it just depends of your needs - ports : loudness, compactness, cheapness, easy tuning with calculation tools - passive radiators : waterproof, clean bass, good looking, no bass port noise, no damages below the tuning frequency, no open baffle effect at maximum volume
i'd say it's easier to make a compact speaker with a PR though. with a port you have to calculate the extra space used by the port or your calculations will be wrong especially with something like WinISD
I agree with BH4, your box volume is the same as a single speaker sealed box with a PR vs with a port you add 25%~ more volume. So I would say PR's are more compact, that said you still need a box that's large enough for both the speaker and the PR.
Ports are better for big subwoofers but for small Bluetooth speaker you can't use ports as it will make the sound worse unless you make the encloser much bigger which is not suitable for portable speaker. Plus the speaker doesn't remain waterproof.
i was actually really dissapointed w/ the bass output of the speakers. if you have a sub they sound great, but kinda wish i would've gone for the Cerwin-Vega's that still use full size woofers. I can still remember back in the 80's and 90's before subs were popular they use to sell speakers to where you didn't even need a sub. good luck finding a pair now, unless like i said, you go w/ Cerwin-Vega's.
Exactly, there is no point of making compact/waterproof made bluetooth speaker to have big ass port to achieve the same level of bass that can be achieved with passive radiators. It's pretty hard to fit proper port inside of speaker that's size of water bottle
I want to build a Bluetooth speaker myself, the problem is, when I want to use a port, I would come to a housing that has like 16 liters of volume, already for a subwoofer with 3 inch diameter. The housing shall be small and nice and modern looking, when I want to use a radiator, is it possible to have like a tube in the housing, where on one end the speaker is mounted and on the other end the radiator?
I've been boulding speakers and subwoofers for 20years + and my experience with passive radiators are that they sound tighter and more accurate. Because of the radiator and the driver is moving out simultaneous and in simultaneous the pressure in the box is much greater than a sealed system, both drivers react and stop even faster. That gives a great punch in the low notes.
Why are you naming it as an advantage that driver and radiator are moving out simultaneously? Same is true for a port. If not, there wouldn't be any constructive interference. Also the radiator has to get excited by the driver, just like the air volume in the port which acts as a resonator.
With the mass added to the radiator, the radiator can get a very long travel. And the pressure in the box becomes very high, witch prevents the active speaker to move and hit the bottom of the magnet. My experience with passive radiators is that the bass becomes much tighter, clean and the drivers can handle more power.
Very interesting subject right here. I definitely agree with you. I think most bluetooth speakers have passive radiators so that they can be waterproof.
The Earth Is Bread Yea and with passive Radiators you can geht small bluetooth speakers to Play low and you dont lose Box Volume like you would with a Port
passive radiatoren haben noch den Vorteil wasserdicht zu sein. grad bei BT Speakern wichtig. Bassreflex Rohre können zu dem Windgeräusche verursachen, wenn die Windgeschwindigkeit zu hoch wird und der Port schlecht geformt ist (mit zu vielen Ecken und Kanten).
1) What about a third choice, besides passive radiators and ports : just a round hole. 2) On which wall ? Not counting the cabinet wall where the speakers are mounted : Which of the five remaining cabinet walls would provide the best effect ? 3) What size should the hole be in relation to the woofer, to the enclosure volume ? 4) Should passive radiators be the same size as the woofer in the box ? 5) Sealed OR Vented ?

Julio Jesus Jimenez 1) in which way would a round hole in a cabinet support a speakers bass response? 2) the effect is mostly the same because frequencies below 200hz don’t really have a direction If you get very close to a speaker the side walls are probably best because everything mixed slightly nicer at those distances 3) there are specific formulas which calculate the exact dimensions of a port using the woofer parameters 4) it should roughly move 2x more air than the active woofer, so it should either have twice the area or twice the excursion of the woofer itself 5) it depends on the woofer that you want to use, both enclosures can sound great if designed nicely
so you've forged your opinion by comparing completely different systems and generalized that ports are worse than radiators? sorry dude, that's not a very smart thing to do.
If u dont want speacker sistem you can,t hold in one hand just use bass reflex ,its better ,and free,only calculation,a pipe or a bass reflex will do same thing ,but passive radiators must be tested until they are good for sistem ,i,ve seen a lot of chineze good speackers copy of jbl that has passive radiators harder then the power of actual speackers,the ones that are good use soft radiators ,vs high end jbl uses a enforced membrane that not even jbl speackers can't move them ,so just change the pasive membrane you will se is good for the price
Ha. Very interesting explanation..I love it...but also confusing...why is it then that with a passive radiator it has to be completely sealed with no air escaping at all to sound more effective, while with the ported speakers much air is coming out and they still sound good...if the role of the PR is to keep the air as sealed as possible in the speaker enclosure why not just discard it entirely and build the speaker without one...
of course the enclosure has to be sealed with a pr because otherwise how is it going to move effectively? it’s about moving air at a certain tuning frequency, which you can either achieve with a port or a pr tuned to the correct frequency. i’m having a hard time explaining this rn so maybe there’s a good and detailed article out there that does a better job.
Passive radiators are better than ports when the box is tuned for it, and its really hard to tune. JBL honestly doesn't make a good example for passive radiators, Vanatoo is a great example, despite not really having much name recognition to the masses. Idk, I'm a big planar guy, If I could my sub would be a planar. I just like the really tight bass you get from it, and though you don't get the same level from say a passive radiator, you still get more than a ported speaker.
you dont have 2 bass drivers ,you have longer bass,one bass from driver ,one from retreat of bass driver,like bass reflex ,if u want a hifi just go for sealed ones ,but they go big in volume,and high in speackers,that's why studio only uses sealed ones..
he passive element always goes deeper than the bass port A pressure element or a passive element is already an old invention it is no longer used The bass port lasts longer The pressure element or passive element decomposes faster The speaker cannot get air It's overheating And finally breaks down There must be some reason why those passive elements are no longer made, are they too expensive or do they decomposes faster the bass port is much better it lasts longer i like more that passive element is an old technique it is no longer used that's it
You can't buy passive radiator's with magnets because the magnets arnt needed? Sony, jbl etc all use just weighted diaphragms, surely they know what there doing
did I say with a magnet in the video? I mean passive radiators with everything but a magnet the moving mass has to be moved in a linear way a metal weight in a rubber surround doesn’t do the best job
Honestly I think the reason I like passive radiator speakers is because of ADHD. Something about the speaker components moving with the bass of the song that I’m listening to is so mesmerizing
