Back in the day I had a Chev z71 pickup with custom abs door panels for a pair of old school German mb quart 6.5 separates and custom kick panels i fiberglassed with 6" Atomic mid bass drivers and in the stock dash location I had these bad ass 4" and 1" tweeter pods mounted made by Advent but they were nice. I used Aria 25 watt per channel high current cheater amps for the mids and tweets and a Autotek Mean machine high current amp for the bass. All the amps were 1 ohm stable bridged and I had an active 3way xover for filtering. One amp did tweets, the other same model amp for mids and the Autotek for the bass. In competitions it was rated at 200 watt class total. My subs were 2 Atomic 1599s in a 6th order isobaric tuned at 30 and 60 hz respectively. That box hit so hard that it was hard to listen at its limit. It would hit 152 spl db with a comp microphone. It was a sound Q system, but it was good for most music. Best for rock.

Just a li'l correction: Though "iso" means "equal" in some cases, it means "constant" or "unchanging" in other cases. For example, in this case, the pressure of the air trapped between the faces of the two cones is (or should be) constant, unchanging.

running a sealed isobaric cuts your box volume in half and as you already explained the 2 subs working together don't have to work as hard but you left out equals ....better sound quality...Also deeper bass. Which you can really hear the difference in a small cabin vehicle like a pick up truck where space is limited. Win Win right. I highly recommend a pair of old school Kicker Solobarics due to their design (there's a reason why they're called Solobarics). Or just any heavily worn out pair of subs that still work before you throw them away. You'll be glad you didn't toss them out. Very very simple box . Half the sealed volume required for just one of the subs. Simple as that

there's something missing at this explanation. The main reason why someone will use a isobaric loading it's just to get out the same performance as a single woofer, but with a half a space of the enclosure. In fact, at the same volume of air with the same voltage applied to both speakers, supposing that both are exactly the same speaker, you will loss 3db, compared to a single woofer at this same enclosure. But when you cut the volume of the chamber in half, you will get the same performance as a single woofer. The main reason why someone uses isobaric loading is to get a more compact arrangement Souce: Hexibase
@vikassm3 жыл бұрын
Your explanation is correct. Isobaric configuration produces the most dB per cubic foot of enclosure volume, at the expense of higher power required. Not everyone can/will fit huge subwoofer enclosures, for practicality or simply for aesthetic reasons. Each enclosure has its own set of positives and tradeoffs. Ported enclosures produce the most DB/watt over a narrow frequency range, at the expense of enclosure volume. Sealed enclosures produce the most DB/Watt over a wider frequency range in a smaller (than ported) enclosure, at the expense of more power. Horns produce the most db/watt, at the expense of being the largest enclosures. Open baffle dipoles produce the most accurate/Least colored bass at the expense of power & specific positioning requirements. And so on and so forth. Don't quote me though, I may have mixed up a couple of things there :) This channel is awesome, Hexibase is awesome too.

I think clam shell is the 3 db loss but if you have twice the cone area you stay the same or gain I know cone to magnet stays the same on spl db . If it don’t work out I’ll just make another the same and make them that way.

@@haroldhprittjr7007 - With all isobaric arrangements (no matter if cone to cone, cone to magnet or magnet to magnet) you do NOT get twice the cone area. It's exactly the same as one single driver, so displacement volume stays the same as well. It's really just Vas being halved when compared to a single driver. Things follow theory best with the tightest possible mechanical coupling (= smallest enclosed volume/mass of air) of the isobaric drivers which is achieved in cone to cone arrangement. Another advantage of the cone to cone (and magnet to magnet) arrangement is the potential reduction of 2nd order distortion. Most drivers show a slightly different behavior and outward and inward motion. This gets cancelled out in push pull configuration.

@kevincourneyea33466 жыл бұрын
The only thing an Isobaric configuration is good for is making any box half the size (except T-Lines). Two drivers in a Isobaric setup given twice the power you get the same SPL as 1 driver with half the power. You are doubling your BL but your woofer efficiency is halved. Double the BL=half the size of box for any given tune. The smaller box required a port twice the length to be tuned the same. You can make your ports smaller but air speed increases. What Isobaric enclosures do allow is double the boxes, so twice as much space for speakers. Or if you want a 15" in your trunk and it wont fit. But you will need twice the wattage for it to be as loud as 1 15" or be 3 db down. If you have 2 twelves you could have the output of 4 and fit all 8 12's with an Isobaric setup. But in general you can get 3 db more per cubic foot at the cost of 4x as many drivers and 4x the amp needed (otherwise if you have the space with the same amount of hardware you could have 6 db increase). Any Isobaric setup if taken apart and put in the larger boxed equally tuned counterpart will perform a full 6 db higher. Alas if there were any box that I would advise against this type of setup it would be anything where both sides of the subs have different tuning and are loaded. If you have designed your box for your amp and sub to reach your subs mechanical limits at max amp power (even if gain set) the cones will no behave well. I know it is done but beyond not having the space for 1 sub or the space for more subs it should be avoided. That little space in between will change pressures and substantially in the middle of 2 tuned chambers and a bunch of watts. The subs will not be doing as your math says they should do.

Running off a hyphonix or however you spell it amp. I believe it pushed around 2000 watts. 2 batteries optima red top 2 caps and stinger 200 amp alt. Anyway it recorded 155 or 156 range. Not bad for the mid 90's. Now kicker's first well second solobarics. Jensen the word basic. Had a TORNADO box specific to the kicker these were 2 10's running in a suburban with the biggest fosgate dsm I believe one to each sub anyway in the 90's. All I know was it was so loud it cracked the front window. Replaced it with a good window and brace and it cracked again. Then went in the lexan stuff. But anyway amazing for 2 10's. Isobaric loud as all get out.

Honestly I think you could have done a lot better explaining what isobaric is. The push pull refers to the drivers facing each other and one is wired up with reversed polarity. The reason for using isobaric is to double the power of the speakers but only have the footprint of one driver. Some people say it lowers the tuning of an enclosure as if it were double the size.

Isobaric configurations don't move more air, the pair of subs move the same amount of air as a single sub, but much easier and more efficient. This means that you can use a smaller enclosure because the air-spring formed by the enclosure and port can be tighter. You can also use a smaller amp because the efficiency is better due to the double motor structure. It was popular in the older days because SQ classes were limited by power output of amps. With this configuration you could get small enclosures for more control, yet have solid impact due to stronger motor output, and still use a small amp due to lowered efficiency.

The kicker (no pun) is that youll be looking at a sealed glowing center tube thats axtually double fluted, and shaped like two tornados with tails touching in the middle. Theres no additional performance benefit that Im aware of, but I got that double-tornado shape of aerospace-grade acrylic from work, where wed been testing a process for it, and ended up with something crazy once. Ill send you a link by next week after Ive got to a section in the assembly when Ive got the time to edit sonething together. I'll say this...just to use that one cool element, has brought into play some math I had to leave overnight to run on a Wind Tunnel supercomputer at NASA to be done by 8am the next morning. calculating air volumn within the middle sealed space against the effeciency of air movement between the cones (which are also a third and forth tornado shape that must be factored) was beyond me. Ill get away with the run time by filing a use-form around a study on aucustics or something, so thats the priority before posting a video about it.....as will making sure I dont blow something up...and not tape it. That said, that was the best explaination Ive heard ANYBODY ever give on isoberic bandpass enclosures. Or the principals behind it which are relevent in many different disciplines. Its so easy to drift to either towards the science, or not go into it enough. In 10 minutes you touched on every essential point, and Id imagine most people to leave being confident they can build one...and will have the skills. Thats hard to do, to have them absorb the knowlege, and to also speak on the same level as your listener without speaking "down". So, "Well Done" If my opinion has anything to say about it.

I like the fact about it is not one person believes you when you say 10s and they sound like a15 deep low bass un distorted the port is like 22sq inches about 24 -26 long . It moves a good amount of air with no chuffing ! The foot print it makes isn’t that bad it’s around 14x16x32 and the other part the bottom box sealed one is like 14x14x16 take that off the tube is only 16x13x21 but it sounds so much better with that on it

I'm going to do this with two 15" subs. One enclosure tuned to 32hz...the other tuned to 18hz. Hooked to a 3,000 watt amp for my sub in my home theater.

I have two Bose 6 inch drivers from two subs I took apart that was thinking of doing this too but I’m not sure of the box dimensions. Do you think it would work good
@BudgetBassHead3 жыл бұрын
sometimes you have to just go for it. Research other enclosures with 6 inch drivers and see what the specs are. Look at part stores with simular looking drivers and go from there. Good luck

That’s not an isobaric bass reflex. That’s an isobaric 6th order bandpass. An isobaric bass reflex (4th Order) would have no partition and the rear of driver 1 would have the motor outside the box. An isobaric bass reflex (4th order) is a standard bass reflex with an extra driver and the box is half the size of a standard bass reflex box.

Isobarics do not always have to have 1 of the subs wired out of phase thats only if they face each other now if they face the same direction you hook them up in phase as you usually would.

Title image shows "isobaric bassreflex" then you show a 6th order bandpass , with isobaric drivers. Then you start talking about people "don't understanding" something.

So if you take 2 drivers and use them both in a ported box and use them both in a Isobaric 6th order box, which would be louder?
@BudgetBassHead6 жыл бұрын
Saddendude in my opinion it is not about how loud and enclosure is, it's about efficiency. But regardless, a 6th order will always trump a traditional ported enclosure; in my opinion. For, I would rather have my enclosure peaking at two different frequencies opposed to peeking at only one frequency. So yeah, I would choose the isobaric setup; to answer your question.

U don't sound too sure about how to wire one sub out of phase, sounds like you were sayin both need to be out of phase as well, nope,just one, and you just wire the one speaker right,and the out of phase speaker needs to have the posi and neg reversed ,too easy, great for when you don't have alot of airspace to play with

Well let me be the first to tell you it works very well and you can get away with a small enclosure my friend put one in his 240Z he only had two eight inch subwoofer Rockford Fosgate and they hit so hard it was so unbelievable that that small box for 2/8 and it sounded like that he had it tuned for the midbass so insane 80 and above is it with authority man it sounded as loud as 2- 12 in a ported enclosure it was ridiculous the only drawback to it was if the Bass Below 80 Hertz it sounded as though the subs was coming apart.

Iso = 1/2 vas, less air movement (smaller box,) -3dB efficiency. Double mms, double rms,
