    I think the subwoofer crawl was more in mind for people who was just getting in to subwoofers and using smaller entry level subs. Also this has been around long before REW and similar were readily available. It’s a simple way for the average person to get in a position that might be better than where they may place it ascetically

    With the crawl your meant to use bass sweeps not content to get an idea across the frequencies. Using that solves one of your 5. Measuring is great but it comes at a cost and a massive time committment if you have lots of options. I wouldn't put people off it, as it's a great starter way for your average person with one sub and just got into the hobby, as for them a measurement mics would be a significant additional cost for them. But as you state diagonal opposite corners will work most of the time, assuming the room is a rectangle and you can afford 2 subs.

    Not exactly. The crawl can help you quickly identify a potential good location for subs in relation to seating locations. Yes , measuring ultimately gets you more information but it's mostly still never going to be perfect from all seating locations, where as peaks can be knocked down with EQ. You can anyways use a smaller sub for testing locations if necessar.. I say don't automatically discredit the crawl! It's a good searching method if not finalizing procedure

    Just to let you know, I have used the audyssey Mic for the Denon receiver with Rew. Not exactly sure how accurate it is, would be interesting if you could do a video with REW and use an audyssey Mic versus your calibrated Mic to see what the difference is. I have dual subs one sealed, one ported. I use Audyssey to EQ the dual subwoofers, but after using REW, I realized time alignment was off. I ended up switching my subwoofer distances on my Denon AVR little by little using REW. Now I have plus or minus 3dB from 18Hz to 80Hz. Bass is a lot better now. Thanks for your videos.

  • @grandpixel
    @grandpixel 7 месяцев назад +2

    I have to disagree with your conclusion and your reasons.
    1. You don't have to use the same subwoofer for the crawl that you'll be using for listening. Yes it needs to play nearly as deep in order to measure those frequencies, but you are largely (ha) measuring the room and not the subwoofer. So take a sub that fits in the chair, and measure. Also I might add, setting up a theater is a ton of work in the first place, so I don't really see moving a chair as a big deal.
    2. It's not subjective if you are measuring and using REW. I would never crawl around the room and listen by ear. You're right, that's pointless, but that doesn't mean the subwoofer crawl doesn't work well. Use a mic and measure.
    3. See 2.
    4. Measure each position and use MSO software. It will tell you the best combination of sub positions AND delay for each sub.
    5. :\

    • @Youthman
      @Youthman  7 месяцев назад +1

      If someone is willing to use the subwoofer crawl in combination with measurements, I’m all for that. But most that teach the subwoofer crawl do not mention anything about taking measurements. That’s what I find is flawed.

  • @andrewrobinsonreviews
    @andrewrobinsonreviews Год назад +5

    Michael, great and informative video, but I think you're downplaying how the "crawl" is meant as a starting point and not as the end all be all. First off, not every room has four walls or is symmetrical like the diagrams you show from GIK Acoustics, which in turn means that users will have to get more creative as it relates to placement. But I'm getting ahead of myself.
    To your first point, just because a subwoofer is heavy doesn't negate the effectiveness of placing it in your primary listening area and walking your room (you don't have to literally crawl). Sure, it's inconvenient and may keep folks from doing the crawl, but it would work the same as if your sub is smaller or more manageable.
    Your second point about the crawl being subjective isn't wrong either, but that doesn't mean it can't be a good starting point. I too promote setting up your subs using measurements in the end, but the whole point of the "crawl" is to find a handful of suitable starting points to then drill down your setup and your settings --not to set it and forget it. Again, with irregular rooms, placement can vary wildly. For example, two of the "best" locations for subwoofers (according to this video and examples) in MY room are two of the worst --truly. In those locations I have dips in my bass response deeper than the Mariana's trench. But doing the "crawl" when I moved to my new home helped me to locate two or three additional spots in my room that could work, wouldn't you know it, subjective as it may have been, two of the three are pretty ideal. I later confirmed them with measurements.
    Your third point about frequency response or the frequency response of your main speakers is pretty much it's own video and honestly has nothing to do with subwoofers or their placement because you should get that right first before worrying at all about bass. In my room, my left speaker has a sizable dip right at 40Hz (assuming the speaker can play that low). I have learned to work around this dip by feathering in my subs to cover for it. I leave my left speaker in that space, because from 40Hz on up, most speakers measure linear in that spot --but I know this because I measured dozens of positions in my room prior to settling on the layout of my speakers and furniture.
    The fourth point having to do with multiple subs isn't quite accurate either --especially if you have an irregular room. Because doing the crawl may allow you to locate multiple locations with which to at least start from. One cannot make the assumption that everyone's room is symmetrical. Again, not saying the crawl is a set it and forget it solution, but it's a jumping off point that is free to try and when used in conjunction with auto room correction like Audyssey or DIRAC can be enough for most people.
    As for the last point about looking silly...everything about this hobby to a certain extent is silly. The fact that two grown men can playfully argue over the "best" way to setup or place a subwoofer is, by its very nature silly 😉. But the threat or promise of looking like an idiot shouldn't put someone off trying a technique that can honestly work as a jumping off point.
    As for the measurement tools and methods, that's all something people should do, but I don't think it's a one solution fits all situation to shame the "crawl" when it can actually be helpful as a general jumping off point. Just my 2 cents. Keep up the great work, always look forward to your videos.
    Regards,
    Andrew

    • @patrickmoodley6619
      @patrickmoodley6619 Год назад +3

      Well said, Andrew. Would like to add that the sub crawl works best to narrow down the placement in a single sub setup from a handful of possible positions where you can physically place your subwoofer in your HT space and is not meant for situations where you have multiple subs.
      It is also ideal to make use of a frequency sweep instead of music as what you are wanting to hear is an even response when doing the crawl and music with only a few low frequency notes would not be able to do that.
      Enjoy watching both your channels, keep it up.

    • @Youthman
      @Youthman  Год назад +1

      Hey Andrew,
      The crawl might be a good starting point, but most online publications, Facebook groups and forums put a lot of emphasis on the sub crawl and make it sound like that's all you need. That's simply not accurate and the video is an attempt to share that there is a much better way to achieve a smooth bass response.
      You mention the sub crawl isn't really a crawl, yet even well established sub manufacturers state and online publications promote the opposite.
      "Keep your head at/near knee level while listening (hence the term ‘subwoofer crawl’)" - SVS
      "Now get on your hands and knees and pay homage to the subwoofer (just kidding). Seriously, for the next part of this set-up, prepare to do some crawling (this is the part that could get you committed, but its all worth it!)" - Audioholics
      "Crawl around in places where you are able to place the subwoofer, and find the location where the sound has no audible volume boosts or dips. " - AV Gadgets
      Regarding subwoofer weight, it's the difficulty of moving it around (I do that anyways). Many of my subscribers (including me) have massively large subwoofers that physically do not fit in a seat. In my case, I would need to disassemble my theater seats (which is not practical.
      I agree the sub crawl could be a descent starting point. My main concern is this is not what is being conveyed online. It's inferred that "this is enough" which is not true if you are looking to get the most out your subwoofers.
      The point of the video is not to "shame the crawl" but to merely point out that it has many flaws and provide a better solution.
      At the end of the day, we all choose what we feel works best for our own setup.
      Some use room correction to set levels, while others use their ear, an SPL meter app on their phone, a dedicated SPL meter or a calibrated mic and REW. There's never "the only way", I'm simply stating the sub crawl isn't as amazing as many claim it to be.
      Have a blessed week

    @KidHorn7001 23 часа назад

    I've done the subwoofer crawl and much of what he said is valid. It's never clear which spot sounds the best. And there are only so many possible placements that don't produce a dangerous or awkward location. Better to put the sub in the few possible locations to hear what sounds best. The best thing is to get multiple subs, a mini dsp, and figure out how to use REW.

    Hey there Michael, I have the Martin Logan Dynamo 1600X with the Anthem room correction paired with the Classic 9 ESLs. THAT made it SO easy. I had a big peak at 25 HZ. at the listening post in my 18x24' space.
    After ARC (from a minimum of 5 listening positions - you can go up to TEN!), the display showed the huge improvement! 25Hz, was leveled, and the range was extended to 15Hz.
    It is so cool plugging the laptop INTO the subwoofer directly when finished it sends that data to the sub and also does occasional firmware upgrades this way as well.
    You can switch ARC in and out on the fly from your device and hear the differences instantly. Can't say enough about how easy and effect this procedure is.
    Well, that is my experience with the Martin Logan/Anthem joint effort which is also found in their larger Estats as well.

    I think when you have got to the level of home cinema as you have, you do not need to worry about subwoofer placement given the setup you have. You ain't gonna find a better more convenient place for your subs liekwhere you already have them. Can't say I have ever heard of the crawl method, but considering I have a living room setup with a single 10-inch sub, I might give it a go.

    The reason sub crawl is bull shit is because the sound that propagates from the sub in your listening position will not be 1:1 when you place it in the "sweet spot" location, that's just not how sound works. If you discover your "sweet spot" is the corner of the room, what the hell makes anyone think the sound waves emitting from the center of your room will respond the same way when placed between two walls? THIS is the reason sub crawl is nonsense.

    That crawl is intended for music listeners not home theater. The types of listening conditions are different. Music is lively with the room and type of speakers for image. Theater room is more favored under controlled environments and is geared toward impact more than realistic lively image with placement that is subtle for constant listening as opposed to sporadic sounds that are occasional. Therefore that method is a start under practical conditions, but was not intended really for home theater. Home theater is more calculated for consistensy from home thearter to home theater ideally calibrating close to even levels/standards speaker to speaker. Music listening is more a feel, based off of what the room is giving similar to a music hall, arena club, etc. It's there to compliment what is being provided. Therefore caters a little more for enjoyment and favoring tweaks that are pleasing to the ear. The conditions change and are not absolute like in a movie theater. Therefore the set up should be handled differently. Although there are some parallels, you can't expect to have or use the same calibration for different conditions just because it's involving speakers. Hence why THX systems were great as they were not ideal for music, nor is it set up the same as music systems. They are great in their own lane, but require differnt rules/ methods of set up for differnt purposes. You will need some common ground to make a living room suitable for each purpose of listening to music and enjoying movies. One method/way may seem silly or useless for the other, but maybe a part of what makes or breaks the other.

    if you look at the a software read out to think you have the right setting then you accept it right, going by the readings. when its all about how it sounds and your ears do that, some people like boomy bass some like crisp bass and some like it thumping in you chest bass, so its up to you to your hearing how you set your system up.

    • @Youthman

      There are definitely preferences when it comes to the amount of bass that we prefer, but having peaks and nulls in your response is not good for anyone’s preference. I’m not sure what crisp bass sounds like.

    You are correct, but the most important reason is that the subwoofer interacts with the room. Placing the sub against a wall or in corner will boost the volume, moving the sub to the left or the right of the main speaker can have significant effect on peaks and nulls. In summery, placing the sub in the main seating position will not sound the same as placing it in the place where it sound best when you crawl. The correct way is to fiscally move the sub, measure with a calibrated mic in the main listening position using REW. Having said that, in most cases the best position to put the sub is not always feasible, but you can try different feasible locations and choose the best.

  • @turboboost99
    @turboboost99 9 месяцев назад

    What practically everyone (it seems) doesn't understand is that you have to take HEIGHT considerations into account when doing the subwoofer crawl. That is another reason it never works well. You can't simply plop your sub in your listening chair -- you have to place it AT EAR HEIGHT. Inches matter! Room modes are 3-dimensional, not 2-D, and height modes are just as problematic as length and width modes. Accordingly, you need to realize that optimal subwoofer placement, regardless of whether you use measurements or your ears, may require elevating your subs off the floor, perhaps even several feet. The flattest response may actually be hanging your sub 3 feet over your head, which of course is impractical for most people. The point is, don't make the mistake of assuming that placing your sub on the floor is the only option. For more info on room modes, which are in 3 dimensions, not 2, read the works of the world's foremost expert on psychoacoustics, Dr. Floyd Toole.

  • @Hal2audio
    @Hal2audio Год назад

    While some of your views have merit,I feel you are discounting the benefits of the crawl. First of all most people do not have the monster size subs that you have and thus easier to place in the sitting position. 2) people will usually listen to many ranges of music/ movies scenes that allowing for multiple freq to be heard . My first experience with placing a sub was terrible I thought the sub was broken. As a novice I found the concept very helpful in hearing what the sub effect were in different positions.

  • @markroles7304

  • @bigchimpin4215
    @bigchimpin4215 Год назад

    The sub crawl is for sure rudimentary, but I don’t really think it’s for folks who are putting thousands of dollars into their subs. At that point the people in question should have already invested in a calibrated microphone and a software of their choosing. This is especially important with higher outputs because of how much the lower ranges interact with the listening space.
    If you’re the average joe who just bought a budget minded 12 inch I think it’s okay recommend the sub crawl. No sense in spending money on a mic and software that costs more than your sub. If someone were to have a 1000 dollar subwoofer budget I’d wholly recommend them buying the best sub they can for the money and using the sub crawl as their placement guide instead of spending money on equipment for measurements.

  • @ziqfriq
    @ziqfriq Год назад

    Sure, using your ears alone on program material or single tones is not likely to result in the optimum overall setup. But it's not a case of either-or. The reciprocity trick still works. You can put your sub at your listening position and move your calibration microphone around the room. If your sub is big and heavy, it's all the more convenient. It may be inconvenient to elevate the sub to ear level at your listening position, but you can compensate by having the microphone at ear level, instead of crawling on the floor with it. If you're a super HT geek like Youthman and have theater seats bolted to your floor then, OK, it may be more trouble than it's worth. But if you have just a living room setup like me the reciprocity trick works fine. I just have to move the sofa out of the way and put the sub there.

  • @TestTypeG
    @TestTypeG Год назад

    Completely agree. I always say that if you don't do measurements with a mic, you are completely blind in what you are doing when it comes to a sub. Doing a sub crawl is bad advice, you have no way of knowing what the frequency response is with just your ears. Taking measurements is the only way to do it. It's really not that expensive to buy a UMIK-1.

    I personally in my opinion solved all these problems. I just placing my subwoofer directly behind my chair now I understand not everyone can do this.

It is a smaller bedroom and I never had a problem with the deep deep base what I did have a problem was anything around 60 Hz or higher Now I no longer have those problems in my opinion placing it near field kind of gets rid of the room problem. The room has less effect on the overall output now like I said, I know everyone cannot do this and I completely understand but this has been my experience.

  • @rayking507
