An experimental micro suboofer design I made awhile back, the goal was to make it as small as possible and still be able to dig deep. Maximum output is definitely limited, but it is perfect for listening to music without disturbing neighbors... too much.
There is noticeable output down to 30Hz, but the port gets a bit noisy. Toss in a 4th order highpass filter at 40 hz and all that is left is smooth deep bass. Not bad for being less than 4L. Eventually I'll make some small fullrange speakers to go with it.
I really need to get a nice mic so that I can do some proper RTA.
