[QUOTE="Boominburban, post: 8600257, member: 664509"] Frank said that he hasn't had the time to get a 1250 series sub fully broken in, to pull accurate T/S parameters off of. He will never recommend more than rated power on any of his subs. But I can tell you that the 1250 is a tight gap motor. The former is on the thin side. It will take 2k CLEAN signal power, and be ok. But if you start sending a clipped signal to them, they will get hot quick. I spent over 6 hrs demoing last Saturday, near 2k on each sub, with no issues. There are a few guys that can make drop ins for them in different coil configs. But do to former/coil size, you can't ever really pour serious power to them. You are limited to around 2-2.5k. Remember, this is only a second step up the line, 1250 rms sub. If you really want to pour serious power to a sub, you need to step up to at least the 1800 series, or one of the neo subs ....
