Ported vs Sealed Subwoofer Box w/ Adjustable Port Tuning & CLEAN Car Audio Install + LOUD BASS!! 

Thanks!

@@E4EonEbay i take it those are the punches that ppl always say the old punch subs hit hard

Fucking right... blasting old school earthquake amp and Rockford fosgate subs. Gets it done..

I have 2 12 Rockford fosgates punch xlc's are they much different then thos

I also love this system, I definitely had alot of similar equipment. My subs were the earlier models i had the punch pro series 12s with 2 punch 150 hd amps and a punch 45 hd on 4 Altec Lansing 6x9s with a Sony deck and Sony xe- 744 passive equalizer

Thanks man!

Whatever

Mill Wurray Hit a 146.5 today with this "SHIT" bro... not to shabby for equipment nearly 20 years old on stock electrical

+Mill Wurray, I have no shame in competing in Rookie Division, and saying my equipment is shit because it is old is like saying a classic car is shit because it is old. This equipment was hand crafted in the USA unlike the majority of stuff on the market today. WTF is your deal anyways man? You hating because you ain't loud?

Steve Young just ignore him man. He's just talking shit like every other troll on the Internet. You have a sweet set up that fulfills your audio needs and that's all that matters.

Wait until you see my box that's really cool

Exo, i need a badass 10" sub and speakers / amp / everything for a new 2017 tacoma double cab. tacotunes.com/shop/toyota-tacoma-audio-products/double-cab-audio-products/2005-tacoma-subwoofer-options/toyota-tacoma-double-cab-subwoofer-box-image-dynamics-subwoofer/#jp-carousel-6574 ^^ thats the box that fits behind the rear seat. msg me the setup you would recommend please. Im ready to buy.

EXOcontralto I have a 1979 ford f150 single cab, still under construction but have two rockford fosgate p1 10 inch subs and rf 500 watt amp "dynoed at 623 watt rms" and two rf speakers with mid and high. surprisingly I got it up to 143dB. I think my next upgrade should reach over 160 dB easily with only 2400 watts

What is the first song tht was played, artist and song title? I need tht song banging in my trunks thru my subs ASAP

Keep in mind that dB's are a logarithmic scale. You need an order of magnatude more power to get that loud.

Happy to have you here, Wayne! Thanks for sharing the memory with us :)

Thanks man, I was a teenager in the 90's and this is the stuff I wanted but couldn't really afford back then... Now I can :)

Right there with ya. I have a set of old school cerwin vegas but im afraid to run em so they sit on a shelf so I can look at them. scontent-atl3-1.xx.fbcdn.net/v/t1.0-9/261991_701529018779_523937_n.jpg?oh=a7b67fc1438c492469c14d93b618f43b&oe=58874A43

God I want em

I was old school mini trucker myself. 4 Orion xtr 15's on 2 250 hcca's with a denon deck and changer in a Nissan hardbody. Good times

thanks man, it's a work in progress, I went from a 137.3 sealed, to 144.3 ported with the addition of the second 800a2, and my latest run was a 145.3 after readjusting my gains with a dd1.

Wouldn't really call it budget tbh. Maybe the head unit but all of this stuff is getting quite rare. Maybe the PVC and box really but I couldn't see the 6×9's and subs being cheap including the amps

Hw much is the set up plz mate

The rockford fosgate equipment is not cheap.

Yes I do :), especially anything oldschool!

Finally made a video documenting my journey as a noob beginner to 2017 NADBL Rookie Champion & NADBL Rookie of The Year! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DIz73wfZXeI.html

Thanks man!

I have the 12 version of them :p

FSXgta the first sub I ever owned was a 12" punch. I loved it. But, believe it or not, my (4)12" type r's get down. They are very underrated

Alpine makes some solid gear!

Steve Young this is way off track, but how many times you hear something about the old 49ers QB? I could only imagine. I used to work with a,guy names Jeff Backus and Matthew Stafford. It was ridiculous how many ppl would bring it up to them

Hey, it works!!!

Actually 4” slip caps on 4” pipe. Couldn’t make a better plug unless he used threaded and that makes changing tune quickly more of a pain.

The oldschool will always live in my heart

Thanks man! It took me a while to track down all of the pieces to the system, not like you can just run down to the local car audio store and grab stuff off the shelf anymore...

Thanks!

Thanks

How is it sloppy? just because its not covered in carpet?

yeah, you can't argue that progress has moved the hobby forward with vast improvements in efficiency, but I still like the oldschool. To me, driving a naturally asperated 500hp big block v8 just seems different than a turbo 4 with 500hp even though they are the same power, I don't care that the 4 is more efficient...

​@@E4EonEbay I would actually say they went backwards in efficiency for the speakers anyway.

My Stoner Mind you here???

Hey man love your bass head kitty's..lol

I didn't know my stoner mind watched exo contralto

ill bet you havent been sober in years

Ayyyyy My stoner

love the BMW in your profile, I had an E34 535i 5 speed, had this system in it too before I ported the box...

Oh yeah theyre surprisingly quiet inside if you dont install a teenage fartcan and good for sound quality installs too :) My car is an 1992 525i non-vanos 24valve model. I've tried many kinds of boxes in my e34 and I currently have a single 15" in around 90-100litre box with 44cm long 6inch diameter aeroport and that thing goes pretty low. Tuned to 30~ but makes plastic bags and other stuff wobble at 20-25hz like crazy :D Sounds pretty good compared to most bass installs I've heard so far.

id have to say the opposite is true from my perspective.. subs are wayyyyy better today then the 90s. considering spl like sundown and dd.. but amps, they have more power now, but class d power... no better amps made than the ppi art series and sounstream reference 1000sx....

LOL

hey steve what was that first song you played in this video ? i need that, Thanks Mate

Wtf it’s you and i made a video of my speaker playing bass I love you plz check it out!!!

What that music 3:18??

Mystique Sanda DJ

Thanks man, I hit 145.3 at my last show, best so far, 1db above the show in the vid. The Jimmy in the vid with the Contralto's is hitting around 149 to 150 on the meter at the shows. Lots more power than I'm running, as well as a much larger box too... I am still on stock electrical with single battery. I have to be careful, because I am dipping into the 10's for voltage. I think once I improve voltage I might gain a little, as these old RF amps are running unregulated power supplies, more voltage in, more power out...

Maybe get a 16v alt? Should make for a happy electrical system. Good luck :-D

Thanks man, were yours powers or standard DVC's?

Steve Young mine was Power series exactly like Urs. had 2 Crossfire VR2000R strapped pushing them. They can definitely take a lickin and keep on tickin

I love my black & grind RF amps, built like tanks!

Thanks man

That is a cool set up with the port tunes to bad someone has not made products for custom ports with tuning options like yours!

Lawrence818 right. I listen to different types of music and that set up would be perfect

Steve Young what would you recommend for a 2dr Tahoe, I like all music from reggae to rap to jazz... idk what setup to do, help?

Nothin' like a solid old school setup!

yeah, I agree, older cds also have higher dynamic range ad newer recordings have fallin victim to the loudness wars and suffer from over compression, Google loudness wars if you get a chance...

Steve Young I agree too, mp3 is compress and a lot of times people will add bass boosted to them and distort the track further

elice05 no they aren't lol .FLAC and .WAV are lossless file type which have better quality than CD

BlackRoseAnarchy very true, and if you know how to use audio softwares, you can always rebass songs... make the bass whatever you want it to be.

That sweet n sour sauce...any scheschwan

Oh hell yeah. The hx2 was an AWESOME driver!!!

spanKster so did i.

hometheaterhifi.com/volume_5_2/cmilleressayporting.html great read up on how ported enclosures operate with animations. Check it out if you get the chance.

Nah. The Excursion is not actually good. A seal enclosure can make more excursion, but will produce less bass overall. There have been tests showing that a Sealed enclosure will reach its limit much easier than a ported box. You can't run all you want to a sealed enclosure, you run into a barrier of SPL versing itself in a sealed enclosure.

It is all about efficiency, the ported box is more efficient at what ever the box is tuned to, above that it acts like a sealed box and below tuning the sub starts acting like it is playing in free air without an enclosure...there is some grey area just above and below tuning, but in general that's how it will operate (for example your sub will not be completely free air at something like 38 if you are tuned to 40). Sealed boxes have a much smoother roll off and a flatter response in general, they can get loud. Larger sealed boxes are more efficient in that they do not require as much power to drive the sub to its mechanical limits. People talk about putting a sub in a smaller sealed box increasing its power handling, not exactly true, the box simply becomes inefficient requiring more power to drive the sub to its mechanical limits, bad if you have a sub rated at 500 watts and it now takes 1000 watts to produce the same output because you will damage your sub from thermal overload.

It depends on the frequency, sealed has more protection below tuning, a ported box will unload the driver. Since he is tuned very low and playing tracks with no lower content, the ported is better for power handling.

For the time period that maybe true, but ours outta your mind when it comes to new school.

Rodney Watson The best Rockford Fosgate are Team Rockford and Power Hx2

Rodney Watson the audiophile Rockford Fosgate subs are my favorite.

I personally like all of the earlier single voice coil subs, ALL RF like the SPP Pro Series, PWR Powers & The RFR 1410's 12's or 15's. The had a higher sensitivity than the DVC's. I like the HX2 Powers but not near the sound quality. All great subs KEEP ROCKIN THE OLD SCHOOL!!!!! Love it

Lol?

I got 2 jl W0 12s. They both need new surrounds but that's a quick fix and only cost 30 bucks for both surrounds. I'm selling them both

guys like this are very special rare breeds... not only do they appreciate music but they appreciate the sound of music 😉 ah thank you

I appreciate your comment, I play a lot of albums with high dynamic range, Google loudness wars if you get a chance, most new recordings and even remastered stuff suffers from over compression. I listen to a broad range of music and I needed a system flexible enough to keep up. Also, these older subs are very musical and have a very low Fs of 20hz and a decent sensitivity as well, you don't get that with some of the newer subs, yeah newer subs handle more power and can move the earth, but they are geared more for spl systems.

Nice man, I love me some old school Rockford gear.

thanks man!

Had the 10in dvc in a bandpas 99-00 put a lot of paired 12s to shame. mtx 500w amp in a 92 sunbird

thanks man!

They were beasts, I ended up picking up a few more, have a total of 7 of them now

Tim Germany they sound as good as they look

Thanks for sharing, Adam!

Thanks man, I am running both the 6x9's and the pro60se's each on their own punch 800a2 at the moment and it sounds amazing

James less efficient sealed!

Steve Young mind blown thanks lol

Steve Young mind blown thanks lol

in this particular example if you watch when he caps the port to seal the box he forces air into the box, so the sealed box is actually slightly pressurized which is NOT how its speced to run. i think thats why you see such a pronounced excursion. id bet that if he released the pressure it wouldn't look nearly as crazy as that.

Hahahahahahahaha..... that's true....dude....

I would argue they're better, but they have their place!

Took me a while to find one!

I got two 12s rockford fosgate dvc punch

Steve Young I bet it did! I love the look of the old school Fosgate Trans Ana amps.

logan sayers nice to hear man...I'm a rockford fanatic I love all their stuff!!

Thanks man

Yes, the box is separate air space, 2.5cf per chamber after sub displacement. It allowed me to run two separate amps and mess around with sealing one side or the other to do a side by side sealed vs ported comparison without hurting the subs. The manufactured recommendation in the owners manual also states 2.5cf sealed or ported which is nice...

Thanks Steve, I realized that once I saw them move after you capped one side. Really cool I've being installing for going on 30 years, even doing it professionally and for a living and never thought or seen it. Great job!!

Snaus Pockets i totally agree, i have a old sealed 12in kicker comp VR, love the accuracy of it, the bass line sounds exactly how it should, with no particular tones being emphasized excessively. Just today i put in a big ported box with a single 10 in diamond competition sub , certain frequencies are at-least 3 times louder than the sealed 12 and its fuckin awesome, but songs that dont hit those frequencies are just kind of bland and not very impressive. I think the ported box is less predictable and almost more fun because you dont know what youre gunna get, where sealed is accurate and ultimately better musically

2 years later I am running a ported Skar evl 15" and the way it flexes my suv makes me feel like a teenager again. Tried to go back to the JL sealed for a bit and it sounds real clean but it has a limit and isn't big enough a lot of the time after getting used to the evl.

@@snauspockets9924 SQL subs in a ported box is a happy medium 👍

Thanks man, I finally broke 48 with the system now! Video is posted on my channel

Johnny is the guy with the contraltos, he is a local box builder here in NH and he does awesome work!

Yeah, when I built the box I did separate chambers so I could run one amp on each sub, also adds some bracing. I really loved the sound of the sealed box and was afraid it would sound drastically different if I went ported, but I wanted more output when on the meter, so instead of building a new box, I external ported the box I already had to maintain the 2.5cf internal volume and made some plugs to run it either way. It definitely has a different sound sealed, makes a huge difference on certain tracks.

+Steve Young so you don't add the external port internal volume to the overall box volume? I have always wondered about that

If you were to add the volume of the inside of the port, it would be added to both side, everything would still be equal. At the end of the day I guess you could argue that it would be a hair larger than 2.5 sealed with the added volume of the port when sealed, but it is such a very small amount it would still be well within the range provided in the manual of the subs, they are simply optimal at 2.5 sealed or ported.

Yeah most external aeroports don't account for much air volume it's not gonna make much a difference besides add resonance and tune the box itself (not the port) alittle bit lower.

And Steve young yeah I remember my old sealed box back when I listened to metal it sounded great and helped the subs keep up with the kick drum response. I'm running my 2 15s in a ported box now and they are alittle bit pokey haha

Thanks man! I recently hit my best score to date, 146.5dB, NADBL comp in Bradford, NH.... www.nadbl.org/index.php/results/2017-results

Congrats. Gaining 2 db is no small feat. You know your stuff as well with how seamless the system performs and creating the illusion of the rear speakers being presented as front stage. Im sure EXO asked you how that was accomplished. As a matter of fact id like to know myself. Maybe you could do a video on it when you have time if your willing and teach us all.

Sick man! Do you have a system yourself?

EXOcontralto not a crazy as I did back in the 90’s now just two 12 ‘s 4 6x9’s on a 4 channel 400 watt . Sounds fair .

thanks man, it might not be pretty, but it hits a respectable 145+ at the moment and it sounds pretty clean l, so I'm happy with it. I am hitting numbers better than some of my friends who have newer equipment...

I still have a working punch 45. It was a beast in it's time.

thanks man! I love the old school!!!

Thanks man!

Steve Young what song and artist is rapping at 3:25-4:50... I need tht song bro

Gudda Gudda- Gettin' To The Money

Got even louder later on during the season as well!

topped out at a 48 with that box and subs on two power 1100a2 amps

George it’s gudda gudda “gettin to the money”

Good ole Steve, definitely has come a long way!

Thanks!

These are the only subs I've been able to get 2nd hand and off to my cousin for the life of me he just layed those heavy mfka to rest

Thanks man!

Steve Young No problem bro keep it up! That's the best old school set up that actually gets loud and clean! Also being able to change from ported to sealed. Props to u

Just hit my best score today! 146.5dB I am pretty damn happy with it...

Steve Young nice!! Do u plan on staying with old school set ups?

it is a pretty different setup, everyone kind of looks at it funny at first...

That's why my friends call me "old school"...
