I think he actually made a design himself, either way, this is cool as hell! First time in many years im excited to watch something on youtube! Keep it up Sam!
@crttechs873 If he didnt watch it yet he will because I already asked him what he thought about making a design for this in his next q&a on patreon 🔊🔊🔊🔊
It's his meat and potatoes, would be great if he joined in with a design. With Barevids we can all give it a go, pros, armchair know it alls and keyboard wariors. Fair contest and good clean fun. I'm not scared, your scared :D. Bass fest, we all want nice bass. Bring it on :D
@@UberAlphaSirus He mainly engineers with AD designs and Audio dynamics so his meat and potatoes is in Sq but im still dyin to see one of his creations in Sam's test cabin lol
@@atticchopshop8180 the first lot of designs are SQ. I have a screaming nasty burper in design right now. Dunno if Im going to do the SQ. Might do if I can send in my filter with it. We will see
I could not stop laughing at the slowed footage of the 2" woofer. Dearly love the idea of a 2" woofer raising the roof, like something out of a Looney Tunes cartoon. 🤣 Good start! Definitely keep the test jig as it is. 👍
I can’t for the life of me understand why this channel isn’t at 10x the subs. Too bad the first song doesn’t sound like this in real life. What a bass line!
You have had some of my favorite car audio related videos. The Digital designs VS. SUNDOWN, The mini boombox, the amplifier upgrade, how a hifinoics amp works, t line door cards
Absolutely awesome. Been looking for some scaled-down testing of subwoofer enclosures. We all definitely need to see a lot more enclosure designs demonstrated. Thanks
Trying to plan together a season 2, it's a bit tricky as season 1 netted me a loss so need to reconfigure some things to make it viable, even if it just breaks even
For my Subaru, with the cabin sealed, it’s a 48HZ cabin with the W7. Front windows open, 20-28hz, and with all windows down, 31-38HZ. Call it the poor man 6th Order Bandpass. If your enclosure is vented of course.
I have been catching various bits and pieces of this series.Not sure if you had planned to do this, but when it's over, you should build a full scale version of the loudest and second loudest one, and see how they compare. Versus the miniature.
Wow, the real world application of this is so well done! It all works out perfectly and even the mics distortion sounds like in normal bass demos. I can't wait to see what kinds of whacky enclosures we'll see!
This is actually awesome and I can see this being useful for testing strategies to make stuff louder without having to build the whole thing beforehand. This is a fun way of experimenting, I was impressed by the air movement of this thing. It's so cool!
Dude I’ve been so excited for this series after you announced it. I was thinking you were going to do something different, like full scale, but this is awesome i have to say.
I've been watching for well over a decade. You always come up with creative ideas for your videos. You deserve more views surely. Nice work, tuned in as usual! 👍
Try this - put the pic inside the enclosure and use REW to measure the response to sine sweep starting from below the box resonance frequency. Look at what REW is reporting for THD. Increase the power for each sine sweep until the THD hits say 20% in the passband. That will give a really good idea of what to expect when the design is scaled up...
Lol we don’t need a cookie cutter brown box tuned at 33hz. The man doesn’t build good boxes. He uses a standard method that any c grade audio shop would use. That’s why you never see his boxes on demo videos from random audio shows unless you search his name.
That Box reminds me of those little tents at the sports good store. Those little tents the models on the shelf. Always wanted those for my GI Joe and he man. But you could be designing rooms by testing that scale room. You could be a builder for expensive rooms.
What's interesting is the science and testing that you are doing is also relative for the microwave energy. Not only can we specify and test for Power at a point and decibels... But we can learn how to cancel frequencies and that will be the magic shield of the future.
This is pretty fantastic. I love this project. maybe I'll submit something. my subwoofer design is pretty limited to winISD with a crude approximation of cabin gain, rather than properly considering helmholtz resonance and standing waves.
This is like another series I like on TH-cam called Fan Showdown. He tests user submitted PC fan designs and compares them to a quality aftermarket one.
So, I want to make my own TV stand with a subwoofer and components. But what I am looking for is the absolute best sounding bass, as low as possible for the subwoofer but not sacrificing too much range. I like the deep rumble for movies. The subwoofer I'm thinking about using is a 8" Sony. It's currently in a powered cabinet, but it has the two plastic ports like 1" in diameter and about 2" long. I'm hoping a custom box might give it something a little better for down low. What enclosure would you recommend best? T-line? Sealed? Or a ported of a variant? I know sealed is great, maybe a little larger to allow for it to flex easier, but I also know free air is also supposed to have great range without box influence. I know t-line can make a sub louder with less, but then so can some ported. I plan on also combining it with a 4" to put under the seat for a little feel and kick. The 4" is decent in range when I plugged the port and made it sealed. The 4" is an Altec Lansing. I know the opposite would be best, but I don't have the space to fix the 8" under the seat. I was also thinking about a down firing ported or sealed with the components on the sides and maybe a center speaker as well. What do you think?
Hello Sir i have talked to you before on some different amplifiers and was wondering if you had ever used the MMATS Pro Audio amplifiers was looking at the m2000.1 instead of doing Digital Designs M2500 amp on two 2508 in a 6th order bandpass any information would be greatly appreciated . Thank you for your time.
When you measure the FR of the box I'd recommend to move the mic as close as possible (1 cm) to the source and measure the driver and port separately. In REW you can sum the two responses and the result will likely match very well with your simulation
You can also do the "transfer function" approach to remove the "room" from the measured frequency response. The approach is similar to measuring cabin gain, except now you're going to use the measurements to use REW to remove the "cabin gain" (room effect) from the measured response to obtain a simulated anechoic response.
I would like to ask a question brother. I have two matching alpine 500.1 amplifiers and would like to know how much you charge to repair them? I'm from the US.
If you placed an circuit that would limit the power at 15W. That would make it where you would not need to watch the power meter. If you know a little about Shell, you can setup a simple script. Place a camera on the power meter, where you can add it in the postproduction. You would only need to turn it up then back down. If you was to write a script, it would be able to roll the volume up, then down, with the same velocity every time, and you would need to only press one button, unless you needed to abort. The script could also be set to recognize, when you get to mechanical limits. That means that you could set a limits to where you would be within a certain safety factor that would allow for the actual mechanical limits not to be exceeded, and then every run would be maxed out, with the furtherest possible limit without leaving out of the clean outcome (hopefully that makes sense.). You could also place a red light near the power meter, which would be lit incase mechanical limits were reached, and then a second light would indicate a run up to the max power. This is crazy. I understand that it is only maths. But still. Keep them coming.
Awesome new series Sam and loved hearing 'Bass I Love you'. I wasn't keen on the annoying crowd noises from 15:40 onwards though, really distracting unfortunately 👍🏻
Shrink it 10% and make the port 10% smaller and same length (No fancy software sorry) I feel that will help loading and tuning farther away from cabin resonance for better bandwidth
Damn happy I havent got my 15"s towers on this,you know the ones. 25hz would have caused a cave in. If you know anyone, they are still ready to go to a good home to anyone that can pick up in south london. This Kef 10" is rocking these tones down to 30hz.
I was wondering since you do so many repairs , would you say a burn or damage voice coil on a subwoofer hooked to a car bass amp eventually internally damage the amp ? Or that is impossible , will or could there be a way to know if a sub is already bad ?
@@charlschuck6 if the sub is disconnected and not moving the ohm reading should be stable. touch the meter wires together tho to make sure it's stable just on the wires.
Hey Sam I started designing an enclosure but it will be quite large. I will test print myself first it is a compound folded horn paraflex enclosure. Might have bitten off more than I can chew 🤣
Something like this th-cam.com/video/KRdBzvFJtY4/w-d-xo.html ? or th-cam.com/video/7LS-UismSJc/w-d-xo.html they're for 18's but I think they scaled down
So, already loving the hell out of this, but, for the second season and in the future, there should be a generic model of a car, preferably with real materials used in cars so the scaling would be as close to what it could be in real life, meaning something like ; 4 doors, rubber seals, scaled thickness of metal of the chassis, interior damping and isolation, vents and other stuff that makes a car, with 3d printing, it should be possible, this would take it to outerspace type of quality! As you mentioned, as it is now, its a fully prepped spl cabin with basically no leaks anywhere, but thats a really small percentage of real world uses, it all reminds me of a video of veritasium i watched recently with scaled boats and the biggest controlled wave maker, same idea as this one! Make a scale model in a scale environment and Take the video slowed down by a considerable margin until it fits real world scenarios, it was unbelievably real how it turned out, and to think, its also fluid dynamics! Water is fluid!
Is there a party going on outside where you live or is that noise added? I can't wait for the rest of this. You can test materials and construction methods too.
I added some crowd background noise to make it feel like a car audio show cos it felt kinda empty with silence but maybe I will leave it out next time 😂
I have an idea for a box mount the speaker up inside it in the smaller section facing down towards an open bottom with a rear facing slot port tuned to 65 maybe like 1.6:1 idk about bandwidth
Hey when measuring real music are you playing it at 6x speed & slowing it down in post to bring it back to what people would say is comparable scaled up? --> Never mind. Just hit that spot. Good foresight!

This is awesome. I think if you keep at it long enough there could actually be a major breakthrough that gets very popular in full scale builds.
Wonder what 6 or 8 of these would sound like lol I love this series
My $7 dollar bkuetooth speaker played excellent through all frequencies. Ummm. I love youtube. No mention of woofer chosen.
Try this - put the pic inside the enclosure and use REW to measure the response to sine sweep starting from below the box resonance frequency. Look at what REW is reporting for THD.

Need those little trolls with the fuzzy hair. Does it hair trick for some fun bonus footage.
So how did you get passed the spl lab frequency limit? I kinda want to play with this on my own for testing purposes.
I'm currios what will perform better. 4th or 6th order
Build a fan subwoofer, some examples here on TH-cam but none for automotive
This is gonna be a great series. What's the cheering in the background, copyright noise I'm guessing.

A damaged coil can kill an amp yes, if the coil is shorted and low impedance. You can check the ohm of the coil with a multimeter
