4ohm to 8ohm

now now ... it can be done, but you won't like the result.
big 4 ohm resistor inside the cabinet, and all that.
OP -- generally one cannot readily change the impedance of cabinet and get something useful.

It's a matter of replacing the woofers, which means that it's probably more cost-effective to sell the cab and get what you want.
Yes.
No, but it can be done. One hundred Watts maximum unfortunately, at least with Link Removed example. Scroll down to WZC-100.
I hate to be a prick, but if you're asking this, then you probably shouldn't do it. It takes a decent understanding of ohm's law and a good understanding of series and parallel circuits/wiring.
The short answer is, yes it can be done, by adding dummy loads or a complete rewire (depending on your situation). Is it recommended or will you be happy with the results??? (read above paragraph)
If it's worth it for you to spend about $300, you can convert it
with an impedance transformer.

No. And don't listen to those who finagle some way to say it can. There is no practical way to do it, and those saying anything but "no" are just farting away precious internet bandwidth. So no.
This is exactly what I'm talking about. Adding dummy loads would be dumb. A complete rewire means rewinding the voice coils of the speakers, not rearranging the wires between the speakers to series, series/parallel or parallel. It doesn't matter how well you know Ohm's law and wiring. There is no practical way to do it. So no.
Yes BUT it is not a matter of simply rewiring, the easiest way is to replace all the drivers with 8 ohm units and wire them series-parallel. Using a resister inside is not a good option as it doesn't behave like a driver for the amp and may produce undesirable results. The matching transformer will work with less power loss but is VERY expensive. 4 new drivers are going to cost quite a bit also, I think poster #4 said it when he recommended selling the cab and buying an 8 ohm cab as this will usually be cheaper (individual driver prices are much higher than cab manufacturers pay) than buying 4 new drivers and replacing your existing ones.
More than likely four 4 ohm drivers in the cab ... if in an emergency we have disconected two of the drivers and the remaining two were wired in series, and the end result was 8 ohms .. but certainly not ideal, and absolutely not something you want to do by intention as the cab is not designed for it ... we did it to finish out a night
... it would work if there were 16 ohm drivers also, two speakers parrallel would be an 8 ohm load ...

Similar to the matching xformer posted above but at a better price. They do work and are available. Handles up to 400Watts.

I've installed many of these with no ill effects. If Jack Sondermeyer (Peavey engineer) said they work, they work. It's no different than a tube amp having an output transformer to match impedance.
