor and ceiling. Think about that. That's pressure balance. That's
what you gotta do, okay? Look at the performance of our ACDA 12. Look at the percentages, 35,
60, 100. Look at the linearity. Okay, so reflections are foam technology, pressure and reflections.
Remember those are the two, look at the graphic here. What do you see, linearity 125 to 500.
Look how smooth it is. Took me eight years to get that couple million dollars. It's huge
for voice and music. That's how you get resolution. That's how you get resolution in the fundamentals
and the harmonics. You pay attention to all these different layers. And you've got to make
sacrifices. And you've got to decide if it's worth it. Most of our customers, I would say
all of our customers, it's worth it to them. Resolution of dynamics. Hope this helps. Thank
you.

And then don't forget about our forum. We have started a forum on our own website where people
ask questions and I usually get a chance every couple days to look at it. There's an interchange
between people on the forum and we'll give you real answers on a regular basis so that'll
help you. Thank you.
