I have this beautiful/tiny creative stereo system and i noticed the unit (subwoofer?) does this awesome vibration movement when i play music with some bass to it. I want to photograph this phenomenon but haven't been really successful with it using just long exposure (it looks like a muddy blurr - i m looking for something a bit more pronounced).

Anyone here any any experience with this type of shooting? My next step might be to try to stack a bunch of shots together to see if that looks interesting but i m currently still experimenting/failing.

Try making use of a flash with the long exposure. The flash will freeze the speaker in place, with good detail (assuming you use high speed sync) and the long exposure will get the movement.

Well, the subwoofer is producing frequencies from about 20Hz to 100Hz, so a half-cycle will take between 1/40 and 1/200s. Try capturing one half-cycle, by experimenting with exposures in that range. You may need a few shots get one where the timing is right.
An alternative is to use a somewhat faster speed, just retain a little motion, then get a shots near both limits of motion and combine them.

Or, a multi-strobe effect.

..

a further alternative would be to put a light on it (LED?) and FAST pan while exposing, giving you a visual representation of vibration over time.

This ad has always been the quintessential stereo system ad, I dunno if it says "vibrations", but it's a classic.

Is it Live or is it Memorex

I would try something with a fluid sitting in a container ON the sub, and play various low tones until you create a nice standing wave in the fluid. and photograph that.

Here you have a varied collection of demonstrations of standing waves. Perhaps not quite what you are looking for since the speaker is not really the focal point.

Personally the more visually appealing are Chladni patterns and Rubens' tube
