Been designing speakers for many years and speakers have changed a lot. Some are best in ported and some sealed according to the speakers parameters.

[@doemaeries]

How would you determine if a chassis ist best for sealed or ported? I've read that if fs/Qts is around 50, it's best for sealed while a value around 100 is best for ported. What do you think about that?

[@77Brainfreeze]

@@doemaeries This is called EBP and it's a good starting point but you can still make a high EBP driver work, the box size might just not be optimal. If you already have the driver you can make it work you just need to model it and see what you're in for. If you don't have the driver yet it would be best to buy the driver to fit the style of box you want to build.

My SEALED house speakers generate far more Vibrational bass, than my Ported speakers. The Port does not change make the speakers any more powerful. The Magnet strength, Coil strength, are what create the strongest potentials. The Subs shown here, are not for Car Audio. They are for home theatre, and possibly also to add depth to music. Unless you live in the middle of the country... you cant blast High Air Pressure Subs, in a typical apartment. Furthermore, Its Immoral, to blast Car Subs in the City. People live in the apartments above the storefronts... and it Ruins these peoples Sanity, and Lives.

Ported Is mainly made for and sold by musicians. A frequently purchased subwoofer is, for example, the Yamaha HS8S and JBL LSR310S. Then a ported turns out to be better 🤔

[@Grimmsha72]

I've always preferred sealed. I also like just ten inch subs for the much tighter quick hard hitting bass they reproduce. Though in my huge roomy 85 GMC Suburban, just wide open no trunk, bass lacked in that wide open environment. The same amp/sealed box/speakers in my Ford Tarus was much more pronounced sitting in the trunk then in the Suburban. The type, how they are arranged, the box and the amp can really make a huge difference depending on the setting they are placed into trying to get the sound you are looking for.

[@angrodNumenesse]

Oddly enough, Ford used the trunk space in the Taurus to be a 'box' to help with bass. There were two 6x8 speakers in the rear shelf standard but there was also a spot for a 6x9 speaker that was meant to be used with the JBL systems that were optional on those cars. I didn't have the JBL system in my Taurus, just the MACH audio, but with some work I managed to add a line driver before the main MACH amp. The line driver had a subwoofer line out which I ran to a small (300 watt) sub amp and a 6x9 speaker I added in the rear shelf. I didn't have it loud but it added quite a bit of low end bump. Depending on what I was listening too the inside of the car would shake at a moderate volume. I miss that car and the system (I kept the components.) The factory Sony system in my Fiesta just can't compare.

[@Clint3571]

A good sub of any size can produce punchy bass. I have three 21 inch subs in my theater that can reproduce anything from 15Hz to 200Hz with no problem. When you go to a concert and hear the quick drum bass it is from ported 15 or 18 inch subs, just for reference.

[@davidzoller9617]

Summs it up. Building a sealed speaker has the advantage that you can quite precisely create your desired "Sound-Design" by the inside Volume (Qtc) of your housing. For a good vented speaker your driver probably will be more expensive then the driver matching a sealed Box design. If you want low bass range for a small driver you have to go for the ported speaker. If you want low bass range in a sealed subwoofer the housing easy gets huge. For people who don't really car much about sound a cheap 2.1 system with a vented sub will just do fine. I got one of these, was under 30$ and for that money it can't get much better. On the other hand, you can buy high prized speakers that are crap. It's mostly just about marketing. A good speaker system is one, that you can enjoy listenimg too all day long, without getting nuts.

I built by own box and designed my own port for a sub to go in my 96 civic in high school. I paired it with a cheap pioneer amp and woofer. tried to set it all up to roll off pretty heavily around 40 hz. I thought that would protect the speaker. I was the designated driver to a party one night. my friends were all pretty excited to hear the system I put together. non of us cared to much about sound quality at the time. we cranked the volume and destroyed the sub. I learned the hard way that if you are using a ported box you need to quality sub that won't rip itself apart easily. I never did replace that speaker.

[@radon222u]

Below the tuning frequency, ported sub driver has enormous excursion as you go down. Sealed on the other hand has limited low excursion even below tuning frequencies. One more advantage of sealed is that the woofer membrane remains rigid compared to vented because the pressure difference in case of sealed across the woofer stays high at extremities as compared to the woofer in vented.

[@Dreamer5211]

Good explanation , sealed subs have always had musicality on their side . They are able to recreate the lower registers of the musical spectrum. A ported sub is good for bang bang -- boom boom , personally I would much rather have lower musical notes that just a bang and a boom !!

[@Monkeyseemonkey79]

And the boom from a sealed sub is usually still exciting and impactful (vs not having a subwoofer)

[@PlatinumEagleStudios]

I use a Veliodyne IMPACT-10 ported subwoofer and it's awesome. i prefer ported over sealed because not only does it provide louder bass output, it also provides cooling for the plate amp and the driver itself. In a sealed box, the heat generated from the amp has nowhere to go, and that could be a bad thing. I don't know how they manage to keep sealed subs from breaking due to overheating.

[@rightturnnews805]

Put a bottle of ice water near the port to chill it out. It will thank you...

[@tomkocur]

1. Class D 2. Plate itself is a cooler, some amps have heatsinks on the outside 3. There's a significant amount of air inside the box, in a lot of cases its capacity is more than enough to cool down what's needed

[@jaefrmbk2k]

they manage tho

[@stefanweilhartner4415]

I invented a sub based on the transmission line design and registered it with the AIPO. Australian Intellectual Property office. I'd worked in HiFi shops and wanted to make a better sub than was available commercially at the time. I succeeded. I tested Ported designs and settled on a sealed design. Chalk and Cheese. Sealed subs are tight and fast as this video attests. Kudos Kanto!

kickdrum--->sealed, for everything else ported, it all comes down to the kind of music you hear

[@georgewalker9978]

Works different in car audio. All kinds of figures to put in the equation. Cabin size , power supply, wire size, driver parameters, location . I have a 4 door pick up and the only place to fit an enclosure was under the seat. Your backwards on the frequency you get with a sealed box. For lower resonate frequencies a sealed box has to have more air space. A ported box can reach lower frequencies in a smaller enclosure . Trick is to make the port proportional to the available air space and get the dimensions as close as you can to the recommendations of the specific driver's manufacturer. On mine it was real tricky. I had to make a fiberglass base for the subs I needed for the results I wanted. Port was made to spec with dual taper to increase sound compression , multiple chambers for a variety of frequencies. Of course the box was made specifically for the drivers I used.

[@stefanweilhartner4415]

very good explanation. i like a sealed dual subwoofer architecture where the chassis are opposing each other.

[@csimet]

Good overview. I'm trying out a semi-hybrid design, the RSL SpeedWoofer 10S MKII. It has a non-traditional elongated front firing port (rather long & thin, not round) with extra internal baffling, that is supposed to permit better pressure and response like a sealed enclosure. Everyone I hear is raving about it for a sub

[@namgodz]

...and this is why I love the classic Large Advents speakers. Back in the day your 2.0 system was really a 2.2.

[@kondirecs]

Spot on description. Sealed subwoofers are preferable for music; they sound more controlled/more responsive and precise compared to ported, that might be better for surround sound. Many small ported wall speakers should have their ports blinded with foam or other materials to make them more tight and better sounding. Especially if placed right agains the wall. Deep bass is not everything 😉

[@kaedeschulz5422]

It's aways a matter how they are tuned and designed. With port noise it's off course a matter of size and how each side is rounded off. I build my own speakers and Experiment a lot. If the port tuning is very low (in my case my sub is tuned to 15hz) The group delay caused by being ported is much lower to the point that one can only seperate the sound of it from a sealed sub because it goes lower. IF using the same driver! That being said. Driver choice is a HUGE factor in this! I just built some Bookshelf speakers with a Punktkilde AUGWL0016-JN03 woofer in a about 17liter ported box tuned to 40hz. I expected the group delay caused by the higher port tuning to ruin bass clarity but it didn't. It's actualy the best sounding bass i have heard so far. The next most authentic sounding thing was a PA subwoofer on a concert. So it's always a matter of the sound engineers choices when building a speaker.

There's a saying with subs... they can be good, small, or cheap - pick two. Since you want good bass in a small space you'll have to spend more on a powerful amplifier and a sub that can handle high wattage.

@@uwebaganz5144 1) Your particular build, is NOT how standard ported speakers work. They use specifically designed (Tuned) tubes, at specific lengths, with the specific diameter and end-flare. The reason for the port like this, is to make an automatic bass frequency sound, any time that air moves out of it. (Hence, the bottle blowing example) Your use of much larger squared ports (NOT TUNED !!!) and use of TWO ports... is COMPLETELY different from standard Ported speakers / Subs. In fact, that design, is closer to an "OPEN BAFFLE" design, rather than calling it a "Ported" design. Hence, why you do not experience typical Port "Chuffs" , and typical port Distortions. But your design misses the entire Point of the Port... which is the Artificial Lowered Bass sounds... that are only created by that specially designed Port hole. Hence, again... making your sub, more like an Open Baffle sub. Which makes your entire Argument, Completely Nullified. And yes, the drive does matter. But put the best drivers into a REAL ported design... and you will still get CHUFFS and Distortions. As for whether Sealed or Open Baffle is better... is a whole other story. Sealed speakers produce plenty of strong vibrational bass. But you will need a very powerful driver to overcome the compressed air. Such a driver will be less efficient requiring much more power, to driver it. Open-Baffles have less natural distortions, as the air is only being limited by the sides of the box. A more efficient driver could be used, as a result. That said, Im not sure that the overall vibrational bass impact, will be as "Tight". And there will probably be a lot more potentials for room distortions, as the bass will be traveling in two different directions at the same time. You will also increase the likelihood of dust and grime getting lodged into the drivers... causing future distortions. Every design has its particular positives and negatives.

According to me sealed are good for home theatres and ported for music... What's your view..

[@melovemusic69]

You have it reversed according to experts. Sealed reacts better (quick)and more accurate for music..

[@manishthakur5996]

@@melovemusic69 actually ported go too long with low frequencies... Watching movies with heavy subs distort other vocals.. Especially watching war scenes.. When it is music... Low frequencies add magic..

[@new-kids-on-the-block]

No port is better fore movie seald is more true 2 its sors

[@rhiwderinraytube]

I have a Bowers and Wilkins sealed type and it is superior my ported Pioneer one which itself is very good.

Go for a passive radiator... no chuffing and they are far tighter

[@davidhunter9434]

Someone might have already asked this, but why doesn't the YU2 have a low-frequency roll-off switch, say at 80Hz? This would make them so much more usable with a subwoofer, like the Sub6 or Sub8. The YU2's image like crazy, especially with vocals, but when the volume goes up past 85db, the little mid/woofer driver just can't hang, and distortion, buzzing, and general sound stage incoherence becomes a problem. PLEASE update this wonderful little speaker with that roll-off switch. It would make the YU2 a sonic wonder with a sub, rather than a love them/hate them experience.

[@jamesb9300]

But, the depth of bass from a sealed sub is deeper, I love it

[@dizzywow]

No, it's not.

[@YogiTheBearMan]

I think you missed the whole video

[@furkyyfurkyy]

Really easy to understand every details, thanks so much...

[@OpenRoader]

What about Subs with passive radiators?

[@jshoover2199]

Incredible video. Thanks for the laugh AND the information!!!

[@mullholand]

Such a well done video - so I hate to disagree with you. I think if you pay for a really good ported sub like a SVS PB anything (I have two - PB 4000) and for home theater - that deep bass is unmistakable! BUT... I have 5 15" sealed subs for outdoor use and I have to say - those sound EPIC! Powered by Crown amps.

[@panzerfan]

You are not disagreeing with him. If you aren't restricted volume wise, there's no replacement for displacement. You need that displacement for ported subs. Personally though, I think having dual sealed is better than a large single ported sub ( ie 2x SB-3000 vs 1x PB-4000)

[@TheSzyko]

Would you recommend getting an external sub over a 3 or 4 way speaker like the Fluid Audio Image 2 or EVE Audio SC4070? I want to extend the low end in my studio.

[@zodiacfml]

correct. more than a decade ago, I DIY an enclosure for 12" sub for my car and chosen ported box. While I did get my childhood dream of having too powerful bass in a car, the sound quality is messy, sloppy, and at high SPLs the port noise is just annoying, killing the enjoyment. If I had chosen sealed box, the build would have simpler and faster and probably kept that system.

[@juanosorno8153]

Great explanation. I learned a lot with this video. Thank you

[@philipsawyers719]

Thanks 👍 I appreciate the difference now.

[@forog1]

I'd go passive radiator before sealed for in home use. It's the best of both worlds and in my opinion its best for games movies and low listening volumes. In vehicles Port all the way. I had a sealed sub and though it was accurate it didn't hit the way I'd like it to unless I had 2 and I'm more of a 1 sub guy so I want the best output from the one sub and save space. But bottom line if I couldn't do a ported sub id go passive radiator route next and skip sealed because it's basically the same thing in the end anyway just in all way to my better than the sealed in every way. Port has its own advantages over the radiator. I feel the radiator is the sealed box's 2nd form lol but of course the radiator its probable the most expensive route so there is that to take into account.

[@vinaybellave6498]

You guys rock!! Awesome subwoofer science!

[@phreak1118]

They both have their place. Generally sealed sounds better with music and ported sounds better with movies.

[@panzerfan]

@@pickleadaykeepsthedoctoraway It's a matter of good enclosure design and giving the said speaker adequate space to perform. Subs require even more care to place properly than the average ported bookshelf.

[@VirtualGuth]

I prefer sealed loudspeakers in general, but aside from subwoofers they are very hard to come by these days.

[@lort6022]

Because they suck.

[@smetljesm2276]

Very nicely explained. Much appreciated 👍🏻

[@calvint3419]

Very good demo. Make me want to try out. Maybe seal sub qith passive tranducer can be best of both worlds.

[@rcary]

What about subs with a passive radiator?? Is that essentially a port with a flex covering?

[@Okanoggin]

Wicked video, thanks for explaining this in layman's terms

[@andyamysarizonaadventures5450]

If you put an enclosure in a cars truck,only do ported! It really hits louder and deeper.

[@AudioBoi1]

great explanation, thank you

[@benboyer2776]

I’d put a ported JTR Captivator 4000ULF against any sealed sub on the market. Hands down the best sub I’ve heard in person, whether it’s ported or sealed… you need a high quality driver to have a good ported sub

[@kevenharvey9711]

Ported costs more to build, store and ship, and is bigger, so a fair comparison is hard to make. You could give the sealed sub a better amp or driver and it might end up giving better overall performance.

[@dr.tissonjob5707]

I have a polk audio psw 10. At what range should the low pass filter should be kept to get a good balanced performance?

[@KantoSolutions]

crossover point is dependent on your speakers. You want to set your crossover point at the frequency of which your speakers start to drop off in bass response. For full size bookshelf speakers, 80 Hz is a good starting point.

[@dr.tissonjob5707]

@@KantoSolutions I want to know regarding the value of low pass filter at the back of the psw 10 subwoofer!

More power and vinyl finish on newer versions

Nice video,i have a question,can you close a port?Sorry for mine bad english,i am dutch.

Sealed for the drum kick and the ported for the rumble. Buy both for the bass wars.

whats best way to seal,,, ported sub... what to put under its feet so house dont crash down from structural vibe

[@TheManunderwater]

Brilliant informative and clear video. Thanks

LARGE SEALED BOX FOR ME...take the size they recommend for ported and build it sealed.
