Sealed vs Ported Demonstration by Audio Xperts using SPL meter to show output differences 

Yet, if you go to a local speaker shop.... This represents a lot of the sheisters out there.

It's colonel sanders and it's bowling night.

Shit man words taken out my mouth

Well obviously 🤣

I'm hella weak 💀

Sounds like the ported enclosures you have used are poorly designed to the subwoofer.

You know ..bigger the box bigger the bang sealed hits #HARDER DUH....👍🏽

@@AaronClinton Nah. POrted sunds wack

@@mr.b3168 then you haven't used a properly designed and built ported enclosure

TSBGLtd all true though i understand the use of damping in a sealed box (usually poly fiberfill @1lb per cu. ft)is to present more virtual volume for the driver by displacing the air and making it more compressible. This has a side effect of excursion control. Also supposedly controls high frequency distortion created by the box it self. Myself I always liked sealed boxes. easier to tune and sound good with a variety of music.

He said both

Maybe they serve sandwiches too.

@@filesshared9431 That reminds me to go the shop and get some fuckign food finally

I wouldn''t say huge. It definitely makes a difference, maybe 1-2 DB at most. That will be another video to produce to measure.

+AudioXpertsVacaville in home audio where you place the sub makes a hugeee diff in output. the shape or the room will change the best place for sub. there will be dead zones in rooms where you will lose half your output

+oyobass So does using different subwoofers in a test!

+XcLuuSiiVe absolutely. Stop by for a free vehicle inspection so we can work with you on a design.

hey i live in Vallejo i want to get a custom box made for a single 12 inch(400rms pioneer) in a 2013 Hyundai sonata,was looking for a stealth box feel so there's still some trunk space.i was wanting to know an approximate price range,get back to me if you can.

I agree..and then throw in box placement..my sub box will gain or lose 10 db depending on angle and space from the back wall

You didn't pay attention to the video guy

+nmarcano3 how so?

CLEARLY stated that the subs were the same.

+nmarcano3 what is implied and what is a reality are 2 different things. even still, in the most critical comparison (same driver, same amp, same source ) the use of a SPL meter still makes no sense. of course everyone knows a ported box will be louder than a sealed box in a ideal comparison. But is that what we, as a consumer or a sound engineer should be striving for??? if that was the case, then we all should be driving around with Lanzar 18"'s in a universal bandpass box.

😂😂

Hahahhahahhahahahha

On certain frequencies not across the board play 10hz below tuning see what happens

Lol.. You didn't know this guy was in the USACI World Finals?

Which do you think would fit better in a behind the seat single cab pickup?

sound better, I meant

I also have single cab truck with rear window removed and 2 15s in a ported box wonder if sealed be better it's way louder if my doors are open

no doubt in the '90s I ran four sealed 8" subs with 1,400 watts and they hit like 2 out 4 of my 15" subs that got stolen

+Luke Connell That all depends on the port tuning. If you get a prefabbed box that is ported too high or is too small it may be loud in the upper bass range but seriously fall off under that. I will agree with your statement as long as the box is tuned low enough. I run a bit larger than spec sealed box for lower bass extension (at the cost of volume), but if I had the room in my vehicle I'd have a huge ported box tuned to around 32Hz

+DaOldSchoolRapLova96 Thanks and good luck to you!

😂😂😂😂

Colonel*

A kernel is a grain of corn.

he was wrong because he used a small $50 sealed basic box and put it up against a ported box that was designed for that sub. Had he used a slightly larger sealed box that was designed for that sub the 2 would've been closer.

U had that in a car

+Fierro Pariente ?

An honor seeing you here!

Did you really now? I love seeing dumb videos and dumber comments

Fuck You He won the deathmatch.. His subs were smokin at the end of the competition!

Thats not hard to do with USACI ..

Fuck You know

James stranger i agree bro . im running 2 10 inch old school ppi subs sealed box running off a crunch pzx750.2 amp in a honda van lol sounds good nice punchy bass but not loud loud as long as ur subs aren't distorting your music sounds loud and clean

Kicker comps where nasty back in the day

The old school kicker comps black cone with a dude on a horse on the cap were truly awesome subs. I had 2 kicker comp 12s in a sealed 1.75 cu/ft box per sub... Pushed 75rms to them. Damn I miss those days. Love to find another set..!

Speaking in 15s for spl 12s won't put out the same spl as 15s

Baby Gotenks hmmmmm im thinking about getting a sealed box I have 2 15 cvx and wanna switch?

Elgallo Deoro from a ported box with two 15s just get a bigger box

Baby Gotenks im just gonna switch to sealed !

Or, do yourself a favour, and "deliberately BOLT two speakers face to face, (with just enough of a spacer sandwiched between them, to separate the diaphragms apart, to stop them rubbing against each other, as they move TOGETHER in either direction), making absolutely certain to reverse wire one across to the other (in series) as that way, the signal current FLOWS through one's voice coil, pulling it IN, whilst simultaneously flowing via the reverse terminal connection (of the other), which allows the same current to "push" one speaker's diaphragm OUT, with the other pushing IN equally as hard, to then pull each other the other way, (thus avoiding EITHER speaker from completely bottoming out, or extending beyond the magnet's core material when at their maximum extensions, driven hard). Result.? NO actual compression of air, being able to occur DIRECTLY between either speaker, but BOTH act as if ONE SINGLE DIAPHRAM, which can thus simply be mounted in a free standing (single) sheet of particle board placed ANYWHERE - even in the middle of the room, such that the backs of BOTH speakers, send the complete sound wave, away from each of them in turn, as the COMBINED dual diaphragm pulsates equally hard - in BOTH directions as the sound is played. Then and only then will a PORTED versus an UNPORTED system be truly comparable. Why ? Because either works just as fine as the other (same SPL levels with both systems) - as it's then NOT about the speaker's ability to DRIVE in just one direction only, but in both in & out directions, ported or otherwise.

Well said. Thats why I have 2 subs, one sealed and one ported, good overlap. I listen to alot of types of music and sounds good. Not that I have a 4 billion dollar sound system or anything, just entry level

+Adrian Paul Mind blown. I'd never thought of sealing one and porting the other in my regular cab work truck. Hard with one amp chained for 2ohms but I have several spares I could employ to be the ported workhorse. Now I'm wondering how my '94 mtx thunder pros would work with only 1.34 cubed air in the box.....

Neil Ogaard cool ;) Ive only got shitty BOSS 2600W 12 inch X2 and a boss riot 3400W amp, Go ok for the money but are seriously over rated out put specs.

Neil Ogaard oh also running them to 1 ohm off the mono block, seem to work ok. And they in a basic 1 cub foot box so plan is to make 2 different size boxes and port both to different freq. The ported is definitely louder

Bolt two IDENTICAL speakers, "face to face" (with a minimal anti-touching diaphragm/spacer sandwiched between them), AND also deliberately "reverse wire them" (in series with each other), to create a SINGLE ACTING push/pull diaphragm where each diaphragm works with each other, in either direction, so that you then have one that is ALWAYS sealed, whilst the other is always unsealed, (fitted into whatever sized "sealed" enclosure you want them placed inside, or simply don't have any enclosure at all, and thus put them either side of a single piece of particle board, which can even be free standing "somewhere" - away from other surfaces.That way, you will have a dual acting in/out diaphragm action, whereby neither speaker bottoms out, without the other drawn out of it's magnet core's slot. Basically meaning that neither will effectively bottom out at all, no matter how hard it's driven (until the voice coils pull completely OUT of the core magnet's slots, thus distorting & destroying the speaker voice coils, that won't then fit BACK into those slots). p.s. Then any amp will do the trick, (as even a truly cheap-as 300w sounds great) with a push/pull system - unlike a single speaker driven in & out, on it's own.

sealed boxes deliver the lowest bass,, ported boxes have a Bump as you will, or an increase in Db at the PORT TUNING frequency,, but will fall off sharply after that frequency. The clearest tightest and lowest is a sealed box,, all with the proper sub for the proper application

what you mean?

The guy is pointing towards a ported/vented box half way up the wall and calling it a sealed enclosure. Shut it off right there. If you can't identify an enclosure then you shouldn't even be trying to sell or recommend stuff

Dell Jr u pay 850 for a 15" fosgate power t2 and i shut two mtx 9500 12's the fuck down js and i dont even have a power cap or extra battery stock alternator and only running four gauge wire and a punch fosgate 1000.1db

And ill shut down your t2 with my x12 js...

When properly built, no box is "better". You chose a box based on what you want from it. All box designs have compromises and advantages. No box is better, just different.

+WIZZIEDEE4LIFE Thanks for the feedback!

True lol. If only bandpass boxes worked with every sub out there, and were not a pain in the ass to build correctly.

+Alex Alvarez I love bandpass boxes in certain applications they tend to be play a lot of live music better as far as kick drums that sounds like that and you don't hardly ever see anybody with them most people I talk to laugh at bandpass boxes but that's because they don't know any better

+ Alex Alvarez They laugh most likely because they are probably used to seeing the same old cheaply made bandpass from pyle, pyramid, etc. I had a MTX TB12 Bandpass (single 12" 200w) on a 150w rms amp back in the day and it would flex the roof of the car, and shake the mirrors as well. I've seen Dual ( I don't mean the brand) 12" Cheap Bandpass and it just sounded like loud mid bass resonance and port chuffing.

Yeh in the cabin is best I miss my hatchback 😭

Silkmaster4200 box type has very little to do with being heard down the road. Displacement, driver efficiency, box design, power, and port tuning for ported boxes are just a few things to consider. Not to mention vehicle size, design (hatch vs suv...), Vehicle resonant frequency.... Just too much ignorance in your statement

Angel Estrada hell yeah sealed any day over ported I like both but sealed just sounds better basss

Accuracy, yes. Problem in have with ported enclosures is that they fall flat on the lows especially 30hz and below unless you have a custom built one tuned at a lower frequency. But they are quite loid and boomy at 45hz. I once bought the kicker CompR dual 12 box from best buy and lows were virtually non existent 30hz and below. You could hear them bottoming out but that was it, yet my one old school CVR 12 in a sealed enclosure put out way more low frequency bass, shook the heck out of my seat. Didn't have much higher frequency output like the ported setup did but killed that kicker loaded box with the 2 CompR 12's. If you have a ported enclosure tuned at a low enough frequency it can slam lows at 20-25hz but sound quality and accuracy go out the window. With a sealed enclosure if you want more lows around 20-30hz you can achieve that by going with a larger enclosure assuming the subs are the same for comparison purposes. Also cheap subs won't hit the lows regardless because of physical limitations like excursion. Cheap ones don't have near the excursion as a good one. And to hit those super low bass notes you need that excursion.

D Anderson Depends on the impedance of the coils and your amplifier and electrical capability.

Just not the lem-08... great output for a 400 watt 8, but at what cost.... just put a 12 in a matched sealed, same output, better sounding.

lmfao, I thought the same thing and then remembered he was a chef.......

Low ported subs are massive size of a fridge. In a car I'd go sealed. You don't need massive db output, and smaller size and room gain will help.

That's so true: Ari Reid A 300watt amp can produce in excess of 126db, (whilst running at LESS than half it's rated output power), when a few simple rules are applied. BALANCING the Amps output reactance, to the implied reactance of the connected speaker LOAD, is what transmits the highest level of sound. Not the enclosure, or how MUCH current one can force through the voice coils' winding.

Quix Kiwi Could you please elaborate on this some more

Yes I could, but would you actually "understand my answer" ? Oh who cares if you can or you can't. Here's what I will state. THE OBVIOUS. As the operative word I used before - was: BALANCING As THAT is all you really need to understand what was said.? Don't consider this to be a useless method of "automatically leveling" the resultant power output levels of TWO speaker channels (in a bog standard 2ch stereo setup) as that NEVER balances anything, except the perceived listening "line" between two speaker positions to thus be causing the (resultant) "summated" MONO to then "appear" as if at a point ? About midway between these TWO speaker positions. . Balancing is actually something done in reference to the "making of the same" with regards to what the Amplifier see's as a load , as against what the speakers see as a "driving" supply source" Two speakers will NEVER provide a balanced impedance network, for any two channel "stereo" amplifier (Where stereo means MORE than one, which by definition ALSO refers to there being actually - MORE than two, rather than JUST two speakers). As to correctly BALANCE the output of even a "cheap as" (low powered) stereo amp? Be that a TWO CHANNEL AMP - or the most expensive multiple channel digital amp model available ? (which is "able" to supply any number of speakers, within the impedance "ratio" range, that the amp's output's can handle) Thus to understand BALANCING ? One must in the first instance UNDERSTAND what you intend to balance. If it's just a single listener's (own) headphone's LEVEL of loudness, in comparison to the output power setting, (of the OTHER headphone in that pair of headphones)? Then all you need to do - is "position the perceived" center=summation positioning, (not a real.central mono) to exist somewhere halfway between the other TWO speakers. If however you wish to CORRECTLY balance the output "loading impedances" Direct to what the ANP can successfully drive OUT to the speakers connected. (without undue clipping, heating or other weird sounding distortions) YOU WILL NEED TO UNDERSTAND HOW THE MUSIC WAS ORIGINALLY RECORDED, (by even as few as ? JUST TWO MICROPHONES.). When the "sound area" was created across, (to even be recorded for YOU to "play-back") And thus to be "heard back later" as if YOU are still being, ? Within a generally considered OPEN dispersal area, of a THREE dimensional "horizontal plane" of sound. AS WELL AS HAVING (at least) TWO OTHER THREE DIMENSIONAL "PLANES" OF GEOMETRY Comprising "not" just a WALK-BETWEEN line of sight/sound between TWO speakers.? But "across, around, up/down/over inside-out &/or otherwise" sound planes (firing sound OUT in multiple directions as if being a LIVING PART, of whatever actions are being done) As the inclusion of trillions of perceived generated beam pattern's are what makes this special, in the way it does now also ACTUALLY EXIST AS, in open space around as many speakers as you wish to include "And thus (again) working environment areas, to be creatively positioning's thereof, (all sound contained in just such an outdoor event) to thus be recreating sound between NOT JUST TWO, but as many "all_around"©™ speakers as YOU wish to include, in your "surrounding" sound replay/recreation system. To ensure correct SPACIAL (3D, 4D and 6 - 9+ channels) listening pleasures too. Whereby that is what is actively obtained, to thus be what drives UP the standing waves, to force the radiated waves to "appear" as if all louder, (as if it's the correct - high powered amp's output), to thus "arrive" at what would APPEAR, as a total surround effect, when in fact, it MAY WELL BE, just a silly wee recorder/player's "recorded sounds" - of the artist "painter".? ONLY THEN will a thought hit you (inside your brain),? Such as to why all of that "is this", And thus (?) WHY does it sound "better" and also EXTREMELY LOUDER - than what you initially "showed" here as if it has "very loud sounds". See ? Did you understand ANY of that profound statement ?

Quix Kiwi First of all, I was not being cynical at all. while I do appreciate your response, You were correct in the fact that I understood little of what you said, some but not much. I do appreciate quality sound over total loudness and was hoping you would try to explain how to achieve a better balance in simpler terms, if that's possible.. it may just be beyond my level of understanding, But I thank you for taking the time to try to explain. Perhaps you might know of a link that could explain in a simplified manor so I could attain some knowledge of achieving a better balance. Thank you.

Sorry about the abruptness before. Yes, but it would be far better for your understanding, if I just tell you (and everyone else interested in this subject) to "contact" your local electricity supplier, to ask THEM to explain all about load shedding, load balancing, power factor control and distribution network control systems, of ANY 2 phased & 3 phased power supply systems (which effectively are ALL that a 2ch stereo audio systems are anyway) to decrease the AMOUNT OF SUPPLY POWER NEEDED, to force "usable wattage" (output power) into an unbalanced consumers premises.!!!As an unbalanced (incorrectly loaded) consumer's premises, will actually WASTE almost all available POWER (wattage) from the supply generation point, just to create an ineffective "minimal wattage (power) seen at the load itself.Hence those who KNOW "all about" how costly it is to be paying huge dollar figures, for expensive HIGH POWER amplifiers, also know diddly squat, about WHY their uselessly low powered speakers, are sucking all that power from their expensive HIGH POWER amps, without creating any "really efficient" sound VOLUME.? As volume in a 2 dimensional (or even a 3 dimensional) sound field is an "incorrect term." THERE IS NO VOLUMETRIC CONTENT in two dimensions - only LOUDNESS. Loudness isn't a good user of wattage (power), as LOUDNESS just wastes power. In fact a small increase in loudness requires an extremely massive waste, of the available "supply wattage" (from the amplifier itself), to gain maybe 1/2 a dB increase in loudness at the two speakers. .... to be continued below (re: Now... )
