I've recently started using my brand new Boombox 2, and it's honestly great, but today I've noticed something really frustrating. So certain songs - can't specify what kind of sound, there are just like 2 songs in my 90 song playlist that noticeably make the speaker crackle. It's not an obnoxious crackle that makes the song unenjoyable, it's just a slight crackling noise that I know should not be there. I've also noticed that when using my older Ipad to play the music instead of my phone, this crackling is much more present and can be heard in more songs (wtf?). So is this just a connection issue? Or should I return the speaker asap because it's a faulty device? I have no idea, but this really frustrates me. The speaker was too expensive for such inconveniences. I just find it very weird, like in most songs the speaker does amazingly fine, even better than my harman/kardon or sonos speakers, but in some cases I can hear that slight annoying crackle... If someone maybe knows something about audio stuff, the song that noticeably crackles is: Tiësto - Show Me, first 25 seconds... Thanks Edit: Okay, so today I did more listening and dug a bit deeper with this issue. The speaker is working flawlessly, in almost every song. The crackle/buzz is coming in from songs that are heavy on 16khz sound. I found this out by using the equalizer in Spotify, if I turn down the 16khz completly (during the tiesto song), it stops with the sizzling. I'll add this in an edit too. Anyone has an idea if this means a bad connection in the speaker, a bad tweeter or just that the speaker is not good enough to output that type of sound? Ty Edited December 30, 2020 by ProPigeon

Try this track—it has a strong bass foundation right from the start.

This one sounds just fine. I mostly have bass heavy songs in my playlist ( https://music.youtube.com/playlist?list=...VQW2gHXd7C ), so that's not the problem. I thought it might be a tweeter thing? I'm just hoping someone knows better...

I do, but it feels odd, maybe? Just not bass.

Reducing the volume doesn't necessarily stop the crackling. It could be due to excessive sensitivity of the AMP+speakers, or possibly a very high volume level. An RMA might be necessary if the issue persists.

I tested it now and it begins to crackle around 30% volume (the first 25 seconds of the tiesto track). It isn't actually cracking, just a kind of distortion.

I listened to this track, and it sounds almost identical to the original. For better quality at louder levels, you'll want a high-quality audio system.

Check if the Bluetooth connection is active at full power. If the phone is set to maximum volume, it could be interfering with the speaker. Adjust the phone’s volume to a lower level and test again to determine the source of the issue.

When you press the volume controls on the speaker, the phone also adjusts its volume to match consistently.

I spent more time listening and explored the topic further. The speaker sounds great across almost all tracks. The crackle or buzz appears mainly in songs with high 16khz frequencies. I discovered this by adjusting the equalizer on Spotify—lowering the 16khz setting during the track’s intro stops the distortion. I plan to note this in my edit. Do you have any suggestions about whether this points to a speaker issue, a tweeter problem, or just the speaker’s limitations?
