Silver Member Username: SwisherMarianna, FL Post Number: 265 Registered: Apr-06 | damnit them ima have to wire it to 2 ohms cuz its a dual 1 |

Silver Member Username: Baseball1187Columbia, SC Post Number: 709 Registered: Dec-04 | yall are crazy... using one VC is fine with that being said... do not put the combined RMS of both coils on one. a lot of people use one voice coil and then do various other things to the second (leave it open, short it) to change the QTS of the sub. This was the idea behind the AA sub (the model slips my mind)... it was nothing new, just a little different spin on the idea |

Gold Member Username: IlluminatorUSA Post Number: 4494 Registered: Apr-05 | The above poster actually gave some insight as to why it should not be done. It changes the parameters of the enclosure you need to put it in, a.k.a. you probably will ruin it because the box has an extremely high chance of being too big or too small. |

Gold Member Username: James1115Ct Post Number: 6418 Registered: Dec-04 | 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: Basshead86Google is your Friend, FL Post Number: 4777 Registered: Aug-05 | i believe you could do something to the effect of changing the ohms on a Ava from 2 to 4 and it raised the efficieny of the driver....i dunno WTF i am trying to say.... |

Gold Member Username: James1115Ct Post Number: 6427 Registered: Dec-04 | on the atlas you could change the qts ofthe sub, but the second VC used was not te same as the first. Thats what make teh Atlas different then a normal dual VC sub |

Silver Member Username: SwisherMarianna, FL Post Number: 271 Registered: Apr-06 | its ok i wired it to 2 ohms and its gettin a healthy 1500rms |

Bronze Member Username: Matt_stuPost Number: 55 Registered: Jun-06 | hmm this thread made me wonder if i wired my arsenal wrong. i have the speaker wire hooked up to the right terminal and nothing hooked up to the left one. the sub is 2 ohms and the amp is putting out 750w at 2 ohms. is my sub hooked up right? |
|
Bronze Member Username: Matt_stuPost Number: 57 Registered: Jun-06 | im thinking should i have it hooked up like the top right sub http://mobile.jlaudio.com/support_pages.php?page_id=161 because right now i only have wire going to one of the terminals and nothing to the other. would it be best for me to hook it up + to + and - to- like the diagram. thanks all for the help |
|
Bronze Member Username: Matt_stuPost Number: 58 Registered: Jun-06 | but the voice coil on the sub is dvc 4 ohms http://www.ascendantaudio.com/arsenal15specs.html im new to the audio spectrum and im still trying to figure stuff out sorry for all the post thanks for any help |

Silver Member Username: Rob_pregRoyal oak, Michigan United states Post Number: 489 Registered: Sep-05 | correct, you should wire it like in the top right picture. then you would have the vc's in parallel and give you a single 2 ohm load for that amp. you should be pleased with the results when done, if you havent already messed up the driver from only having one voice coil hooked up. |

Silver Member Username: Rob_pregRoyal oak, Michigan United states Post Number: 490 Registered: Sep-05 | IMPORTANT NOTE! EVERYONE, QUIT WINGING IT WHEN HOOKING UP SUBS. IF YOU DONT KNOW EXACTLY WHAT YOU'RE DOING, GET HELP. QUIT ATTACHING SOME WIRES TO SOME TERMINALS AND HOPING FOR THE BEST! GOD! |

Bronze Member Username: Matt_stuPost Number: 61 Registered: Jun-06 | thanx for the help and im glad i read this thread before i did do some damage to it. glad i havnt been playing it that long or that much. just out of curiosity what ohm load would my amp have been seeing with the sub hooked up that way? |
|
Gold Member Username: James1115Ct Post Number: 6435 Registered: Dec-04 | hooked up like the top right it would be a 1 ohm load. |
