I would look at the 500/1. 250/1 IMO is lacking the power to properly get the most from a 12W6. I wouldn't even run it on a 10W6. What this causes is distortion at higher volume levels and eventually you could damage the driver. There are two schools of theory on whether distortion actually destroys a driver or not. I will not get into this discussion to long. Rule of thumb under power is just as bad as over powering a driver.
Absolutely. You won't be able to wring every last tenth of a dB out of it, but 250-300w is more than enough to get a 12w6 sounding very nice.

School 1) The correct and most logical one - according to the laws of electricity and physics
School 2) The wrong one - passed on from one ignorant self-proclaimed expert to another.
It's really very simple -- power kills speakers - not distortion (watch out for weak radio stations!! //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif )
If the same idiot that set the gain on the 250/1 (to cause this distortion you speak of - more specifically - clipping) set the gain in a similar fashion on the 500/1 the odds of damaging the sub would be much greater with the 500/1.
