you should have every customer send you a demo video of every box so we can see the final look /setup & demo. empty boxes are great but boxes with subs in them performing to show the audience what we all have been trying to imagen. great boxes great work quality and aesthetics!

Bro ! Put a battery in that smoke alarm . Those chirps won't let you sleep right at night 😴

Always great info. School in session, listen up!

Great explanation of port area. Have you designed any passive radiator boxes and/or discussed the pros/cons of passive radiators?

Love these vids!!

'Nothin but game!! I will support you till I die!!'

Great video

Can't wait for my box from you.

great explanation....ty

Good info 👨🏻‍🏫👨🏻‍💻👨🏻‍🎓

But how do know if you have enough Port area and volume is there a rule of thumb like a recommendated value for ratio of cone area to port area and one for port area to box volume I have a single 15" (1kw)in a 120L net (5,65cft) Box that has two 11,7cm (4,6") aeroports but I think the ports are a bit small considering the box size but if i made the ports bigger I think the sub would unload faster (with the current setup it only unloads below tuning when turning it 3/4 up) Is my box to big or are the ports to small

I’m almost certain that the box I have for my subs is way too big looking at that dual 12’s enclosure. I’ll be in contact with you soon though.

I like all of the videos from you which I have watched so far. I got a couple of questions 1-What is better - tune port to higher frequency or to a lower one than the fs? 2-if able to tune below the fs, how much lower, 5,10 or 15hz lower than fs? Keep up the amazing box building! Thanks.

Subscribed immediately

Once I save enough money I would love to have you build me a enclosure for my skar sdr15s

I got a sundown 3000 d to power a 8 inch truck box do i need 4 regular subs or 4 4 kicker l7 s or just two kicker l7 box to get maximum performance from one of your boxes and that amp

How do you have experience with different size ports cuz I usually do 11.5 to 12 per foot on the port but you're doing 16 I'm not chasing numbers I wanted to have a good bandwidth for daily still be loud tnx what do you recommend I got one sundown zv3 18 they also recommend for net on their web page with 64 square inches of Port area but four seems pretty small I wanted to do six I'm putting 3K to it

Hey man what is the mathematical equation for port tuning, i.e., HZ? Just a few months ago i did the math on a enclosure but all i seem to find now is a bunch of stuff i dont understand. My math verified what the previous owner stated so it much have been correct but im at a loss.

Great video as always MB. I'm curious about your thoughts and experiences with passive radiators, if any. Much respect.

How much do you boxes cost?

Great video you should teach car audio classes 101 😂

I had 3 MMat dreadnought 12s in a 4th and now I got 1 pioneer premier spl 15 in a slot port killing the 3 12s

@mbenclosures hey man love your stuff just wana learn how to build my own boxes i deff wana try to make it as light as i can got confused on which is the lightest in your other video i believe u said it was between the vaneer birch and the maple? but just wana have something that can slap most, trying to figure port length is killing me could i get away with a 3 cube box with 48 inches of port for two ct sounds meso 12s, is 48 not enough sound i do say 54? both tuned say 33hz or mayb as high as 35 i wana try to keep the box as light and small as possible (i know bad thing if i wana hit hard with 2 12s) going in a genesis g80 sport

What is the dimensions of the 2 12in box

88 ford mustang convertible can a box be made to fit by you the sub is a 12inch ds18 exl xxb

I have 4 15s skar vxfs & the builder made the port 6x21.. 126. Skar specs is 47.25 each sub.. so total of 189.

Your boxes look top notch. But I like the sound of a sealed box.

Do you ship any builds

What’s happening I’m excited knowledge and box day

What port area should I use for 2 resillent sounds platinum 18s in 12-14 cu ft box tuned to 33hz? I got 16 cuin in my 11cuft box but I'm stuck @150.4 @39 hz. I'm chasing numbers right now any help or design is appreciated. Thanks nice vids man 😎💪🏽💯

Correct

would making a port say.....going from 3 inches at the start to 4 inches incrementally to the end make any sense at all?

Got two Toro fierce 8 combo with the mr3 amp going on a squarebody suburban. What design is recommended? Ported or sealed. Music preferences: old school rock, country and old school hip hop.

Put a damn battery in alarm, c'mon man

I need a custom box built 430 Hertz pushing two skar 12

Do you do sealed boxes

That's what my 13w7ae needs.. lee stereo in visalia made me a box that only goes down 42hz.. smh ..

Anyone here has owned a pair of ampere audio 2.5 aa 8" subwoofers and have hit lows with a correctly tuned box?

Please help!!!!! I had a box designed by CAR AUDIO FABRICATION.... I built the box sounds good, but what DB should two 10 inch p3s be? I have a rockford fosgate r2 1200.1 watt amp running these two at 1 ohm final... I just feel like they should be a little louder then what they are... I did buy a meter and the meter was saying 109 Db... is that about right or should it be louder? Just wanted to ask the king in car audio... thanks buddy I appreciate it..

Honest option needed. One L5 12 in 2feet sealed or 2 L5 12’s in one foot sealed each. Running of same amount of power.

Great info as always. I have a L7 15 kicker..im making an enclosure @ 5.5 cubes... Port area 82.5....16.5 x 5 tuned @ 33...using the kicker amp 1200.1 with the sub at 2 ohms. Would appreciate some feedback from the BOX MASTER.

Any interest in doing a design for me

🤟🏻

What's the best box volume and port area for a Skar VXF 15 if it's tuned to 28hz?

It's that time............. to change your smoke alarm battery. It's sooooo loud over my phone speaker I thought my smoke alarm battery was bad. Also, your voice is low with some videos on my phone. Maybe need a wireless microphone so we can hear you loud and clear and get your words through our thick heads. I like your vids though. I've been in car audio on and off since the 80s. I have built boxes for people in the past. Now just build them for me.......

That first box comes out to 19.2 sq,ft per cu,ft. If that box 2.5 sq.ft

14.3 per on the 5.4 box if actually 5.4 cubes no? 77.62 ÷ 5.4 no? 15.5 with sub displacement no? Go bigger

Do you offer box designs if I wanna build my own?

The rule of 16 is bogus. You don't just take a box and slap a rule based on it's size. The driver is the determining factor. A Kicker Comp doesn't need near the same port atea as a RF Power series woofer of the same size. The excursion of the driver is the determining factor. The driver determines everything. Size of the box, needed port area and so on. When cookie cutter math is used, you end up disappointed in the size and or performance of the system. It is easily modeled in programs like Bassbox Pro. Also, building giant boxes makes it louder argument is also false. It makes it's peaks higher while diminishing overall performance over the subsonic spectrum. That's why you need to know what you are replicating first, then model driver and enclosure combinations to meet those needs. The next time you are surprised that a song that didn't seem to beat for you slams in another's system, you will find you are the victim of peaky enclosure design. That is why people who knock JL don't win SQ awards. If you like just being loud, go for whatever works. Math is your friend in either way and the stupid cookie cutter principal is still the wrong way to approach your build.

If you could build me a ported box for my two P3 12 inch I will be willing to show everyone and also make a review video on it I go to a lot of competitions also and i know i would win if you made the box i watch a lot of your video you know your stuff.

It comes out to 13.8 inches per cube

Change the battery in your damn smoke alarm. That shit is annoying. LoL

Smoke alarm 😂

That is 16.8 inches per cube

Why do 99% of all box builders use the 16” per cube rule?

2x15 7cu ft 16sq in per cu 2x 12 5.7cu ft 13.6 sq in per cu 1x12 high output 2,5 u ft 19.2 sq in per cu Probably all tuned 2 33Hz

I need this guy number ASAP

Any good programs out?

I'd hate to be stuck behind this guy at the Walmart exchange counter

You need a microphone 🎙️ it’s hard to hear you🙃

cone area its the king but net volume its the enemy :)

Would you be able to make me a custom box and ship to me

I can fit more 3 8' subs in that 2.7qft box with the same tuning and have more cone area then your 1 12 . Cone is not always king. 3 8' =21.75' of cone area your 12 is 11.25 ...

*beep* 😂😂😂😂

Smoke detector needs abattry 🙃

too much talking and NOOO SOUND

You too talk
