“I barely turned it up” “My sub ain’t subbin”

The owner of that sub musta had all knobs to the right😂

5:18 "rub here, rub here..." that is the same thing I told my wife last night.

Keep em coming bro. I always anticipate your next video. It's easier for me to send a link to your video rather than telling someone. Your willing to share knowledge is admirable

Wow... That owner really loves listening to the News.

That guy would have blown the sub no matter what box it was in. All you need is a little bit of common sense

He had the bass knob to 11😬

Steve Meade has badmouthed you before but I watch all your videos and you definitely know your stuff keep making videos I learn a lot more from you than I would ever learn from Steve Meade THANK YOU EMF CAR AUDIO.

I love Tuesday's now.

Very interesting stuff like your video I like the way you explain it in detail big thanks you thumbs up from me keep up the good work thanks KZfaq peace

For a too small enclosure, Scanspeak makes an Aperiodic Vent. Can you look into the effectiveness of such an item for car sub box use?

Great source of info and knowledge. Much appreciated.

Nice share and I agree with you on the leads. Clipping equals burning

This is not because the box is too big. Its because the owner had no self control LOL

Very informative video wish I would have seen it 3 weeks ago I recently blow a Sony gsw 121 simply because my box was 5x the size recommended by the manufacturer

Yup learned from a Zv4 4th order burned the leads right up at first I didnt understand clipping but now I do!4 good subs later.Good vid.that was extreme clipping for a min a burp.

CSI: blown sub division

This also goes to show WHY you NEVER want to run drivers like this in an open free air or infinite baffle mode.

Thanks for the very interesting video. It would help a lot to know the make/model of the subwoofer. I know it's the customer's fault, but what I want to do is check the numbers to find if I might have made the same mistake without knowing. Not that I'd be playing anything THAT loudly :D

Absolutely awesome information

I, too, like the sound of a huge sealed box. I just watch my power, and cone excursion, by making sure I have enough piston area to get the displacement I need, for how low, how loud. I very often only run a driver at 1/4 of it's wattage rating, because I run in compliance mode all the time.(well below free air resonance, where the driver impedance is essentially the DC resistance of the voice coil) I try my best, to cross over at a frequency, that avoids free air resonance, because the change in impedance creates a "hot spot" in the spectrum. I either like to run above or below free air resonance frequency, including the enclosure, which seems to raise it somewhat. If it raises it too much, I need a bigger box! When I'm choosing drivers, I need to know the X-max excursion, and effective piston diameter, because for every octave you drop in frequency, it requires twice the displacement. What it lacks in piston diameter, has to be made up for in excursion. Too big a piston, it's hard to get the pressure necessary, which means a larger enclosure. I prefer multiple 10's, 12"s or 15's at the biggest. If I need more displacement, I add drivers, which means more coils, more magnets, to create the sound pressure.

It’s all about the enclosure. 👍🏼

Lol I understand. It was probably one of the woofer flex friday videos!

Do you have any videos on how to build a box

The owner of that sub had the loudness on, bass boost up, bass to max on the deck lol

I bet that guy was bangin hard as f!!!!!

How big was the enclosure internally after all displacements of bracing port and woofer? And then also how many square inches of port area did the enclosure have?

Any suggestions on a 18 inch cerwin Vega in a rla type (w) tunnel bin ? I was told the larger the deeper?

I run 2 12" cerwin vegas in an efficient setup, each sub recommends 1.5cuft, I give them 2.3cuft each. however Im only giving them 600rms a piece instead of their rated 1200rms, because of the large box, I get maximum output and hit peak excursion with only half the power. works great.

My girlfriend's ex claimed her box was too big only to find out his Sub was too small 😋

Thanks for the info!

Totally accurate, ive seen subs blown more frequently in oversized enclosures

One thing I have experienced with a massive enclosure is that you reach the subs mechanical limits before the thermal and it will unload jump the gap and soon fail. But there are other variables that apply as well

How about doing a vid on what it looks like when someone hooks up only one coil on a sub?? And how important it is to hook them both up. I can’t tell u how many times I’ve redone stereos and one of the 2 coils is hooked up

I have a box that is like a inch bigger then spec play good but I notice the sub excursion high and when the trunk is open while playing it bottom out .does that mean the box is too big and if so will adding wood inside reduce the box size ? Thanks

When a subwoofer calls for a certain volume of box does it already calculate the displacement of the speaker or do you have to put that into the equation when building a box? J l audio calls for about .7 ft³ for a 10-in sealed box. But I'm not sure if the speaker displacement is already added into that. Most boxes I see are closer to one cubic foot. I'm having a hard time finding this information.

I have been curious about putting a sub in a box that is too small, its effects and how the power handling is affected.

he didnt use the proper oils,,,,only fully synthetic man !!! 5w/30

Emf audio I smash that sub button. Good to know. If my box is to big can I fill the space with egg carton foam.

how big should the box be for these two zv5 I have give me some measurements please

The "burnt" is from arcing. Not clipping.

Correction, when your amplifier isnt adjusted to fit your sub and box frequency responses and xmech :) Theres a reason for Subsonic filters.

I need some knowledge, what if the box is about 10cm bigger would that cause issues ?

I'm looking to put a svr-15d4 in a 4.3 cubic ft box. The specs suggest 3.2-3.5cubic ft. Does this sound like too much? I'm thinking you're generally good as long as you don't 1.5-2X the recommended air space

I didn't know you could blow a Sundown

Talk about tearing it up right..SMH 💀

Another excellent video .besides the enclosure been too big ,the port size is also a major issue .can you do a video on port ratio? Thanks again for the the info.

What about open baffle subs? Yes the cabinet can be a good spring for the sub bit it's really important to have a amp that can hold the sup in control also

All i know is if i had 2 of those subs they would last me a few years

He hacked his amp and tuned it to 100.000 watts rms @1ohm 😂

I know this,, but are u going to do product of factor equations for people who like to load/over load speakers ontop of speakers... do the math 1st AxB over A+B I USE n love the square4'cofig' on guitar stack cabs.. cheers speaker guy...

super nice educational right here boss thanks

Box size has nothing to do with anything except box rise . If that were the case they couldnt be in a ported or multiple order box ....this is a vlear case of too much power causeing clipping ....how the hell does box size have anything to do with coil rub lmao

3:03 JL Audio

i have a bass freq generator and my system shacks the truck at 1 hz i cant hear it but i feel it as it goes up in hz it gets audible around 20hz and from 21.5 to 31.5 it will do 150 db of bass. most burp test are done above sub level above 30 hz at 44hz and up

what happens if a sub box is .59 cubic ft to small for the sub because i cant find anything for a sub box being to small.

Confusing with some of his comments. Mixes his sentences too much. Did you really just say "A box that's too big will sound louder and cleaner if it's the correct size".... lmao 🤔🤔😂

Ive had plenty of boxes that were waaaay oversize and never had a problem.....not a single problem....i don't over power my subs tho. Ive got 2 15s in a 17cft box and i still hear them all day long amd they dont bottom out or anything.

Is there any way to tell if your sub is experiencing over excursion? Maybe the sub is moving too much but isn't bottoming out, can you hear it?any good way to measure it and make sure it's less than it's rated Xmax? Someone obviously looking to push their limits 😅🤷‍♂️

I learned this the hard way on an Old school JBL Gtx 450watt svc 4ohm sub. Blew the cone up and the spider got torn in a million places. Goodtimes tho i slapped harder than a 15 in that box 😂😂

It means build a better sub with tougher softparts or dont power it so much, if you hear your subs bottoming out then lower the volume. A subwoofer is at fault 1% of the time, and its not going to fail because the box is ( to big) it failed because of the owner

Dont believe the enclosure was too big bullshit. Some people love the lows especially sundown subs need a big box too unload on low frequencys. Thats was the cause of too much power. Plain and simple. If u make a smaller box. Ive seen alot of people blow there cone from too small box and have it try to unload. Dont over power and this wont be your problem

Good day guys, can you advise on what's the proper cubics recommended for a jl audio 12" w3v3 -2

Great info. I had no idea a box could be too big. I have two 12" hifonics subs rated at 600watts max each in a pretty big ported box. I recently connected a new 1200 watt Rockville amp and at first the subs were banging and handling the beat from the amp. Recently they seemed to be tapping out(wrong terminology, but I'm not sure how to word it right). Before they were banging just fine at the same volume. I thought they were in the process of blowing out due to excess power.....after watching this I'm wondering if my box is too big

Very informative, do you have a video on what happens to a subwoofer if the box is smaller then recommended and its sealed........ like when people put subs in a custom Fiberglass enclosure thats not made to specs? Like would it have any damage to the spider tearing off the voice coil or damaged voice coil etc. 😅

I just wanna know why the owner used such a big box. Was it a ported box that was tuned very, very low? At some point you have to realize that you're going to start loosing SPL and it's not efficient anymore.

what about the subs in an infinite baffle type setup?

thats why i like sundown. audiopipe and a few others out there that give you all the specs and box sizes on paper so this dont happen..but still this guy beat on that thing bad,,,,,,, good video and education

I bought a Avatar STU 1246 subwoofer & a Ground Shaker 2.70" cft 30hz "Competition" enclosure. The plan is to supply the Sub with close to its RMS of 3000watts. The Website said the STU's can run in a 1.94cft box but every setup ive seen they were running 2.25-2.60cft box. Might the 2.70 be too big for the Avatar?? Even though i got it at half the Price Brand New, i still wouldn't wanna blow rhe Sub. I also will be breaking the Sub in slowly on 1200watts for a few months as i do all my subs. Any suggestions would be greatly appreciated & thanks

Is my box too big ? I have a jbl s2-1224 on a 3.5 cubic feet box ported box The recommended size is 2.5 I barely feel any air coming out from the port My vent length is 13 inch long and 2 inch deep Is the port too small ?

Question I have a ds-1812 that's rated 2000 RMS I only have like $700 RMS going to it and it's just flexing alot and sounds like air not bass I think that means my port is too big or does that mean it's too small cuz I'm watching the sub flex to its Max

My sundown sub is brand new and is very stiff, is that normal?

If box is bigger is needed more port area?

nice video!! and nice explenation ! thanx

Great video very educating it's sad to see a nice expensive sub like that and be destroyed to people's lack of ignorance that's why they give you a spec on the sub and for the Box

Do you have subs that perform well in small boxes..12"

Can you make a video on boxes that are too small?

When you see enclosure ratings for subs and want to use multiple subs, do you double the volume? I see many professional setups with 4 15's, 4 12's ect but they don't have 14cu.ft. enclosures. Is there I simple way to understand or calculate this? I would love to have 2 x 15's but just don't have the trunk space.

Thanks. Great Video. Very educational. I believe you were playing around with a 18 inch version of an EMF Banhammer Sub a while ago. Any future chance on a 18" lowballer?

Any vid of modified 8" beast sub

Great video

Rubber suroundings are stronger and last way way longer. But am preaty sure companies know what there doing...... Thanks for sharing.

Is there anyway to mitigate sub damage by adjusting the port? Ive designed a box that is 2.9 where the sub is recommended for 1.5. idk how im going to fill in certain areas to take up space or maybe block off certain areas

What happens ig the box is too small?

If I have a 12” scar what’s the minimum width the box can be? (I have 17 inches max width to fit the sub, can it work in a small size and how long should it be?

I've only went 1/2cube to 3/4 cube at MOST larger But damn.. Triple the size.. What'd he have a 7cube box? My sub calls for 2cube ported.. I have it in roughly 2.48cube net.. I stick with RMS power or slightly under also Rated for 1000rms.. I've clamped 790rms thru a range of frequencies

Bro I have a Dayton Max X in a 2.5 cu ft ported enclosure tuned to 32 hz. The box was built for this exact sundown sub. I need a budget sub under 200 for this large enclosure.

From my understanding, this can also happen if you have a vented box and are playing well under tuning without a subsonic filter. Just heads up for others that might not know.

Will you touch on the issues with a box that is too small?

Generally, if the box is to big, you'll lose dB's but have extended low frequency, with lots of over travel (excursion). The roll-off will for instance drop from 35Hz to 25Hz but you can easily lose 6dB at 40Hz. The big box will most likely have much more output below 20Hz, if you are willing to drop the volume to limit excursion. The bass will have much less punch and definition but sound more like a distant rumble.

Well,if the manufacturer doesn't give out box specs? What is the correct box for the sub then? Should I refer to the sub vas value?

Thx.

If I stay within the manufacturers recommend box limits it should be good?

What if my box enclosure is .25 cubic feet bigger than the max recommended size for the sub I have? 12" kicker CompC 300w rms @4ohms in 2.5cu ft tuned @34hz? Thanks for the information in all your videos. 👊👑

My suspension on my zv5 10 is like five times stiffer than that I couldn't push mine an inch in nor an inch out and I have looser suspension than stock

will that happen if the box is slightly too small? like off a couple inches.

do you have any video of box that is too big for the sub? In over words are you saying he was pushing it too hard because of the over size box?

What happens if the box is too small

I was hoping you would actually put and play the sub in an appropriate size enclosure vs one thats too big so we could see and hear what happens

So just some random input over here, hard braking can also cause your voice coil to ‘wobble’ enough to rub. I’ve been driving listening bumping it close to its limit and had to brake hard and heard it rub. (Sub is EVL18 on 1500w (ported) and in hatch facing up and towards back window at a slight angle.) When I noticed it first I thought it was clipping but I believe it was rubbing. It’s very nerve racking and sounds awful when it happens so every time I come to a stop I have got into the habit of knobbing down a bit. So much so that I reached for my bass knob when I was driving my moms car to SC (as well as a clutch pedal that wasn’t there. Many times) 😂
