Your welcome thanks for being a daily subscriber!
Thank you for sharing dear Jacob!
The frequencies are called sine waves also know as test tones. They usually come in 0db ( full scale ) -5db and -10db.
For this test of finding box tuning you can use -5db or -10db. 0db at too loud of volume could damage your sub. 0db is only for SPL competition.
Def keep your head unit or radio half to 2/3 volume. You would use -5db tones from 20-70 Hz for subs unless you know about what your box tuning is. Start at 20Hz and go up to 70Hz by 1Hz or 2Hz ( 20,21,22 or 20,22,24,26 )
If u think u know the tuning, Ex: builder says 33 Hz tuning on your ported box. Then test 30Hz - 38Hz -5db tones. You should be in the right range to find the tuning by the least movement of the sub if the box is built half decent lol.
Test tones are also used to set gains on Head units, Phones, ( source audio ) DSP’s & amplifiers.
Hope this helps anyone undertstand who may have missed something in the video.
I am just seeing some of your videos now in June 2022. I usually dont comment on videos I watch but I really wanted to take a second to say that your videos are very informative, and they are easy to understand what's going on, and most importantly why you are showing the tests and simulations you are, to me is just as important as the actual steps involved. Thank you for sharing your knowledge here.
Thanks Brian for watching! Glad to help where I can.
I thought we needed to figure this out to set subsonic filter. So how can we set it if we don't know what it's tuned to?
Fr like I need the frequency to set my subsonic😂
Yes, thank you. Now I actually understand what it means for a sub box to be "tuned" to a specific frequency - I would love to figure it out just by measuring, I bought a car with a sub in it, and the previous owner didn't have any idea about what wattage anything was or type of speaker - he said he just asked the sound guys to give him the best for a certain amount of money - I just ordered an oscilloscope, so as it's on its way I have to figure out what exactly type of speaker it is (it's a Digital Design that is all I know), no labels or markings on it whatsoever except 'DD' and a huge magnet with Digital Designs imprinted on it (it's a 10" speaker hole but the speaker is about 9" I'm not sure exactly) - so I'm going to remove the speaker again, take a bunch of pictures and measurements and send it to Digital Designs to see if I can get the specs for it. I am an audiophile who wants it to sound perfect, but thanks, I just came across your channel, I'll scope out the rest of your videos :-D Thankss
Nice little video, I'm still in a prefab and was curious what it was sitting at...thanks!
ive been wanting to find this out,thank you so much!
Gonna give this a shot tomorrow, wish I could’ve stumbled upon this vid years ago 👍
You Have one hell of a box vibration going
Some good info. I kinda new this before, but your video showed me the importance of doing this type of test. It gives you valuable tuning info. Thanks for valuable content
Your welcome 👍 got a good bit on playlist in my channel if needs learn more
I like bass mekanic test tones on a CD. Its always clear 26-28 seems to hit the loudest but I don't know. Thanks for teaching me something Jacob ill try to use your method to find the exact hz my box is tuned to.
Dude that's dope,I appreciate you making this video. I'm excited to find out if my box is actually tuned at 32. Thank you for all the content.
Your welcome and thanks for being a subscriber!
@@JacobViral2 I’m a little confused this portion is easy thanks ,,, curious about cabin transfer or cabin peak I use my meter for that to gain spl should I shoot to make cabin and tuning close or a little under my cabin peak seems to be 33 ,,, I’m doing 57.5 looking for 60 ..
@@schmidt76ful nice score! Optimal SPL results from people seem to be best when tuned near cabin
@@JacobViral2 thank u buddy
Not really into your stuff but this video really helped me find an app called sonic soooo thanks I guess, good luck with everything and everyone. BASS ON!!🔊🔊
The problem is not everyone but a lot of people don’t know anything about frequency Hz, clipping, and Soundsystem tuning so they don’t know anything so they just play heavy frequencies and a lot of times blow out the speakers and subwoofers and then some new that have custom built sound systems had a friend or a shop do it and they don’t know anything like I said, and end up doing the same thing with that as well blowing it up I’m not seeing everyone but a lot of people, especially those who just want heavy bass, and know nothing about it
good stuff. helped me find my frequency.
Heck yeah I finally learned something new thanks man
This was very helpful!
Love the video once you find the freq then what ? How do you set your amp or subsonic once you found the sweet spot
Half octave below tuning. Here’s a playlist th-cam.com/play/PLkYp1Fj-99b0pFNxaohIxCaer8VxQVZ2j.html&si=oCrLonWVEGvfwDpV on audio topics including tuning amp all parts
I think it would be cool if you went live on Facebook or something we could ask you questions one day
Could consider TH-cam live sometime :)
Is this to find your gain,LPF, or subsonic?
Tuning crossovers mainly and SPL test/port knowledge tuning
When you put your head/body into the port, don't you alter the tuning frequency of the box/port?
Since the tuning frequency is decided by the port area and length of the port?
Correct, anything that blocks or goes into the box/ port adjusts everything.
I just was thinking about this!! Thank you!
Go-Rilla Great info Jacob thank you!
Nice I learned something new.
One thing I didn't understand, low frequencies in all speakers forcing the woofer the move more back and forth as you go down. and med to high frequencies the woofer need less movement but much faster ones. that's why subs have bigger rubber diameter with slow bigger movement and tweeter are smaller and almost have non. so I don't understand how looking on the speaker can give any information. I did some testing my self and find that you can seat in front, play the frequencies and most lower audible frequency you hear is mostly the box tune frequency,
like if 30 is barley heard (not felt) and 40 is audible to your ears then it's probably 40 hz.
I’m gonna try this. I found a blueprint for a box and just had it built. I have no idea what my boxe is tune to Right now….But hopefully this will tell me my box tuning
I had no idea how to find what my sub box was tuned to…TY BRO! Subd…peace out..:)
Your welcome thanks for subscribing, more coming!
My sub continues to move between 18hz up to 100hz.
Ive tried different port lengths with no difference. At no point , does it stop moving or moves very little ,within this range. .
I have no idea of tuning frequency. Any advice ?
Plug-in to 12volt box calculator, shrink/open port area, new box, SPL db meter slope roll to loudest score(peak)
you really thought me something i did'nt know till now on how to get my real box tuned hertz
Glad to help 👍
You said make sure your subsonic is where it needs to be first but dont you have to know your enclosure tuning to know where to set the subsonic
You are correct. He is a little all over the place in this video, two much Red Bull or ??
What can you do with the info of knowing what your box is tuned to? Amp settings?
songs yo
That and from there you look up songs in that frequency (since you now know they sound the best with your setup)
Hi brother jacob, got a few questions.
(Side Note, Love my bass to hit lows that shake my soul and heart)
1. Do the Hz of a Subwoofer, lets say a sub is tuned at 25-500hz. Should I build a sub box (ported) and tune it to 25hz aswell to compliment the sub's 25hz or not? or should i tune it higher to 35hz-40hz. Because most prefab/custom sub boxes are tuned at 32hz to 36hz. But most sub hz be around 24-27hz. I don't get it.
Like kicker compr's dual 10. Box is tuned to 30hz but subs go lower then that and are about 27hz.
2. Is it a problem if I buy a amp to compliment my subs peak rms watts rating rather then the normal rms watts rating? Lets say i've got a kicker compr 12 the rms is 500watts and peak is 1000wats, most people say get a amp that is 500watts not 1000watts. But i personally want to get something in between, a 800watts amp would do. So is that a problem or not.
3. How should i make my enclosure and sub be the hardest hitting and also loudest that people can hear me from blocks away and also can play lows so well my heart and soul feels it.
Thats all bro
Usually sub can play half octave below box tuning. Tune any lower then 30hz means you won’t want sub to play loud above 40hz. Always best to get a sub amp rated 140-200% rms power to have play room and not max amp out. Tune mid 30s to play to 26-30hz range, tune higher will be louder but not as lows.
@@JacobViral2 thankyou very much brother👑💯
Yeah put more power on your Amp like he said, your not gonna turn the gain up 100% anyway or it'll sound like crap. I had 2 kicker compr 12s on a 1500w rms 3000w peak Amp for years and played em loud all the time never blew one
Hey there good tutorial, could you please send me the link to getting that exact app on your phone for testing thanks
Helpful video man cheers
will test my ported with this technique, interesting!
nice video, I will def try this out
Is tuning all based on the box? Or can bigger displacement subwoofers effect tuning? I recently bought a box (2 15s) that was custom built and is tuned at 32hz. So would that mean that any 15 inch subwoofer I put in the box still be at or around 32Hz?
Subwoofer affects tuning to for your peak frequency but box is tuned the same regardless of the sub just the sub changes your frequency variance.
The most effective method is to test for the impedance modulus.
For correct tuning.
Not for those awful sounding "Burp" efforts.
But a correctly tuned Helmholz
You will get an equal ripple reading of modulus.
Thanks
Are you moveing the subsonic all the way down when you have the test tone going
To find tuning yes just don’t unload or go full volume
Jacob you my dawg! Learn em something
Great info 👍
Frequency generator apps will be great for these types of test
What is this information used for? Now i understand how to find what my enclosure is tuned for. But can i now adjust my settings based of this information to improve my experience while using the sub?
Correct
Thank you for the video.. I appreciate this cause it helped me. I just have one off-topic question; why does your car interior look like the insides of a microwave oven? HAHAHA I love it!! Thanks again.
It’s been gutted from car audio walled systems and it helps get louder without panels
dude your like amazing I really look up to you keep the amazing work up🤟🤟🤟
You find the magic number on your box, What do you do with that information? does that correspond to the LPF setting on the amp
Know what songs that work well with tuning, SPL tests, setting amp lpf/subsonic, learning sub limits.
Bro! 🤯 ! Sick trick dude
I'm just now getting back into subs and amps as an adult and I have never seen that type of box can you explain why it's like that please I'm curious to know what benefit it is to have the sub inside the outer box like this? I kinda like it..
Next the subsonic adjustment what do you do if you have a ported box but the amp doesn't have the adjustment for it?
The Kicker cxa 1200.1 is the amp I have and am talking about.
Hope to hear back from you thanks.....
His box is a bandpass of some sort, they combine multiple types and/or sizes of enclosure and their characteristics.
Do I try this sealed or 1 window down?
I would do it where you like to SPL meter test or most often used. I like to do window down driver only
So 35hz is the max on my subsonic filter. Just leave it at 35 then do these test, and move the filter where the woofer is not moving/ bottoming out? Thank you for the video shit confusing me.
Yes, but weird for a monoblock amp to not go lower than 35hz, maybe be best off/down then.
How to do this with avr at home?
What volume should i set my master volume?
My sub amp is already set properly
But i don't know what master volume should i use?
Probably 60-75% volume
@@JacobViral2 0 is maximum volume
So is -28 good enough?
I found out the tuning if my box but which setting on my amp do I adjust so I get that tuning?
Subsonic, explained: th-cam.com/video/mfunR30oJHQ/w-d-xo.html
Cool dude, good vid
Thanks Man! Also what apps do you use to play songs? Also is there a decibel app?? How can i find out how hard i hit ?????
You need a DB meter for that. There are apps that analyze levels no very accurately just for finding peaks. But they won't be accurate if you're trying to measure a 145db system full tilt.
Would this method work for a tube enclosure pioneer ts-wx304t
It can work for anything long as you can see the sub yes
So first I find the loudest my door speakers can go before distortion with no gain and lpf then tune the amp setting the gain and lpf with the music volume still 75% (just before distortion) and then i can turn it down to like 50% then do the tone test till the sub moves less to find the box tune then set ssf half octave down ? Would that be the correct step by step method ?
@@2HUNNIDN98 Yep, seems complicated but it's not so bad.
Thanks bro 💯
Sup from New Zealand 🇳🇿 btw
so lets say we now know what the sub is tuned to. whats the benefit of that? what would i do once finding that out?
SPL peak frequency burp tests, optimal output from music around the freq, settings for amp crossovers, bandwidth limits.
If a box is tuned to 40hz but the low pass filter on an amp only goes down to 80hz (sundown sfb2000d) will it still be able to get close to the 40hz? Or will it be limited cause of the amp? I’m ready to switch it out for another one
LPF is the top end cutoff point so 80hz is fine, your talking about subsonic.
Love it thanks bro 👍👍👍👍👍
Your welcome 👍
Hey bro keep up the good works
Hey what’s up. Wouldn’t it be more correct if the subsonic knob was turned all the way down??
Then there would be minimal subwoofer output.
@@JacobViral2 okay. Got it
Still complicated to me bro I' need you tosending my measures for my 3 cvr 12s kicker 4ohms want to have them in a 4 hole ported box tuned lowest they go on an 1800 audiopipe anyway keep up the good video work
What do I set my subsonic at on the amp when I am testing this, all the way down?
I would do all the way down yes and just don’t go full volume
Can your box it the 4 th bass not on young jezzy Put on song that is at 28hz?
I have played it before yes
thank you so much
We're you get the sound from
Does that mean your bass will be the loudest at your tuned frequency?
Yes usually near peak tuning or peak resonance of the cabin of vehicle.
I’m kinda new at this. But wouldn’t your phone and your arm and everything else that you’re putting in the box to film it throw off the tuning by taking up space?
Slightly yes correct
I have a question, I need to know my box tune specs so I can tune the subsonic. But it sounds like the subsonic needs to be set correctly in order to find the right box tune. So how do I do one without the other
Start with subsonic or and find your tuning that way then adjust subsonic from my other video on how to do that.
🤔 so when woofer don't flex alot thats the final hz box tuning??? 🤷♂️ isnt it tha sign wave that does that... the higher hz tha less the woofer gonna flex right?
So after finding out what's my peak can I tune my amp with that hz test tone? Say my peaks 34hz do I use a 34hz test tone to retune or do I stick with 40? Also would I change the subsonic lv?
I have videos on setting each setting on the amp to watch but in general I would tune based from the tunings for the results yes.
@@JacobViral2so was you telling him to play a test tone of the 34hz? cause my speaker plays 30hz but you know they say play an 40hz test tone to set. So which test tone should I use?? 30 or 40?
very helpful videos
my wife would kill me tho if i rolled around with my car looking like a carpentry shop, ive had to make my install stealth in the minivan, you can barely tell there are two 12s, or any wires in car all over...clean. when shes in car, i usually just turn the subs off and run highs/or run subs at low power via gain knob up front under dash, about 19 volts...barely pushing 200 watts...when hes not in, i crank them up near full power...tho two type rs @ 2ohm pound hard at 42 volts or near 900 watts lol
Thanks and yea it’s a project Explorer gutted from multiple walled systems. More videos coming daily stay tuned. 👍
Question is... Do you use this freq. Or is there another way to find out which freq. Is best for your car at termlab numbers?
An decibel app for best output and tuning as well but overall this is how I did.
So thats a 4th order or just a ported box? Looked sealed and ported like a 4th
this was a 4th order bandpass
Whats the app you using for the test tones on the iPhone?
Could use car audio app tone generator. I just have downloaded a list of tones and sweeps from a usb I bought long ago.
Jacob Viral2 Okay thanks cause I was told by box is tuned to 34hz sometimes I wish I would have told them 32hz but they said that’s low in the dirt for regular music
30 hz is my favorite tone
I think it's funny on your other channel when you ask them what's it tune to and they don't know but they have a lot invested in there system
A lot just plug and play and not go into specs donuts normal for a lot I understand their point but still yea
What if you don't have your gain set or subsonic, how would I do it then?
Turn subsonic all the way down and adjust gain to preout voltage of rcas eyeballed then do half to 3/4 volume to see.!
@@JacobViral2 thanks
Anyone know a.good app to use to find box tuning and spl.
Can you send me the specs on how you build your box
Sealed spec 1-1.2 cubes net, ported the rest to what for in the space needed. port area 60% cone area most do.
So once I have found the box frequency do i set my subwoofer lpf as close as possible to the box frequency?
Check my recent video for how to set lpf
He said the lpf should double the box frequency. So if 33hz then lpf should be 66hz
That not necessarily true about the point being when the speaker moves the less. I've seen/had speakers that start moving at volume 26 with a 40hz tone playing and doesn't clip until volume 35, speakers moving aggressively.
Thankyou for this
Your welcome thanks for watching and subscribing!
@@JacobViral2 maybe you can help, I have a alpine type r system and front component speaker in door is doing a little static crackling sound on certain songs at a reasonable high volume , what would cause that in your opinion ?
I have swapped rca input on amp from left to right to rule out amp/ wiring etc and still same left speaker only makes this sound
Sounds like a blown or soon blown speaker or a ground issue.
@@JacobViral2 mmm hope its not the voice coil but I doubt its a ground issue as every thing is correctly wired , thanks for replying mate its much appreciated
Thing is if i need to know my box tune in order to set my subsonic?
Yep explained: th-cam.com/video/mfunR30oJHQ/w-d-xo.html
Very cool video!!🤛🤛🥋
Thanks Don!
I’m confused man, I thought in order to set your subsonic filter you need to know what your box is tuned to... I thought you had to put your subsonic all the way down and then do this test
You are correct. He is a little all over the place in this video
@@SynergyAVE alright thanks for confirming , so I’m not completely stupid then lol
Yeah it has to be turned down all the way because the person that customized the box didn’t have a subsonic option while they were making it. Makes sense to me
Awesome fkn video ....but ultimate car audio is the best to do box building
Great idea of an app for tone generator
Just to verify..
Keep bass boost off amp always?
Everybody I ask says always leave bass boost off on a amp.
Have you ever used it?
correct I never use it for Agee reasons showed in my video.
Awesowe video, keep it up. Sty cnnted :)
So the tuned enclosure isnt loudest at the tuning frequency?
usually near that if built right but the peak resonance of the car can affect it also.
@@JacobViral2 i have an idea. My buddy has a tiny dog and a 4th order box. We can put the dog in the port and burp it at different frequencies and see how the dog reacts. If it comes out of the box right away then Im guessing the frequency it close to tune?
The 🐐
How can you set a sub sonic if you don't know box tune
mid-volume tests with subsonic off, then set subsonic after finding tuning.
You could set up camp inside that subwoofer box lmao You can just use a frequency app. Play any frequency you want.
How many db's is this setup?
This single sub 10” build hit a 148db+ on glass at 46hz
Does subsonic on make your bass hit harder ? I have a box with port centered and tuned to 35hz , what should I level my subsonic to ? Please let me know @jacob or someone
jon doe : I have my subsonic all the way off - some songs hit hard but other songs don’t hit as hard - should I turn up the subsonic ?
jon doe : someone told me that it’s good to keep the subsonic off
jon doe : what do you mean by every music play ? Do I have to set the subsonic to different beats ?
You're thinking of it backwards.
All a subsonic will do is REDUCE power below a certain point at a cert slope.
If you set an ssf to 35 hz it will gradually lower the input level the farther down you go.
If your subsonic is set to 40hz and your box is tuned to 32. That means that by the time the frequency gets to 30hz the ssf robbed the wave of a significant amount of energy. And you won't be playing as loud as you can at port tune.
In that instance adjusting the ssf to a lower frequency WOULD make you hit harder.
but only in that specific instance and similar ones.
Id you have ssf off. You wont get louder by turning it on.
Except for some really isolated, rare and coincidential situations.
(Songs with 23hz notes and notes in the high 30's playing together. The sub can't play two notes at the same time very well, so if a subsonic is reducing the volume of the lower note the higher note will get louder).
But it's extremely rare that music contains that kind of structure.
jon doe : I don’t play rebassed music , I just play music straight from iTunes with aux connected. Some songs hit hard and some don’t - I have SSF off , should I turn it up a lil ? Maybe 25hz which is half way or less then that ? Am I doing something wrong ?
Why does the sub move less at the tuning frequency?
It's due to the positive & negative pressure loading against the woofer, here's a link to a simple explanation from Barevids. th-cam.com/video/BnHaodRowgc/w-d-xo.html
Is say 34hz preferred over 42hz ? Does it matter if the tune is higher or lower?
Depends on your musical range you want and if SPL or demo
is this way really accurate?? by placing your hand inside to film the speaker movement.. you've already decreased the size of your port hole size with your body. that probably affected the tuning frequency..no??
Concept yes works great, your point is correct though probably throws it off 1-2freq
Can somebody please explain the (order) of speakers or box whatever it is ??
4th order here is just a sealed box inside a ported box
NICE BRO!!!
