Connecting both channels of an amp
The reason for dual voice coil speakers is to give added flexibility
on the loads of the amp..letting one adjust let's say from 4 ohms to 2 ohms..and the same for dual 8 ohms coils you can switch from 8 to 4....but as for connecting each voice coil separatly...I'm not sure...i know it's an absolute no-no in stereo configuration where each channel is getting diffrent signal..that is obviuos.. The first few posts are missing from my news feed, however, I must correct the above. While one could use the multiple coils for impedance matching, the most compelling reason for two coils is to accept a stereo feed from the amplifiers when you have only enough room for one speaker. For example, in many small bathrooms there just isn't any space or budget for a second speaker. The two channel speaker allows one to use the same stereo amplifier feed to operate stereo and mono rooms without going to a lot of fuss. The most optomistic outcome of connecting two amplifier outputs in parallel at a speaker is a mono result. Typically, the amplifier is destroyed. If the amplifier somehow survived, all of the rooms would be converted to mono. If one wants to fuss about the last 0.00x percent of performance, the dual voice coil approach is probably not the thing to do, but in multi-room or subwoofer duty, it usually doesn't matter. ---- If you are using the dual voice coil speaker as a subwoofer, the line level subwoofer output from an A/V receiver is usually mono, even if there are two subwoofer output jacks. In this case, connecting both coils will increase the output a bit. If you accidently connect the voice coils out of phase, there will be very little or no output from the speaker. (assuming the output from the amplifiers is identical) ----------------------------------------------------------- spam: wordgame:123(abc):14 9 20 5 2 9 18 4 at 22 15 9 3 5 14 5 20 dot 3 15 13 (Barry Mann) [sorry about the puzzle, spammers are ruining my mailbox] ----------------------------------------------------------- |

material in one channel differs from the material from the other channel..could destroy your subwoofer... Care to explain how? If a speaker receives two diffrent signals on it two coils..which way will the woofer move..to which sound..first.... The woofer will move in the direction that the magnetic interaction specifies. The magnetic forces exerted by the coils are non-separable. Since each coil sets up a magnetic field, the fields for the two will basically sum, and the result is essentially the vector sum of the magnetic forces. This resultant force will be applied to both coils. So I'm not quite sure how your argument translates into blown speakers. |

The forces developed by 2, 3, or 100 coils will add and the cone will follow the sum.

Actually, there is a similar issue with the air. Ultimately, sound is movement of air.

At the micro level you can show that there is some interaction between all the simultaneous signals in both the speaker and in air, but it is more difficult to prove the significance of all this when our perception processes the result. ----------------------------------------------------------- spam: wordgame:123(abc):14 9 20 5 2 9 18 4 at 22 15 9 3 5 14 5 20 dot 3 15 13 (Barry Mann) [sorry about the puzzle, spammers are ruining my mailbox] ----------------------------------------------------------- |

Connecting both channels of an amp
If a speaker receives two diffrent signals on it two coils..which way
will the woofer move..to which sound..first.... The forces developed by 2, 3, or 100 coils will add and the cone will follow the sum. You could make a mild case that, if an individual coil was driven differently than the others, there would be a tendency for the coil form (all of the coils would be attached to a single form) to be torn apart, but the forces involved are not high enough to hurt the form. I'm not so sure this is accurate. If the two coils are setting up magnetic fields, they will be influencing each other's magnetic flux. To a good approximation, this would result in the same flux for each coil, and as such they should both exert nearly the same force. This is especially true if the coils are overlapping. |
