[QUOTE="Remotia, post: 2226397, member: 568127"] The coils are actually 1.4ohms each so the final load would be 5.6 ohms and be closer to 6-7 ohm nominal impedance. 300 watts is not that great for that driver, but its actually not that bad but the TC-3000 would not be my first choice for that amp. Despite its huge appearance its surprisingly pretty sensitive, especially the +CP version. the 12" can get up to ~87.5dB... really not a bad number for the kind of excursion it can do. The larger drivers actually have higher sensitivity than the smaller ones, contrary to believe, larger speakers would theoretically be more suitable for smaller amps, however there reaches a point where there is so much BL product that you need an amplifier that can generate a huge Voltage (not necessarily large power levels or watts) Many amp's can't actually do this, but those that can are the ideal amplifiers for these massive motors because of the huge back EMF which can neutralize the voltage.
