Does W-D-W sound any better than a stereo rig?
Years ago, I temporarily had three Atomic CLR FRFR speakers around my studio that I plugged into my Axe-Fx.
The first thing I did, as you might imagine, was try out a W/D/W setup. It sounded awesome. However, I had the same question as you, so I setup two patches in the Axe-Fx, one had all three cabs setup in W/D/W config, and the other was the same patch but setup with stereo effects and a dry center tone, only using the outer CLR's, no signal at all going to the center one.
There was *literally* zero difference between the two patches. In fact, when I physically moved the center speaker away from the setup, my brain was convinced there was still a center speaker sitting there, thanks to the dry signal being panned center (and the excellent detail and balance of the CLR's).
I think W/D/W setups were designed for two scenarios:
- The first is for non-master volume rigs, or rigs where you turn your master volume high enough that the poweramp of your dry tone starts to clip. For these setups, putting your wet effects through a separate, clean poweramp can really help keep things clear. For example you might not want to put a delay or something in the effects loop of an amp that is blasting so loud that the delays get distorted. With a W/D/W setup, you could crank a plexi in the center and still have your delays come out clean through a separate, more powerful stereo amp that isn't distorting.
- Hobbyists who can walk around their amp setups to hear the "3D-ness" of a W/D/W setup without having to worry about stepping on the toes of band mates, hah.
Having said that, I still use a W/D/W setup at home sometimes just because it's fun and I like the engineering challenge of running it. But if you have a setup that allows to you get the tones you want without distorting the amps that power your speakers, then yeah there's barely any difference at all between a W/D/W and a good stereo setup for most practical uses.
However, if you want to get weird with it, like putting your center speaker relatively close to yourself and setting up your wet cabs physically far away to really exaggerate the effect, then that's probably something you won't be able to 100% replicate with a stereo rig.
