    This is why it bums me out that this is only a metal channel.

      Because other genres are brainwashed into thinking tone wood and pickups make the difference in tone.

      Much of these applies to other genres. However.
      Even in metal gear can sometimes occasionally be specific. In industrial metal they often use gear in weird not normal ways to get new tones.
      A mixing board that's like 30 bucks and sounds like crap to create distortion.
      Or tweaking some specifics inside the amps that actually do tweak sounds. You can sometimes mod amps to do some cool extra stuff.
      But for clean tones. On acoustic guitars tone wood is real. But barely. Shape matter more.
      The reason vintage stuff in electric tones world has such variance in the vintage stuff is looser tolerances.
      You can get every bit in tolerances to clone any exact configuration physically for cheap. It doesn't have to be a price hike. Like 1200 for the most expensive amps with specific parts tolerances in the transformer or hand wiring scheme.
      Speakers matter probably more then that in most cases. Cab design matters alot.
      A few things can effect how strings vibrate. But nothing enough in a mix.
      Here's example of design mattering most. Old gibsons. And one other historic brand I think gretch or Martin used a historic scale measure from the 1800s in their guitars till the 60s.
      It's less accurate. But more about those subtle imperfections.
      So it matters context wise. Can you make advantage of Any of the little subtle things that can even effect tone to see I'd they cut through the mix in your genre.
      If you pitch correct and time align. Nah. If it's very raw with imperfections and feel. Yes. Cause if every note is a little less accurate but you have like perfect playing and stuff. And expressive playing. Bends can matter.
      But sometimes hilariously the cheaper stuff sounds better. Or the less accurate stuff matters.
      With modern instruments nah. Scale length. Amp or mic. Speakers. Cab design. Effects. Recording method.
      Room design matters more. Digital can effect that to tune for the room easier.
      But for general purpose. Alot of the same stuff still applies.
      I have a theory on why pafs do sound quite a bit different. And again is tolerances related. But that wire is now impossible to get. And not worth it since you have no way of knowing how it'll turn out. But essentially tolerance along the wire being less concise effecting the individuals pole pieces magnetic factor differently in terms of how hot or clean they are which is about all you can effect. But that'll effect how each string breaks up when driven causing the differences. Combined with old scale and more hand made and looser tolerances on intonation factors and yeah.
      Add in the coils being slightly different windings within each pick up. How hot and clean they are.
      But also means it's cheap to clone anything besides the pickups. Which you can effect with an eq pedal.... lol.

    Glenn, I've been designing and building hifi and monitor cabinets for years (as I design the speakers) and bracing makes a massive difference. The best way to measure the cabs for resonance is a cheap contact accelerometer like the ACH1 you can get from Digikey or Mouser in the US.

      An old friend of mine used to design his own stereo speaker cabs as well. It seemed like every time I went over to his place he had a different iteration of speaker cabs. I think his final conclusion for best sound was the best speakers you could afford and the least resonant material you could make them out of, so he ended up making the cabs out of cement. I think the take away for me was get the heaviest cabs you can...they will resonate the least. For wood cabs he used 1" plywood with tons of bracing.

      Do you understand why guitar and bass cabs often have multiple identical drivers, and if it's just two, they're usually side-by-side? That seems like a recipe for maximizing comb filtering, which most speaker designers would studiously avoid. They're also usually open-backed rather than having a normal tuned bass port, and they're usually not damped on the inside to kill off stray high frequencies. Seems super-weird to me.

    Back when we were all putting absurd systems in our cars, we used to build all kinds of custom enclosures. The biggest impact by far was always air space, followed by porting size, shape, length, etc. The stiffer the enclosure, the tighter the transient, clearer the high end, and more precise the low end. The material the speakers were mounted to had more impact than the rest of the enclosure, and the way that material was mounted, either floating or rigid, really effected some speakers.

    The fascinating thing here for me is that though I can tell the differences when the visual aid is present, as soon as I closed my eyes in order to take them away, I immediately lost track of which cab we were on and which cab sounded like which... I just started headbanging to the riff. And this was on the isolated guitars track. When it comes to the full mix, I remained hypervigilant for a change in the guitar tone (by watching out for which SOUNDED like Cab A) and kept guessing there were changes when there actually was none. Ppl really do listen with their eyes and I now know to not waste my time on this tonewood stuff because even though the difference is there according to what my ears heard, it is so negligible that it doesn't justify paying several extra hundred dollars based on what the tonewood is. Thank you very much Glenn, you're doing important work for the consumer here!

    I love this series. If it shows anything, it shows me that 40 years ago, when bands were tracked live, and the room was as important as the mic, the cabinet was more important than it is today. Even live, most touring bands are using front of house, and Ndsp modelers.
    Today, it’s almost redundant to have cabinets. Direct amp recording via technology, and direct tracking using modelers have kind of taken the amps, cab, and mic placements out of the recording process.
    If i were still playing live, I’d run a 1960B for the resonance it gives onstage.
    Again, thank you, Glenn. The time you put into these videos is greatly appreciated!

  • @TheTrueVoiceOfReason
    @TheTrueVoiceOfReason 2 ปีที่แล้ว

    Glenn,
    Well done on the use of the scientific method. It truly shows how the density and inertness of the cab affects the final outcome of the driver: the approx 510 Hz "woooo" of the particle board while the plywood and MDF are much more clean and almost indistinguishable form each other.
    About the only thing I can offer is that you did a close mic of the drivers, which helps to isolate the drivers from the cab. Yes, I know it is because you are recording in the studio and that's how it's supposed to be done, but the whole "tonewood" debate is about how the wood colors/colours the sound, and in order to do that, you will need to back the mic up to at least 16" from the face in order to get the interactions from the cabinet. All else being equal - same cab design, same cab build quality, same placements, etc. etc., just like you did - the real difference now would be how the cab adds to the drivers as you pull away, since each material has different resonance properties. You just might find a bigger difference between the ply and MDF, and more "mush" from the particle board.
    Before anyone else drops in, yes, cab design for the specific drivers has A LOT to do with how they sound: sealed, ported, open back, they all load the drivers differently, and contribute to where breakup starts to happen and what the range of the driver will ultimately be.
    So, if you were to re-run the same experiment with the same parameters but change the mic distance to 16" (standard for measuring "regular home" speakers), I'd be curious what further differences you might find.
    Oh, and, Thank you Glenn. You F'ing ROCK!

    @geraldbolso1899 2 ปีที่แล้ว

    Mechanical engineer here! First of all, thank you Gleen (or fuck you?) for making these awesome videos.
    I build custom cabs, mostly front loaded. The physical effect differences between front and rear loaded enclosures are well documented in almost any hifi enclosure design handbook. The main difference resides in the fact that rear loaded cabs are more focused in their projection. The wood cutoff acts as a tube, albeit being short and as lengthy as the baffle itself. This also creates a cavity effect in that space of air that accentuates certain resonances, mostly mids and highs, depending the the size of the cutoff.
    In front loaded cabs that doesn't happen, as the speaker cone isn't limited by that small cavity, so the spread is wider than in rear loaded cabs.
    Additionally, using the same enclosure, the volume of air trapped in a front loaded cab is larger than a rear loaded one, although its minimal. This affects the standing wave effects and the main resonance of the cab itself.
    And lastly, and purely speaking about mechanics and the forces experienced by the cab: a front loaded speaker pulls the entire structure on the same direction all the time, whereas a read loaded speaker pushes the baffle in one way and the rest of the baffle is pulled along with it, so there are some couterreacting forces going on there.
    Anyway, those are my two cents!

      @@alexts4920 Yes, you still need a baffle but what he is talking about is open baffle design. Easiest way to do is to just buy a large sheet of plywood, brace it and make a hole in the center. The cutoff frequency for cancellation is exactly the wavelength from the speaker to the nearest edge. 1m square should be enough, the larger you make it the lower it goes.
      And i for sure would like to hear the difference, open baffle is theoretically the best kind of cabinet as it has no backpressure and depending on the room, no dominant resonant frequencies that are the result of the cabinet having a finite space.. The downside is that the finite space of the cabinet improves efficiency but that is not a problem in a studio, you can have terrible efficiency, you can use a kilowatt to produce 5 watts worth of sound. But of course, the sound we are used to comes from traditional cabs so... we might get better sound in every metric, except one: nostalgia..

Could be my speakers or mix but honestly I am getting the idea that the only place it makes any difference is live in the room. If at all. I don't believe it makes enough difference to honestly matter in the long run as a signal chain can be manipulated in so many ways that I feel this just comes down to weight, cost, and preference ultimately.

    Thanks Glen, that was a really interesting experiment to follow.
    On a quick look at the relative stiffness ratings for the 3 materials, particleboard is the least stiff, then MDF then Ply.
    It kind of makes sense, particleboard has voids in it as it is made from many different sized bits of wood waste - from chips to dust. Strength and stiffness can vary along the sheet length.
    MDF is almost void free, but it tiny, unaligned fibres - so is known as amorphous or glassy in the materials science world. Almost the same strength in any direction.
    Ply can have more voids than MDF (based on quality grading) , but you can engineer in a lot of stiffness during the manufacture of it as well as prioritising stiffness in one direction over the other.
    So your comment on what the speakers have to push against is very relevant.
    Stiffer cab should mean less loss/greater efficiency - non-consistent voids in particleboard lead to losses and can introduce those off resonant frequencies.
    This may be different per cabinet based on construction and the particular piece of particleboard used.
    Additional bracing may help the particleboard cab to be better.

    Just getting around to watching these. I build my own cabs and have to say that even I was surprised by how subtle the difference was! The plywood has a little more 'woof' to my ear. I think that's because the plywood is more rigid. The mdf and particle board will absorb a little bit more energy through vibration and bass frequencies have the most energy.
    I should also mention that the alternating wood layers are making it more stable to humidity and temp changes. Plywood might last you longer if you are moving your cab around a lot or touring. Plywood generally has better screw tearout strength too, so handles, wheels, etc shouldn't pull out or get wobbly as quickly.

    GLEEEEEEEEEEEENN! Front loaded vs back loaded speakers in a 4x12 cab gives a volume of around three litres more air volume when the speakers are front loaded. I did those calculations like ten years back using the excellent free software WinISD which is a great tool when designing speakers. There are all kinds of funky parameters to tweak and it works both for hifi, lofi and nofi (read: guitar cabs) appliances. According to WinISD larger volume gives, not surprisingly, louder response in the lower frequency range. But when it comes to adding like three litres of volume to a 4x12 which already has like over 100 litres of volume you will probably not hear any or at best an utterly small difference.
    But in a recording situation front loaded speakers gives you more possibilities to mic up reeeeeeally close as it will allow the mic get closer to the speaker membrane by about an inch (if you have a grill/fabric in front of the speakers that is). And moving a mic back and forth an inch or so can make a huge difference in a record situation. I think front loaded speakers looks cooler as well. So for recording situations front loaded elements are better as they give more sonic possibilities. Plus that it looks cooler.
    Big kudos for your work, Glenn! 'Preciate it plenty! :)

    -Whether changing the height vs the width makes a difference (e.g. compare 1x1 to 1.5x0.5 to 0.5x1.5 (all arbitrary measurements) and see what changes) - Maybe see if recording a 2x12 on its side sounds different to one on the floor, does the floor affect resonance and tone? etc.
    -Difference in height / width change vs depth
    -Angled shape vs uniform shape
    I realise these would all be expensive to test, but it'd be great to nail down what really makes the changes.

    So build my next cab out of particle board and boost at 500 hz when EQing. Got it.
    I remember reading somewhere EVH solely used birch cabs. I wonder if there’s actually something to that.
    It makes sense though that the cab material would impact the sound. Frequencies would be bouncing off the sides and some would get absorbed or reflected differently than others

    I had two Peavey 112s. Both had G12H30's. One of them the baffle was destroyed by UPS in shipping. I replaced it with Birch and anchored the speaker the same as it was originally. There was a definite difference between the two cabs. Not better or worse, just different. I have used plenty of plywood and other types of cabs. The most interesting I had was a 112 that was completely plastic, like thick black stuff. It was heavy as hell and sounded great. The maker escapes me right now. Play what you like.

    You can get pressure treated mdf, it handles humidity with 0 problems. I have used it on speaker cabinets and subwoofers for HiFi and car audio for years, never going back to regular untreated mdf. What I can say from years of doing this is that volume of the enclosure is Key, and if you have a wented enclosure the shift in volume can be dramatic! I made a 2x15 cabinet inspired of the Old Randall cabs that Dimebag used, combined with a slightly deeper profile and two 6" aeroports, and that thing is like a possesed deamon screaming! I would just imagine that it is hard at best ro use for recording, but the unfiltered sound coming out of it is just insane.

    Best tip I ever got regarding cabinets was to make sure the I took the wheels off for recording, placing on hard ground, not carpet. And to loosen the screws a little on the back of the cab to get a little movement on the back to increase resonance.
    Gave a nice little woof, like you would hear on the palm mutes on the Justice album. Especially when just touching the string about 1/4 from the nut on the low E, while palm muting.

    I built some furnitures for my monitors last year half particle and part rral wood. I thought it would be very deaf but to my surprise it was too much resonant, noticeable while tiping with my fingers or knuckles. I had to modify it in different places, take away some parts, make some holes and add some holed pieces until I was satisfied with the resonance loss. The idea was I wanted the less resonance possible with the monitors. I also added some foam, rubber and eva for isolation.

    With proper bracing and construction they will sound very similar assuming same internal enclosure volume. If you read this Glenn, you should try adding some sound damping such as open cell egg crate foam or rockwool to the back and sides of the enclosure. This will have a much larger impact on the tone. If you want to know more about enclosure design I'm pretty well versed.
    Also not all plywood mdf or particle board are the same. Cabinet grade plywood is much better than what you find at most home stores. Plywood is used in speaker cabs for a couple of easons over mdf or particle board. Plywood is more rigid, lighter, and holds up to moisture and abuse much better than mdf or particle board.
    MDF is less resonant than plywood and that is why it is used in hifi speakers, but that comes at a cost of weight due to higher density. MDF will absorb moisture and fall apart so it is not good for gigging. Should be fine for a proper studio though.
    Stay away from particle board. It is garbage and should never be used for anything you want to last.

It's both lighter and more resistant to damage than either MDF or (shudder) particle board. Fortunately, my days of lugging big cabs are well behind me... a 1X12 is all I need to hear myself on stage.

    Dear Glenn: Re: your question at 8:57, this isn't a direct answer to your question, but your discussion made me realize it would be interesting to test with pure sinusoids. You'd then be able to easily hone in on where the weird rattling parasitic resonances are as you sweep the frequency. Admittedly pure sinusoids are not very metal. ;)
    Oh, wait a minute -- how about this: capture the impulse response of the cab, and then plot the spectrum of that impulse response using something like Audacity. The weird rattling probably is exhibiting some nonlinear behavior so it wouldn't be fully captured by a single impulse response, but it would start to get you in the ballpark of finding where the evil gremlins lie.

    I have a Heil 4/12 that I drive with a Fender Dual Showman. I put a mattress pad , foam pad shaped like egg cartons , on the inside of the cabinet . That tightened up the low end substantially. So installing a deadened on the inside of the cabinet will definitely affect the tone

  • @paulw.3967
    @paulw.3967 ปีที่แล้ว

    A simple way to find many serious resonances, rattles, and buzzes that doesn't require any extra equipment is to use a free tone generator (free app or website) with a very slow sinewave sweep up or down the audio spectrum, played loud. When you hear the sinewave sound being swallowed, or wobbling in volume, or sounding like a different waveform, you've got a resonance or a buzz or rattle. Sometimes you can hear a whistle or rushing sound of air going in and out of a small gap (or even a too-small bass port) when playing a low bass frequency. You want the sweep to be slow so that it's always playing a number of cycles at very close to each frequency, giving it time to tweak a resonance into exhibiting itself. Any anomaly you hear is probably also present in the music you listen to as well, when that frequency is present, but much harder to identify in a mix. You can also sometimes hear various things in the room rattle. Those things rattle while you listen to music, too.

  • @MojoStrummer

    So what you're looking for in terms of getting a full frequency image instead of real time is something called a Fourier Transform, I don't know of a program to do the analysis as the only time I've ever done it was with my own program that I made myself years ago, but you can run an audio file through it and it'll show the prevalence of each frequency across the board.

  •  2 ปีที่แล้ว

    Hi Glenn!
    I really like this series. The difference between the particle-board and the other two was even bigger than I had expected for a close miced cab. I would imagine there could be a more noticeable difference in the room-tone between mdf and plywood, if the walls of the cabinets vibrate enough. That might be an intersting experiment, even though not that relevant for redording metal, I guess. Knowing very little about recording I guess a back-mic isn't really a thing with closed cabs.
    Bracing to control weird plate-resonances should work quite well. Even an internal strut that gets wedged between front and back might make a difference. Worked for a subwoofer I built years ago. But there the main goal was to get the plate-resonance above the frequency of the low-pass. No idea about the effects in a full range cab. Bitumen-like dampening mats as used in hifi-speakers are an other solution that comes to mind.
    My prediction regarding front vs back loaded: virtually no difference with a close mic, in the room maybe a little different high-end, depending on listening position.

  • @mobbydysk

Ola Englund has video comparising different amp and cabinets and conclusion was that the real difference in sound is in the cab not amp but all those cabinets had the same speakers vintage 30 but the difference between Mesa cab to others was huge.

    Good job Glenn. My old shop had a vacuum table CNC milling machine. We had to mill the top and bottom of the MDF sacrifice board because it had a finish on it that air couldn't travel through. This got me thinking about how smooth or porous the wood is would change the sound. If you were to sand, paint or put adhesive vinyl on the inside of the cabs, what would that do to the sound. I know you might not want to go down this rabbit hole, but I thought it was worth mentioning.

    If you really want to go down an audio rabbit hole:
    Speaker Cabinet design.
    Bass reflex (Modern P.A. and some bass guitar cabs)
    Folded horn (older Sub woofers and some bass guitar cabs)
    W horn (Really old subs)
    Horn loaded (old p.a. mids/highs and some old guitar cabs)
    Down fired cabs.. this is used for mainly Sub woofers but I've done it with guitar cabinets as well. Place your cabinet about 1 foot off the ground and have the speaker FACE the ground.
    It sounds silly, but the reflection off the floor is actually mildly louder than facing out.
    This is a variation of something called Corner loading.
    Where you face the speaker into a corner and the reflection off the walls fill the room better than the speaker facing out.
    It's a very old (1960's/70s) era technique to get more volume out of the lower powered P.As at the time.
    Works with guitar cabs as well.

    As far as the cabs go the variation in size will change the sound fat more than the construction materials. However the construction material will make a huge difference in the cabinets durability over time. Pretty much the main difference between front loaded and rear loaded as far as I have ever been able to tell was the ease with which speaker changes could be made. Good video just proving that as far as sound is concerned the speaker is still the main marker of tone shift when a cabinet of the same dimensions is used

    I know this will not be practical in any way, but I came across a build guide for desktop speakers made from concrete a long time ago.
    The reasoning behind this was, that "the solidity of the concrete helps to eliminate natural resonance of the speaker enclosure, thus producing a more linear sound".
    Due to weight and fragility aspects, I don't think it would be a viable option as a build material, but I'd find it interesting if and how a guitar cabinet made of concrete would sound different than a cab made of plywood or MDF

    In the final analysis, the difference was a bit stronger than i thought but in line with my thinking: solid is solid and that is what you want in a cabinet.. or guitar.. or anything really, solid is the best companion for a moving mass that produces a sound, whether it is a transducer or a string.
    Now.. next one: damping material used inside the cabinet, yes or no.
    Then there is one test i've always wanted to do.. using full range hifi concentric speakers.... The problem of course is that full range needs at least two drivers and concentric design is still two-way. But, is the linear response what we want, or is there a built-in curve...

  • @weightofgold7420
    @weightofgold7420 2 ปีที่แล้ว

    The short answer: (re: front-loaded vs. rear-loaded) I decided on using a removable baffle because I have a diffuser built into my baffle. I also have front-reflex ports so that I can bolt (no screws or t-nuts) the baffle on tightly, by getting a wrench inside. I would advise that folks always use this bolting method even for removal of the rear of the cab in the case of rear-loaded speakers. Nothing worse than stripping those screws. An easy way is to make the bolts accessible is through handle ports on the side of the cab or a removable jack-plate. I also fixed the screen frames onto the baffle with Velcro so they can be smaller and don't have to be removed to remove the baffle. Also, If for some reason (and this sound like something Glenn would do) you wanted to try different baffle/diffuser configurations/materials, it would be a snap!
    The bolts are Phillips-head machine screws with massive washers (which are exposed and look cool/industrial). It's super easy to reach in and grab the nut/lock washer/big ass washer stack with just your fingers and remove the bolt with a screw gun. I had to do that a lot while in the construction/wiring/finishing stages.
