Small bluetooth stereo speaker makes sense?

[Logon]

I could hear stereo in the two music tracks at the end of the video

I don't know which system you listened to the two tracks through, but I just reran the test for fun through a PC and a pair of headphones and I can confirm that I didn't perceive any stereo effect in that video.

Just sayin'...

I too listened via PC on headphones.

I would take a second listen, but I really can't be bothered! 😍

You're right, at the end of the day who care?


P. S.: But at least we have given correct information to those interested in that JBL boombox...

Precisely to give correct information, which however has further confused things because it is said, but not explained, I have just found a couple of reviews which state that a certain stereo effect is perceived because the signal is not downmixed to mono.

https://www.rtings.com/speaker/reviews/jbl/partybox-encore-essential ("It can play stereo content without downmixing it to mono")

https://latestintech.com/jbl-partybox-encore-essential-speaker-review/ ("it played stereo content without downplaying it to mono")

I honestly don't know what that means and probably any other single speaker receiving a stereo signal would behave like this, but this one has two tweeters!

Now I guess: could there be a technology where only the two tweeters reproduce the stereo signal and the single woofer does not?

When you think about it, comb filtering between spaced drivers is more likely to occur with a mono drive signal because they are producing the same sound but spaced apart. If a stereo signal is used where each driver produce a different signal there is less likely to be interference issues. Additionally with a high directivity driver they may not interfere too badly, but they can be angled to bounce off different surfaces in the room and give a more immersive sound.

You had me at "comb" so just take me you beast.

I've built a portable speaker ( measured 35 cm long ) speaker drivers were on each side , definitely there was " stereo effect ". having them in front at such small distance won't be the same " stereo effect " as having them on each side .

No matter how small the bluetooth speaker is, it still makes sense to keep left and right signal separate. Lot of music information gets lost by making it mono.

@adason could you share the source of the image? I'd like to read more about this topic. Thanks in advance!

Were it stereo with a single woofer, as I'm not arguing about the operation standings, the woofer would need to be a DVC device if only tweeters complemented it. DVC woofers have long been used to combine 2 separate channels into a single output device.
