^^^ Awesome, thanks for the link!! I checked it. I’m sure I’ll do the same thing with adding the BKs to the BOSS when I try it, because I love a certain something that they can add to a TR mix I’m kinda doing that now actually with the BKs, adding them in for extra TR effect that I love in that 12-25hz area (they can be so good in this area and bring a certain type of violent feel that I love), while using the MAs (and VNF subs) as a solid base/bed for fullness, slam and ULF/LF TR.

This is a shot of Lone Survivor that is know to have the 7hz , the app picks it up here clearly on the X and Z axis. Thoughts

Note that this signal is not ideal for VS because of the amount of content > 50Hz however it's fine for that 7Hz and 20Hz tone. I think this agrees with the earlier WN measurement though in that either VS isn't accurate <10Hz in this case or the response drops over heavily. It is hard to get really strong TR under 10Hz though for many systems so this might not be surprising.

Vib sensor lines up with that. Lower intensity at 7hz but it's on it.

@3ll3d00d did you say you did some comparisons between VS and your setup? I was looking for them but you know how difficult it is to find things on this forum sometimes. Can you share a link? If your setup is more accurate <10Hz I'd probably buy what I need to assemble one. Or was yours more accurate higher up but suffers from the same rolloff down low?

It uses an mpu-6050 so that means

it can measure to much higher levels
it is much lighter so no need to weigh things down just to get useable data (which distorts the results above about 25-30Hz)
It is lighter so is easier to attach securely to whatever you want to measure
It supports multiple sensors concurrently so you can measure across a seating area more quickly

No problems measuring at v low frequencies either

The software can be moderately temperamental mind you (fiddly thing reading data over a serial bus reliably)

I will look for links later, I did compare at some point

Jeff.....if you really want to match the rising slope PvA at 7Hz that dood posted, you would have to go back to the stacked isolators and get your kidney belt back out. That rising 7Hz signal at over 2 mm displacement would start to cause some internal organ damage!

Pierce 18

The only setting I changed in the minidsp for the 12" Dayton was the Lp filter to 60 hz. The HP filter is off, which is how I run the 18. I pushed the Dayton harder than I would have in normal use for the sake of keeping it fair. The results show the 18" beats the 12". Keep in mind this is a 1 to 1 comparison on a single platform. I will be building smaller riser

The Dayton has a higher Mms and stronger motor compared to the jbl, I believe the Cms is almost identical. that said I would think they are close enough for comparison.

After having the 18 for a week I couldn't go down to a 12. It's just not a fair fight, different experience. I think it comes down to TR of the 18 vs 12. While the platform with Iso's is creating TR so is the mass and movement of the driver.

^^^Yes, so happy to see this when I opened this up!! Thanks for posting all these with the 12” as well GK to go along with the 18”!!

These look fantastic as well compared to your 18” IB driver. About 10db lower in intensity level on both EOT and WN0-50hz though. With 3 12” on a platform may be more equal.

Otherwise they look pretty darn similar across the board! And look at that extension showing down to about 8hz or so with that peak before dropping off, a little deeper than the 18” actually (that little peak anyway, otherwise still very similar (this could vary a little with each reading anyway so …)). Its deeper than just about all other VS readings I’ve seen with 5lb weight no matter the component, even though it should be showing more, but as we’ve talked about some recently, VS usually doesn’t read well (or near strong enough in relation to the other frequencies) under 10hz for whatever reason and drops like a rock fast with WN0-50. Why it shows deeper here, who knows, but cool!!!

Also, there is a bit of a difference in axis involvement as well. It’s still real close overall, but the main difference I see just by glancing at the two quickly side by side, up and down movement (Z axis -BLUE) is more active out to about 27ish hz before dropping off and forward to back (Y axis -RED) taking over. This looks like it was happening at about 20-22hz on the 18” IB driver in comparison. Whether this is just a difference in construction of the platform or maybe having your LPF set differently between the two possibly, or other, who knows. But I am glad to see this as I’ve found I really like the up and down movement in that 20-25hz area that the BKs really seem to be great at, at least they were on my couch that I previously had them on, giving it kind of a trampoline effect that I loved. Whether the BOSS would ever feel like this IDK, maybe, maybe not. Of course, while still feeling natural hopefully, which sounds like the BOSS is very natural feeling from all the reports so far.

How does it feel compared to the 18” with them level matched, or close to it anyway? More aggressive, faster or slower etc. Obviously, the 18” will keep on giving where the 12” will eventually run out of give on a 1 to 1 comparison. I know you said you could never go back to a 12" after experiencing the 18", but still curious as what the differences feel like between the two.

Thanks again GK for posting these results!! Awesome objective info and is very informative! That said, I’m sure it has to be experienced to really know what we all want to know, which is how it FEELS But these VS measurements are important too IMO to give us a picture of what’s actually going on with intensity across the board and axis movement as well, at least in the 10-30hz range.

Great stuff here!!

@SBuger , I used the same platform. I just mounted the 12 face up and use the OSB square to to give something to mount to. The magnet cutout was 1/2" to big. I tried to keep any variables out of the equation. The Dayton has a much stronger motor and Lower QTS so that could come into play.

The Z axis motion is the biggest difference. Its the shudder it produces, much more intense. Some things are overwhelming but Im becoming immune to it little by little. The trampoline effect this has covered, quite natural. I would LOVE to put one of Stereo Integrity's 24 with 1000gm mms in here Need a dbl riser so no joy on that.

Honestly I don't see how anyone would be disappointed as Tim has it laid out. My NF never gave the experience this does. The lack of spl changes the experience to be sure, you can feel the spring in the suspension of the driver.

I watched Dredd and Underworld Awakening last night, Noticed some things in Dredd I never did with my IB. Underworld was awesome. Battle LA right now

LOL about the 24", the Rob Hahn theater has a 24" under his second row middle seat....crazy! You could be the second person to do it! He later said, he wishes he would have done subs under more of his seats.

Looking forward to seeing what you next move is for another BOSS!

Yes, adding 2 more will increase intensity almost linearly on a 4x8 sheet of 3/4" plywood with the prescribed isolators. Over 3 JBL's per platform, the increase starts to diminish with the BOSS platform as prescribed.

Lots of different dials to play around with in a BOSS setup, which I think will be cool to see how those different dials will be turned by the AVS community. Maybe even a few more dials will be discovered....I'm hoping so!

Im not sure the rice on the phone is a proper test. Our body is getting the feeling through the seat. Water occupies roughly 50% of it. The phone placed on the lap with a ziploc full of water on top would be more appropriate.

JBL response in a BOSS configuration

Here's a video I shot back in December after my first concept build with the back row riser BOSS. This was exciting to see excursion at 2Hz with only 80 watts of power. That inspired all my BOSS experiments and how the final BOSS design was finalized. Pretty amazing for a $30 driver and only 80 watts!

The sound you hear in the background between frequency changes must be from the original author. My guess is a sine wave frequency generator was being used for the signal and the clicking noise is some kind of frequency selector knob.


Also, a few videos showing the back row BOSS and front row BOSS's in action

Front Row BOSS (5 seats on 4x8 sheet of plywood) - Lone Survivor Chopper Drop Scene


Back Row BOSS (5 seats plus a third row bar on the back row BOSS riser) - Lone Survivor Chopper Drop Scene


Front Row BOSS - EOT intro


Back Row BOSS (bar table) - EOT intro

fairly sure that all of these discussions have been had in this thread before (or the other one, I forget) so it's is worth going back and reading them. @coolrda did most of the testing on this and conducted an awfully large no of tests in various circumstances. This doesn't mean there isn't some other angle to cover but there is significant risk of repeating work already done.

tl;dr The rice on the phone is a hack for the fact the phone is much much heavier than an accelerometer. Ideally you want an infinitesimally small accelerometer perfected attached to the device under test. However a phone is readily available and a bag of rice produces a pretty close approximation at frequencies under approx 25-30Hz so it gets a decent job done quickly/cheaply/easily.

the affect of pressure/intensity on other parts of your body is a different subject again, no obvious (readily available, i.e. not costing 0s of 000s) mechanism for measuring this. One poster on data-bass did come up with a way of measuring certain aspect (velocity iirc) of this, bit complicated to interpret though to say the least (quick google shows some data in http://data-bass.ipbhost.com/topic/5...#comment-17931)

Similarly the perception of different levels of vibrations on different axes on different parts of your body is another subject again, there is an assortment of research on this but it's mostly health and safety driven (some of it does cover a seated individual though, there is a link to the research I used that suggested a way to sum x y z values somewhere).

Well if you know anyone near the Paper Street Soap Co. we could try that instead

@3ll3dood not trying reinvent the test, just thoughts and I did not see it in thread as i went through it but I could have skimmed over it.

This is a cross post from Tim's thread


Ok, I feel like a dumbass. I deleted my previous video, when I attached my Iso's I had a temporary screw which cuts the TR in half. This starts at 5hz and goes to 10hz. At the 1 minute mark the noise is me trying to turn the signal down in REW so the coil doesn't bottom out. The platform was moving so much the keyboard was not responding.

The light reflection shows the movement of the platform. My reason for staying doubled is I can keep TR at low volumes, movies that need boost can get it and those with too much I can turn down the amp gain.

^^^^^ @Gorilla Killa Now that's the TR we know and love from the BOSS!

3 JBL's on a single platform will reach down to 3HZ.....like a BOSS!

I really like GK's use of double isolators to enhance bass on movies with filtered bass....that's a waaaay cool idea to get back some of that ULF in lot of Blu-ray mixes!

Awesome idea Jeff!

Since there has been some action on the VS graphs lately, i am copying some posts over here, so maybe more can join. MA’s, BK’s, BOSS, NF, or whatever, posts your results

What do you think? Used a 4lb bag of sugar for weight.

Forgot to mention those graphs were obviously with BEQ applied for The Meg.

I noticed how most my measurements drop off quick at 10Hz in my seat, but maybe that’s just VS not reading well that low; oddly, the direct on the BOSS measurements read very smooth down well below 10Hz to DC, but surely that’s not totally accurate, as I really doubt these little drivers are capable of that kind of intensity in the single digits. Could be a resonance from the Crowsons that sit on the platform.

Pick another movie or two and I’ll try and do some as well to compare, as I’m curious too. Maybe the ones @SBuger posted in the BEQ thread are a good start since they’re time stamped.

I thought the Hulk street fight scene and War of the Worlds pod emerging were about to rip my couch/platform apart the TR was so visceral and sharp, so I’m wondering how those compare. They’re much longer though, maybe do just a minute of each and let me know the timestamp or vice versa. I might record those two scenes when I get home.

Yep anything in TIH should be awesome to VS, and WOTW. You might also run the White Noise 0-50hz file as well (there is a link to it in the VibSensor thread), or even a 0-50hz sweep, just to see how your overall TR looks from at least 10-30hz. VS seems to be the most accurate in this area, but can show over 30hz to 50hz pretty decent too. But under 10hz (at least not when singled out like a specific sine wave), usually doesn't read so great, even if your getting great single digit response.

Curious how these compare to your setups @DesertDog @SBuger @Nalleh :


Edit: added a BR 2049 scene as the 25-35Hz bass is pure insanity with the BOSS.

And here is a quick guide to get VS running by the TR King himself, :

The VibSensor is an awesome tool to show what's going on with your TR as far as balance across the board as well as the intensity. I see no reason at all that it would not work well to compare these subs in another way in addition for TR. VibSensor for the objective part of the comparison to compliment the subjective when it comes to Tactile Response

That said, even if the TR results come in very close looking, they could still possibly feel a bit different, but probably not by much. The VS doesn't lie when it comes to Low Frequency Tactile Response at the seat, and shows pretty much exactly what's going on with your TR at the MLP in how much shake it's getting at all the frequencies.

You can use any material you want to run the VS measurements on (specific time stamps from movies, White Noise, Etc).

To start with though, I wound think the best would be White Noise 0-50hz. This would show the TR very well between the two across the board in LF and ULF area. Well at least it will from about 10hz to 50hz. The VibSenor has never shown under 10hz well at all and just drops off like a cliff, even if there is a good bit of under 10hz TR going on. No big deal though, as down to 10hz is good and right around these subs port tune.

To give you an example of what a VS graph looks like with the White Noise 0-50hz, I ran it on my system right quick this morning with my Subs Only (no TT in the mix). I ran it at -10 MV (Master Volume) since this is about the loudest I ever listen to movies and also my normal sub trim bump of about 10db (so about where you guys did your comparisons at IIRC). Or maybe you guys did them at -5db. Either way is fine. Anyways, the settings I used puts the bass right around reference or thereabouts down to 10hz and under.



^^^
So what does all that show? Easy ....along the bottom of the graph shows the Frequency 0-50hz. It labeled across 10hz increments (i.e 10hz, 20hz, 30hz moving left to right). Then on the right hand side of the graph, it shows the intensity. The higher it climbs, the higher the intensity. They are labeled 1e-04, 1e-03, 1e-02 and so on climbing higher and higher. So for example, 1e-02 would be higher than 1e-03.

Then the BLUE, RED, and GREEN lines (axis) are the TR levels that were recorded. They span all the way across from 50hz on the right side all the way to 0hz on the left side. The BLUE line is the Z axis (up and down movement), the RED line is the Y axis (forward and backward movement) and the GREEN line is the X axis (side to side movement). Usually the closer these lines are in relation to one another, the better, giving a more powerful balanced TR feel.

If you look on my graph, all three axis are pretty decent in relation to one another as well as the 'intensity' level across the board being pretty similar, except in the 10-14hz region where I get a big TR spike that jumps about 10-15db on the Z axis (BLUE). This is from my suspended floor, as these frequencies really excite the floor giving this extra bump in TR. I use to cut it a bit, but really like the way it feels down this low, so I just leave it in there now. @toddct (and even @imureh ),you may have something similar going on as well at certain frequencies since you guys are on a suspended floors too. The White Noise 0-50hz file when VSed will show if you do (it shows what going on with all frequencies across the board up to 50hz, excluding under 10hz of course since VS doest read well at all under this point).

So there is all that. Hopefully that all made sense

So how to do this:

If your guys are interested, it’s pretty easy for the most part. I use the IPhone 6 to run VS. It works great on this phone, but should work on others as well.

Steps for getting the White Noise 0-50hz file:
1. Go to the VibSensor thread HERE
2. In the 1rst post, click on the link WN and Bursts.
3. Then download the file named White_PN_131072_48000_0_50.wav
4. Burn it to a disc or use a USB stick or drive to play it through your Blu-ray player.

Steps for taking the measurements:
1. Download the VibSensor App (free app I think)
2. Open the app once you get it downloaded to your phone.
3. Press the acquire button at the bottom of the interface.
4. Before you take the TR reading, on the screen that comes up, type in the Title: something like FV25/WN-0-50/-10mv for the Rythmik.
5. Then on that same screen set a 5 second 'Delay' (so you have time (a count down before it starts recording) to start the phone once it's placed on the seat, and press play on your White Noise File (or time stamp on a movie).
6. Then on that same screen set the 'Duration' of about 10 seconds. 10 to 20 seconds is good. Try to keep them to not much over 20 though or the lines for the reading get a bit squiggly and harder to read the longer the time.
7. Take the reading: 1. Place the phone face up on the surface of your seat cushion with the top of the phone facing forward. 2. Press ‘start’ on the phone to start the 5 second countdown (once it counts down 5 seconds it will start taking the VS reading for the duration you set (10 seconds for white noise should be fine). 3. In that 5 second countdown, place a 5lb bag of rice over the phone and press play on your remote control to play the White Noise 0-50hz file through your blu ray player to capture the reading. Use stereo. You can use Dolby or whatever, but I find stereo to be the best.

Important note: you’ll want to use a 5lb bag of rice on top of the phone for accurate results. We’ve tested different weights in the VS thread back when I was real active in it a couple of years ago and we all found that 5lbs is the best making it the most accurate in the 10-50hz range. It’s just enough weight to keep the phone in contact with the seat surface at all times (no weight and it bounces and moves around too much) but not too much to as skew the readings too much. You can easily pick up a 5lb bag of rice at the grocery store.

DONE - press the ‘View Data’ (right next to 'Aquire') at the bottom of the phone. Press linear view to see it appropriately. Snap a pic if you want to post it. You'll probably have to save it to a jpeg file first though in whatever program you have.

May sound kind of complicated at first, but really it’s pretty easy after you do it once. Plus it can be kind of fun sometimes

You can also do this with any time stamp in a movie, which really can be fun to see what kind of TR your getting on some of your favorite bass scenes in these movies. I did an 8 second one last week (for fun) from one of the scenes from ‘The Incredible Hulk’ that I'll post as well just to give another example (from a movie time stamp if that's what you want to use). Time stamp and settings I used are in the 'Title'. It’s when Edward Norton falls from the chopper and hits the ground. Lots of LF and ULF



If you guys decide to try this to compare the subs even more, I hope this can help and wasn’t too confusing.

If your really into TR from these movies (which I think most of you guys are ), VIbSensor is an invaluable tool to have in your bag of tricks for many reasons IMO to get the most out of the TR in your system. VS is to TR like REW is to FR So besides for just this comparison purpose of these two subs in this thread, you may find VS to be a great tool to help you get the most out of the TR (optimized) in your own rig, especially if you run TT's and NF subs in the mix.

Awesome thread and comparison you guys!!! I eventually went DIY with my subs for different reasons (mainly from a cost standpoint), but did have a JTR 2400 (older amped version) and a Rythmik FV15HP (I still have it and love it) at he same time and compared them quite a bit about 2 years ago. I pretty much totally agree with everything that had been said about the differences of the two and noticed it right away, as I had had the Rythmik already (and was really used to it) before I got the JTR. Both great subs for sure, but most definitely have different characteristics. I actually thought more so sound wise than TR wise though.

Cheers all and Happy Holidays!!


And some additional info from me:

I use MV -20dB as that is the level i normally listen to. Turn off Audyssey and DEQ(or similar depending on AVR brand) to get a flat signal to your "shakers" in this case.
I use a 2lb bag as i struggled to find anything 5lb, but the difference between 2 and 5 is much less than between zero weight and 2 lb(strictly speaking 2.2lb = 1kg).

Before taking screenshot of the results be sure to tap the "tilt" and "vibration" (in that order) button to get additional info from the measurement.
For the 6, 15 and sweep hz i use REW. Just run a normal sweep, no need for more than 0-50hz, but i just run to 60 to get all that VS can measure. And the sine waves from signal generator. I use via HDMI and channel 4(LFE)

Just ask if more is unclear.

PS: EOT is better than nothing

Thanks, I didn’t notice it adds the tilt and vibration numbers after selecting both prior to the screenshot. That would definitely help a lot for comparisons too. Here’s the crazy BR 2049 car landing with the additional info. I know it feels ridiculously intense to me, curious how it stacks up.



War of the Worlds, the 30Hz TR was the craziest and sharpest TR I’ve felt yet but similar to the BR 2049 scene’s VS numbers just a few Hz higher, 27Hz vs 30Hz. A lot stronger 10Hz effects sprinkled in with the tripod’s vaporizer/heat ray:

Yes, the tilt and vibration buttons adds vital info before you do a screenshot, and makes comparisons more valuable, so please use them too

You sure have some awsome TR now, no wonder you are happy with them

I am a bit between projects ATM, as i have removed my BK’s and installed a 4xJBL BOSS and not quite setup properly yet, so i can’t get any VS done until next week, but i will get to it then
