Guys, I believe I have achieved solid balance with front comps, rear CDT 6x9 comps for rear fill and a maxed out sub and amp pairing with my JL 1000/1 dialed in at 54.7V. I have been pushing the volume into a close range of 3/4 full volume. I don't believe the amp is clipping, set to maxed unclipped volts and the sub seems to take the volume without any excessive distortion.
I guess you could say I'm looking to push this sub hard while maintaining soung quality intregrity and not jeopordize the mechanicals of this peaker.
What do you JL guys think about the 12W7s abbility to punp loud, consistant and sometimes brutal bass heavy material?
I woul be so BLUE to fry my sub.
Thanks
Demetrios

for the price they want for that sub it better be able to handle 480v ac current. but according to this link the ideal power for this sub is around the 750w range...dangerzone being close to 1000w...750w to any sub that can handle it usually is enough to pound the ground given the right enclosure .

1000 watts RMS is pretty much it or until the sub begins to hit maximum excursion. (X-max) When the cone travel reaches X-max, it cannot deliver any more SPL.
Also, there's the aspect of Thermal Compression to consider too. Once the sub coil reached a defined temperature, power output will also drop as coil resistance goes up notably at Tc. I think you may be close to Tc at 1000 RMS for more than a few minutes of high SPL listening too.
