Try fitting in with some cheap prs instead of drivers for experimental. It might have more punch than normal prs? I dunno.... lets try that out. 👍
I have ordered a couple PRs and they both don't fit. I'm still looking tho' if I find ones that fit perfectly, I will come back and report with a video, I'm loving these experiments 😂
@@DLXWillington Yeah me too.... loving these experiments too. Some time later if you couldn't find any prs, then diy is your answer.😂👍
Can u add air inside the pr to make a speaker have more bass
@@rawwdyrichh3741 air inside a pr? How? With a compressor?
Keep pushing!
What about upgrading the existing speaker w a coaxial race track driver for better highs???
Before:best bass
After: not so good bass
YUP!
@@DLXWillington Is it sealed well, and are all of the drivers in phase?
Not it's because there's no prs 😂
@@jblfamily02 you really don't know any about sound physics, do you? 😒
@@derSkedda the speakers are just fighting each other which makes the bass kinda shitty
The original sounds better... the passive radiator gives better bass pump than putting regular speakers
VoV
it louder, but the original has deeper bass
Tru Dat 👍
@@DLXWillington hmm, if do put little port on back it maybe increase the bass
@@villepekkala Yap port could help in this case but bigger enclosure too😅😅
Bass better song
@@villepekkala port will not help. The enclosure already is yoo small
- Carefully. When you connect 3 Drivers to each other in a parallel order, the final impedance decreases radically. If you use the modified Charge 4 at high volume for longer time you can kill (burn) its amplifier. - You lost bass, because the box space decreased behind the driver when you replaced the Radiators with fixed drivers (and those also require box space).
Yeah cause the box is sealed too so the bass lowers
The speakers need to be wired up in series. By wiring them in parallel, your lowering the ohms, increasing stress on the amp, and increasing the low end filter with the lower ohms. It would work best if the side speakers had twice the impedance of the original; so that, they could be wired in parallel with the intent of replacing the original driver. I guess in the end, more research could have made your first try so much better. Thumbs up for entertainment!
Wouldn't each speaker in the series become quieter and quieter because of the voltage drop?
@@elephant1851 That's why he said it sounds loud now. It was designed to work this way.
and it's more complicated because C4 transducer is 3 ohm, each F4 is 4 ohm, so if you put all three in parallel results in 1,2 ohm
Not series, series parallel
This guy didn't even know what aluminum tuning weights were on the PRs.. I doubt he knows ohms law or parallel vs.. series. These are quarky ideas at best with no real understanding.
You could improve the bass if you hooked the new drivers up, out of phase with the big single driver.
Just switch the polarity from + to - so that when the big driver pushes out, the smaller drivers are pulled in, and when the big driver is pulled in, the smaller drivers are pushed out.
Right now they are all fighting each other to compress the air inside the unit.
This is quite interesting, it might with trying out 👍
True
my first thought.
@@DLXWillington I did the same thing to a stereo blue tooth unit. I removed the passive radiators and replaced them with drivers wired out of phase. It dramatically improved overall sound quality.
I would not suggest that cause they'll cancel each other out. What you have now is seald box. Changing polarity in this way is like plunging 2 different speakers out of phase and waiting for good results, but in realty they're gonna cancel each other out. Just look at bass driver, it needs enclosure cause there are 2 sides of speaker and without shaping the phase with box one side will cancel out the other.
2:55 😂😂 my favorite part
Great work mate, people are still reviewing things on there youtube channels but here you are with new ideas and videos which are entertaining and informative at same time and interesting to watch...
Thanks man, for putting my comment in the video, I appreciate that.
nice work dude! cool 3d printing
🥳 Congratulations to 40K 🥂
I love ur vids man! im subs for years on this channel i think :)
Thank you so much for video it was fine!
Legit was just thinking about me doing that on my charge 4 and then I see this pop up in my feed
Before the sound test, I thought the charge 4 modified will cut the bass and the loudness but after I was impressed for the loudness. I think you could put passive radiators on the front and back and the charge 4 modified is going to be better than the original.
Good video and keep up with the good work
It's out of phase, it could work if the polarity for speakers on sides is reversed to stock one!
Try this out again, it should change the sound if you do that
the modified one has more treble and not enough bass but sounds louder
Yea cause the flip 4 drivers have no bass
DJekrom no you can find an e planari in in physics
@@fantaseditings3017 what is an e planari?
Nope, he didn’t wire the speakers out of phase, so every 3 speakers are fighting on pressure...
@@djekrom3286 you mean flip 1
It's like you went I my brain I was thinking about that for years
Maybe I went into your brain 🤔🤣
When he did that sneeze that’s what she said thing I subbed right away I laughed so hard
🤣
I would assume that with the modified one, though, it won't sound good since air can't get out and move. It will compress inside and not allow the speakers to move as much, right?
Very hard-work
Before : good bass but kinda quite
After : loud AF but less bass
Huge difference 🔥🔥
I fully agree with you about the sound
Came here from the video where you "killed" the PR's in the charge 4. And while you might have an accent, I was impressed how good everything looked in your place, and the video itself as well. And although you'd been better off watching a YT video showing how to disassemble the radiators without damage before you started, it was still an entertaining video to watch. But please wear protective eyewear when you do crazy experiments like that. No amount of views, trumps damaging your eyes.
Excellent job dude, i have an jbl charge 3 that got wet inside, I recycle the battery, but with this know I can recycle the speakers and put them into another jbk
the drivers in there are quite a bit big but they might fit into an Xtreme. Good luck
It got wet and you recycle the battery.. 🤣
@@shagga070 👍
@@DLXWillington I am really impressed with your GBL charge for yours
Hearing it through my beats by drey the charge 4 modified I could definitely hear a differences it was louder and also the beat had a bigger hit than the charge 4 original. Great job!!!
Why did you say beats by drey😂😂😂😂
Wow, what a creative project. I thought it would sound louder because of the 3 drivers but the bass would decrease considerably due to the lack of PRs but hey, the bass also increased considerably along with the volume. Nice. Speaker companies should start adopting this technique on their new products. Nice job.
Awesome lol sounds like there rite in front of you with the mod version, I want one 👍
Nice vid dude💪🏻
Thanks dude
Flexing that dent on the charge 4 is LIT AF
You can add a passive radiator silicone and put it around the drivers installed so it could act as a 2 in 1 passive/active speaker like the 808 thump speaker driver design
Nice idea!
I'm not gonna to lie it looks super cool
Is there a way to add a low pass filter on the main driver.
Also im guessing with the speaker designed for a single driver porting the enclosure might actually allow the speakers to move more freely and increase the bass.
after removing the PR's does the speaker sound less muffled to your ears. Im thinkin about doin this too to my speakers, but not this much, just a small hole , because the speakers after drilling have more of an open sound to my ears through my headphones.
Hey Dr. Modify did you have the JBL Charge3/ 4 Plus 360* raffle yet ? In so any idea when, approximately how many can enter the raffle for this Amazing one of a kind speaker ? Your speaker subbed fan who loves modify something better to the way it should have been made....
Dave from Rhode Island
I love the experiment. Crossover will cut the bass to the flip drivers.. You could use just one of the two passive radiators, or use more powerful speakers from a Charge 2 or 3? I'm considering an upgrade from my original Charge, so thanks for all the reviews..
You are connecting 3 speakers in parallel. This does reduce the resistance much so the amplifier could be destroyed (charge 3 board). Please be aware of that! This time it worked but it could destroy the board.
what about phase? is that a thing to consider about this experiment?
@@dbermont of course the phase is also important because if a speaker is out of phase (wrong connection, positive and negative is confound) it will not make bass. If on driver is connected wrong, it will move in, when the other drivers move out, so the speaker can not create pressure which is needed for bass.
Yeah could have a problem, but it definitely has d class amplifier that is more efficient. At least for me I've never had issue with using even 1 ohm load on small bt speaker amp.
Im interested in what it would sound like with the end drivers wired up with reverse polarity, it may help with the extra pressure.
cool vid :)
poor jbl charge 4 😭😭😭
It's fine 😁
@@DLXWillington Can u give It to me
@@rawwdyrichh3741 no

*Visible frustration
You reduced the impedence of that speaker to 1.33 ohm.(3 4 ohm speakers in parallel equals 1.33) that increases the output power of the amp. That's why its louder.
We want more like these..
Good to know
Yes, more reasonable mods like this Wellington!
You might consider adding some stuffing (cotton or poly fill) to tame the standing wave inside the module. Also, adding additional drivers to the internal amp will reduce total impedance which could damage the amp.
For more bass (I know bass isn't all that matters, but it's fun), you'd have to extend the ends of the enclosure and add larger passive raditors. There'd be a bit of trial and error (or maybe calculation if you're smarter than me), to get the right resonance from the larger PR. More surface area tends to mean better efficiency (or dB/W), which these portable speakers really benefit from. Hope yourself or someone else does this, I'd be really interested in the results.
U should try low frequency mode on the modified one
This is super cool. I do stuff like this too lol
great experiment , unlike us you have 2 units to tinker with
Original sounds clean. The modded one sounds distorted. But it’s a cool way to salvage speakers if both were down and you could make one working speaker.
Making one with two drivers and one bass radiator would be amazing
Sounds good and louder
definitely louder 👍
It would have more bass if you hooked up the small drivers out of phase with the large one. Having them in phase creates more pressure to work against, but out of phase, the pressure should be more equal because as the top speaker retracts the outside ones expand, allowing more travel on the driver and more bass. It would be hard to get the bass as good as the passive drivers though.
Do you think or know if there are different models of charge 4 giving different performances? I know the flip 5 has different models
Try fitting low pass filters on the added speakers and a port if there isn't an existing one seeing as you have removed the passive radiators.
Can you put high excursion drivers in the sides and put a Passive Radiator in the place of the "original" woofer to be a passive radiator in the "middle"?
Might suffer punch bc of side directional speaker lack of clarity/spread.. But I like where you're going!
It sounded like the vocals got alot louder and clearer, sane with the midrange, all around alot nicer to listen to
I think it sounds better!Of coure,it does not have much bass,but for my taste (for my music taste)thats good...I love the mids from the modified one.
Your modification sounds better!
You also must take into account that the Passive Radiators are much larger than the drivers used to replace the PRs. Also another thing to remember is is that a passive radiator moves in the opposing direction of the active driver therein. While replacing the PRs with an active set of drivers means that all cone area is moving in the same direction while it's built to have a type of amplification of air movement inside the enclosure from the PRs moving in the opposite direction. Plus all speaker were in parallel which loads the internal amplifier more than it should be which causes distortion and clipping at lower volumes than normal.
Also, I see everyone talking about how before it had deeper bass, and this isn’t true, it’s the same speakers but with a passive radiator, it acts as a turbo charger for the lower frequency, extending the bass frequency on the speaker, so yes it sounds better, but in reality it’s all pushing the same bass (for people who don’t know what a passive radiator is) this is why when u turn up the volume the deep seems to go away. The passive radiators are supposed to deepen the bass at lower levels say 20-30hz per say
Thats a pretty cool idea, JBL Charge with 2.1 virtual surround channel
The modified one is not airtight anymore that's why the original's bass is better.
JM D yes
It is or otherwise you’d hear some distortion. The side drivers just produce bass at the exact same as the main drivers at the front. That’s why there’s almost no bass.
I love your channel, I think you should add jbl extreme 2 on jbl Boombox(extreme boombox)
original: bass not so pure sound
mod: clean sound no basss
Type of listeners wants:
1. Loudness ( usually available speakers )
2. Clarity ( high quality speakers )
3. Stereo effect ( can be experienced from low quality speakers )
4. Bass performer ( limited quality speakers )
Portable Jbl focused on loud and clear bass performance, if you buy 2 jbl will have stereo effect... That is the reason of jbl connect feature...
Solid video! I just did this with the worst sounding boombox i have ever heard. The Toshiba TY-CWU500.
Put in old JVC speakers firing forward and the crap speakers out to the sides. Toshiba decided to use +/- 30 gauge wires, so stripping and soldering them was an annoying chore!
Try the speakers in bass mode by holding the volume down and Bluetooth buttons at the same time till you see the light change once then you let go.
When are you going to put them out of phase and see how they sound???
This idea is so creative wtf..
I like the sound of charge4 modified more, its clear and more energetic. Fun and clear music. If there is room for bass enclosure would be nicer
Thats so cool
👍
Cool!
What i think before the soundcheck was even the result in the Soundcheck: Way more open mids, but the Bass can not completely compensate the movement from the membranes. The original passive radiators do that, but now the air pressure works against the flip-drivers and they produces air movement too. So it’s normal to get small interferences, the bass can’t work correctly. Also the overall tuning doesn’t fit any more.
For me the Charge and also the Flip are not really good speakers. A mix if both don’t make it better. JBL has to tune the Speakers better, that should be no Problem because the hardware is ok. So if JBL would simply change the sound signature i would give them a chance. So many fans say that the bass on the JBLs is great, but it’s not. Bass and hights is all you hear, but both not well defined, not strong. The Charge looses in Mids and Stage. The Flip looses in harsh metallic hissing hights and thin bass at higher levels. So it makes no sense to mix that.
Very interesting video and i really like and enjoy your comparisons, but pity about the time invested in this test project. ✌🏻
Ur my bro
You killed the bass
Yes because air space is key in an enclosure and the radiator reacts like a ported enclosure- so when you removed them you turned it into a sealed enclosure and divided the air space
The modified one sounds more dull and has less bass. I also noticed you could hear the flip speakers peaking at times and making a small crackle. It's a cool project but I would suggest maybe replacing the flip speakers with subwoofers and maybe adding a tweeter beside the big driver in the front to provide those crisp highs.
What if you only added one speaker to it and had a passive radiator on the other side, or you could replace it’s original driver with a massive passive radiator and leave the flip speakers on the side.
Hey there it's better to leave the passive radiators and add the flip speakers facing upwards
Hot tip: you can really put a nice finish onto your 3D prints by suspending them in a container with acetone present. The acetone fumes will react with your 3D prints and give them a smooth finish.
To make it louder you could have used bluetooth amplifier receicer to it or the phone. or like I did, just downloaded amplifier application. :)
What’s happening is that air pressure from the main driver is used to power the passive radiators. Now that you have the flip drivers in it, the air pressure in the cabinet is trying to woof the flip drivers but the drivers themselves are trying to woof against the main driver. So what I would do is either cut power to the flip drivers or reverse the polarities to the flip drivers.
Would have been better to add only one driver from the flip, plus the amp from the flip, and the passive radiator left alone on one side. The bass and sound would have been amazing.
The new Charge Flirp!
How about putting a passive radiator on the right side beside the original speaker to improve bass more
Or leave the PR's and put the smaller speaker/s on the left side of the single racetrack driver? Even if one was placed on the upside or other side. Sure there will be more folks trying mods similarly soon. We'll see!
Like the pulse 4?
Try porting the one you modded. Itll add more sound and will allow some more low end
dang it, i really hoped you would do low freqeuncy mode
nice video tho! :)
did you try reversing the polarity of the wire?
You really did a good job making the charge4flip but the original sounds a bit better
Good experiment. The passive radiators were far better.
It sounds good on the higher notes but not the best in bass as you said and you should try to make the extra side drivers have some material around the sides to have a radiator or have the drivers themselves move as a passive radiators.
You should make a bass reflex for better performance. It doesnt matter, because it isnt waterproof anymore
make an experiment what's gonna happen if we peel off the rubber protector of that passive radiators?
I think it is designed the way it should be..😊 You should try modifying the front drivers and make it two! 15 watts each. Or put a tweeter. 🤔
i hope you connected the wires backwards on the small speakers so when the main speaker push out they pull in!
reading thru comments plus my experience... I feel JBL should fabricate different octave versions so when plug together brings an ultimate concert experience
what about resistors to lower the power income to the flip 4 speakers? it should work right? I'm not an expert, just a hobbyist with love to the Topic xD :)
The gap was that big in terms of the bass because of the way you connected the speakers, change the wiring and the sound would be cleaner and deeper
If Jbl replaced their prs with actual drivers, they could tune the replaced prs (now drivers) with bass and the front speakers with only mids and treble. That would prevent distortion and make the sound cleaner and possibly louder. They don’t do it and there’s most likely a very good reason for that. I hope jbl can do this one day in the future as it would make their speakers way better.
Just a tip a speaker need to have a flacuating point or a space for air to escape creating a deeper note that's why when U have your boosters on the standard one it sounds deeper than the modified one
Can anyone please help me find red flip 6 both passive radiators for me to change because the silicone is chipping off and making it unestetical?
