Agree, I have the partybox 300, pretty decent warm sound. I also have the charge 4, that I use to bring easily on camping without a car etc. The extreme's are better than charge's. But yeah I would recommend the partybox series myself. 100's are a bit small, but possible to put in a backpack. 300 has decent sound for 10 people with dancing

r/JBLLoud, bassy speaker recommendations?

I would go with a partybox, generally the larger the better, just whatever is in the budget. Do some research before you buy tho, some of them have their unique twists, such as my 300 isn't compatible with the app, something I could've avoided if I'd done a bit of snooping around.

I love my JBL Party box 100. I tried the 300, but the 100 sounded better to me. I feel like its the best cordless speaker that I've heard. It is large though.

r/Bluetooth_SpeakersI need a Bluetooth speaker that can fill a 1,000 SQ shop relatively loudly.

JBL Partybox serie 100 or 300 should do the trick. Otherwise, a cheaply option would be a soundbar with a subwoofer. Since it will never move and don’t need the waterproof, it will cost about 200$ for 200W+ of sound.

Partyboxes are fine tbh, I don't see why audiophiles hate them

Yeah.  I've heard a few different PartyBox models.  For me it's that the $3000 partyboxes are hot garbage. but the $300-900 ones are REALlY good.

JBL charge series is always a great buy, With a $150 budget. I have had my JBL charge 3 since 2018, only recently upgraded to the party box series, because I wanted something bigger and with way more bass. For a desk speaker the charge 4-5 is perfect, it has enough bass with EQ added. The flip and the other smaller ones that you can clip on, are going to be slightly quiet compared to the charge series. The charge series is the happy medium between good sound and portability.

Depends on the speaker. Some of the delay is caused by Bluetooth, and some by the DSP (signal processing) - aux will bypass the Bluetooth, but not necessarily the DSP. Some speakers have minimal-to-zero lag on the aux (Minirig, Tribit Stormbox Blast) and some still have significant. For example I believe some of the JBL PartyBoxes have lag on the aux in but not on the daisychain as that bypasses the DSP :)

What Adam says, the smaller JBL series have a passive membrane which serves as the Subwoofer, but its in no way as controllable Like a normal Driver. the ones inwould recommend are from the partybox series, they have sizeable drivers and two tweeters for the high frequencies
