smal subwoofer 3


Hi,

I am looking for a small (~3 inches diameter) subwoofer that can provide frequencies into the 50-60Hz range, possibly lower. It doesn't need to be extremely loud. This is for a research application, so I can pay for a scientific grade or THX rated system.

Any suggestions?

Thanks very much!

Is 3" correct? Does not seem to me that you can move enough air w a 3" driver to affect low frequencies. Perhaps if you have a dozen in the same box?
I never heard of a subwoofer with a woofer smaller than 8 inches.
Maybe for desk top systems that come with a subwoofer.
