sunn cabinet wiring

[RNFR]

hey guys- hope I can get some hrlp on this one...


       a friend of mine is starting a cabinet company and I have neen designated to help with the wiring.  I have some limited experience,and although I have schematics for fender and marshall series, series/paralell, and paralell wiring schemes,  he wants it to be like a Sunn "where you can go in and out of either jack".  KNow what he is talking about with this?  anybody have sunn cab wiring configs?  or know what kind of jacks they used on this type of cab?  any help would be greatly appreciated.

oh yeah- we are talking 4x12 cabs here.  thanks again.

It depends on what total load you ultimately want on the amp. If you wire the speakers in each cab for 8 ohms total and wire 2 jacks in each cab in parallel, then daisy chain a pair of the cabs together you will have a 4 ohm total load. It wouldn't matter which jack you plugged what into.

Uhmm...Was that your question?

[RNFR]

i think so.. I've got to get some more info from my friend.  thanks for the reply.

were the sunn cabs wired in paralell or series/ parallel - like marshalls?

[Isaac]

The earliest Sunn cabinets had only one jack. In most cases, I think that's better, anyway. However, some people want the convenience of having a second jack, so Sunn put a second one on. AFAIK, it was always the two jacks in parallel.

In a word, yes. The wiring is dependent on the impedance and quantity of drivers, not the type or brand of cabinet. Once you decide on a particular driver array for a specific cabinet, you wire it to obtain the overall impedance for the application the cabinet is designed for. If you need an 8 ohm 4X12 and want to use 8 ohm drivers, series parallel. If you want a  4 ohm cab, you need 4 ohm drivers in series parallel, OR 16 ohm drivers in parallel. Wire to the application, don't design for the wiring.
Good Luck with your adventure.

i have a question regarding something that edbass just posted

my 610 needs new speakers. i believe that i have correct wiring diagrams for both 4 ohm and 8 ohm speakers. should the new ones be 4 or 8, and will there be a difference in sound or difficulty in wiring? thanks

Above all else, power amps work best with a single speaker.  If you have to use multiple speakers, then the power amp is better able to control the speakers with them in parallel instead of series.  Example - if I needed 8 ohms I would wire two 16 ohm speakers in parallel instead of two 4 ohm speakers in series.

Since you need six speakers and have limited your choices to 4 or 8 ohm types, then you have to use a combination of series and parallel connections.  So, I would go for more parallel connections and as few series connections as possible.

I would go with the 8 ohm speakers and parallel wire three series strings of 2 speakers each for a 5.33 ohm total load like this:

Code: [Select]

before I would use two series strings of three 4 ohm speakers connected in parallel for a 6 ohm total load like this:

Code: [Select]

Anyway... this is what I would do.

alright, thanks! i think that is what i'll do.
