watching your old videos, so much information learned… this is gold

I like the way you teach better then the professionals. You get to the point. No fluff no pass.

When I was young hanging around my cousin he always had sealed boxes in all his cars and they always pounded hard I always like the sound of a sealed box

Dude. You are SO down to earth with everything you talk about in your videos. I find myself to be technically savvy when it come to audio principals, but I love the way you explain things. It gives me ideas on how to explain to others who are not so savvy. Another excellent video!

Been doing car audio for 10 years but i still love listening to this and expanding my knowledge even more

I’m glad u’r talking about the back wave being involve in ported. Not many talk or know about this

I have sat through lectures both at undergrad & post-grad levels, seminars, technical meetings etc and when I tell you, MB you are an EXCELLENT teacher. Straight to the point, no fluff and humble, common qualities you find in all Subject Matter Experts(SME’s)

I am just now getting into car audio. You explained this so well. I have a sealed box now and I am going to switch over to a ported enclosure.

I like the way you explain things in your videos. Makes it easier to understand!!!!! Thank you.

This man got a PHD in music

This is a clear concise explanation of ported vs sealed. Good video. Thumbs up for me.

I’d have to hear ported in one of your custom boxes to be convinced. From my experience the bass hits lower notes inside the car with sealed but the bass from ported hits lower notes a few feet in front of the car.

Glad I found you dude knowledge is king

Absolutely true info. As an example when we first started in to SPL comps, we had a Chevy Astro van with 12, 15" JL w0 each pair in a 9 cubic foot sealed box. (Suggested by JL) Went to a comp in Vegas and hit in the mid 140's. It hit low and mean setting alarms off for blocks. After that comp we went to a ported enclosure with a single MTX RFL in a Yugo and did constant 160s tuned at 63hz. The Yugo sounded like crap bur was loud, the astro van sounded clean and mean. Each box design serves a purpose. As Ive aged I tend to like sq and sealed boxes myself. But still like a well designed ported also.

You are an amazing teacher I learned more in 4 of your videos than I ever knew before thank you so so much brother

been in the subwoofer game 20 years I'd consider myself very well educated with all things car audio. you did a excellent job explaining this. anyone watching pay close attention he's droppin info that most ppl do not understand and will set your audio system above other ppls systems. it's not all about power its about the correctly built box for your application. typically ported run very well in suv or a car with a back seat that goes down typically they don't perform as well in a sealed trunk environment use your time and energy building out what's best for your application that's the key not haveing a powerful sub or amp. additionally I see way to many people running CCA power and ground wires... don't do this if your serious about your system you should be running oversized high quality OFC copper wire with high quality terminals. and please stop grounding onto a painted surface it will never work correctly always bare metal then protect that connection with a sealant to prevent future issues. no matter what how big your power wire is your always limited by the smallest power or ground wire in your system. upgrade them all for optimal power flow. all these things will put you on the next lvl

Bro you know your shit! I appreciate you sharing your knowledge!

Love the knowledge, keep making videos God bless you

I feel like we just met, smoked n chatted a lil bit. Good knowledge g

Keep coming with the knowledge!

U explained this way better than all the other videos I have seen. Thanks

😎😎😎😎 Awesome Man. Great Video. Thanks for sharing. I'm Old school and love Power and Ported

Loved the 33hz video...its the magic number....I call it that Tony Dorsett tuning ...I'm old school

Sealed boxes make you feel that bass in the pavement 🤣 setting off factory car alarms.

Great information that the new jacks need to listen too...

Great video.. You answered all my questions

Thanks sir this was very informative.

Like that plaque behind ya! and you bud! Merrry Christmas mb:)

Can you please do demo on the DB g5 8” sealed vs ported ? I have a 2017 Toyota Sienna with a 12” bravos sub running off a zapco reference 500.1 I wanna use the same custom enclosure that’s in the rear drivers side where they would have the option 8th seat and run it @ 2 ohms . The info you give is really informative and since I did a search on the db G5 sub, you really got me hooked. Thanks in advance my man coming from Ontario, Canada

At this point you my Uncle and I'm your Nephew. I'm sending all my questions to you cause you know how to explain things the way I understand!

Great video man I like the way you teach man I'm looking to start building enclosures and I'm trying to learn all I can because I'm a newbie but if you could send me some stuff I should read or watch it would be gratefully appreciated Sir, God bless and may you and your family remain safe🙏

Ok you are 100% the Big BOSS at the sound game bro you are audio subwoofer professor

I really like a sealed enclosure with extra juice for the low end extension and quality of sound reproduction. I am willing to sacrifice SPL for sound quality and depth of reproduction. Great video as always.

All this Jalen Hertz talk, got me 🤪

I already knew the differences but you do a great job explaining! used to be all bout that SPL ported boxes for the win but recently I hate the boosted and lacking areas so I made a big sealed box for JL w6 12 v2 and mannnn this thing gets loud and low and it’s it’s SMOOTH every bad note hits the same and it’s all loud!

Great explanation

i got a t2 power in a sealed mdf box its like 50 or 60 kgs a fkn love it the speed and articulation is a nother level compared to ported and it doesnt shake the car so much

@MBEnchlosures LLC one thing I was expecting you to say, sealed typically is smaller volume versus ported. That can be a real consideration at times. It's a different conversation, but I don't hear people talk much about passive radiator setups. I really really like it. You can get the tighter higher frequency response of a sealed box, and the added efficiency at lower frequency of a ported box. I've got a 10" that plays lower 20 Hz area with authority. Very musical box design.

Any links you might add to the video description? I'm very new to this and I could definitely benefit from some good literature to go along with all my KZfaq research! Love your videos! I have a whole lot to learn yet but I know I'm gonna upgrade my alternator and/or add another plus another battery and... well everything I can do and save to plan and build my dream system! Thanks!

Sealed box hit hard ASF i rather have a sealed

This was an excellent video well explained. My question would be more for a home theater application in a small room. I have a 12x12 room. Which in your experience would perform better? My listening is split 50/50 music and movies.

Your videos inspired me to build my own box (10" Kicker L7 under seat) recently. I still don't quite understand port tuning that well but trial and error got me through it. Thanks for making these videos!

Can you do a db test with the 8(S) in a sealed box vs a ported box. Would be a great video and we don’t get to see any videos of sealed enclosures from one of the greatest sub enclosure designers.

Just subbed.👍

I have three stereo integrity SQL 12s and ready to run them sealed in my car. I know that loading a surface always gains a little bit of output ( like facing your subs upward toward the glass and a hatchback for example). What are your favorite ways to improve the sound of a sealed install? I can either wall them directly up to where my rear seats are and seal off from trunk to eliminate the back wave or I can put the subs all the way in the back of the car and fire them into a chamber that comes all the way up to the opening and then seal that off from trunk. Iron law states that more space equal more bass and it also helps with the subs being further back from the driver's seat as it allows the wave of bass to develop further. I have seen diagrams from professionals stating there's always decibels to be gained when loading surfaces with sealed enclosures. With the subs facing each other and loading onto the boundaries and the air mass in the chamber I can't help but think it will be a significant gain over just walling them up flush against the trunk opening. Ideas, opinions, it's basically three 12s in the back of the car firing into a v shaped megaphone( with a MDF floor and ceiling on top of the three enclosures) that's mouth opens up into the listening area. I can't help but think it's going to sound good as it will take advantage of the horn loading effect like a hatchback. I don't want to slam 3K of legit power directly into my back window in a coupe lol!

It really depends on the ported box every box is not the same I've heard guys using pre fab enclosures and they sound like garbage you absolutely have to have the correct volume with the correct Port area and Port velocity and you want at least 10 DB of rise and should have a decent frequency band for instance my average enclosure that I build will play down to the low 20s high teens and up to 70 to 90 HZ with 10 to 15 DB of rise

I have been debating on a seal or ported for my new duel 12 set up thank you. Seal it is

I like sealed boxes with shyt tons of power and alot of woofers over a ported box with less power and less woofers. I can feel sealed bass more and its meaner and cleaner and just is so earthquake, however, i cant ever buy the best subs cause those mega subs with like rediculous insaine xmaxx want a ported box... So im stuck with mid grade subs usually, but they good.. People hear me forever away still.. I think that clean bass note travels better than the ported even though its louder.. not sure , just seems.

I have a good question for you. I’ll be getting the Kicker Q class 12” 42CWQ142 sub in my 08 Colorado extended cab. BUT my question is if I would be okay running it in a wider flat box that would span the width of the back wall with the seats removed so I can have space to put groceries in behind the seats and still be good. So can a speaker box be not as deep and wider than normal and be the same as a more cubed shaped box an still play 30 hertz and be good.

I've only had ported boxes tuned to 33-35hz on my two kicker 12 cvr And my American bass xfls. Always ran them on my 800rms amp. People never believed me and I just tell them it's all in the box.

In regards to ported vs sealed, I think it all depends on where the box will be installed. I had a ported box in the trunk of my vehicle, and it sounded nice. Yet, when I took the same setup, and moved it to the back of a Tahoe, it didn't sound as nice. Going back to the ported box in the trunk to my car, it sounded nice, yet when I would lower the back seat (acces into trunk), it would hit harder. So I guess it all depends on where you'll install the box; I guess if the box and subs have more air. But in regards to having more air, the subs and box had plenty of air in the back if my Tahoe, yet they didn't sound good. It's still all a mystery. LOL

Lots of rms in a sealed is how I grew up. You’ll hear the difference from a cheap sub and a good sub. Country, Hip Hop, and EDM from a sealed. Not the hard thump but the warm thump. The thump that feels like it’s gonna drag you straight to hell.

Would it be a bad idea to put two vxf 15s in a sealed ground shaker box?

always come and reference your videos before doing a build. Such good information fam. Would anyone happen to know the resonant frequency of a 2012 suburban?

Im new too the channel, Had a few questions about my 07 Avalanche I want thunder but I'm up against the wall about the type of enclosure I want to build What type of box enclosure would you recommend to maximize bass I'm not a fan I'm not a fan of the down firing subs or the up fire Subs under the seat so would a midgate enclosure be the best setup because to me. it still looks as if the woofers are being muffled on a midgate enclosure What would you recommend?

Should i go with a ported or a sealed box in a trunk of a car ?

Which box should I go with if I want my back seat to stay up bc I have a ported box now with two 12 inch ds 18 subs 1200 watts each also a 4500 watt amp and there not boomy with the seat up only boomy with the backseats all the way down!!! What should I do ? Pls hit me back I need to find a solution you see like your well educated on car audio.also I have stock door speakers bc my car is leased.

Hey, can you do a video tutorial or just elaborate more on horn enclosures

Got question I get ready to run 3,18 on audiopipe 1800 what be best box

So I have a 16 cuft box with 4 separate chambers. 2 chambers are tuned to 36hz and are a slot port. The other 2 chambers are still sealed enclosures and I was wondering if I could use a round port on those 2 sealed chambers. So now they would all have there own chamber and own port. And one last question, is it okay to keep my 36hz slot ports and have the round ports on the other 2 chambers tuned to a lower number like 33 hz?

It all comes down to music choice and how you want your low end. Controlled punchy or loud and boomy.

I guess you can also determine your best choice between ported and sealed by the primary choice of music that you'll be listening to. Rap vs Rock/Metal etc.

Need to find the video on orders of the enclosures (if I am saying this correctly). I think I understand the differences but you can always draw new information from anyone.

👍🏾👍🏾💥💥

I prefer sealed all day every day!

I have always went torward sealed, but i listen to punchy fast music .. i wanna do b2 rampage’s in sealed in my 14 mustang . It would be nice to know i have the right box

I have 4 DD 8s in my truck. Not in a sealed box or a ported box but the best sounding enclosure you can have... what kind is it?? Hint, not IB either....

What are your thoughts on a passive bass radiator?

I have 85 el Camino I’m having a box built for it with four 8” Toro fierce subs, sealed, what are your thoughts on that?

I prefer sealed or infinite baffle for my sub. I’m all about that musical sounding deep rich punchy bass.

to be far sensitivity is measured at the fs of the driver

MB if on a sub in a sealed box is only getting bass from the front of the cone, why do a lot of people run 4th order box? A sealed box inside a ported box doesn't make sense to me and how is a 4th order louder than just a regular sealed box? I don't understand how it works. I understand 6th order and I was just wondering what was your knowledge of the my question. Love your channel brother especially the teaching videos 👍🏿👍🏿👍🏿

I got one T1 12 gonna run it at 800 rms 2ohm Manuel says use 3/4 mdf can I use 1 inch instead

Why do we not see more band pass boxes anymore? Wouldn’t that be the best of both worlds ?

Whats a good dampening factor for an amp im looking at the B2 audio rage 2500.1 it has a dampening factor greater than 400 signal to noise of 95db is that a good choice of amp

Could u talk about xmax. I have DD3512s esp with 17-18mm xmax but they have better output compared to some subs with a greater xmax

MB why do you prefer ported over sealed?

I have a question in a single cab truck with a small space would u recommend ported or sealed 2 w6 12

I got a question though g. Why do subs sound at their loudest when they’re back fired close to the trunk? I get the loudest and most physical with every box I’ve messed with like that. Even compared to downfiring towards the spare

Have you ever tried anything with a pr

A ported box do roll off after tuning. But it will still be louder then a sealed enclosure about 3/4 of an octave below tuning. A correctly designd ported box i almost always superior. In my opinion a sealed enclosure is only better when space is limited, or you want your subwoofer to play below 20Hz. It is also much easier to build and design then a ported box.

how much rms for a under a seat for a sealed box 10s

Why do you like ported over sealed if sealed can get as low and is more accurate?

This a great explanation 👏🏾

I have one DC level 6 18 (and I have 2 10 inch ZV6 ) Which has the capability of getting louder so I know what to put my money into.

What about ported vs sealed when it comes to midbass/vocals

I'm having problems with my dB 300, 4ooo wats, 1 ohm.. I have Two other dB 1 ohm at 2000 wats. 1000 rms. How do I drop the two dB to a two ohm load. I keep clipping an my gain is barely on.. Could you help me out. I would be vary greatful. Many blessings..

Clicked real quick cuz I trust a black man

sealed is better but these box makers make money selling ported because anyone can build a sealed box. ported sounds bad. Large sealed is best. my go to is two 15s sealed . a box designer has nothing to say to make a sale but with ported they talk endlessly bout tuning most say a box is tuned to 32 but its rob more like 55 hertz

Here to learn and boy am I learning

i have an old sony hifi system from the early 90s that uses a quasie-sixth order series tuned bandpass. I didnt know what that type of enclosure is until now. the original sony woofer rotted so now its just a cheap lanzar sub. who ever designed that back in the day must have know a thing or two about tuning enclosures.

what do you think about Skar Audio?

You should do motorcycle audio

So if my box is tuned at 36hz where do I set my subsonic?

When are you gonna start on your son's truck build? I'd like to see the journey of it if possible

What do u think of Rockford Fosgate subs

Is there a difference between sealed and banpass?

ooooweeeee wifey was one more question away from a DV at 6 min 30 secs

I have a ported box tuned to 38 Hertz with a 12

What is the formula to tune a sealed section of a 4th order to lower my drop off frequency?
