Thank you everyone for your responses.

I am aware of dual loaded subwoofers. I'm simply looking for a project to expand my knowledge of pd. You're post, as everyone else's, was none the less very informative.

I'll do a little more investigating into this idea; although, I will try to brainstorm another project to tackle with pd.

If anything I've learned more about latency issues.

OK, maybe calling it a "white paper" is going a little too far since it was written by a college senior. Here it is anyway: http://www.danmarx.org/audioinnovation/servosub.html.
OK, let's say I set up a Raspberry Pi to work in real-time. I'd have to use a language other than pd right?

My experience with pd is comprised of the Dr. Hernandez tutorials and some controlling of leds and servo motors. I am a beginner in search of experiments to better my understanding of pd.
I read, a couple nights ago, a white paper on subwoofer servo controllers, used to lower distortion and better the frequency response. Essentially, an accelerometer is attached to the woofer's cone, which measures the output. The signal is fed back in, at line level and out of phase, to the input of the subwoofer. The measured distortion is effectively canceled out.
I thought to myself that it would be simple to write an equivalent patch in pd to the necessary electronics. On the other hand, I remembered the latency issues with pd. Am I right to assume that pd isn't fast enough for this particular application?
Would overclocking the computer make any difference (I'd even be open to watercooling, just for that sake of experimentation)? What about building a kernel? I read that even with these adjustments latency can only go so low as 1.5 ms, which I believe is too slow.
