Gotta say though the placement of you guys standing will affect room acoustics and could render a slight difference in testing probably as much as the stands make especially the triangle base stands, you were standing right behind the left monitor and you will act as absorbtion, much thicker than a bit of foam matting

Everything in the room will influence his measurement. Moving the concrete blocks as a whole or as parts to a different position will make a difference. They should have taken the not used stands and themselves out of the room during measuring. Also this test doesn't show the difference in sound because of reflections created by the stand or sound difference created by the supportlevel of the speaker. But it is great entertainment.

Also, the difference in the resonance at 10-50Hz could just be noise floor because frequency response is rated for somewhere in 30ish range. Second the low frequency resolution is heavily affect by the FFT size (Gabor limit) so that can color how you see the response in the water fall. It would also be interesting to see what the standard deviation in the responses. Also, taking a high resolution fit you could use a student's t-test to see if the responses where statically different. I really loved the video it is nice to see people incorporate measurements into their decision. Finally in building acoustics we use things called tapping machines that drop calibrated weight to tap a floor to see how resistant they are to impact noise (foot steps). The tapping was the right thing to do and maybe gator should be tapping to products. I was expecting the concrete to more damped than it was.

These tests are invalid if they were randomly standing in high velocity (low pressure) zones of room modes of this studio.

The dips at about 180Hz and 270Hz are likely room issues. These frequencies would correspond to distances of about 6 feet and 4 feet. I imagine you'll find that raising or lowering either the speakers of the microphone will change those dips considerably. I don't know what kind of flooring you have, but I suspect that coupling to the floor is a problem with all your speaker stands. Have you tried suspending the speakers from the ceiling at the same spots? The screwdriver was a great idea, BTW. Many decades ago, Wharfedale used to build double-walled baffles in their speakers that were filled with sand. They were about as dead as can be when whacked with something.

@@dingdong2103 well, the acoustic treatment of the room seems to be non-existent. Better to check this first and then see how things can be improved, that's the logical way.

As people seem to be picking up on, the time domain (viz resonance decay) is going to be influenced by the absorption characteristics of the material/structures of the stands. For the concrete blocks, they (from your tap test) are quite resonant, but have minimal absorption. To increase the absorption, isolate the blocks from each other with a rubber like absorbant material (say the sound deadening material for car panels) and fill with a non resonant lossy material, ie sand etc. That should help by reducing the energy that can go into the concrete to make it ring, and then by absorbing the energy that makes it into the concrete after the stimulus is removed. So less energy should be absorbed and should also decay much faster.

I bet if you first painted or soaked the cinder blocks in a penetrating poly sealer and then filled them with sand, you would have markedly better results. It comes down to mechanical vibration in the end. Slap some cork sheets and/or dense rubber inbetween each block on top of that and your DIY setup will compete against the expensive stands. The "tone" or resonance of the stand is 100% negatively affecting the results. Remove as much of that resonance as possible and you are off to the races in a much better position. Why do we put tapes and towels on drums? Congrats on the milestone. Great content!

A few years ago I made some speaker stands using the solid version of cinder blocks, using one laying horizontally and two back to back stood vertically on the first to achieve the height I needed. I painted them with latex paint (2 or 3 coats) and 'glued' the blocks together using construction adhesive. I did this in the garage, then when it came to moving them to the listening room I 'noticed' the weight ... something like 75 pounds per stand. To my ears they contributed to a very good solid sound (despite me painting them to match the room color, wifey dictated their removal not too long after I installed them). I'd recommend avoiding the hollow blocks and sealing or painting them. I don't know if your room has a solid (slab) floor or not, but mine is a slab so coupling to the floor isn't too much of an issue.

No. Weight will let freqs travel and ring. You want decoupling. And as sturdy as possible. Loose blocks won't help. The weight distribution on the $1200 is off balance. That is why the pole under center of gravity is the best. Wall studio speakers rest on 4 poles per speaker. Even better weight distribution.

I'm sure if you put sand in the Gators, like most users tend to do, you'll find that you'll get similar results as the Anchors, if not better. I changed mine for three legged ones and added crushed glass instead of sand and there's absolutely no ringing when I tap the legs with a metal object. I can also vouch for those ISO Acoustic Pucks. I use them too.

Sound Anchors fills each stand with different types of sand/epoxy mixtures to deaden the sand. You can do something similar with the cement blocks and probably get the same results (meaning the "thud" when you hit them).

Don't be around the speaker when measurement is progressing. You guys seems like so big useful basstraps behind speakers affecting between 40-150Hz🙂

Where this test went wrong was the minute someone said that the video was sponsored by a retailer. At that point there was no chance that a product they did not sell would have any validity in the test. Common sense folks, there's no way you can get anyone to spend $1200 on a speaker stand if it doesn't win the test over some concrete blocks.

Speaking as someone who used to design and install Pro audio and video for home theater systems, these things carry some significance but offer variables that cancel some of the science. It is interesting to see differences but here is the thing, "you" are not a stable object. You move your head. If there were an apparatus, that you locked your head into that made it stable and kept it in the exact same spot every time this would be valid. There is also the fact that Bobby hears music different than Johnny does. None of us have the same exact hearing in both ears. There are also differences caused by hearing damage which happens to everyone over time. There are so many variables that point of position (although somewhat important) doesn't really matter. Acoustic treatment then becomes the most important thing. Canceling frequencies that build in a studio ultimately, are more important than the position relativity to your ears and your speakers. Headphones on the other hand are always relative to your head and don't have any room frequency build-up. The best way to mix would then be to use both. The monitors to hear what the music sounds like in a room environment and how the low and high frequencies build in a room situation (which will be different for everyone and anyone since we don't have the same room) and the headphones to hear it without those frequency builds. The flat response of the monitors is only important as a reference from one song to another and not "shaping" the music to "your" ear. Only the people that have the exact monitors as you do, the same dimensional room, the same acoustic treatment and the same hearing will hear the music as you do. That being said, you have a very nice setup going there!!! I enjoy your content and wish you the best of luck in future endeavors!

Most of what you say is true, but Floyd Toole and his colleagues at Canada National Research Council and later Harman-Kardon Research showed pretty convincingly that listeners prefer a flat frequency response, linear phase response, and "tight" waterfall charts. Even older listeners with degraded hearing. It is true that narrow dips don't matter very much, and that millimetre differences in head/mic/speaker position affect those. Broad valleys in frequency response are much more objectionable. Toole recommends listening to classical symphonies when evaluating sound systems. Completely agree about the importance of room treatments. Hard surfaces produce terrible sound.

Well. I was certainly not prepared to be that surprised at the differences. You definitely get what you pay for. Great video, and your pride at your 100K award was both wholesome and justified. You've got a new subscriber.

Before upgrading to Barefoot 01s, I opted for cinder blocks over sound anchors (to save some money). However, I didnt leave mine naked. I wrapped them with a sheet of thick black vinyl, got isopucks, and also filled the hollow parts with rock wool. Not sure how much of a differenve this made (as I didnt do A/B testing with them wrapped) but all I can say is that Im super happy. Along with all the other acoustic treatment Im using (panels, bass traps, MLV, diffusion) my room measures almost flat down to 32Hz using REW. Cinder blocks are more than sufficient in my room and I have no interest in upgrading to sound anchors...at least not yet. Great video!

I love tests like this. Acoustics is always sooooooo important for mixing and honestly I never thought to think about the sound of different speaker stands, but just if I had stands or not.

I think what you are seeing is in the difference of the rigidity of the different materials and construction. For the concrete blocks to behave like you thought they would, you would need to fill the gaps with sand and use mortar to make one solid structure. The combination of mass and removing the ability for the blocks to vibrate against each other would make them more rigid and contribute less to the sound of the speakers. When the concrete blocks are loose like that, they all can still vibrate. That said, the results from your sound testing did reveal some standing waves in your room. Parallel surfaces that are about 14.15 feet apart can account for that 80 hz standing wave (speed of sound divided by hertz). That can be fixed by making the surfaces different by as little as 5 degrees, or introducing diffusion blocks on even one side. The low end reverberation can be addressed with some bass traps.

The audio test must be done remotely with the room completely empty.

Fantastic comparison Colt and a big thanks for putting the effort in to do it properly and showing all of the measurements without smoothing. Just a few comments: The 80hz peak on the blocks might not be a resonance. Notice how it doesn't decay (it's flat), that's the kind of thing you get in measurements when you have some background noise hum. or it's really really long, did you fill them with anything? it is still better though, you can see the smaller sloped peaks get shorter and the slope of the lowest mode is steeper. The measurements for the Gator stands might look a little better because you're providing some bass trapping with your body as you stand behind ready to catch them! Also, did you re-adjust the height when you put the pucks under the sound anchors? It looks like the comb filtering in the high end has shifted up in frequency which is what you'd expect if you changed a path length somewhere.

The concrete blocks have huge air volumes inside and will resonate because of them. Like you, I built stands out of concrete blocks and measured them. They were terrible. However, I didn't use any flat blocks like you did, only the standard masonry units with the two large voids. I stuffed these with cut squares of recycled denim insulation until there were no more voids filled with air. They calmed down quite a bit and sounded passable afterward. I oriented the blocks so that the open sides of the voids were facing vertically, toward the bottom of the speaker. They essentially eat up any energy leaving the speaker cabinet directly downward.

Congrats Colt! Youre doing great work man.

The brick might perform better if you use a hollow brick or construct it differently. I'm guessing what caused the problem was the brick surface area. Its.huge compared to the stands. So it will certainly reflect more frequencies and might store more. Try reducing surface reflection area from the brick, that will be an interesting comparison.

Sound Anchors make a kevlar puck for the bottom of their stands that decouples the stands from the floor even further than the built in spikes. They made a huge difference in my room.

One thing to remember, the anchor stands cantilever the speakers off of the front of the stand posts while the $100 stand support the speakers under the center of gravity of the speaker. That makes them inherently balanced. That puts puts less bending stress into the posts themselves. The anchor stands with the excentric loading makes the post into a spring. The posts are probably filled with a sound deadening material (spray foam?). That makes them a well damped spring, but still a spring. But even though the posts don't resonate, the fact that they are in a bending mode, means that they may be allowing micro movements. And the speakers are also on a cantilevered arm. That would allow for more micro movement as the drivers move back and forth. Those micro movements may be what you are seeing in the waterfall plot and why it is not much better than the $100 stands.

Great vid Colt. Doesn't look like you are using the spikes and coasters. I've been using Sound Anchors since 1999.

What I was thinking too. I used to do that with hi-fi stands back in the day.

The reason your measurements were surprising is because you didn't measure what you think you measured. I promise you that all of the sonic differences you measured are due to very small changes in speaker placement. I understand that you used a laser device to get the speakers as close to the same location each time, but they must have been slightly different. Even 1/4 inch is enough to make a real difference in both the response and waterfall graphs you showed. The ringing you heard tapping the concrete blocks is at midrange frequencies, so that won't affect the bass range. And it probably wouldn't be loud enough to show on the graph anyway. A sine wave sweep excites that resonance much less than whacking it with a screwdriver. This stuff is very tricky to do correctly! When I measured speaker isolation, and proved it has no effect on competent speakers like yours, I kept the speaker placement differences to less than 1/4 inch. And even then there were small differences due to room acoustics, unrelated to the isolation devices being compared.

Hey, congratulations with 100 k subscribers!!

Great video. Thanks for sharing.

As a speaker designer, what surprises me is how many enthusiasts continue to confuse coupling with isolation. By using stands and spikes, you are coupling the stands to speaker and floor. By isolating the speakers using sorbathane or similar isolation pucks between speakers and stands, you isolate the speaker and sink remaining resonance in stands to the floor. By using stands you can fill with sand or similar deadening material, you reduce drastically resonances in the stands. The waterfall decay plot is very useful in seeing how these things work. It remains the case though that cabinets should be engineered so that panel resonances are kept very low, preferably -45dB on program or less, at their harmonic resonance points and that sub panels created by introducing internal bracing breaks the resonant frequencies up so that amplitude of resonance at any given frequency is drastically reduced. The advent of efficient mass loaded vinyl elastomer materials allows speaker builders a great sheet material to damp down remaining panel resonances.

Wow cool video Colt! Great job! The pucks helping that much doesn’t surprise me as much as the Gator stands being better than the blocks. But it does make sense in hindsight that the cavities could ring. Hmmm interesting! Sound Anchors for the win especially with the Focals! Merry Christmas!

Very interesting video! Thanks! And congrats for the 100K ! ;-)

Very useful test thank you 🙏

very educational, thank you very much!

Nice video and interesting results! How would you expect those results to differ with some of the more common home studio monitors like Yamaha and Adam and KRK vs the results you got with the Focal Trio, which is more of a professional grade monitor than a lot of home recording people might have?

Great stuff guys. I have built many speakers in the past as well as stands. the wood stands were filled with a chunk of metal and sand. never had any resonant issues. The cabinet had a partitioned wall inside and stuffed. Tightest sounding speakers ever

Really interesting! I hadn't realised how much of a difference: (a) the speaker stand makes; and (b) the acoustic pucks make. Yet MORE kit I'm going to have to try to convince my wife to let me buy...

THANKS COLT 🤗 VERY ENTERTAINING 👍💚💚💚

Filling the main tube with wax helps a lot, and also place the stands with rubber and foam on the top. I did it in my early years for the studios 40 years ago... Good stuff!

Thanks for sharing. Interesting.

Great video. My wife watched it with me and was engaged! How did you make your measurements? I am considering starting to use REW, can it provide the graphs that you used? If not what do you recommend?

That was really interesting and thanks for sharing the results with us. I did wonder if not having space under the speakers when using the concrete blocks had any bearing on the results I was also surprised at how resonant the blocks were when tapped.

Great Video Colt!

Thanks for the demo, I have been considering buying some blocks, now I’ll wait. Great info.

If you're thinking of using hollow blocks, some people fill them with sand. That should help.

Congrats on 100K!!!

well done, very professionally executed

Nice video bro. How do you like the new Focal Sub12? I have the Trio11's and was looking at getting the sub too. I actually want a second pair of monitors (closed box design) though. Have you heard the Ex Machina line yet?

Tapping test. Please consider: a. Removing the 85-pound speaker before tapping. b. Place a glass of water on the stand, Tap, check the ripple. i) Taller the wave, poorer the performance ii) Longer duration of ripple, poorer the performance

As always great review! I have concrete blocks and now I’m like damn, upgrade lol. Thanks for this Colt. You always keep it nerdy but very relatable to the not so technical, appreciate that.

Thank you!

Great vid! I have the same speakers, absolutely LOVE them. I have them sitting on Argosy stands that have the ISO Acoustics built into the stands... I bet if the concrete blocks were solid it would be a much different result (even as You tested the smaller yet solid block was less resonant and it was at a lower frequency with much shorter decay time). I noticed in the comments someone had said about dipping the blocks, great idea, (which would fill all the tiny air pockets in the concrete). Reason it interest me SOO much is that one of my best Friends, since knee high to a grasshopper, owns a company in Canada called Midhurst Granite. And point being is that although I do enjoy the Argosy stands I've reeeeallly been wanting to go out to his shop and make some speaker stands with granite. nothing fancy just a giant granite block (1 piece, One for each speaker) the proper dimensions to feel safe with the Tio's. My studio is on a concrete slab so there is no weight issues because I figure these granite stands would weigh anywhere from 1000-1300 pounds LOLLL. (He has special equipment to be able to move them)... My desk is a huge live edge slab of maple with gear sunk into it. ( I Love to build funky custom stuff, EVERYTHING is art!) Anyhow, in some time I shall do this with the giant granite block stands and let You know of the results. As well someone had said about fabricating the anchor stands, so true could make those very easy with a welder and 2-3 hundo of metal... Really appreciate and Love Your channel Bro keep uP the fantastic work and content! As You will!

Congratulations on 100k dude.

You have a way of explaining complicated points such as the waterfall chart very clearly and creating real interest - you should be a teacher!

Thanks for doing this analysis. It reveals what your ears cannot.

The recording of the sound anchors with the pucks sounded like it was playing natively through my speakers. That is really amazing. You could use that setup for film production.

Very interesting and awesome video!!
