The Great Subwoofer Debate: Ported vs Sealed - Which Sounds Better? KICKER Comp Gold

[@ClementeGalloJr]

For musical accuracy, sealed. For being as loud as possible, ported

[@wal]

Agreed, the energy created by the ported enclosure with some of the song tracks was 👌

[@hakanberglund2084]

Not true at all

[@iamgriff]

I always thought rock music sounded better with sealed box, and rap music sounded better in a ported box. Tighter bass from sealed, more boom from ported has been my understanding.

[@hadbl12]

Question, I understand higher numbers at 50Hz than at 30hz, but how did it do it with less power. Can you explain that for me?

[@srp365]

Highly depends on the woofer's T/S. There are subs that produce better transient response in ported than other subs in sealed. One size fits all subs (sealed or ported) generally don't excel in either type. Comparing it to itself, yes, your observations are correct, but choosing sealed.or ported based solely on "sealed is tighter, ported is louder" is simply ignorance on display. Building the best enclosure based on your goals according to your woofer's T/S parameters will yield you much better results.

[@joshuaferris8728]

I’ve always preferred sealed boxes because I agree that the bass is cleaner and tighter. And just love kicker gold subs. I wish they’d re do the k label on the cap.

[@meaghancote-mcauley79]

Sealed 10s are good for drag bass and quick bass possibly 2 -10s and 1- 12 to have a well-rounded system. Each speaker has its amp.

[@jamegumb7298]

I used to think that. And while a good general rule, some woofers just will not work well in a sealed system. That said, if you build a good box and brace it well (best I did was build one out of a very rigid sewer pipe, for real) it is almost as good as sealed. Now I am testing the Ripol and a 4×12 open baffle. Ripol works best probably but cut it at 100Hz absolutely no higher. In the process of drilling some cement tiles to hopefully use it for a new Ripol. I think that will be the golden standard.

[@Rentta]

Sealed boxes also were nice thing before we had subsonic filter (safer for the woofer)

[@juandeloya4983]

I’ve always been a fan of Kicker subs in sealed boxes. Back in the day, I had two 12” Kicker Comp VR subs (01C12VR4) in a small sealed box (1.0 cu. ft. per sub) with loose poly-fil in each chamber. I had a Directed 1100d amp running them and I could play any type of music with no problem. The bass was loud and deep with no distortion.

Cadence FTW! All day!

[@dj4monie]

This is where box design is critical. You can go with a more complicated enclosure to clean up the uncontrolled movement of the sub which causes a more "loose" sound. Hexi Base has done lots of different ported designs that will blow sealed systems and infinite baffle out of the water in terms of control and accuracy. In other words you can get the performance in ported design that works with every kind of music while keeping the speaker movement controlled for tightened sound like sealed systems produce. Loud, accurate and not too big.

[@Bassotronics]

Not to mention folded horn, tapped horn, fourth order, sixth order, series tuned sixth order, series tuned fourth order, wicked one, clamshell, Snailshell, T-line, series tuned T-line, ABC Box.

[@evilinside5984]

Im well aware of who Hexi Base is, but "All" ported enclosures drop off below tuning, no matter how they are designed. Also "All" subwoofers, and "All" enclosures exhibit a different sound characteristic, that some people like, more than others. There is no perfect enclosure for "All" subwoofers.

[@wal]

There are a LOT of variables and the title of the video makes a generalization on the subject....It's subjective how something "sounds" but in this case I included the objective SPL data along with my subjective listening results. Would be different in another vehicle, different box, sub, etc.

I was always taught sealed enclosures for cars with trunks(coupes and sedans) and bandpass boxes for open vehicles(SUVs and hatchbacks)

[@MetroidChild]

Small "rooms" usually have insane gain, which describes the insides of sedans and pickups well, a closed box does the job well enough in these cases. For a wagon/SUV you can usually fit a quarter wavelength of around 40-50 Hz, meaning you can design your box to make use of that natural gain for SPL or a really wide band (or somewhere in between).

[@JoeIsCrazyWillman]

@@macbook802 and what would trucks, especially single cabs, fall under?... I'm going to be doing a center console down firing hidden sub. I feel like being downfiring is going to reduce some of the maximum volume level, and so I would want ported to accommodate for that? Also, wouldn't port design also factor into how clean the ported box plays? Having cleaner edges, or just no true edges at all, rather rounded off, carpeted air path, not too slim (not a long, slim rectangle, but rather more squared or rounded for slower airspeed along the sides). 🤔🤔

[@macbook802]

@@JoeIsCrazyWillman trucks would be bandpass. And a center console box is what I would do for it as well. When I say I was taught, its just what I've seen and heard over the years. I've never actually experimented with all of the variables. I do know that when I stray from what I know works, I'm almost never happy with the results. Pioneer head unit is a must, as much jl audio as you can afford is a must, bolting your box to the chassis is a must, expensive rca cables are a must, 100 percent oxygen free copper wires are a must, keeping everything as hidden as possible is a must.

Years ago (1994), I had a bass competition builder buddy of mine create what I wanted: TIGHT, fast 20hertz with 2 JL Audio Pro 10s. He accomplished this using BOTH concepts….I believe it was called a 5th order band pass box….a rectangular build with two sealed ends housing the subs firing into a center section port-tuned to the freq I wanted. WICKED response and depth for rock/metal! I ran this box for about a decade and then stored it for almost 20 years. Pulled it out and had it installed into the car I bought in 2016 and it STILL kicks ass. Ah, the days of HAND BUILT and calculated custom boxes…😍

[@KingMrBigE]

Sealed box provides a wider range of output whereas the old ported box is pretty much a 1 tone box... you lose all definition with a ported box but do get a higher spl at the resonance frequency. Another advantage to sealed is the power handling, its so much easier to blow a sub in a ported box than a sealed.

[@JasonWW2000]

Ported enclosures can have a nice wide bandwidth. Definitely not a 1 tone box. I think your mixing up competition boxes that are tuned very close to the vehicles natural peak freq. Like a vehicle that peaks at 50Hz and you build a ported box tuned very closely to that, say 45Hz-50Hz. That's a one note wonder box, but very high output at those frequencies. A musical ported box would be tuned to say 30Hz. Then you will get smooth response from 25Hz to 60Hz.

[@matthewstorm5188]

I never understood the whole idea that the looser bass of a ported enclosure is preferable for rock. Rock is most definitely ‘tight bass’ music. Even pop works better with a ported enclosure than rock. This, of course, brings up another advantage of sealed enclosures: they are much more musically versatile than ported enclosures. A sealed enclosure will work better for ‘loose bass’ music than a ported enclosure will work for ‘tight bass’ music. Yes, the sealed enclosure is not as efficient. But you can always make up for that with increased amplifier power (which is much cheaper these days vs 30+ years ago).

[@tjziegler8823]

I used to think a ported box built right could be pretty tight and clean but ive realized over the years that you cant beat the sound quality, tightness, and smoothness of a sealed box. Plus, if you want more spl but want sealed, get a double box or a larger subwoofer.

[@Person.555]

I would have to agree. At the end of the day, the pressure sucking the woofer back into its starting point when in a sealed enclosure is either there or not there (in the case of ported).

@@Person.555 Anyone over the years, SEALED UP an existing ported box with a zonky labyrinth or folded internal port with satisfactory results??

I'm running a single 15 in a 2.25 sealed and braced MDF enclosure with foam in the voids. I'm only giving it about 220 watts at the terminals, and anything below 24hz causes the windows, sunroof, headliner, etc to flap pretty dramatically. I couldn't do this with a ported 2.75 tuned to 32hz with nearly 800 watts driving it. And the bass hits so much cleaner. D&B music comes through with quick, punchy transients, but low bass stuff that carries also plays deep into the low 20s with a steep rolloff starting at 17hz. I was thinking of building a second one and driving the two with their own sub amp, but for what I've currently got, I think I would have to double up on mids and highs just to keep pace.

[@gr500music6]

In theory, porting increases efficiency and SPL at very low frequencies That's the point of porting. Sealed enclosures tend to have faster, tighter transient response because of the springy-ness of the captive air being compressed behind the woofer. This video confirms that. Thanks!

The old debate rages on... it's all a matter a preference and purpose... What's really important is having a properly constructed enclosure.

[@ceedavis5178]

I’ve experienced great sound from both types of boxes and bandpass. It depended on the type of vehicle I was using. I have two 10 in Alpine type R in a sealed box in my f-body hatchback Camaro. In my tundra, I have two type R in a ported box and they also hit amazingly with no slap or distortion. I have two 12 L7 squares in a ported box made by kicker in 88 caprice trunk that sounds great too.

[@arminag3827]

I have Alpine type S, i used to have a 30L sealed box and it sounded amazing but for a bit more sound i went to 40L ported box, it is still amazing the stop and go in Alpine subwoofers delivers top sound quality every time in most cases

[@terrysworkbench]

Thanks for posting this. I didn't see any mention of damping material being placed in the enclosures. Obviously none was in the ported enclosure. Though it was something we always used back in the day, we never took the time to measure any performance difference. Neither SPL, frequency response, or "coloring". The SPL results in this video were as expected. About +3db (or more) with the ported enclosure. I too also like the punchy bass of a sealed enclosure, but man, I like that bottom drop of a ported one.

My enclosed Kicker RT 12 sub just kicked it today . But Crutchfield made me proud. The amp I was running was a Rockville DB 12 RMS 500 watts . I loved the low bass sound with the high bass sound . Blown the damn speaker . I bought it in May of last year . It comes with a one year warranty so I'm so happy Crutchfield is honoring the Kicker warranty. I would go bigger but my 2010 Chevy Silverado crew cab needs space and that's why I need the low profile speakers .

[@Jason-dy6qy]

There's so many variables, I love deep and low bass, but I listen to such a variety of music that I have found sealed usually is the best route for most. In the end it's just whatever your preference is. Plus your budget, setup and so on. As long as you're bassin' it shouldn't matter. "Bass a holic" for life!

[@underconfident_asmr]

I won't pretend to know any better, but even as a kid I loved that instrumental electronic "bass music" such as Bass 305, Techmaster PEB, Beat Dominator, etc etc. For that super low sub bass, I always felt it sounded better out of a sealed box. The way ported boxes make the excursion appear harder and more intense upon that cone, I feel like it sounds dirtier somehow and may even shorten the life of the sub. Again, I'm sure I'm totally full of it with that thinking, but I stick with sealed.

[@Jsims111]

The excursion of a sub in a ported box would depend on what the frequency the port is tuned to and, what frequency the sub is trying to play. The closer the sub plays down to port tuning; the less excursion the sub will display. That will happen until the subs plays frequencys below port tuning; which will cause it to "unload" and, then you will start to see lots of excursion.

I never knew this a debate honestly. Sealed is for deeper,tighter, more accurate bass and is better for Sound Quality builds. Ported is for trying to be as loud as possible. I’ve had both. I prefer a large sealed box over ported and I listen to everything but mostly rap/edm.

[@hotdog9262]

[@benzee1]

I've always thought sealed sounded better and hit better.

[@20060270]

If you wanna listen to rock musick the bass drum sounds more realistic with a sealed box. Any genre that requires musical instruments will sound more accurate with a sealed box, music made by electronic devices may give you a better experience with a ported box but you must be aware that what you are listening to is not what the artist heard when he was recording it. I would only use a ported box for a home cinema, justo to feel explosions and other effects in my body. But other than that, if you wanna listen to music as it was heard by the artist that recorded it, sealed is better.

[@Russell_and_Rosko]

I was a ported fan until I put together a clamshell isobaric two 12" mounted facing each other...the depths this box can reach in this isobaric configuration are absolutely incredible (2.2 cu ft for two twelves) considering the subs are under powered and plain Jane ancient diamond audio drivers. I've had the same box loaded with a single driver with more power and the isobaric isn't as loud but it's more defined and it reaches deeper. There are times where ported sounds better for certain music / movies, but for most non synthesized music, sealed with a little more than rated power is a good starting point.

[@wal]

@hifivega did a build with (2) 12's in clamshell ISO with Savard Pro subs and it was incredible. They sounded amazing and the box was cool as well with the acrylic. kzbin.info/www/bejne/nHvKmqdjjKqBj7c

[@Bassotronics]

Awesome comparison. Next: Passive Radiator

[@Red2l16v]

For the size of the sealed boxes you can fit 2 small sealed boxes. Since power is cheap now and woofers are reasonable a pair of 12s sealed will play as loud and sound better than a single ported. Also the cost of the sealed boxes are a good bit lower than a properly constructed ported box. So overall a win/win.

[@-108-]

Better yet, sealing a *properly sized* ported box will give you a better result, as the enclosure will be larger, allowing the driver more movement without the sloppiness of a non-sealed enclosure.

[@wal]

While I was testing I had the same idea....could've fit 2 of those sealed boxes in the trunk. This "trunk" of the '37 Ford is not much roomier than behind the seats of an old school "extended cab" pickup

[@Coolness18304]

I remember old school kicker comp being better and louder sealed. Probably the best sounding sub in my opinion

[@Grommet2007]

I use two 12" drivers in a sealed enclosure for my car audio subwoofers. If I was going to use one 12" driver though, I'd probably go with a ported enclosure, tuned to take advantage of the car's cabin gain to get the most extended response. To me, the tests with the ported enclosure actually sounded a bit cleaner. There was less distortion, and this was visible in the app that you were using to take the SPL measurements. Less distortion = better "upfront" bass. A sine SWEEP with a freeware software measurement tool like REW and a good mike will confirm which of those enclosures is better at minimizing distortion.

[@-108-]

A sealed enclosure is always going to minimize distortion, as it limits movement of the driver element. It's simple physics.

[@Grommet2007]

@@-108- Actually not quite true. One of the advantages of vented alignments is the reduction of cone excursion through the passband (from Fb upwards) for the same output level, compared to a sealed alignment with the same driver. Once you go BELOW Fb however, the sealed box exercises better control over the cone's motion.

[@simon_a_s]

Here's some information for those interested: With sealed you basically trade lower linear distortion for higher non-linear distortion. By linear distortion in this case I mean phase shift and the derivative of this means lower group delay with the sealed box. With a vented box it can theoretically be compensated for with a FIR-based DSP-unit but would require an immense amount of calculating power (taps) to have necessary resolution in the lower frequencies. Most of the difference we hear between a sealed and ported enclosure is due to the frequency response. EQ the boxes the to the same response and they will sound similar generally. Vented boxes are indeed more efficient and can be far louder at (and around) the tuning frequency of the enclosure but will require a ton of power to do so. At the tuning frequency the speaker excursion will hit a low point and the air velocity through the vent will be at the maximum point. This allows for for SPL without running into the excursion limits of the speaker but it still needs to operate within thermal power levels. The lower excursion of a vented box lowers the non-linear distortion (harmonic and intermodular distortion) which cannot be removed with processing. A speaker enclosure always have abide by Hoffmans law, in order to have greater low end extension and high efficiency the box needs to be larger. Nothing comes for free. You can run sealed, vented, bandpass boxes and even other exotic box types in a SQ system and make it sound good. In a car it's often space restraints, acoustic issues and processing complexity that limits what you can do. I prefer vented boxes in general, not all drivers is optimal for vented systems though. For infinite baffle or sealed boxes it doesn't matter that much, they are very forgiving. Especially in a car, you get a lot of output for free in such small space. Generally you want low Fs, mid to high Q and high Xmax for sealed. In a sealed box the amount of air it can move is directly proportional to SPL, in other words (cone area * excursion).

[@bytchslappa]

It might be a further idea to test the sealed enclosure with polyfill installed (the white fluffy material) this not only tricks the sub it's in a larger space but also removes a lot of the sound the enclosure makes itself further cleaning up the sound quality.

[@jacobmathews-xo4ov]

Polyfill has been proven to provide no noticeable positives and more then likely negatives in most cases

[@inglouriousmofo]

Yup and adding no rez or dampening material helps. I built a 12 box and find just screwing it together instead of brads helps keep it solid and while Im sure a bit of bracing would help Im fine with it and it sounds great. Being ported helps too instead of the pressure bowing and bouncing.

Also, I still find the 1% THD test to be high THD, because we were all looking for amps rated lower than 0.09% THD.

The box should be around 45-48 litres (1.6 cu feet, smallest possible for the sub) - with some foam lining in it for the oomph - but works as intended!

It’s generally known that ported is louder and “boomier,” and that sealed has a tighter, punchier, and more precise/even frequency response curve. It follows that SQ peeps may prefer the sealed and SPL peeps like the ported. Having said that, the ultimate test is one’s own ear. Great vid, though I wish the boxes were the same size to control better for that variable. The boxes had a pretty substantial volume difference.

[@BrandinHutto]

Frequency response measurements would've been most helpful, perhaps comparing them (via overlay) to modeling software results (without cabin gain) to determine the effects of cabin gain, then using that information to determine an ideal F3 and Qtc for a sealed system in this vehicle. Then discuss low -pass slopes and crossover points. Doing this would partially demonstrate how to properly select and integrate a subwoofer system in a vehicle. Thanks for posting!
