I've learnt more watching your subwoofer builds than from all other sources combined about sound design in general but low end speaker design especially.

@BenHeien they were meant for DJ and live sound and have lots of output but don't go super low. Though low enough for most of my music. I could probably block off ports to get them lower though I'd have less sensitivity at the bottom end but could turn them up more.
This man literally makes some of the best explained audio videos. Keep em coming! Edit: Man my Sennheiser Headphones friggin LOVE this demo. They were shaking my ear drums fluidly. I wish i could have you make one of these for my house. I could hear all the way down. every note.
Normally I'd scoff at a sealed box but considering how much larger the driver and box are im sure it plays lower than the old sub did. Also good idea building in the brace to help stop standing waves in the box. That's something I never thought about doing.

Excellent video. The production quality is top notch. The editing and voice over gets your points across very well. You obviously spend a lot of time on these videos. 👍
As a DIY guy at heart I love your channel. The first several pairs of speakers that I made back in the 70s used Philips and KEF drivers. I wish I had the tech that is available now. It was largely trial and error back then. I listened to this for the first time through a pair of $39 mint green Skull Candy in-ear buds that responded reasonably flat down to the 16Hz note. The audio on RUclips can be surprisingly good! As a side note, I enjoy listening to different loudspeakers in reviews when they are recorded under very controlled conditions in the same space with well placed high quality microphones. These reviews when heard through good headphones or home speakers can easily reveal differences between the different models. Yes, it is true that we are not listening directly to those speakers and we will not be able to detect things like their ability to reproduce depth or soundstage but useful differences in tonal balance and frequency response can be heard. It is boring listening to the "purists" who dismiss these types of comparisons out of principle. Just thought I'd share this because you seem like the kind of person who might have thought about this at some time.
i love soph's reaction to hearing the sub for the first time, i know that feeling well after building a system and it actually turns out the way i had hoped lol. sometimes my customers pick bad equipment and the results are poor to say the least. im always after the crazy low end response, but i also listen to a lot of music from the 80s, so my drivers need to basically do everything. doesnt usually work that way for me though, but after seeing this i am def leaning towards going sealed again! along with some ideas for cutting down on the waves inside, never heard of the "line of sight" method before and i really like that.
I was not ready for the 16Hz hit, only had the SVS PC-4000 hooked up for half a day and it's expressing things I did not know were there before with my random powered home theater sub that the amp died in and I converted to a passive sub powered by a crown XLS 1502 in bridge mode. Also surprised that RUclips compression/encoding did not eat that.

I have one of those in a 6.4 cubic foot box tuned to 15 hz. I added a 5 db boost at 20 hz and in room response is flat down to 12 hz. Too bad they don't make these anymore. I think I bought the last one at PE.
Was i the only person dissapointed to not get to hear the pleasure of this build? ahhhhhh now i gotta wait for the next one. Man this is going to be good!!!
I guarantee most people gear in the comments can't get that low. They think their cheap 6.5" drivers or cheap headphones can play that 16hz when they hear the harmonic distortion that is much louder than the actual 16hz tone when those drivers are trying to play it. Alternatively they listen very quietly but I doubt they would hear 20hz then.
Using my senheiser momentum 4s and I'm always blown away with how well they keep up with those lows for Bluetooth Headphones, I'm surprised I didn't hear any rattling with that 16hz tone lol I'm assuming you spent some time eliminating any other noises, sounds immaculate👌 Edit: *feels immaculate
I'm listening though a DSP corrected setup with a Benchmark DAC HGC, Acoustic Research ar2000 monitors, and a custom built "golden ratio" subwoofer enclosure made from dual sandwiched 1" MDF with a 15" reference series from Dayton audio, so I'm probably pretty biased about this... But I heard all the notes at equal loudness except the last one was just a small bit quieter!
I would love to see u in others platforms (preferably in one that you are giving an course about designing a box using all the software's that you use 😁)
10:54 i like the apparent loudness, as that is what i tune my system with and get best results from. and for my speakers it sounded like 20 to 30hz was lowest in amplitude and 16 and 18hz was much louder. especially 16hz was loudest, that is an impressive frequency. my hypothesis is that apparent loudness gets magnifies when recorded and played back on a apparent loudness eq'ed system, but sound perfect for the original system.
I'm so sick of RUclips and the three corporations that own all of human culture pretending fair use doesn't exist, they all need to get sued. Anyway underrated channel for sure, I'm travelling and and you're making me miss my $75 Lanzig 3000 Watt Amazon special and Craigslist ported twin 2 ohm 10s. Bluetooth dongle in an old 45 what Sony deck was involved you'd probably be disgusted
Had to crank up the home theater system for the end of this one. It’s a small one for now. The main one is still in storage. The little sub was still trying to reproduce the 16Hz but was so low I could barely hear anything. Same with the 18Hz. With that said, I’m impressed that such a small sub was doing anything. Vizio M512A-H6 it’s a few years old at this point.
I have a complete Infinity speaker and sub system and the 16hz was audible. However this system is a near field setup, my sub(12") is literally under my desk and everything sounded amazing to my ears!
My headphones registered down to 18hz - nice work! I make subs for musical instruments (flat to 20hz) - kudos to you for bringing your studio in on the fun!
11:15 my Headphones are doing great, this hammering sound, I would like to experience that in Person :D And for the Demo Videos... Maybe put the Demo files on a decentralized Storage like IPFS (be sure, to keep it pinned to your node that you host...) But I would certainly pin it too, since that's impressive.
And to add to this: Headphones are the Moondrop Blessing 2 Headphone Amp is a quite "cheap" one in comparison, but the Fiio BTR5 serves me well over USB.
11:24 - Quite impressed with the response of the SteelSeries Arctis Nova Pro Wireless. it did quite good with your frequency tests at the end of the video. wouldn't call it perfection but for a "gaming" and wireless focused product it did a pretty good job.
I'm curious. Did you consider an infinite baffle subwoofer, or was cutting a hole in the house not an option? I ask because I have been reading up on them, and have the ability to cut holes in my house now I own one!

I built my IB about 10-15yrs ago. Quad 18" attic mounted manifold, w/IB3-18" from Fi. Learn as much as possible beforehand, since the positioning can't be easily altered.
First listen on WF-1000XM5, and no, not keeping up in the equal loudness stakes, but I am weirded out that they even DID the 16Hz. Or that I could hear it. Unless, the driver is rumbling?
Ok, slightly impressed with the Sonys, XM4 overear basically the same - flat-ish to the note before 20hz, then dropping off. Still doing 18 and 16hz though. Much lower, yes, but that they even do it is cool.
Would love to see you stay on RUclips - I have no ball in play with regards to what music to demo, so for me, feel free to go ahead with your own music :)
Steelseries Arctis Nova 7 headphones. I personally can not hear that low (age and hearing damage), however, I could still feel the vibration from the lowest tones you played in the headphones.
Fun test. My hd280's kept up with my phone but not my macbook, did not grab a headphone amp. HD555's and a mass drop open element variant PC38 did not keep up as well as the hd280 pros
I would like to see you Build a Small Stand Mount Transmission Line Speaker. USING the "Speaker Stand as 2/3's" of the Length of the Transmission Line.
Big up on the acoustic Elegance choice! Been a huge fan of theirs for many a year for many critical applications in live sound and other more novel builds. Still Loving your videos try pushing your boundaries a little further my friend always looking forward to your content. cheers
Yes, Beyerdynamic DT 880 Pro can keep up... Very nice sub! Have some big drivers laying around here. Perhaps I should build a big box around one of them and have some fun...
When I turned the volume up on my Coral BX-1000 speakers @18hz (but not @20hz) your voice was experiencing a sorta reverb effect. These old speakers keep surprising me. But they did play the 18-20hz tones but not to where they would be heard or felt over higher frequencies. I enjoyed your demos. Truly original music.
I can hear it on my ATH m40x headphones down to 40hz. I have them very gently EQ'd. Under 40hz, I hear nothing until 20, 18 and 16hz. At those frequencies, I can hear my headphone drivers fluttering, but not distorting. Listening with a Schiit Heretic headphone amp.
The equal loudness demo is impressive. I dont know if I have heard a system that didnt have a frequency jump out or flutter when playing 40hz-160hz, let alone 18hz! KZ ZS10Pro''s played the 16hz, too!
Once again im not disappointed with my Beyerdynamic DT770Pro, which covered ever note you played at the end. Tbh, at frequencies below 30Hz its more like a vibrating sensation than an actual audible sound, but nonetheless, it works!
I am ABSOLUTELY a shill for sealed enclosures. My very first system ever was a full kicker speaker/sub combo in my 1993 del sol (as i called it, the del slow). I had typical cheap kicker speakers (the black and yellow low end coaxial) in both doors and rear pillars. and then I had a 12" kicker comp sub, from way back in 2008/2009 (black and yellow). The amp I had at the time, I didn't know it but turned out for the price it was actually super strong.... it was a crunch dual channel which I had wired the sub into bridged. and apparently, according to some reviews of the little thing, it can output 300w when bridged which for me, at that time, was insane power levels. and i used the bass boost which made it thump that much harder. anyway it was a sealed system. and i let it run up to 250hz because the sub was rated to 250hz (I remember it being that way and chose that for the 12db cutoff on the headunit). after this I had a 2006 honda s2000. jbl speakers (yuk) which i got rid of and put in a pair of polk audio mm series. then I had kept the 12" kicker sub until it blew up.... sad days. then I had traded the s2k in for a 05 subaru wrx sti.... i had a couple systems. one was a custom transmission line box I made. first with a cheap sub (dont even remember the brand) but then I had put in a pioneer sub (hated). the port noise was horrific. figured "I made it, user error" so I bought a cerwin vega dual 10" box for stupid cheap from the car audio shop behind my mechanic shop. barely running 300 watts the subs blew.... but that whole time, nothing but port noise. could argue user error, but I replaced the subs with another set of 10" brand new with the same 300w and it still had insane port noise. finally went back to sealed and had pure sound quality. i get it, ported hits really low, but that port noise, for someone like me, im too sensitive to it. i like my music loud but also crystal clear. and the only way to achieve that is sealed.
I love your videos. My preference would be to continue to use your own music (which I like) so that we can continue to easily access your videos on RUclips. ☮
I've got Truthear zero's (iem with subwoofers) And they go all the way down to beyond human hearing, 16hz was very interesting to hear, it was basically silent but I could feel it just fine, now I want to get a bass exciter for my chair, dammit
Beyond human hearing is simply the point where your ears start to roll off which varies person to person. 20Hz being the common accepted frequency where most peoples ears roll off. But it's not a brick wall and you can hear below that just fine. Normally you just need some extra output as you go lower to hear it at equal loudness vs higher frequencies. If your hearing cuts off at 15kHz for example. As in, you can hear 14kHz but can't hear 15kHz at the same volume. Bump up 15kHz by 6dB-12dB and you'll find that you can hear it. Heck give enough volume to 20kHz and you'll hear that too even if you can't hear 15kHz at normal levels.
@@JoshM7 The zeros subwoofer can produce frequencies all the way down to 3hz, you're telling me that 3 hz is audible when you turn the volume up? Yeah, but you're eardrums and subwoofers will be in agony with the amount of excursion the subwoofers will be doing to make it equal in volume to music at a good listening volume
@@mr_bear6362 yeah 3Hz is probably going to need a crap ton of gain to hear it. It would sound more like the background noise is pulsing vs hearing a actual tone but I personally still call that hearing it because if you plug your ears you won't hear that pulsing sense anymore. It'll sound like a tremolo effect with your ears with loud frequency around 10Hz or 11/12Hz and below. Assuming you aren't using headphones and using a sub/subs. I've not tried it with headphones because most have too much harmonic distortion to actually play loud enough (110dB minimal preferably more) at 10Hz area.
@@JoshM7 I see, you're dying on the hill that (almost) any frequency is audible if you turn it up enough, that's true. Counterpoint: You could have just said that instead of typing 4 paragraphs of technicalities
11:16: ATH-M50-BT2 bailed around 30Hz. Also, heard Floatplane works pretty well for music, especially real-time streams, due to a different compression algorithms, but will require a monthly fee for your subscribers (which you will be mostly collecting yourself) to be able to watch anything there.
When the tones were played @ the end, were we hearing them from your sub using a microphone, or line out from your keyboard? My sub is audible to 20hz, but could see the cone oscillating @ 16hz. Nice build.
My custom he4x in 3d printed port feed folded cans. Stall hard at 14hz. But they took 5mo and a custom ai model with over 40 million iterations in simulation and over a dozen sls prints to achieve the ±1.2db response from 18hz to 18khz
@icarusix8750 nope, I build ai models, and I'm a hardware engineer by day and a mix of spl and sq audio nut by night. I have an spl demo box (2006 scion xb with a 6th order wall tuned for 24-55hz running 6x sundown ns v6 18's on a 3 of d4s jp73's in the doors is a 4way setup with 10"' 6.5" super tweeters and horns. Each door has a pair of jp234's A massive dsp is used to do time alignment and respond tuning. In my bedroom is a semi pro dj system mix of jbl and ev gear with crown amps. And 2 fog machines, 4x cold spark machines 12 par lights 8x 4ft wall washes 12x 6w lasers 6x moving head 230w spots 4x beams 300w, 2x derby lights 4x beam bars Everything is dmx controlled, and I build custom lighting tracks using custom software to sync the light to movies. I have OCD and when something gets my attention I tend to take things to far
Great choice on the sub, I ran stryke way back and theyve only gotten better since the name change/rebrand. Would be cool to see you do something in car with one. As far as other platforms go maybe floatplane would be a good place for some stuff. Audio based collab with ltt might be interesting. Im using a single 18" sealed in my home studio as well. Similar box design as well with similar bracing for the same standing wave issue. Really like those corners might have to come up with my own version.
I'd be interested to know how the initial equal loudness curve was generated. Was purely based on Fletcher-Munson curves or those plus measured room response at the normal listening position? I'd have to guess at the latter as some DSP corrections are then applied. But then I'd have to ask which F-M curve was used, as the tonal corrections vary with SPL. As always, the platinum standard to which all other speaker building videos are compared!
I was watching on my iPad and of course all I got was 80hz and above. Switched to my JBL Endurance Peak 3’s and sure enough there was some bass (duh), but surprisingly while rated to 20hz, the 16hz was just as audible. Now if I could just get my truck to do that!
Good to see a new upload from HexiBass! I like the build and lots to learn in this one. Some other audio channels have a second channel for the audio demos to run on...that are no monetized.
Rumble side channel. My cheap and 15 yr old home theater setup heard 40hz just fine but everything tapered off after that... but I had my sub turned off and that was just the 6" drivers in the home theater speakers. I could detect all the frequencies down to the lowest but at minimal amplitude. Your work and videos are always top notch. You just showed me something I don't need but really want now lol
Excellent video production quality! However, I think it should be noted that a low Fs sub driver should only be a priority when not utilizing equalization and/or using low-voltage amps. Higher effective motor torque improves impulse response and a stiffer suspension lowers the box size, with very similar SPL at the Fs of a low BL/soft suspension driver.
Regular 2.1 setup didnt keep up with anything below 30Hz but my Beyerdynamic DT770 headphones through the SPL Crimson didnt disappoint :) massive sub you got there :D definately envious!
I been looking for your channel for weeks, 3d print a back for the ROG Ally X to make it sound better? I noticed after playing with APO equalizer and hesuvi the sound was amazingly not bad, but needs some tweaking like a custom tune profile. Who 3d print's small speakers and tunes them? You! I think this is as much in your wheel house as possible. I can't convince you to do it but I thought of you instantly when the idea popped in my head so just thought I would put it out there.
No compromises on the Hexibase channel clearly
I love the "How it's Made" feeling from this video!

Using my senheiser momentum 4s and I'm always blown away with how well they keep up with those lows for Bluetooth Headphones, I'm surprised I didn't hear any rattling with that 16hz tone lol I'm assuming you spent some time eliminating any other noises, sounds immaculate👌
Edit: *feels immaculate
You are not hearing 16hz in any way.
@LingLing1337 no I can't, but I can feel the pressure of the diaphragm moving back and forth in and around my ears
I'm listening though a DSP corrected setup with a Benchmark DAC HGC, Acoustic Research ar2000 monitors, and a custom built "golden ratio" subwoofer enclosure made from dual sandwiched 1" MDF with a 15" reference series from Dayton audio, so I'm probably pretty biased about this... But I heard all the notes at equal loudness except the last one was just a small bit quieter!
I would love to see u in others platforms (preferably in one that you are giving an course about designing a box using all the software's that you use 😁)
Cool Sub! I think the huge cone with the PA style surround should make a lot of fast, precise bass. Have fun!
10:54 i like the apparent loudness, as that is what i tune my system with and get best results from.
and for my speakers it sounded like 20 to 30hz was lowest in amplitude and 16 and 18hz was much louder. especially 16hz was loudest, that is an impressive frequency.
my hypothesis is that apparent loudness gets magnifies when recorded and played back on a apparent loudness eq'ed system, but sound perfect for the original system.
dude this sub looks priceless
I'm so sick of RUclips and the three corporations that own all of human culture pretending fair use doesn't exist, they all need to get sued.
Anyway underrated channel for sure, I'm travelling and and you're making me miss my $75 Lanzig 3000 Watt Amazon special and Craigslist ported twin 2 ohm 10s. Bluetooth dongle in an old 45 what Sony deck was involved you'd probably be disgusted
Had to crank up the home theater system for the end of this one. It’s a small one for now. The main one is still in storage. The little sub was still trying to reproduce the 16Hz but was so low I could barely hear anything. Same with the 18Hz. With that said, I’m impressed that such a small sub was doing anything. Vizio M512A-H6 it’s a few years old at this point.
I have a complete Infinity speaker and sub system and the 16hz was audible. However this system is a near field setup, my sub(12") is literally under my desk and everything sounded amazing to my ears!
My headphones registered down to 18hz - nice work!
I make subs for musical instruments (flat to 20hz) - kudos to you for bringing your studio in on the fun!
11:15 my Headphones are doing great, this hammering sound, I would like to experience that in Person :D
And for the Demo Videos... Maybe put the Demo files on a decentralized Storage like IPFS (be sure, to keep it pinned to your node that you host...)
But I would certainly pin it too, since that's impressive.
And to add to this: Headphones are the Moondrop Blessing 2
Headphone Amp is a quite "cheap" one in comparison, but the Fiio BTR5 serves me well over USB.
11:24 - Quite impressed with the response of the SteelSeries Arctis Nova Pro Wireless. it did quite good with your frequency tests at the end of the video. wouldn't call it perfection but for a "gaming" and wireless focused product it did a pretty good job.
I'm curious. Did you consider an infinite baffle subwoofer, or was cutting a hole in the house not an option?
I ask because I have been reading up on them, and have the ability to cut holes in my house now I own one!

I have 2 15 inch in my room with very well box tune on low frequency. I'm just to say that 15HZ just like high pressure with slow movement in my ears.
chiming in with a set of vintage AKG 340s. i could feel the drivers moving at 16hz
First listen on WF-1000XM5, and no, not keeping up in the equal loudness stakes, but I am weirded out that they even DID the 16Hz. Or that I could hear it. Unless, the driver is rumbling?
Ok, slightly impressed with the Sonys, XM4 overear basically the same - flat-ish to the note before 20hz, then dropping off. Still doing 18 and 16hz though. Much lower, yes, but that they even do it is cool.
Would love to see you stay on RUclips - I have no ball in play with regards to what music to demo, so for me, feel free to go ahead with your own music :)
Steelseries Arctis Nova 7 headphones. I personally can not hear that low (age and hearing damage), however, I could still feel the vibration from the lowest tones you played in the headphones.
Fun test. My hd280's kept up with my phone but not my macbook, did not grab a headphone amp. HD555's and a mass drop open element variant PC38 did not keep up as well as the hd280 pros
I would like to see you Build a Small Stand Mount Transmission Line Speaker.

Big up on the acoustic Elegance choice! Been a huge fan of theirs for many a year for many critical applications in live sound and other more novel builds. Still Loving your videos try pushing your boundaries a little further my friend always looking forward to your content.
cheers
Surprisingly the Jabra Elite 75ts kept up, I usually just use these for phone calls 😂
They did not “keep up”.
@@LingLing1337 oh perhaps I imagined the lower test tones then, my mistake 🙄
Yes, Beyerdynamic DT 880 Pro can keep up...
Very nice sub! Have some big drivers laying around here. Perhaps I should build a big box around one of them and have some fun...
you could put the braces at inequal lengths from the sides to break up harmonics more.
When I turned the volume up on my Coral BX-1000 speakers @18hz (but not @20hz) your voice was experiencing a sorta reverb effect. These old speakers keep surprising me. But they did play the 18-20hz tones but not to where they would be heard or felt over higher frequencies. I enjoyed your demos. Truly original music.
Bull.
I can hear it on my ATH m40x headphones down to 40hz. I have them very gently EQ'd. Under 40hz, I hear nothing until 20, 18 and 16hz. At those frequencies, I can hear my headphone drivers fluttering, but not distorting. Listening with a Schiit Heretic headphone amp.
me i got the m50x it goes down to 15hz tbh
The equal loudness demo is impressive. I dont know if I have heard a system that didnt have a frequency jump out or flutter when playing 40hz-160hz, let alone 18hz! KZ ZS10Pro''s played the 16hz, too!
Demos can be split between the visual on You Tube, with sound, and something like SoundCloud for just music.
Thank you. Today I learned that there was a term for what I used to call a subwoofer going to sh*t: Modal Breakup
Once again im not disappointed with my Beyerdynamic DT770Pro, which covered ever note you played at the end.
Tbh, at frequencies below 30Hz its more like a vibrating sensation than an actual audible sound, but nonetheless, it works!
I am ABSOLUTELY a shill for sealed enclosures.
My very first system ever was a full kicker speaker/sub combo in my 1993 del sol (as i called it, the del slow). I had typical cheap kicker speakers (the black and yellow low end coaxial) in both doors and rear pillars. and then I had a 12" kicker comp sub, from way back in 2008/2009 (black and yellow). The amp I had at the time, I didn't know it but turned out for the price it was actually super strong.... it was a crunch dual channel which I had wired the sub into bridged. and apparently, according to some reviews of the little thing, it can output 300w when bridged which for me, at that time, was insane power levels. and i used the bass boost which made it thump that much harder. anyway it was a sealed system. and i let it run up to 250hz because the sub was rated to 250hz (I remember it being that way and chose that for the 12db cutoff on the headunit).
after this I had a 2006 honda s2000. jbl speakers (yuk) which i got rid of and put in a pair of polk audio mm series. then I had kept the 12" kicker sub until it blew up.... sad days.
then I had traded the s2k in for a 05 subaru wrx sti.... i had a couple systems. one was a custom transmission line box I made. first with a cheap sub (dont even remember the brand) but then I had put in a pioneer sub (hated). the port noise was horrific. figured "I made it, user error" so I bought a cerwin vega dual 10" box for stupid cheap from the car audio shop behind my mechanic shop. barely running 300 watts the subs blew.... but that whole time, nothing but port noise. could argue user error, but I replaced the subs with another set of 10" brand new with the same 300w and it still had insane port noise.
finally went back to sealed and had pure sound quality. i get it, ported hits really low, but that port noise, for someone like me, im too sensitive to it. i like my music loud but also crystal clear. and the only way to achieve that is sealed.
I laughed entirely too hard when you started talking about latency... The struggle is real...
I love your videos. My preference would be to continue to use your own music (which I like) so that we can continue to easily access your videos on RUclips. ☮
I didn't hear the 16Hz but I felt it.
I'm using headphones and can clearly hear it.
@@wendohgermaine6448 Then you're experiencing distortion.
@@wendohgermaine6448 me my dual 18 inch subwoofer
I've got Truthear zero's (iem with subwoofers)
And they go all the way down to beyond human hearing, 16hz was very interesting to hear, it was basically silent but I could feel it just fine, now I want to get a bass exciter for my chair, dammit
Beyond human hearing is simply the point where your ears start to roll off which varies person to person. 20Hz being the common accepted frequency where most peoples ears roll off. But it's not a brick wall and you can hear below that just fine. Normally you just need some extra output as you go lower to hear it at equal loudness vs higher frequencies.
If your hearing cuts off at 15kHz for example. As in, you can hear 14kHz but can't hear 15kHz at the same volume. Bump up 15kHz by 6dB-12dB and you'll find that you can hear it. Heck give enough volume to 20kHz and you'll hear that too even if you can't hear 15kHz at normal levels.
@@JoshM7 The zeros subwoofer can produce frequencies all the way down to 3hz, you're telling me that 3 hz is audible when you turn the volume up? Yeah, but you're eardrums and subwoofers will be in agony with the amount of excursion the subwoofers will be doing to make it equal in volume to music at a good listening volume
@@mr_bear6362 yeah 3Hz is probably going to need a crap ton of gain to hear it. It would sound more like the background noise is pulsing vs hearing a actual tone but I personally still call that hearing it because if you plug your ears you won't hear that pulsing sense anymore.
It'll sound like a tremolo effect with your ears with loud frequency around 10Hz or 11/12Hz and below. Assuming you aren't using headphones and using a sub/subs. I've not tried it with headphones because most have too much harmonic distortion to actually play loud enough (110dB minimal preferably more) at 10Hz area.
@@JoshM7 I see, you're dying on the hill that (almost) any frequency is audible if you turn it up enough, that's true.
Counterpoint: You could have just said that instead of typing 4 paragraphs of technicalities
@@mr_bear6362 Hey it's RUclips comments. I like to ramble. Just ignore me if you don't care to read the paragraphs.
11:16: ATH-M50-BT2 bailed around 30Hz. Also, heard Floatplane works pretty well for music, especially real-time streams, due to a different compression algorithms, but will require a monthly fee for your subscribers (which you will be mostly collecting yourself) to be able to watch anything there.
Beyerdynamic DT-770 here. cant really keep up, but i can actually hear 18hz on them. 35hz is roughly equal but below it drops off a cliff.
Lost it at (I think based on notes) 22 hz with my Sennheisers, but I will trust you that it goes down to 16.
With Beyerdynamic DT 990 Pro 250 Ohm + USB Stound Interface, i could heard everything! Nice Video and Sub!! Keep going 🙂
this is sub hotness🔥
You sure did rumble my ears with the 20->18->16Hz tones, amazing build
When the tones were played @ the end, were we hearing them from your sub using a microphone, or line out from your keyboard? My sub is audible to 20hz, but could see the cone oscillating @ 16hz. Nice build.
I love every video. If you change platforms, I just need to know which so I can follow.
I'm shocked, my Sony MDR-7506 cans actually played 16hz. 😂😂
because you played the video above 1x speed
My custom he4x in 3d printed port feed folded cans. Stall hard at 14hz.
But they took 5mo and a custom ai model with over 40 million iterations in simulation and over a dozen sls prints to achieve the ±1.2db response from 18hz to 18khz
@@ZoeyR86 wtf, that sounds awesome, have you posted any info about that anywhere?
@@dimatter i think it was because I was in a very quiet room. No where near equal loudness, but they produced something!
@icarusix8750 nope, I build ai models, and I'm a hardware engineer by day and a mix of spl and sq audio nut by night. I have an spl demo box (2006 scion xb with a 6th order wall tuned for 24-55hz running 6x sundown ns v6 18's on a 3 of d4s jp73's in the doors is a 4way setup with 10"' 6.5" super tweeters and horns. Each door has a pair of jp234's

Everything is dmx controlled, and I build custom lighting tracks using custom software to sync the light to movies.
I have OCD and when something gets my attention I tend to take things to far
Great choice on the sub, I ran stryke way back and theyve only gotten better since the name change/rebrand. Would be cool to see you do something in car with one. As far as other platforms go maybe floatplane would be a good place for some stuff. Audio based collab with ltt might be interesting.
Im using a single 18" sealed in my home studio as well. Similar box design as well with similar bracing for the same standing wave issue. Really like those corners might have to come up with my own version.
Whoa! That's impressive. My Sennheiser Momentum 4 headphones are more amazing than I thought!
I'd be interested to know how the initial equal loudness curve was generated. Was purely based on Fletcher-Munson curves or those plus measured room response at the normal listening position? I'd have to guess at the latter as some DSP corrections are then applied. But then I'd have to ask which F-M curve was used, as the tonal corrections vary with SPL.
As always, the platinum standard to which all other speaker building videos are compared!
I have Peerless STW 350 a monster of a driver wanting to make a killer sub in 70litre sealed
they stopped productions of that woofer as far as i know, maybe some issues with qc. certainly hope your last a lifetime. impressive woofer for sure.
I was watching on my iPad and of course all I got was 80hz and above. Switched to my JBL Endurance Peak 3’s and sure enough there was some bass (duh), but surprisingly while rated to 20hz, the 16hz was just as audible. Now if I could just get my truck to do that!
how on earth did u film this so smooth. looks like u had those hollywood camera train tracks
Good to see a new upload from HexiBass!
I like the build and lots to learn in this one.
Some other audio channels have a second channel for the audio demos to run on...that are no monetized.
Rumble side channel. My cheap and 15 yr old home theater setup heard 40hz just fine but everything tapered off after that... but I had my sub turned off and that was just the 6" drivers in the home theater speakers. I could detect all the frequencies down to the lowest but at minimal amplitude.
Your work and videos are always top notch. You just showed me something I don't need but really want now lol
Excellent video production quality! However, I think it should be noted that a low Fs sub driver should only be a priority when not utilizing equalization and/or using low-voltage amps.
Higher effective motor torque improves impulse response and a stiffer suspension lowers the box size, with very similar SPL at the Fs of a low BL/soft suspension driver.
Regular 2.1 setup didnt keep up with anything below 30Hz but my Beyerdynamic DT770 headphones through the SPL Crimson didnt disappoint :) massive sub you got there :D definately envious!
Tool Time.....nice!
MY Sennheiser HD559s stopped producing the bass a couple keys before 20, but I could still hear the air moving, lol
I been looking for your channel for weeks, 3d print a back for the ROG Ally X to make it sound better? I noticed after playing with APO equalizer and hesuvi the sound was amazingly not bad, but needs some tweaking like a custom tune profile. Who 3d print's small speakers and tunes them? You! I think this is as much in your wheel house as possible. I can't convince you to do it but I thought of you instantly when the idea popped in my head so just thought I would put it out there.
