Professor MB!!! Man I have learned more watching your channel in the past 4 months than i have learned in my past 20 years of trial and error. We appreciate your intelligence and knowledge in the community bro. Please keep dropping gems.

I am so glad I found this channel, I have learned so much. I know this is a older video but Thank You MBEnclosures for taking the time to explain things such as the T/S Parameters, and using two different subs to help prove that the way a sub looks doesn't necessarily mean one thing or an other. That goes for most of your videos, how you explain things makes it a lot easier and fun to learn and remember.

I started car audio a lil bit ago and ill tell you this dude here will give yall the best information the knowledge that you need to know what to get how to run it and how to make it sound good. This man should have wayyyy more subscribers he a goat!

That Id is the best sub I ever heard. very detailed and sharp. anything close to the perfection of this sub.

Great video 👍👌 and thank you for taking the time to give a break down of the difference .

Too funny. I was just looking at the ID 8" or 10" for my build. Had others in mind that had more bulk, surround and higher $. I wanted accurate, sq with some lows. Just reading the parameters I was like "the ID is perfect for me!" You just confirmed that 1000%. MBE Guru! 50/50 on sealed v 4th order just have to get the cabin specs. 92 full size blazer K1500. Wanted lower power, better output and accurate base. Either 3 or 4. Greatly appreciate the knowledge you openly share. You are KZfaq's greatest by 100 mile!👍

16:10 This was my eureka understanding moment that described sealed vs ported optimized subs. Thank you dude

Very good video, learn something every time I watch a video

Preach!!!! GREAT video, Sir!!! Another one of those dealio's Imma have to watch again for sure hittin' pause so I can take notes! See this is how I have erased what I thought I knew, and have been relearning especially for what I have in plan for my very near future! To be known in the near future! You explain it very simply in a manner in which is comprehensive to both the new guy and seasoned veteran! I will have to bookmark this to come back to to jot down some key points you made in reference to the balances of the soft parts and the M/F and so on. I just happen to come across your video I watched earlier and said yep time to watch a few of these!!! All Respect!!!! Oh, skinny guy is EXO, he has come so far in this industry. I have seen most all of his videos, boy good! And he has approaches that are also simple and to the point without sounding like a cocky know it all that knocks others or products, etc.

Another great vid. Thanks MB

Good info! glad I found your channel

nice video man ive been waiting for vids like this for years i understand all that youre saying

Mannnn this guy is good an knws his info!!! An speak to were i understand him💪

Good info MB the truth on this will help us get the most out of our $$$ and the products that we buy somebody pay this man

Class in session folks listen up!!

Yessir I can't wait to see what it do in that horn enclosure

Good video. Cerwin Vega used to have some of the highest efficiency woofers due to their tight gap and light cone assembly. Maybe they are still that way. The only trouble is that with a tighter gap, they are more prone to damage due to slight misalignments. There is a tradeoff with air velocity across the coils too with different gaps and different venting techniques. The windings design are also important in regards to wire gauge and number of windings to determine magnetic force and mass. The speaker engineers have to balance a lot of factors to get a product that sounds good and usable in reasonable sized enclosures.

Great video there 👏👏👏

Great video. Thank you

Love this older video..I need as much knowledge I can and MB brings it 💯🤔 because I would think the same go for the biggest but not always true...nice

I fkn love watching your videos

Didn’t realize that. Thanks for this one.

Dam good video now I can understand what everything means and can pick subs and more box options and match amps I like these videos more you need to do more on other brands

This right here is why the JLW7s are so good, along with a properly designed enclosure and power. Same goes with the Sundown Night Shade series!

Appreciate the wisdom 💪🏾

Excellent video as I was just looking at new subs wondering how all those numbers related to what I want.

Hello. How are you? Can I call you Professor MBE? No pun intended. You are an excellent teacher of car stereo. I have been a “shallow” enthusiast of car stereo since the late 80s and still have not learned a bit of what you know about this in-depth game as you do. I have run through a lot of hardware. But I feel now that I have finally heard and seen “car stereo” theory in simplification and example from your content. Now I can try to give it yet another shot based on your clarified videos. Although I have to watch videos like this one several times before I catch it, I will commend you on your highly inspiring content. That’s why I call you the “Professor”. You just need a chalk board behind you and I can really get the just of what you are explaining in one dimension. I have seen deeper content when it comes to car audio but not as simplified. Please continue to break the game down. You do fine work on your enclosures as well. I think you have changed the game. Peace.

Man I can't thank you enough.

I just looked up the QTS on the kicker L7 12 Q class and it is 0.539 so that’s a pretty balanced suited sub for vented or sealed.

Videos are awesome keep them up. Could you do a video on ports and how you decided port size for an enclosure? How does port area effects the way a driver plays and sounds in a enclosure. I’ve noticed you use big ports in your tuned boxes when looking at box tuning software it differs on what’s recommended on paper to what you use and results from your experience. Thank you and keep up the awesome content!

Good info. I thought lower qts was better in ported and higher was better in sealed though

Dude the fact u have 0 dislikes and almost 100 likes says a lot. I’m going to watch all your videos in the next few days and will probably reach out to see if you will build me a box

My man! Lookin like LL COOL J !!💪💪

Love the video bro. 👍 new subscriber here

Just giving you a heads up Toro is making a 10in subwoofer and a 15in subwoofer thats coming out this month guys. be on the lookout.That only means 2 more reviews coming at yuh by MBE himself.Fingers crossed.there also going to be making mids .

Thank you so much sir. Can you do in future if you have the time.. Is better for SQL fan to go active or passive from you own experience.. You know like advantages and disadvantages.. And the end is it worth the trouble and money.. In your own point of view

I appreciate your knowledge that you put in layman terms for me to understand. I wish there was a way for the T/S parameters to be demonstrated somehow. I’ll be one of your subscribers that will need to watch this video multiple times. I do feel like I learned a lot from this video. Am I correct in saying that not one parameter tells the story, you have to look at multiple parameters and the trade offs to get what the sub has to offer? Ty

Good shit bro

I needed 3000 watts of power to hear this lecture....lol...very quiet...ty though

Salute!

Knowledge is power

Have you looked at EM audio subwoofers 8" and 6.5" specs?

Hey thanks for sharing your knowledge. I am from the Caribbean and new to the hobby. Loving your videos. Need some help in understanding something can you explain the difference with the following Sbb4 and bb4 QB3 and Sqb3 SC4 and C4 I am totally lost. I know these are alignment but are the enclosures normal bass reflex boxes...or 4th or 6th order

I hear this over years and years... It will sink in eventually, lol.

Most important: Always test your theories in the real world. It's the only way to a true understanding.

Do you repair subwoofers as in Volfenhag 12' 2500w DVC Subs?

The Audio Legion Maximus 12 dual 2ohm how would one find the ts parameters of this sub? No info on the AL website...

Love this video and some of your others but I can just barely hear you

How are two 12in Rockford Fosgate P3 VCR in a ported I have a power T1000-1bd pushing them

I completely understood everything you was saying about all the numbers and stuff.😶🤥

Reading from google of qts,the higher the number from 5 up needs an sealed enclosure sir..4 down better ported..a few have already said this..good knowledge on the subs though brother..

How about something small that will hit hard(boom) in a 2006 Honda Odyssey?

thoughts on stereo integrity ?

👌

What about a light mms and a overly strong motor? The nep 8s look crazy good on paper lol 91 mms bl of 14.8 on the d2 fs of 49 qts .48

What i'd expect from the bigger surround would be more xmech, not really more xmax

Some good subs for a sealed box?

Where did you learn this stuff

THe way i understand qts, higher qts is better for sealed boxes.. Old school bass with old subs way back in the day with sealed boxes had high qts... So lower should be better for ported. I think... somehow somethings backwards cause the other info i found was the opposite, im just trying to learn about it all...

Amazing how audio guys publish videos at so volume..

Those subs look like 6.5’s next to those big guns! Would my 3 10” subs sound better @1.33 ohms with 400 watts each(max rms) or @ 3 ohms with 1000 watts combined?

What’s a little ridiculous now that I think of it have you tried Rockford yet? Am I missing something

It's all about your enclosure

I’m new to the subwoofer game as far as trying to soak up knowledge and learn. I’m still extremely confused on how to buy the right Amplifier for a set of speakers

I read the opposite of what you say on the internet low qts works better on a ported box

Thing is everything ive ever read says lower qts is better for ported and vice versa so i can't just agree with what he's saying

Can u explain displacement in stupid terms for me? lol, what does it mean, and in terms of building a box like how do u use that 🤔 meaning is thay much clearance u need from the magent to the wall or port?

Tell me a good 10inch subs to run with

I think you are backwards on your qts rating.. Lower is better for ported because it has a stiffer suspension and higher qts means it has a weaker suspension, needing the sealed box air suspension to prevent over excursion. I think it's like .4 or less for ported, .4-.7 for either, .7+ sealed. Also a 4th order is a ported box.. I think what you meant was a 4th order bandpass, which does work good with higher qts ratings.

The one on the left is a hot dog in a hallway. Lol

Hahahaha i cried bro yo said ezo.....its E. X. O.

9:09 be careful what you're doing there You might get demonetized LMAO

In other words, most people are clueless! Including most installers.

09:15 I really have to grow up :-) :-) :-)

Love the vids...the audio is the worst tho...

Good vids. But… the bl doesn’t mean quite what you say. There’s more to it than just comparing bl to bl. It’s based on impedance. So it would be BLxBL devided by re. That would give you actual motor force. You are correct about motor size not being what determines which is better. So look up the re and redo the math. Might surprise you.

Looks can be deceiving

Wow just proves that the looks are deceiving. Got to get a sub that matches with the type of box your using and like you said numbers do not lie. Use the #s to match your application.

Your mic is not good on some of these
