Gold Member Username: James1115Ct Post Number: 6495 Registered: Dec-04 | dont do it man! A common misconception with regard to dual voice coil speakers is the assumption that nothing changes if you power only one of the voice coils. With only one coil hooked up, a dual voice coil speaker will suffer a loss in reference efficiency of about 3dB (only half the coil windings are being energized) as well as a significant shift in its Thiele/Small parameters. This renders any enclosure calculations inaccurate unless you remeasure the speakers parameters with only one coil hooked up. Failure to account for the different parameters of a dual voice coil speaker with only one coil powered can result in very poor performance. |

Gold Member Username: James1115Ct Post Number: 6496 Registered: Dec-04 | it wont damage the amp, and inless you reconfigure the enclosure and thiel small peramiters it wont sound up to par. You will lose 3 db's on each sub, you will not be any louder running 2 then you would running one propperly. |

Silver Member Username: CtxPost Number: 166 Registered: Jun-04 | so would be better to just run one 15 in a small sealed enclosure and dump a ton of power to it? |

Bronze Member Username: LikeapumaWashington/Utah Post Number: 15 Registered: Aug-06 | Yeah, it all depends on the sub. My Farenheit subs are made so you can run either both coils or only one, and there will be no difference. And the Xsite rep told me that their high excursion subs are the same way. And I'm pretty positive that the Massive CW says on their site that those coils are made so you can run them independently. Just check with your sub manufacturer. -C |
