My mans over here looking like a futuristic cowboy, and sounds like he's talking about building some crazy spaceship powered by sound.

The way he explains sound shows why he's great. His dedication and enthusiasm is so genuine. I wish he continued his KZfaq channel.

I used to get hired for a surf film festival because I promised they would feel the crashing waves as if they were in it. And they did. It was outside, maybe 1 acre, maybe 300 people, but dispersed coverage with a few delays, and the subs did the job. But that was thee years ago and I have been obsessed with steering subs for about 18 months. I wish I could do that with my current knowledge and really try to replicate nature. I’ve been at this mixing bands looking for that chest imploding kick for 25 years and thought I was at the top of my game. Wrong. There are some compromises, but actually less compromises than with the old conventional sub setup. We all just got used to the pattern, without realizing there was a pattern. Many years ago I did some outdoor gigs but in the middle of downtown Charleston. I lined up all my subs across the front of the stage. Played some Massive Attack. Ladies 1/2 block away (this was an art festival) came running up complaining that their paintings were falling off their easels. I asked what that had to do with me. I mean, they didn’t sound outrageous on site. It was weird. Sure enough, I had my assist stay on the Phone while I walked WAY back away from the stage, far away from where any audience would be, and I honestly at the time couldn’t really tell what was different even as I was standing next to the paintings. Had my man play “Pray for Rain”, and I asked him to push it a bit, wait and listen, then more. Well as it turns out, the opening notes D(72hz)A(@54hz), G(@48hz) resonated like crazy up the center. The subs focused narrowly instead of wide. Adding subs width wise actually narrowed the pattern. Now I see the light. But you do get some odd phenomena on stage if you get the rear lobe wrong. What would otherwise be obvious acoustic guitar or Tom ringing, feeding back at low frequencies, will make you nuts. I high passed the vocals more, from 160hz up to over 200hz, and it thinned the vocals too much. Same with the acoustic guitars. I had the toms gated tight tight. Some weird shit. Got rid of it but the mix suffered. Who knew we could steer subs. Now I’m doing it home, such that in my room-over-the-garage I have two very old double 12” Peavey downfiring, non-ported, subs. Both facing forward, as Ratt swears that you shouldn’t have to have speakers fighting each other, even though that is actually what is happening at some frequencies and at certain positions you can hear it, and I wonder if that was the cause of the 90-200hz ringing. If you stand just to the side of a near dead on but not quite sub array, youlll feel like you’re getting pushed back and forth in the same position, kind of like and undertow in waist deep water. The lower current is trying to pull your feet away while the upper current is trying to take your torso elsewhere, hence undertow drownings. Waves are a hell of a drug, and I’m super high on them now. I also notice how my lighting “arrays” made a narrower pattern. I got some LED strips about 40” long each hoping to wash the stage. Wrong. The ultimate reality is that some, no ALL waves, depending on harmonic relationships, distance, gaseous flow, and fundamental frequency, can sum or cancel each other. I used to have a 16 cab EAW KF850 rig. 4 over 4 aside. This one Scandinavian guy comes in and explains to myself and my crew how we could UNPLUG the outer cabs and get wider coverage. It’s all because that 12” at that frequency at that distance away from another source is making the exact same frequency at the exact same amplitude at the exact same time, BUT, NOT at the exact same time most of the places where you could stand and hear them. Which in turn cancels certain frequencies at certain distances away depending on where you stand laterally also. Too much. Guess what? Vertical line arrays have been abused and compounded the problem in the linear distance field. Get it just a hair off, even perfect. and there will be tonal compromises depending on where you stand, which is supposed to be the opposite of how a line array is used. Sorry I’m out. Sorry I mentioned 12” in the KF850 reference but there is no 12”. Only 10” mid horn loaded and 15” behind the horn, also horn loaded. The 15” is also partially baffled. Which is baffling. Nowadays I understand why, but Kenton Forsythe is truly a genius.

i totally understand wearing goggles, no dust off the ground in your eyes

I’m a new fan of Mr.Rat, as a mobile DJ I’m always fascinated to have spectacular sound on the dance floor. This guy definitely has a passion for sound. Respect to the 🐀 ✊🏽

People like Dave who dive deep into their craft always bring push the limits. Great video! Thanks.

gotta get myself some bass goggles!

Dave Rat has lots of interesting content on his own YT channel where he demonstrates all kinds of live sound principles and techniques.

And here I am trying to get my 2.1 home studio speakers tuned properly to my room...

"Bring less get louder." Genius!

Thanks for the video, so much info every time he speaks. Great audio quality btw!

Dave Rat is a legend.

This guys a fucking genius. Here I am building subwoofers in my basement using conventional drivers compound loaded using stacks of crown 500x's (5000's and 5002's) to try and achieve the same thing. Thermal compression will forever be a problem. As the venue goes on for hours and days, voice coil drivers suck.

My boi finally went digital. Proud of ya

i would love to go to a virtual riot show with these bad bois!

These speakers do not use a voice coil and cone but instead a servo-driven DC motor. I remember someone else doing this 30-ish years ago but can’t remember who.

this man is a unsung hero....

In 1974 MGM and Cerwin Vega teamed up to create Sensurround sound. Sub woofers that could hit up to 130db's between 16hz & 32hz. I saw earthquake in a theater with that system and have never felt bass like that since.

Rat sub is leaving wave rly because it has a light tiny curl on its back but I thought that back was a lockness then became a E squid mouth Is this why the swift darted it and left aswel?

Awesome I love audio!

This guy is a legend !

What a humble legend!

I love this guy

The man himself! Take notes fellow mortals.

I'm liking that idea subwoofers going below 30 Hz. It's definitely the bass drum "beat" that gets the booty shaking. And those low frequency bass signals that pass through your body that feel oh so good. Music should be felt, not just heard! lol.

Is that model of subwoofer also called "Super Duper Sub" "SDS30" and "SuperSub"? (Not much info on ratsound.com) More text about SDS30: www.lightsoundjournal.com/2018/06/16/m-force-and-rat-sounds-supersub-at-coachella-2018/ Photo + links at www.audiomeasurements.com/?p=5540

isnt that the red hot chillie peppers dude?

I want to be his apprentice

This guy looks like he got his outfit from Binco discount store.

I didnt go there but from youtube videos i hear through youtube (the supersubs are insanity)

Love the WW2 era fighter pilot goggles.

“Low frequency is the key to connecting the band to the audience” That’s what we tell our bass player in my band. But we really unplug his amp before the show so we don’t have to listen to his wrong notes. He is really just there to do hair flips and look cool.

Are these the powersoft subs?

All this talk about Super-Subs is making me hungry

Dave is the Alice Cooper of the Sound world his advice has steered me right does anyone know if the SUPER DUPER SUBWOOFERS were used at Coachella 2020?

That’s funny, I’ve seen some guys that compete professionally in car audio we’re making enclosures like this 15 years ago.

great system

I don't know about lower. The Bag End ELF subs (supposedly) went down to 8 hz. The really old movie "Earthquake" was shown in "premiums" theaters with rows of Cervin Vega subs passing, IIRC about 12 hz.

Dave is a man after my own heart. "Hearing the same song but better than it has sounded before. I've never heard anything like that." I like he always is pushing the envelope of "sound" and frequency. Tesla: "If you wish to learn the mysteries of the Universe think fist in terms of Frequency, Vibration, and Energy. Frequency is the key to many things beyond music. Especially what is known as Resonant Frequency. As everything has a resonant frequency, and applying the objects resonant frequency to itself will cause that object to disintegrate. Think how that could and should be used in treating disease without hurting the good cells in a body because they would have a different resonant frequency and would not suffer any damage. This is how ancient healers actually "healed" people. Through frequency and sound in ancient times. Music is healthy for you. And is the only way to stimulate the soul.

Who did he work with for amplifier design, lab gruppen, powersoft ,crown

This dude is so high I can’t even see him

I love rat

Nice video... please is there a way I can contact Dave Rat directly..... it's very important

I’m so glad shows these days are above 110db. All this tech sounds great with bleeding ears

My hero

I would like to hear em som day but probably to far away from Germany... That Gran Turismo 5 intro music.

You solve one problem three other appear.

Is he sitting on a horse? Stop image stabilization 😂

wow idol

who's manz is this?

Coachella stages of rat sound by dj palace

cool goggles dave, you riding in a motorcycle side car i take it?

That dudes in charge? I hope he spent as much time on the sound as he did his image.

BBC test card Carole Hersee and her doll at 1:09

300 by 300 is the size of a walmart.

Whammo Air Blaster? 🤣😎

Was he expecting a Sand Storm to suddenly hit or something ??

Bose Arenamatch FTW

why is he wearing safety goggles ???????

I like JBL

pied piper hat.. watch out fr your kids.... rat sounds... get it

“SUPER-SUB” now THAT’S what “I’m talking about”....dude you need your own KZfaq channel. Although, you realize, there was ZERO input, talking about the “midrange”. Guess you’re, “ALL ABOUT THAT BASS”

Super sub super sub super sub super sub. Rat likes his super sub Did I say super sub.

What the hell is this guy talking about?

Why are they having so many sound issues in Coachella? Why isn't ATK audio not doing Coachella?

its a shame coachella doesn't play any good music to really test that soundsystem

It's a shame they play such shit music through that lovely system

BOSE WAVE CANNON ... well 140.Db at 15Hz What's not to like (In my set up) I build 4 replica "" cannons "" for a club in Aalborg ..!! Deadmou5e did his after party at that club !! They phoned to get the ""db limiter remooved "" well i went in and removed IT .. he then played 9hrs We had som interesting talks about Sound .. espesialy talks of bass and ""hair raisin effeckt .. as goin to churtch with a huge organ and they push the deeep pipe !!! You can't heare IT but you get a religius aaahmen experiance whennyou feel the loooow looow""

Why does he keep saying cycles? The industry accepted term is hertz.

I don’t like the terminology of “super subwoofer. Look at spl walls. And this is a super subwoofer?

L acoustic subs are for sure shit compared to m sub L acoustic subs don't sound good they lack impact heard them. Don't know why they are using l acoustic shit systems this guys can afford anything.
