For 412 cabinet in stereo, do two of the speakers need to be in phase and two out. If so how do you do that?
Thanks. |

i think there is every possibility of wiring a 4x12 here, watch out for your Ohms ratings, get it wrong and it could be expensive. |

| do you mean wiring the + on one terminal of one speaker to the - on the next speaker and then on to the amp output? and then the - on the other terminal to the + on the next ? you should never do this unles you require a push/pull isobaric alignment, some dual driver sub-woofers require this, maybe bass could elaborate on this one? i think there is an out of phase series and paralell too. |

Twizza, just in case your 'notify me' is switched on, I did a new topic called "Some impedance theory". There is also yet another thread on the subj from Riz you may want to read. Blimey, Chinese whispers.
Did enjoy that isobaric something. I tend to forget the importance of keeping the atmospheric pressure constant  Must give up smoking. |
