Alto TS112 vs EV ZX1 vs EV SX300?

Does anyone have any experience with more than one pair of these speakers?


I've been reading up various reviews and looking at the various specs.

From reading these specs the ZX1 is capable of going down to 48Hz!? I'm quite surprised at this because it only uses an 8 inch driver!?


Can anyone comment on their experiences with some of these speakers?

I don't really trust specs!


We've got some SXA100s in a 100 person capacity breakout room. They've been reliable, and they get the job done for speech / video playback, but they are very bass light and they crap out pretty early. I mixed in a venue with a distributed ZX1 system last year and while I wasn't putting any kick drum through, it certainly sounded like it had a bit more headroom and a more pleasing sound.

I would take any frequency response quoted to -10db with a pinch of salt. -10db is pretty much switched off and certainly of almost no practical use. More useful is the +- 3db response curve. I've used both of the EVs and they have been fine for speech but for anything other than background music you would need subs.

We sell more ZX1s than any other speaker in the list you provided. And there is a reason why.

The Zx1 is a fabulous speaker which we also chose for our hire stock, we've used it as a PA box, wedge monitor for small gigs, front fills, delays, you name it. The bass response is very good considering it is only an 8 incher, it's smooth, it's small and detailed. Less harsh than the Alto which IMO lacks the same smoothness of the EV, especially in the mid-range and required more EQ to get it sounding like an EV which you can run flat.


Forgot to add - you need to ask yourself is a 90x50 box better suited for your application than say the 65x65 for example
