I can understand why he'd think they were fake but passive radiators do actually serve a genuine purpose en.wikipedia.org/wiki/Passive_radiator_(speaker)
@@loudspeakertestsmorebyaida3804 Well if it sounds like crap, then the science behind how passive radiators 'work' doesn't really matter does it? If you think they sound good for their size and price, well, fair enough.
@@gearfacts For the price, I think Logitech is decent enough. I had the Z313 and it was decent. Not the loudest, but has plenty of bass. The second speaker is not fake at all. A lot of people call passive radiators fake speakers, but they really are meant to improve the bass and Logitech said there are 2x passive and 2x active. Just because the speakers say they’re 3 watts doesn’t indicate a fake speaker either. Logitech says they’re 10 watts (peak). Peak is different than RMS. And Logitech says they’re 3 watts x 2 (6) watts total (RMS). And the passive radiators do move.
@@gearfacts And watts really don’t matter. Some shitty speakers claim they’re 6,000 watts and that’s impossible. More like that Pyle brand shit. Pyle is a scam. It’s no more than like 50 watts for their PA shit and definitely has inefficient sensitivity rating. If you want loud speakers, then I suggest you do look at the sensitivity rating. Anything above 90DB at 1W (2.83V) at 1 meter is considered excellent. If you want bass, I suggest a speaker with a passive radiator instead of a sealed enclosure most of the time if you like louder bass. Anything below 80HZ is consider excellent. If it’s over 150HZ, then it’s terrible.
Zachtheios -bit heroes- Fair point - I think if You look at it from a marketing perspective though it is fake in the sense that the appearance of the speaker is clearly intended to make the consumer think they are getting 4 speakers. That’s why I used the word ‘fake’. But yes, the concept of passive sound radiation is a real thing #gearfacts
Gearfacts Ihome advertise like that. I had an iP46 and says 4 speakers and they said two passive and two active. Logitech uses passive radiators on many of their systems such as the Z4.
@@loudspeakertestsmorebyaida3804 Can a passive radiator be defined as a "speaker" though? It doesn't actually emit sound, it just passes it through (a tiny bit of it, in this case!)
A "passive radiator" can emphasize bass frequencies in a well-designed enclosure, but Logitech appears to have been a willing slave to fashion with this design. Of course - the 'proof' is in the sound - not the components; if they already sounded superb, you probably wouldn't have thought to dismember them and cannibalize their guts... (IMO - this is a good hobby for you; please don't adopt any pets...)
They have these now but repurposing the amp from these speakers to use a larger speaker is a decent idea because the most playback of audio is usually done at about 1 watt level (most speakers have a decent sensitivity level so as long as he plays within the amp's threshold he should be okay). At the time of this video I know those particular speakers were going around $20 (bought a few for relatives since I considered this to be one of the best overall budget performers) so him "Frankensteining" those other speakers to it since it appears he had them lying around only cost him in time. For the cost, size, and design I thought Logitech did a great job for it's time but I can understand where it may be lacking in a larger room.
Agreed. I think there’s some merit in the whole “bass reflex” thing but in this case I really think it was just a marketing ploy. Logitech’s Bluetooth speakers are great, but I’ve found their computer speakers to be consistently mediocre.
Got these speakers in 2019. And yes, I see they use a passive radiator method. But bass reflex comes through better that way IMO. With proper equalization, I'd say it's worth the $22 spent.
Those cheeky buggers at Logitech. I mean I understand that these are cheap speakers... but why not just have a single cone and save space? The speakers could be even cheaper due to less material and space used.
I have to say it, but every time I see the thumbnail of this video looking through your channel, I always think it looks like the speakers on the edges of the thumbnail are saying "HUH? WHAT? I'M GETTING NEW SPEAKERS?"
For God's sake, Lad. Don't open anything by force - you could break PCB that way. There was a nut on the potentiometer - on the front panel right under the plastic cap. Another thing is that those kinds of "fake speakers" are present in much more expensive mobile speakers - JBL "charge" series for example - so it is hard to complain about them in 35$ speakers.
wow i was corious how that tricky brand give 2 full range speakers in those price point, now i got answer. Idiots who talking about passive radiators, people no one make a passive radiator who look like normal driver. Look at creative peeble. After Logitech Z333 they still do that shit.
It is indeed a passive radiator - and it doesn't do anything in a system this size, as your ears should be telling you. That's it for today's Spot-the-gimmick course.
You really should remove the word 'scam' from your title, as your accusation is unjustified. Logitech mentions clearly on their website: "Each speaker has one active/powered driver that delivers full range audio and one passive radiator that provides bass extension." So no lie from their part at all, regardless of whether you think the passive radiator 'theory' is fact or fiction. You didn't need to take apart the speakers to find out the truth. If you play those speakers, you can actually feel the passive cone vibrating, so it's not 'just a hole', as suggested in one of the comments.
Point taken, but as someone who worked in a tech store for a very long time, I have seen countless people make their decision on the spot without referring to technical specifications. I saw a lot of people impressed by the "wow, four speakers" appearance of this speaker set. My point was that the appearance of the product is part of the marketing, and this product benefits from people thinking they are getting something that they aren't. I take the point that Logitech has disclosed the truth and that buyers should inform themselves, but the fact is - they don't. And it's unethical to benefit from that.
@@gearfacts the fun: Destroy the logitech speakers Second: Either You could just removed the front casing of LG Speaker, Drill A Hole from Sides so that The Knobs Can easily be reached, Or just make an entire new speaker casing for them.
@@gearfacts passive radiators can be good with bigger speakers or a subwoofer enclosure and stuff like that, but having a passive radiator on these speakers is pointless, they play no bass lmao. Just trying to get people to buy it I guess lol
Not exactly. Bottom membranes are working but as passive ones so they are "pimp up" lower frequency a bit more - but you cant expect too much from a low-cost 5W RMS stereo set.
