Just a Question, if i was to say buy 4*12" speakers each with an rating of 8ohms. Is it then possible to wire it in such a way as to allow an 8ohm connection?

In a word no, i've just single handedly proved myself a fool i think. I've just done the resistance calculations and i don't get the right answer, ie 8 ohms? < I did electronics for 2 years and i think i have this wrong

I'm an ac repairman, and parallel resistance is

RT= 1
----------------------
1 + 1 + 1 + 1
--- --- --- ---
R1 R2 R3 R4
Which comes to 2 ohms w 8 ohm speakers x4.

Thankyou, exactly what i thought, thats why i got confused when they said wire them in parralell

Could you wire them in two series blocks of two running in parralell to each other?

woudnt a parallel conection give you 2 ohms??? im in electronics shop in school and im almost positive itll give you 2

Seems that would be a 4 ohm circuit


I'm not questioning you, but are you sure?

If each bank is in series, therefore each bank: R(t) = R(1) + R(2) >>> 16 ohms

If you run two 16 ohm banks in parralell


1
------------------------- = 1/1/8 = 8???

wire them in series parallel. in other words, wire 2 speakers in series, then wire that "group" in parallel with another "group" of 2 speakers in series. thatll give you 8 ohms

My bad....2 in series in parallel w/ 2 in series will yield 4 ohms. Series parallel circuit is right.

No worries

Right the plan is guys....

To build a slimline budget 4*12 cabinet for my blues junior. Before anybody says it is just for show on stage.

I have the opportunity to get hold of 4 Celestian 12" drivers for £60 new. As obviously discussed they are 8 ohms.

Good luck.


Sarcasm??

Anyway, does anybody know acoustically what keeping the cab depth to a minimum would do?

I was thinking about 220mm depth??

I was also thinking about keeping the cab size to a minimum about 750*750*220mm??

Or material Providing 700*700*200mm
