Latest track:

"Funkenspelunkin" as featured in the April 2014 Home Theater of the Month

This thread is dedicated to deep bass music tracks. These are tracks that typically contain audio elements below 16hz, which is commonly considered the lowest note that needs to be reproduced... at least amongst the audiophile set. But LFE addicts know there is a whole world lurking underneath that! LFE addicts know of a different world, one the can best be described as follows:

"This thread is posted the DIY Section because 99.5% of mass marketed subwoofers cannot reproduce the sub 15Hz material contained within a number my tracks. While many my 'Dub King' tracks will test the limits of those widely known ID and BB subwoofers, only the most capable systems will have the ability to reproduce the songs as originally conceived. This is usually the case with many setups, and the limiting factor will change from track to track. Some will test the amp's current draw and cooling capabilities; others will test the driver's excursion limits! All the tracks will test the room itself and how well you have controlled your bass waves. Nothing is more 'invisible' than infrasonic bass, and most people don't know what they are missing. Are you among the few who can reproduce these tracks?"

Download some songs and find out. Members are STRONGLY encouraged to be careful with these tracks, if you have a true full-range system these tracks will push some serious decibels out in frequencies some stereo systems simply ignore. Check the charts first, so you know what to expect, some tracks are balanced; some are very, very heavy on the infrasonic content, because I'm really trying to shake the listener, not create 'sound' per se and sometimes that takes a lot of signal!

Members are also encouraged to post 'excursion videos' demonstrating infrasonic playback whenever possible

"Throbberizer Dub"- this is a definite system-tester. The bass line goes real low for most of the track but in the final 45 seconds it goes subterrainean... the first ultra-deep note is at 2:48 - if your sub plays it properly (you gotta really feel it) you are golden. For many folks, the woofers are just going to move silently.

OK Here's the first track, which is one of the toughest to play I've included a graph showing the frequency spectrum you need to be able to cover to play it back properly. Good luck reproducing "The Joy of Minimal" properly...

Another seriously brutal track, "Kablam Dub" shakes the foundation at 11.7 hz - it also includes some radically massive drum hits at 2:22 that might be mistaken for bombardment!

The bassline in "Logical Conclusion" has been described as a 'big bloppy thing' but actually it's a waveform crafted in a Moog synth, which accounts for it's 'fatness'. That and the fact that it digs down to 11.7hz

Last track for today: Major Dubbage, a signature piece for me. The bassline here has strong subsonic elements that start at 10.8hz, but all the frequencies in this track are balanced and the infrasonic ones are used to create a sense of infinite space to the audible bass. It's a great audiophile show-off and test track - across the whole frequency range. Pristine audio because it is 100% synthesis. I'll see what I can do about getting a high-bitrate version posted.

the more common way to present such sound is this way:



the joy of minimal. the lower end of the bass is concentrated in the 15-20hz region. not really much of anything below 15hz.

i'm not sure what your point is?

Listen. It's All Good.

Awesome, I'm new at this so thanks for the tip! I'm downloading Spectrum Lab now> I will have to read up on how to use it though.

The point of the thread is to provide links to tracks that I have created, which are free to download, that contain infrasonic content. Nothing more. Updated graphs are forthcoming.

gotcha.

getting spectrumlab setup is almost impossible unless you follow one of the guides. there are some guides out there that will walk you through exactly which boxes to check on which pages, but i don't have a link for you, as it has been a few years since i set it up. i'm sure somebody will link you up.

Listen. It's All Good.

I wanted to figure out Spectrum Lab before I make more official posts, but here is another super heavy hitter: "The Conformist" dub

It's a glitch track so I would not call this 'easy listening'

OK one more for today: Dupsplatter

The bass in this track has a funny habit of feeling 'directional', as if you are being shaken left to right and forward to back. Very tactile. Brief bursts of drums break up the ambient weirdness but even without a beat, Dubsplatter is a butt-shaker first and foremost.

soundcloud stream: https://soundcloud.com/psychedelicious/dubsplatter-the-evolution-of

If anyone has a link for a tutorial on setting up Spectrum Lab it would be appreciated.

OK I've got my first 'excursion video'. I'm pleased to introduce my highly temporary subwoofer, a 2 cubic foot car box fitted with a Polk Mobile Monitor 15" DVC 4ohm driver, powered by a Crown XTI-1000. I'm powering each voice coil with one channel from the amp at 4 ohms. Combined power rating on the woofer is 425 watts continuous, so figure just over 200 watts per coil... and the Crown is putting out 500 watts/channel into 4 ohms. I feel like it sounds better than wiring 8 ohms and mono-blocking the XTi, which is supposed to offer 1,200 watts at 8 ohms. It just seems like having two channels allows more bandwidth or something. I'd love it if someone had an insight.

Minimal mods include smearing 10 lbs. of duct putty (plasticine) into all the inside corners and across the entire back wall, for resonance damping and for additional air-tightness, then about 2" of poly fill was placed on top of that. The box is sandwiched between 18"x18" paver stones... one on the bottom and three on top. Each 'layer' of the sub has strips of duct putty which compresses and bonds the whole thing together, although not fully permenantly, just enough to make the whole thing one large, non-resonant solid mass. The final sub weighs just shy of 200 lbs. and rests on top of felt/rubber sliders, with the felt side down so I ca move it by pushing... but it will not move on it's own no matter how hard it is hitting.

This really is a placeholder sub while I do my research and decide what to build for my first true DIY sub(s), still it's done a great job considering the stones, putty, box and driver cost under $200 total and it does a legitimate 16hz - although tripling the box size would buy me 3-4 decibels in the 10-20 hz range and that's appealing. The reason I tried the Polk MoMo is that it modeled nearly identically to the LMS Ultra 5400, in terms of linearity and the degree of falloff (slope & curve?). The big difference, of course, is power handling and displacement. Still I wonder if 3-4 Polk MoMos would perform similarly to one Ultra because the price is so good on the MoMos, and the benefits of multiple subwoofers is apparent, that approach is something I'm considering, even though I'd love to have nicer drivers. I'm still not ruling out getting one Ultra, FWIW... but I gotta say I like the Polk a lot and it is a Neo driver which is one reason I had to weigh down the box so much, the sub-woofer itself weighed almost nothing.

My camera does not have a great Mic, you can't hear any bass, but rest assured my internal organs were shaking.

So, without further ado... "The Joy of Minimal", played in the studio in which it was created.

2 cubic foot car box sub with a 1x15" or so slot port? what is your tuning frequency?

if you want to recreate the bass that you create :-) what you want is something tuned right around your lowest note.

16hz tuning would be a good start, but you could go a little lower...your cab is probably tuned to around 35hz or so. your driver is unloading below that point and losing a lot of spl in the current configuration.

Listen. It's All Good.

i was just working off your picture. it appeared to have a 1"x15" port.

if you want to be the dub king, a largish ported and tuned sub to around 16hz is a good start. sealed are great, but give up quite a bit of efficiency around tuning, in some cases 10db, which is 10x the number of subs.

if you want to be the king of dub kings on the cheap, have a look at building a tapped horn tuned to around that same frequency. it will be huge, but so will your bass. it will also need some eq'ing out of resonances. here is an example, one among many:

http://www.avsforum.com/t/1420594/hornsub-with-lms-r-how-to-construct/30#post_22241565

if you have the money to just fill your room up with woofers, amps, and power lines, that is an option too.

Listen. It's All Good.

UGH! I can't wait till I get back home and can start building my two 18" LLT towers. They'll be about 650L tuned to about 12Hz. Should easily have useable in room response into single digits. As I understand, LLT get you less THD in the audible frequency band at the cost of being absolutely massive. Sealed is smaller at the cost of having more THD below about 30Hz, and massive amplification requirements. Whichever route you take, your neighbors will likely not be happy since you have a shared wall. Might want to do your listening while they're not home... even then you may well shake things off their walls!

I know there is some music out there with single digit frequencies. "Bass I Love You" with it's lowest note at 7Hz comes to mind. And Opus Dei has a powerful hit at 3Hz. Very few people even in this forum can reproduce that at mreaningful levels. Notnyt could, but he's got well over $10,000 in subwoofage and amplification alone. I believe Bosso is also able.

3 hz is stupid and that's just a visual effect. Coil did that 20 years ago on 'her friends the wolves', back when watching woofers move really slowly seemed somehow mystical. If I use infrasound, it's gonna be something people can feel.Yeah I'm gonna try and 'feel' frequencies down to about 12 hz, but I know that there's literally nothing there when you get to single digits. As for my neighbors, they hate me already, long ago I decided to NOT make friends with them, knowing that would never last.. At least it's a Philly rowhouse, so there's two layers of brick between us. Finally, he's a pianist, and sometimes I hear him practicing, so tit for tat.

edit - I'm wrong about 3hz, you absolutely can 'play' it and see it and feel it.

Man, for some reason I hate that song... I think I hate the fact that it's become the defacto go-to-bass song for the car audio scene. I honestly don't think I have ever heard the words to it... lol

I never knew it got down to 7Hz. I guess there are some songs out there already for those uber capable systems. I just never knew because I wasn't in the "in crowd."

I'm glad to see this thread has gotten some traction. I figured the DIY guys would appreciate it more. None of the other ID or BB sub owners would even know what they were missing. I'm looking forward to frequent updates.

It is so trivially easy to compose music with whatever frequency you want in it, it's not like the virtual oscillators are limited in any way. We'll have AVS DIY 'exclusive' tracks coming soon, with deliberately ridiculous low bass. By exclusive, I mean I'll keep them 'private' for at least a month.,, but always free, uncompressed 24/96 wav with download links. First one will be this week, promise!

I never knew it got down to 7Hz. I guess there are some songs out there already for those uber capable systems. I just never knew because I wasn't in the "in crowd."
I'm glad to see this thread has gotten some traction. I figured the DIY guys would appreciate it more. None of the other ID or BB sub owners would even know what they were missing. I'm looking forward to frequent updates.

OK I admit that I saw kryptonitewhite's ceiling fan video on youtube. can't tonight, he's got 3 hz manifesting as vibrations in ceiling fan blades. I guess I'm going to have to go down to 2 hz.

Maybe just do like 1 or 2 tracks that low and throw out some SERIOUS disclaimers... I think there maybe only 2 or 3 people I've ever seen that could remotely come close to having fun with that...unless someone out there is rocking a rotary sub?

Do we know of anyone?

Except he didn't, he had harmonics of those frequencies.

As I understand, LLT get you less THD in the audible frequency band at the cost of being absolutely massive. Sealed is smaller at the cost of having more THD below about 30Hz, and massive amplification requirements. Whichever route you take, your neighbors will likely not be happy since you have a shared wall. Might want to do your listening while they're not home... even then you may well shake things off their walls!
I know there is some music out there with single digit frequencies. "Bass I Love You" with it's lowest note at 7Hz comes to mind. And Opus Dei has a powerful hit at 3Hz. Very few people even in this forum can reproduce that at mreaningful levels. Notnyt could, but he's got well over $10,000 in subwoofage and amplification alone. I believe Bosso is also able.

Have a look at these guys, tuned to around 11hz, respectable but take up a LOT of space...

Yup, those are what I'm planning to build, but they won't be behind a screen. So they will be a "prettier" version.

KW is gone? Wow, I missed that one. I found the memorial thread. I also deleted my post in this thread.

Still confused? Read "

No problem at all for the Wolfhorns... they'll literally break the room before they break themselves biggrin.gif

I like your stuff.
