JBL Charge 4 | How to activate Low Frequency Mode | Bass Test (Disable DSP)

The JBL Charge 5 portable bluetooth speaker was just announced in 2021 but it's predecessor still has plenty of power. In fact, the main driver is fed with the same 30 watts as the new JBL Charge 5, which also has a separate 10 watt channel powering it's newly added high frequency driver.

Video showing how to disable the DSP aka activate "Low frequency mode" plus a short bass test illustrating the effect. The new JBL Charge 4 is part of JBL's 2018 lineup which consists of JBL Go 2, JBL Clip 3, JBL Xtreme 2 and JBL PartyBox.

Video showing how to disable the DSP aka activate "Low frequency mode" plus a short bass test illustrating the effect. This can be done for fun to watch the driver and passive radiators showing extreme excursion or to achieve low bass response at lower volumes when used with an equalizer or bass boosted songs. With normal songs you don't get any benefit! *Beware this is not a safe mode for the speaker, it can excessively heat up, bottom out and get damaged. Use with caution!!*

this is the best v video regarding the jpl chrge 4 ever thank you alot i tried it and it worked perfect

[mph]

very nice man
ps probably the only reasonable video where the bass boost function is shown

[jackmiller]

Honestly, it sounds worse when I enable it. I notice the passive radiators definitely shake more without it enabled, I am using an equaliser with some bass boost and keeping it off gives better low end and mids. This is listening to fabriclive 37, a classic dubstep album with a lot of subbass emphasis. Not sure if I'm doing it wrong or what, but someone else said that turning the speaker on and off resets this function, is that true? Cheers in advance for the video and your response.

Also please do a bass test without the cover/grill

This is the easiest tutorial i've ever seen

This function is good, greetings from Mexico

[LedZeppelinWolf]

Suggestion for people who have an iPhone, bass sounds better if you don’t use this function and in music settings on your phone change EQ setting.

This function is only meant to be used in very particular cases.

If you do Bluetooth and Volume Up (+) it resets the speaker...meaning it turns of and when you turn it on it will disconnect from your phone...meaning you will have to pair it again

[benjaminmonroy]

Can this mode hurt in any way the speaker ?

[nicig]

It doesn’t work, I can hold „-„ and bt button for as long as I want, nothing changes regarding sound or lighting

[james-]

May someone explain the benefits of low frequency mode please

[fatih]

thank you for sharing. have you ever tried how much latency goin on with jack connection when dsp disabled? Im looking for low or no latency speakers in this size?

[SubsWithNoVideo-sqkp]

Does Low Frequency mode damage the speaker?

[lleennyyy]

If I hold Bluetooth Button and "+" then seconds, 1 LED ist red an the other ones are white. Then the box go off and I have to turn it on again. What is this? (Xtreme 2)

My Charge 4 is stuck in low frequency mode, every time I do this is goes back to normal but when I turn it off and turn it on it goes into low frequency mode. I’ve tried factory resetting it but it still doesn’t work. Can you help plz!?

[harvydabu]

How to do it? Keep on press and hold the bluetooth and down volume but no led flashes

[DonTuli]

Once l did the button combination again should the first bottom led light gone red for like 2 seconds? Im a lil scared
