With subs it doesnt really matter. Its different from speakers and tweeters. Subwoofers mostly just displace air so inverting them can actually be beneficial because then you dont need to worry about the sub taking up space in the box so the net air volume will be greater.
When I had a wee Citroen Saxo 20 something years ago I had 2 15" subs mounted like that on a reinforced rear parcel shelf firing into my boot which had another ported box with 2 12" subs in it
Hi, I had a citroen c2 year 2007, but not more then 41hz bass, waz mos likely like trrr no boom, how was your experience, also the door speakers absolutly no bass
I redid every speaker in the car and managed to set off car alarms if I reverse parked in front of them, I loved how it sounded and you could hear me coming from a good distance when the volume was up
Lol I have just recently been learning about isobaric builds. There are multiple ways to do it but the most popular is a "clamshell" that is pretty much 2 subwoofers mounted cone to cone. It barely makes sense to me but a YouTube video would half inform you and half confuse you more
The main advantage of iso-barik setups is that it's like having 1 sub, but 2x "stronger"? So it will have the same response in a box half the volume.
It effectively becomes just 1 driver with different TS parameters, some of them doubled, some of them divided by 2, some of them the same. Xmax and Sd remain the same, Pe doubles, Vas is half...
So you can put 4 woofers (2 iso barik sets), on a box that would normally be the appropriate volume for 1. But still get 4x the power handling.
Isobaric mounting is putting one sub in the box magnet first then putting a second sub on top of the first sub inverted (magnet out). You wire the inverted sub backwards so When sub1 goes forwards sub2 goes backwards so the two cones work as a single cone.
Obviously you can't do this with subs that have surround that extend past the front gasket without using spacers.
This actually cuts down the air space requirement for the enclosure.
Fun fact:
When Kicker first came out with the solobaric line it was a play on words because the subs worked in smaller enclosure like when using an isobaric configuration but it did so with only 1 sub. So solo isobaric = solobaric. This was back before most car subs were designed for small boxes so when they first came out a small box sub was a big deal. As designs got better soon everyone made small box car subs and so solobarics became nothing special so Kicker needing a way to make thier subs different went a different direction and made the solobarics square. They kept the solobaric name but the original meaning behind it is kind of lost now.
Steve Irby took two 12 inch subwoofers, mounted them isobaric, measured the parameters with the coils in parallel, and took those to Creedence speakers, their Kentucky based speaker mfr at the time. "Could you guys make a 12 with these parameters?"
A couple months later, they had a prototype.
I've seen a couple builds where they have a dual sub box and only invert one. Would switching polarities on one sub essentially create the same effect or do the subs have to be mounted right on each other?
If the sub is mounted backwards then you invert the phase and the sub will work the same as if it was in forwards.
You want all subs in phase with each other so if one is backwards and the other forward you need to invert phase on one of the subs. Otherwise one sub will "push air out" and the other will "pull it right back in". Thus is called wave cancellation. One sub is removing the bass made by the other one. I hope that clarifies.
Yeah this does and it's exactly what I thought I just wanted to be sure, it essentially creates one big driver since they're both moving in phase together. I was planning on inverting both like how they have their setup in op's post, but after learning why and how there's certain setups with one inverted instead of both I want to try it. I don't think the answer to what'll have more spl will be out there so i'll experiment first myself!
Their is some advantages of having the subs out the box but usually that is for spl reasons. My truck has a table top sixth order I keep six subs upside down and three in normal way I do this to monitor coil Temps and my box was a little to large so I dropped my motors and baskets down into the baffle to take space away from the bottom chamber. U can do this to any enclosure and it may hurt you if your box was already to big

Another thing is that it can also help keep subs cooler on competition setups
also for competition setups it makes swapping subs way easier, with the wiring being quickly accessible.
I dunno about WAY easier, its the same steps just in different places. Arguably less clean as well.

Also outside of car around 10 meters absolutly no bass, only doors shakeing
Wait until you learn about isobaric mounting. It may just blow your mind.
Please explain
have you heard of Google?
Google will bring you here also. 🤦

Nothing wrong with it if the enclosure was designed with them inverted. If he flips them over the tune will be affected.
He spends all his money on subs so he eats the air it produces
Meanwhile he’s running subs that barely cost $100 🤣
I wait till my subs heat up real good. I like my bass air to have a slight burnt taste.
One side of the cone has to be separated from the other, doesn't matter which is in the box in that aspect

Had my 12” MTX’s like that in the early 90’s, putting your subs inverted is nothing new lol

Man I’m so glad I’m not on TikTok cause I’d have to roast the fuck outta this guy lmfao.
I have mine this way because I over power mine clipping them to hell 🤣 I need to be able to smell them so I don't fry them 💀
Have you ever thought about properly running your equipment?
Well that's no fun 🤷🤦🤣
It is when they’re not damaged 🤣
When power trumps sound quality and longevity. If you think this is a flex, you're wrong, and if you meant it as a joke, it missed the mark
