610 cab wiring

[rptrsn2]

Have a empty 610 cab, what ohm speakers and wiring configuration would make this a 4ohm cab?

Then you will need drivers with an impedance of 2.7ohms.....

But, with 6 4ohm drivers you can create the following impedances:
-6ohm
-2.7ohms (you need a 3ohm stable amp)

With 6 8ohm drivers you can create the following impedances:
-12ohm
-5.3ohms, (this is the impedance you'll see with most 610 cabs)

To get 5.3ohms all you need to do is create three pairs of series wired 8ohm drivers and then wire these three pairs parallel, got it?

or all 32 ohm drivers in parrallel is the same 5.333 ohms
such as the legend b810

If you want 4 ohms, you need either 6 ohm speakers (in series/parallel) or 24 ohm speakers (in parallel). The only one of these options that I know of that is commercial available are the 6 ohm speakers for the ampeg 610HLF available here for $90 or here for $125. The issue you'll run up against is that those speakers are designed for a specific cab volume and porting. If the cab you have has similar dimensions to the 610HLF then I'd say go to town, otherwise, you're in a tight spot for replacement unless you can find someone willing to do custom spec speakers for you.

Theoretically you could wire a bank of four 32 ohm speakers in parallel to get an 8 ohm load, and then wire another bank of two 16 ohm speakers for another 8 ohm load then wire those two banks together in parallel to get a 4 ohm load. Tjough admittedly i dont know how that woul look in practice.

[BogeyBass]

as mentioned you either order custom wound voice coils and run series/parallel

or just run 6x 32 ohm speakers and run that load and not give a hoot or freak out over a ohm or so.
its really pointless

common off the shelf 32 ohm drivers are the Eminence Legend as mentioned
or the Eden special design speakers Eminence CA1032

Likewise for a 13% upcharge Eminence will wind any value voicecoil within reason for most models.

So you coud use something straightforward like a Basslite S2010 and have Eminence wind them to whatever impedance you want.
just contact or Email eminence custom shop

also Keep in mind that a " 8 ohm" nominal speaker will have a DC resistance or (Re) of 5 to 6 ohms.
so whatever makes you feel better

basically you can run 6x8 ohm speakers series /parallel and call it a day
or run 6x32 ohm all in parallel and call it a day

Rated impedance is a purely nominal figure, and the actual impedance varies with make of driver, frequency and even cab design, so the 6 8ohm drivers in series parallel makes for a perfectly reasonable nominal 4 ohm rating.

Bad idea as the power distribution will be out of whack.

Six 24Ω drivers all in parallel with get you to a 4Ω total impedance.

The point is moot however as the OP hasn’t shown he face here since April 14 2014!
