Miniature "subwoofer" help

Hey guys, been looking for a small 2"/50mm (cant be bigger) driver for a headphones experiment project...
It will work exclusively at 150hz and down,
I plan to force the driver to have a good bass response by lowpassing it very low if needed.

My main problem is weight and been trying to find a good driver that wont go over 50gr, have lower than 100hz res. point and that doesn't look like a scam :)

Im trying to avoid the classic headphones driver design for this task.
Any help would be great
Thanks

Inductor, Thanks but i cant use any of these sadly.

Hi, can you explain a bit more what your plans are? Low frequency response isn't usually an issue with headphones.
the response itself isnt the real problem, it will probably be even easier to shape it to what i have in mind,
but from looking around and hearing various headphones only the very few headphones had a bass that truly "did it" for me, and i cant obtain these drivers unless i buy the headphones itself, and these headphones are really expensive...
so I`m curious about how full range\woofer at the same size might behave at low frequency`s in headphones form.

...just trying to find something else that might have potential

from what i heard, somewhere around a flat response down to 30hz or 5DB+ at 30hz,
my goal is 5DB+~ at 20hz with open back design.
Try the B&W then.
Call them and ask if they deliver "the goods"!
They say their "Frequency range (is) 10Hz – 20kHz" who knows about +5dB?
 
There's something wrong in the analysis: if/when a membrane works in isolation directly coupled to another membrane, the eardrum, you just need a velocity transducer, so even a ribbon tweeter such as a B&G Neo 3 would work.
Talking about Fs and the possibility of reproducing lower tones is just absurd- for someone knowing the matter :cool:

I absolutely agree but coupling effect is never perfect when it comes to full size headphones, and the earpads i plan to use will are very big, so correct me if im wrong but i still think the res. point still got a role in this matter, maybe not as crucial as completely free air design situation but still...

How about buying a used pair of the better more expensive headphones.
And then use a EQ to boost the base or cut the highs.

Sounds like you need to do some research on one of the other headphone specialist forms like Headfi. When you’re talking about headphones you want to go to a place where they were headphone audiofile geeks.

That’s how I got my Seenheiser 800 HD‘s that I got That were $2300 new I got them used for $700. But the 800HD are the last headphone on earth you want if you like Loud booming base.
