Yes, i know it is, and understand the idea and usage, but i don't have any and didn't need them when i started and bought all my cables.

Nice one! Down here, every bloody shop you go to now, has to have large sign telling you that the place has forms if you want to complain about service, or products. No longer acceptable to just punch the assistant!! |

The matrix wrote nothing so I guess it's ok to have one amp channel running hard and one without any load then!

Yup - or even use different signals on each channel, eg bass on 1 & 2, mid on 3 & top on 4! |

The Matrix didn't write anything because an amp has no thumbs, thus, Matrix can't hold a pen, it don't look happy... |

NL8/8 core or EP6 or Socapex for real rigs.
Any way, away from that efin' shite, and back to OP: My only fear of using an amp channel per driver is a bit theoretical, and only in a worst case - if a cable core fails, then the motion of the one driver still working, will flap the other one. Same if an amp channel fails. Perhaps moot, as by this point, you have bigger things to worry about, but a potential draw back, which could make a bad situation worse? Potential for something similar if an amp gain pot is different to the other, or if your feed to each amp channel is different; say you feed balanced signal to each channel, and a core drops, so 6dB difference in amplifier output. The "louder" cone would try and move the quieter cone, feeding back EMF into the quieter amp channel. Given that most amplifiers have to absorb some degree of back EMF anyway, shouldn't be too much of an issue. If your amplifier has a "parallel" switch, so signal at input A is shared equally to A+B modules, then that would reduce any small risk. This is not the same as "bridge" mode, but often it is the same 3 position switch, depending on amp manufacturer. RTFM. But, until you get a big enough amp to drive it at 4 ohm per amp channel, no great issues, and the above is the only drawback I can think of. If you use fat enough/short speaker cables, driving speakers at 8 ohm will, in theory, keep the damping factor (the "grip" an amplifier has on an attached driver) higher than driving at 4 or 2 ohm, so may offer some benefit. Whether you, or I, have ears that would hear the improvement is open to debate. |

Mine is set up bass on 1&3 tops on 2&4, I was advised to do it that way to take the strain off one side of the Amp I have the The T.Amp Tsa-4-700

Well my wife has kicked me out saying it's over due to my obsession with speakers don't know watt I'm gonna do with no ohm to go to
