Default 2.5" Subwoofer??

I know sounds strange But I am in need of a 2.5" subwoofer thats not a typo. I have a speaker systemn that has a dual ported 2.5" subwoofer but it lacks anything even kind of deep. I know its tiny as can be and tiny woofers are not good at deep bass, I know my speakers very well, So I know finding a 2.5" subwoofer that can hit down to atleast 65hz is unlikely but I want one, it needs to be atleast 10 watts rms and hit at least down to 65hz please help me out. it has to be that size no other size will work.

65 Hz is more woofer territory. Getting a driver that small go that low probably means big & low efficiency & low max levels.

TB 2" (a stretch to go that low)
TB 3" (it should)

I did find a great speaker it is in this link
Audience's A3; new true full range loudspeaker. - Home Theater Forum - Home Theater Systems - HomeTheaterShack
But is is $170, the cutout diameter needs to be 2.5" I forgot to add that. It bugs me how I find a driver that meets what I need and it costs more than just completely upgrading my monitor. This is for a computer monitor that has a built in sub. But its current sub only hits down to 100hz.

then add a 4inch or 8inch or 15inch driver for the low frequency duty and stick it under your computer desk.

If you're going to stick a different 2,5" driver into the exact same enclosure, performance will most likely still be enclosure-dictated. Unless you change the tuning and/or increase the volume it might just be an increase in cost not deep bass.

Personally I think you would be better off looking at the TB 3" full range - decent xmax and power handling and also should be able to hit 65Hz depending on the enclosure.

Ahh OK... think about it folks... even Sony 50mm headphone drivers go real low just no SPL's when much farther than your ear

i have(unfortunately) researched and tested an abnormal amount of time on finding a small size subwoofer and came to the conclusion that a sealed 6"-8" cubed box is the smallest enclosure that will produce lower bass hz's, but will need more watts to drive it.

any horn will have to have a larger speaker or longer horn path to make sub bass. along my path of discovery i found that 4" bass speakers could reproduce, down to about 60-80hz, in a 6" wide horn configuration with the horn path around 4 meters long. using a coiled design the space was similar to some regular speaker enclosures, but with a lot smoother(less distortion)response and extremely more efficient.


ultimately the cheapest solution is to find something second hand that fits your need as raw materials alone would cost you more without adding your time.
