mr optimum balance first came to the attention of this forum in this thread.
his barrage of useless insults is actually better than his barrage of useless jargon- at least it's clear what a muppet he is there. boyd was funnier. ToXiC had his moments. what's OB got? |

the only thing more dangerous than a person who doesn't give a f**k is a person who gives a sh*t.

The option of using series-parallel wiring is an interesting one.
In the past we've (collectively) come to the opionion that its ok for driving large numbers of speakers from an amp, say in a bar/corporate environment for speech etc, but not for driving bass in large scale application, partly because of loss of DF, but also because of the complications of changing wiring schemes without any significant benefit. As the original poster has enough amps, he can achieve equal power using regular parallel wiring.
E.g.
Cab wired in series is 16R, in parallel with another cab is 8R. Bridged 707 gives 1650 at 4R bridge meaning 825w per cab
Cab wired in parallel 4R, in series with another cab is 8R. See above.
Cab wired in parallel 4R, 1 on each side of the 707 is 825w. No wiring changes or complicated stuff to do.
Care to elaborate why you feel this is a good option? Edited by norty303 - 08 October 2008 at 5:51pm |

You're a big man, but you're in bad shape. With me it's a full time job. Now behave yourself.

user 2x18 must be even more confused after the hilarity of this thread! If you've not been scared away from this forum forever 2x18, here's some simple advice without the over-technical nonsense. 825w per channel seems quite low for running two 18"s regardless of the load. I would definately give your drivers slightly more watts than they need (which will mean investing in more powerful amps) and restrict the signal db at your crossover to account for the extra power. Although the tolerances of the system will become more sensitive, you will get a better response overall. Your current amps will be working very hard with this setup and will probably protect/overheat quite rapidly should you want to run it hard. To help your query, if you're dead set on this setup, switch your amps to parrallel and run one cab off each channel. If you have the option, use the link output of your first amp to send a signal to your second amp. You will then be sending a matching mono bass signal to each cab. Although, as norty303 pointed out, running bass using this (parallel) method isn't ideal for large applications, I feel it will be more than adequate in your case and makes more sense than running your bass in stereo.
