Sounds like you like Rythmik. Their Servo system seems interesting. The owner of Rythmik told me the REL's won't provide the kind of bass extension their subs can deliver. Another speaker manufacturer said the REL T/9i's will be lucky to play down to 35 Hz. I certain songs play a lower Hz levels, these will not be able to play those frequencies.
