I tested the zxa1's against the liveX 112's that seems to be one of the popular accepted standards. Both were powered versions of course. Both were run in stereo, at LOUD volumes - they actually came in the store and told us to turn it down
Overall, the 112 sounded better, but not by much!
It had a fuller sound (obviously) but there was a definition in the zx's that was not noticed in the 112s. LOTS of bass in the 112s, but like I said, I chop off bass frequencies like if my life depended on it - everything from at LEAST 80-100hz gets chopped off, whether I'm playing guitar OR bass!
The zx's crapped out at much lower volumes, but still sounded pretty good, even when clipping, which was kinda shocking......you can obviously tell that they're clipping, but it's not as bad as you'd expect. The 112's were REAL loud....and had LOTS of headroom.....LOTS!!! I can't see you needing much more power than that live to be honest, unless you're playing stadiums....
initially I had run some pink noise into the zx's to see the response, and they are pretty flat!!
dropped steeply off somewhere between 50-80 hz, but I chop that freq off anyway - it's more felt than heard. I didn't get the chance to do the same with the 112s, but the response was very close to the zx's, so I can imagine that they're just as flat, or flatter. At lower volumes, it's hard to tell which is which.
Initially I was going to go with the 112s, but when we turned up the bass on the zx's, I was really impressed! Those little boxes have some SERIOUS punch!
Can't go too loud with them before they start to clip, but at decent volumes they proved to be great! I think by adding in some bass in the global eq that you can get a VERY flat response from them. Vocals seemed to favor the zx's as well. Oh, and when I say decent volumes, all these tests were done with TWO drummers pounding away in the back!!! And the store is in the middle of a VERY noisy family entertainment complex.....so for the guys in the loud rock bands, these should still work pretty well.
If you add a sub to the zx's, (they actually have a feature to cross over to sub as well), I think they might actually sound better than the 112s.
I plugged them into my system home, and compared them with about 3 PA's. They did better than I expected, and I am eager to use them now
So which did I chose? Well I have one of the zxa1's home right now, and I'm going to get another to run in stereo....can't live without stereo! LOL The nice thing is that they are so light and compact that you can walk with the pair to a gig, and have everything in full stereo, which I intend to do....one trip to/from the car with both of them. Awesome!
Hope this may have been some help to anyone else thinking about them.
