Interesting. On paper they're very impressive. I'd like to compare them to my Proels, as my Alto TS210s are very unimpressive. That story is told elsewhere in here.
Thank you Alan. As the OP asked what we
use, not what we
recommend I overlooked that point.
And to trot out another of my oft repeated bits of advice, if I were forced to only use two boxes at every gig, they would have 15" drivers. ( And preferably be wooden, but that's becoming less vital nowadays ).
And if I weren't limited to two boxes, there's a strong argument for small subs and tops. I had a W Audio rig with 10" drivers which defied belief. If I'd had some lightweight amps and a can of paint, I might still be using them.
On a related note, if you're not playing Wembley Stadium sized venues, the new compact rigs fare well. Maui, Evox, Vertus etc.
It's worth deciding what most of your gigs require, and tailoring the rig to those. If you had a residency with a first floor function room and no lift, twin 18" subs are unlikely to be a good idea.
