Luis Gutierrez main reason to invert would be the box being too small, tuned to high; which doesn't help much; or in my case you're slamming lows on over rms power and getting the sub warm. I invert it because ive took my box out in the summer and took it inside to pull my sub and the motor was hot inside the box with it not being inverted. Box has around 4 coats of fiberglass resin inside and out. Sealed very well. Have a half ohm of rise at 23hz. Clamped my audio legion 1600s wired at 1 ohm each amp and got over 1500 watts per amp. Very impressive for a 1600 watt amp. Right now I'm wired to 2 ohms per amp one heavy hitter 12 getting around 850 watts per coil when rated 1250rms. She takes the 23hz all day long though and the whole box jumps. Gotta get some bigger brackets to hold it down better.

Glad I got a demo in yours as well!! Hopefully I’ll see you at shows next year

Facts yes but some subs do not play well inverted ie bdc-4s do not like inversions

@@ParkerTheBasshead brother, I love your setup in every way, wish I lived closer because I would help you get louder. You sound deaden the doors and especially the rear hatch? And the way it performs you'll get better cooling with them inverted of course but if you can adjust the aero ports to tune lower you can get more out of it. Get it to peak right at 39 or 38hz and I think it will get alot louder. Those subs are built for lows if I remember correctly. Maybe even peak at 34hz, my high peak is around 40hz and I absolutely slam at 26hz hard enough to be heard in the building I work at 80 feet away from the maintenance guy inside. He couldn't believe it was 1 12. Just a heavy hitter 12 with one audio legion 1600 on each voice coil at 2 ohms. Does great for a single 12, tuned at 30hz around 2.7 cubes. Sub is of course inverted for cooling since unfortunately it has just a copper coil without the high temp coating. But I love it for the price point. I love it as much as my soundqubed hdc3.1 honestly. Very nice sub

Thank you!!

Thank you!!

If i win the sundown you guys ill giveaway my 2 skar evl 12s!

So would the hole need to be bigger then? And how much bigger?

That's why I don't believe in inverted subs. They were not meant to be mounted that way.

@@martinramirezmi5457 Some people invert some subs that sound bad inverted, on top of that have air leakage and on top of that complain they got not much output on the low lows. Can’t fix stupid.

what kind of jl was it . bro was jlw7?

@@bellaphone5719 No. The simple JL W0 15”

Sometimes subs motor/suspension/venting makes noise that becomes audible when inverted which makes it a little less worth it.

@@RobertJeffersonBased exactly why i dont do it my 2 skar evl subs are way noisy inverted

He got lower db in sound but lost a bit of gain in sound like he said why ? because that box looks like it was made for traditional mount not inverted and the volume changed because it got bigger with subs inverted the tuning changed not the port but puting back in traditional will give him the same db and volume in size air space made for traditional only difference is lower tuning /volume size & changed in db

Realmente si en parte si la caja es mas grande la eficiencia aumenta, el subwoofer se mueve con mas facilidad pero si se sale del Xmax existen limites mecánicos que no permiten que se aproveche la potencia que reciben. Se puede ver en el video que los 2 amplificadores Taramps 8k estan en cliping pero no es por que el amplificador llegue a su limite operacional sino que el subwoofer llega a los limites mecánicos (subwoofer clipped-off) y se da el "Xmech" el amplificador intenta mover el subwoofer con toda su potencia pero no puede por el limite mecánico del subwoofer y pueda ser que por eso se dañan los fusibles.

Your reply is literally perfect

Sorry forgot to tag you. Awesome reply. I'd try to tune lower since he has aero ports. Going to try to talk to him about it

Don't know why it won't let me tag you P-Bass but you said basically what I would have said. Most people just tune with a 40hz tone not realizing that if they are tuned at 32hz they more than likely are going to clip when playing 25hz because the amp is going to produce more power below tuning than above. Showed the video from my friends skar skv2 3500 doing 66 volts clean at 24hz when tuned at 28hz and when playing a 40hz tone it dropped to a little over 33 volts meaning if you tune with a 40hz tone you'll start to clip when playing below box tuning. My heavy hitter 12 is inverted mainly for cooling but would probably be louder in the box because the box is a little too big at 2.75 cubes. Might add a little bit of wood around the inside of the baffle when I put the wood tnuts in to help take up a little more space. Adde a thin piece of wood to the inside side wall to take up some space and it definitely helped. But inverting mainly helps if the box is a prefab or too small or you're running alot of power with low rise and need to keep the motor cool. She gets warm but never hot. Love the black brick heavy hitter 12

@@michaelmosher7902 good plans...btw, when measuring, especially in sedans like mine if you open the rear door (on the left side if the meter is on the right side of the front glass), then this can being the sub's peak near to the tuning frequency...for example: I have a single 6.5 in a relatively simple approx 0.8 cuft net volume box tuned to 22 Hz, when I close everything, it peaks at 52 Hz - my best score is 127.1, with opened front door 128.1 at 51 Hz, with opened back door 127.3 at 23 Hz...maybe I will upload a vid of it this week...also other subs what I tried in my car, they were loud exactly at lower 50ish frequencies, so maybe 52 Hz is the resonant frequency of my car's interior, and I simulated that if I extend the box to a parallel 6th order - high tuned chamber will have the same exact outer dimensions and made of the same material like the box now, it needs to be tuned to 57 Hz to gain the most around 50-53 Hz, exactly +10 or +12 dB.

Yep, I've done the math and the average box goes down in tuning about 1-2 hz. Barely noticeable in real world listening.

Yep! Exactly what mine did

@nate0 I doubt you can tell a difference. That's like saying your system is not as loud when u have 3 passengers vs just you inside by yourself.

@nate0 if you do that they will sound the best, because you will get the best stroke going in and out

@nate0 yeah for sure, even if its not an spl build it’ll still sound a lot cleaner, punchier, and maybe even louder
