any body tried a isoberic (clamshell type) subwoofer cabinet in a car ?

[bottomfeeder]

I have one at home using 2 mtx 5500 12" subs .

The speakers cone's face each other and one speaker is wired out of phase .

Bottom line the speaker is fooled and thinks the cabinet is twice the size , so I am thinking a car would be the best place .

Just figure the smallest sealed box for that driver and cut it in 1/2 mount both drivers facing each other and you are set .

I ran the drivers perimeters in Winisd .

It goes real good .

just remember that it also halves each speakers power handling as well. not to mention the output. it is good for saving space, but very inefficient.

no, this isn't the 1990's

A clamshell is different than isobaric. Isobaric does reduce required enclosure size by half, by in essence doubling motor force (BL). But you now have two speakers, costing twice as much as one, requiring twice as big of an amplifier and power supply system as a single sub, but has the output intensity of just one of the speakers.

As implied above, the isobaric design became famous in the 90's due to the large enclosure requirement for subs back then. Those subs were efficient because watts were expensive back then, but this also meant much larger boxes than today's subs. There is an improvement in SQ with an isobaric design versus only one of the speakers, but this difference is so small as to be considered inaudible. For most situations today, the isobaric design surpasses the point of diminishing returns on investment. I have no idea why you incorporated an isobaric design into your home stereo, considering space is not a problem in that context.

People argue that isobaric(or push-n-pull) designs have less distortion and non-linearity because essentially it is two woofers operating out-of-phase, and anything that isn't included in the program material gets canceled out. The design like said above is out out of style with today's high-powered amps and long-excursion subs in car audio, but it may have decent benefits in the home audio world where people are ultra critical about sound quality.

Now you know where the name "Solo-Baric" came from.

back when a 15 wanted 12 cubes ported, they worked good.

I still own a quad 6x9 bandpass made by Polk in the 1990's. Quite the novelty. I have absolutely no use for it.

Correct. The original solobaric is imo one of the fathers of most modern car audio subwoofers, in that it pioneered the idea of a low efficiency, small enclosure subwoofer. Its release, and subsequent popularity, ushered out the era of the large enclosure high efficiency subwoofers I described earlier. So its somewhat ironic it carried the notion of 'isobaric performance' over into the new era via its name.

i could see the design being used possibly for small subs in a bar style enclosure to fit under a TV, or literally inside of the existing televisions speaker compartment. even then, they make 3 inch subs or even 2 inch ones for those types of applications.

So what are you brainiac bassheads saying about this and todays moofers? I was thinking about this option as well, but I havet seen it praticed since the 90's when shit was banging...

I was wanting to try this out, but with my folded tline enclosure.

Back in the day subs had weak motors and suspensions, so they needed massive boxes to get good sound. Todays subs work in crazy small boxes compared to subs of way back when.

But that being said, no. Im sure that not a single person has ever tried 2 speakers isobaric in a car. Thinking that some person in the countless people who have owned subwoofers might have tried doing it is absolutely absurd.
