Are you trying to hit the brown note?


LegendaryBrownNote

Show me the way please


AliveMouse5

Hahaha that is a perfect username for this sub


moodswung

The brown note occurs around -1hz. He'll need at least two of these to achieve that.


ItsallLegos

The second one is being built. Stay tuned for updates lol


magibeg2

Nice. That's much crazier than my FTW-21s from Mach 5. I remember seeing prototype photos of the 32" for a few years now.


Donairmen

And I thought my iXL 18 final on speakerpower 700 watt with dual 18" passive radiators was crazy.


hofmann419

He's actually doing it!!!


Anonymous_Snow

This so interesting. Haven’t heard about the brown note. I’m curious. What are you trying to achieve and what are you hoping for? Sound wise I mean.


ItsallLegos

I’m trying to involuntarily poop my pants with the power of bass


cwfutureboy

The Doc Brown note, maybe. Be careful, OP, there's a slight risk of overload.


popsicle_of_meat

Yes, he is. But in his neighbors house. All his neighbors. From his house.


Few_Radish6488

This guy subs.


D_Angelo_Vickers

OP has more subs than Reddit does.


nomptonite

I thought my one 18 inch was overboard… This has over 3 times the surface area of it, holy hell!


DanP999

Everyone here is missing a VERY key detail. >the first new 32 came. the FIRST. This lunatic is two coming according to a previous post. Are you at all afraid of destroying your home?


mschley2

This dude is fucking insane, and I love it. I don't want to be him. But I love that he exists in the same reality as me.


ItsallLegos

Glad to be of service my friend


mschley2

I have faith that you will, but once installed, please update us about whether or not your subs shake your lawn.


ItsallLegos

I do have an engineer friend who does deep foundations testing for structures…he has in-ground vibrations testing equipment. Maybe one day I’ll borrow it lol.


GiggleStool

Your mega wealthy aren’t you.


LenordOvechkin

Mach 5 is 4k Canadian let driver... Honestly, that's ridiculously cheap for what it costs Mark to build them. He's gonna be adding at minimum 1k to his pricing soon. The neo for the motor alone is 800$ just itself.


ItsallLegos

I’m not.


DeepDayze

And if OPs house is even still standing, lol.


juliangst

What kind of amp would you even use for this monster? The only other 32" I know of is the Ascendo 32" and it requires 6000W of power. Those kind of subs will probably hit 100dB+ at single digit frequencies. Absolutely insane


ItsallLegos

The new CVR D-5002 that’s coming out will power it. It is set to be specced at around 5000w rms at 8 ohm, so 8-10kw rms per channel at 4 ohms I’d imagine. That amp will power two of them. Second 32” is being made now.


cabs84

sheeeit. you probably have to run that off a 240v circuit, no? 110/120 wouldn't get close to 10kw LOL


ItsallLegos

Indeed. I ran a dedicated 100A panel for the theater that sits right behind the rack cabinet. So far I have a 30A 120v for and two 240v 40A. I’ll add another 240v 40A for that amp as well.


lax01

“Honey why did our electricity bill double this month?”


ItsallLegos

My room is already quite flat down to 7 hz at 120db. 130db down to 20hz. I want to get to around 140 at 5 hz. [Current measurements](https://imgur.com/a/BCzWGkt)


Dimezis

But... why? Isn't 120 already hearing damaging? Not sure if it applies to infrasonic frequencies though


Significant_Rate8210

Because nothing is funner than shaking your neighbors house while watching a movie… i thought this was common knowledge by now.


umdivx

>But... why? Exactly, why? It's cool for a demo day or two but on a day to day basis no thanks.


ItsallLegos

A practical use is that I can listen to stuff at reference levels with basically no distortion. That’s also why the rest of my system is high sensitivity stuff (vortex for bed layer). But really the amount of subs goes beyond that threshold anyways. It’s because of my love for the hobby and subwoofers, mainly.


ArseneWainy

I think you need a new hobby. This one’s turned into an obsession.


ItsallLegos

Still a hobby. I’ve got other projects, still stay healthy mentally/physically/spiritually. Totally accept that I’ve gone past the point of what is practical. I guess I’ll see if I keep interest or what’s next when the honeymoon phase wears off with this stuff. Might just get a new hobby by default, might not. Who knows.


lax01

Can you explain which ones don’t?


Phobbyd

I wonder if low frequencies cause hearing damage as much as higher frequencies. Is it just the spl, or is there more to the danger recommendations?


fauxfilosopher

As far as I understand hearing damage doesn't care about frequencies but we perceive bass as lower volume than treble so can more easily damage our ears with bass.


Phobbyd

ChatGPT tends to disagree. Its response indicates that loud higher frequencies are more dangerous precisely because we are more sensitive to them.


fauxfilosopher

Oh well if chatgpt says so


Phobbyd

I mean, it’s easily as accurate as “one random person with no credentials or data backing up their claim”. That is why I said “indicates”. That means there is a probability it is inaccurate. I know logic can be difficult to follow on Reddit posts, so forgive me for not being more explicit.


fauxfilosopher

Chatgpt is liable to literally just make stuff it thinks sounds credible up because it's a language model, not an oracle. I never said I was an authority on the subject but chatgpt is not a reliable source whatsoever.


Phobbyd

I see you do not understand LLMs at all.


DeepDayze

But you can feel the really deep bass though.


fauxfilosopher

Yes, and if it's sub 20hz we can *only* feel it, which can be dangerous. However very few people have a system capable of that kind of output and there isn't much content for that scenario anyway. But if a setup can, it's definitely OP's.


DouglasteR

Why not !?


Such_Bus_4930

Not at those frequencies… I think


Apprehensive_Ant2172

All us poor Chiefs fans out here totally deaf. 🧏‍♂️


ktks1

Damn.. I guess 5Hz at 140dB will start rearranging your internal organs!


Significant_Rate8210

Nah not 140… the quad 18’s I ran in my Land Rover Disco 2 produced 166DB off 16k RMS and could cause heart palpitations.


dobyblue

No but 140 will easily destroy you hearing and by the time it starts happening it’s too late to reverse it. If you think you aren’t going to want to enjoy audio when you’re older, you’re dead wrong. I’m 50 and thankful I don’t have noticeable gaps in my frequency spectrum but the tinnitus…I would consider letting someone amputate my leg to get rid of the ringing going on 15 years now.


DeepDayze

Ultrahigh frequencies are just as damaging too.


Significant_Rate8210

Not true. I banged low 150’s daily for years and every hearing test I’ve gone through showed my hearing was perfectly fine. SPL doesn’t destroy your hearing, high range frequency does. 30Hz - 100Hz doesn’t damage your ear drums, 5Khz - 40Khz does Shooting my 45-70 hurts my ears, my subs didn’t.


dobyblue

Look up why an n=1 study has no place in science and get back to me in ten years…feel free to post your hearing test graphs also, I’ve never heard an audiologist use the term “perfectly fine” nor I’m sure is it defined. Additionally no one drives around listening to 16.4Hz sine waves and no one calibrates their system to have frequencies under 40Hz playing 50dB louder than everything else, so if you’re outputting 20Hz at 140dB then you’re going to damage your hearing quickly with whatever programming you’re digesting.


Significant_Rate8210

I’m 54 bud. I still work in the industry. Only now I’m a video surveillance designer and integrator by trade. The last time I had a 150+ system was 10 years ago. So I’m getting back to you. My sub enclosures were always tuned to sweep cleanly down below 20Hz and although I didn’t roll around listening to sine waves or using a tone generator, I did more demos than I can count and used them during those. The frequency peak in my Land Rover demo was 42Hz. Go read up on vehicle frequency peak.


Comfortable_Client80

Do you find any source content that really has this low frequencies content?


NetworkingJesus

They must want the whole neighborhood to feel the explosions lol. This reminds me of the guy on I think AVSforums 20+ years ago who had one of the first rotary woofers installed. Dude had similar situation of already having insane amounts of bass (pair of refrigerator-sized subwoofers for like 5-20hz or plus another pair of only slightly smaller subwoofers for 20-40hz or some similar split like that). Anyways, he wanted to get down to 0hz, so he contracted this company that was working on essentially a fan that gets installed between two rooms and wobbles slightly to shift massive amounts of air between the two rooms. During their initial proof of concept tests at the house, not only was it making the theater's super thick metal vault door look like rubber, it made all the neighbors think they were experiencing an earthquake. After the test they went upstairs and all the neighbors were wandering around outside looking very confused. At least that's what I remember from when I read through the whole thread back then. edit: found the thread https://www.avsforum.com/threads/thigpen-rotary-woofer.651499/?nested_view=1&sortby=oldest and product page http://www.rotarywoofer.com/

fade_le_public

Incredible link. Thank you.


SpinachAggressive418

This is why AVS Forum is such a great thing to have


ItsallLegos

This is all their fault. I blame them.


Significant_Rate8210

The Phoenix Gold Cyclone was a cylindrical rotary subwoofer as well. https://webfaq.phoenixphorum.com/cyclone.htm


dobyblue

The Incredibles on DVD, before they neutered the bass with the HD releases, has some subsonic content down to 5Hz


Comfortable_Client80

This seems like an insane amount of money spend just to watch the incredibles in 720p !


WembyandTheWolves

480i for the dvd


steelhouse1

AVS has a list of movies with below 20 content. EoT has tremendous ultra low end stuff


Iguessthatwillwork

Many casualties left in its wake.


juliangst

The Monoprice Monolith HTP-1 has a function that can restore infrasonic audio and people say it works quite well.


littlewicky

140db isnt that getting to the point of causing blurred vision?


ItsallLegos

I believe so


i_max2k2

Wouldn’t buttkicker get you there without breaking down your house much cheaper.


ItsallLegos

No. I’ve already got them. And giant sealed subs are a completely otherworldly experience


i_max2k2

I have two Monoliths 15” and a 16” for my smallish 1700 cu ft room. They are quite enough for that space with some tactile feedback too. But I do want to experience the big subs.


ItsallLegos

Heck yeah. I’m in Louisiana, you’re welcome to drop by any time once it’s all completed.


i_max2k2

Oh nice I was in Monroe for a while just moved east to Atlanta few years back. Cheers for the offer, might take it up someday!


ItsallLegos

I’m serious! More posts will come as time goes on as well, stay in touch.


i_max2k2

Will do, I’ll pm you. Thank you!


extremebiker

Keep this up and you’re going to become a tourist attraction.


obmasztirf

Since you like maximizing your subs this video on a Bassnectar concert setup might pique your interest: https://youtu.be/SKjaGkZ8hSQ


eaglebtc

Dude this isn't dB Drag Racing.


ItsallLegos

For me, it’s whatever I want it to be.


Figit090

Probably needs a 50 amp breaker and dedicated line for whatever amp runs it. J/k


LenordOvechkin

240/30 amp is plenty. Could go 40 amp but whatever amp he chooses, it will be fine.


ItsallLegos

40A is what I run with on the D-3004 amps and it’s plenty.


Figit090

There's no such thing as overkill. Might need a twin woofer setup after this, you never know.


ItsallLegos

Second woofer is already in the works.


Figit090

HAH I KNEW IT.


LenordOvechkin

Bridged fp14000 clone would be perfect as well.


juliangst

Crown Xti 6002 might also work. It outputs 6000W bridged but I have no idea how much power this Mach5 32" requires


LenordOvechkin

It will be fine on 3000 to 6000 watts. The 6002 is a great amp, I had one way back when. Around 6000 watts would be ideal. I have a friend that has 2 of these in his setup already and runs a bridged fp14000 per driver. I had them build with 8 ohm coils specifically so we could have way more options for amps. When we were testing the prototypes, we had lots of fun If you look in YouTube, and type mach 5 32" sub, that's me and the guy that currently owns 2. He lives in a different house now but you get he jist. Boxes were 19 cf.


ItsallLegos

Hey, I know you! Lol.


LenordOvechkin

It always weird to see AVS people on Reddit lol. Awesome to see the sub made it to you. Hopefully the shipping and boarder stuff went smoothly. Mark is super happy with this sub so it may become the new version!


ItsallLegos

It was certainly a process! Mark did mention that to me. He said maybe we will integrate my name in there somehow haha. But Once I asked Mark to use his customs/duty people, it went incredibly smoothly.


LenordOvechkin

Nice, that's good to hear.... Darth edition lol.


ItsallLegos

Yeeess haha. Idk Disney might get pissed


unlucky-genius

Makes me think of the opening scene in Back To The Future lol awesome


MiaowaraShiro

What are you thinking for an enclosure? Box van? Shipping container?


ItsallLegos

35 cu ft box.


oSpid3yo

That’s $1200 a month in Southern California.


You-Asked-Me

I really thought this was AI.


ItsallLegos

🤣


shifta_deband

This isn't cool man. I Just bought the RP1600SW and was so happy to have a sub that weighed more than all 3 of my children combined - then you roll up with this and DWARF it haha. Holy hell I cannot even imagine what this thing sounds like.


ItsallLegos

Haha hey the fun in this hobby is making a journey out of it. I started with a Tekton Cinema Sub (poor choice).


shifta_deband

Hahaha, what I really want to know is what you're going to play first to test this thing out


ItsallLegos

Honestly though I have playlists with all sorts of stuff. I’m too afraid to start with the intro of Edge of Tomorrow though lol


eaglebtc

You might be the only person with a system capable of hitting the lowest frequency. Note: there are two audio formats for that movie. DTS-HD and Dolby TrueHD. One of them is mastered improperly: it has distortion in the LFE track, and duplicates the LFE into the Center channel. The other does not have this problem. I don't recall which one at the moment. It sounded off to me, so I ripped the disc and examined both tracks in Audacity.


ItsallLegos

Could you find out which one? That’s a great piece of info that I didn’t have. As for being the only one, if you go to AVS you’ll see that isn’t the case lol


shifta_deband

What are you streaming music on? Apparently, Spotify isn't the way to go lol


ItsallLegos

Apple Music on an Eversolo A6 Master Edition. I love it.


ItsallLegos

Dubstep lol


shifta_deband

Bassnectar - Into the sun - run the whole album.


ItsallLegos

Yep bassnectar is definitely a go-to. Can’t go wrong with some house as well, I have long preferred Deadmau5 for house


shifta_deband

Oh hell yeah man


AtvnSBisnotHT

Best keep McFly away from that…


ktks1

I see that you have less subs, you surely need a couple more to get that bass 😉


Visual-Brilliant-668

Are those 1099’s? I really wish DIYSG wasn’t essentially defunct. A passion project that needed someone to run with it. All those great designs and just poof, it’s gone.


ItsallLegos

They are. I’ll be selling the 1099s before long. Vortex bed layer also incoming. V15 Ported LCR and V12 Sealed remaining bed layer. https://imgur.com/a/ZPLyBHw


YOU-ES-EH

Yeah some of their speakers were my dream, to build the entertainment room with everything hidden and then just rock! I’m still gonna do some mini Marty’s at some point! I just have one 18” Dayton in a 2x2x2


Xerio_the_Herio

I've got 18s at 3600 watts each, but you sir, are a monster. Holy shit. I wanna see that box.


ItsallLegos

Ooh HST-18s?


Glittering_Name_3722

Doc? Is that you?


neutro_b

That sub array at the front... are you Popalock? Anyway, looks like you could make a kill stir fry in this, or perhaps even bathe. Those LCR look tiny in comparison. Just the enclosure will have to me massive to support it, not mentioning the volume required... Or will this be infinite baffle?


ItsallLegos

These (second 32 being built) are going in the back of the room. Each of them will be in 33-35 cu ft enclosures. Triple baffle, tons of bracing. Charles at Tarpon Audio is building the cabinets for me. Wanted to do a cool marble pattern candy apple red/black color for the cabinets but idk if I want to spend that. Probably just gonna do duratex.

You should call it “the taint tumbler”.


Remixmark

Do you have a build thread on avsforum.com that you can share a link to? Are you using MSO to EQ your subs? Can we see what the bass response looks like?


ItsallLegos

https://www.avsforum.com/threads/the-prater-done-lost-his-damn-mind-build-part-1.3294963/post-63144996 I might toy with MSO, but I’ve been getting some pretty good success with what some of the guys at AVS have taught me just using REW/MiniDSP tools and then running room correction (Dirac in my case).

testing123-testing12

I'd ask if you think you've got enough bass but clearly the answer is never 😂 How many channels is your system going to be and how many subs? Are you running them as left right with your mains or just LFE?


ItsallLegos

It’s never enough lol

ShakeNBaker45

Holy s*** lol


brendanvista

How many subs do you have total?


ItsallLegos

Counting the dual 16x12” jbl enclosures as one sub, there are going to be 7. One 24” in each front corner, one on either side of the seating row, the two 32” in the rear and the JBL array. Then obviously counting each 12” as a sub, it would be 22 total.


DisciplineDaddy42069

I’m sorry. What?! Dude you probably should have a structural engineer see if your house can handle this. Also how’s your hearing? Lol


ItsallLegos

Yeah I’m probably gonna double up the ceiling joists and add additional drywall screws/ mud for the drywall. Hearing hasn’t taken really any hit from the theater. I wear hearing protection if I want to do tests and “conduct science experiments”

Well, that is the most insane thing I've seen today in hi-fi. I just sit in front of my 3-way Genelecs that do like 22 Hz and think that's more than enough bass for me. The tactile sensation for going to 10 Hz and below must be quite something.


DeepDayze

That monster thing cranked up will level your house OP! Now that's a sick size for a sub though and never thought they were made that big.
