mmmm This is making me reconsider a line array PA setup! I've recently been looking into that newest batch of Turbosound loudspeakers. Your comparison of the DXR10 & Bose L1 makes me reconsider a bit.
But I've also heard from DJs, and this may just be conjecture mind you, that one could invest in a higher grade of 8" sub, and still get comparable, if not better reproduction of LFE in the form of more affordable brand of 10", 12", 15" iterations. It's just a matter of form factor having better performance I think I'm saying? That's only one point being made when discussing subs at least. Doesn't make the case that the higher quality 8" is incapable of quality sound, but perhaps is comparable to... buying a porsche with the expectation of pulling a trailer. That actually is probably a bad side-case/example, as in our case, either speaker is built for the same utility.
But aren't line-array setups proposed for their ability to project sound in a better perceivable spread so that it may remain audible to an audience? To also include options that assist the performer regarding feedback issues (not an issue perhaps, in the case of a kemper, but with mics I suppose).
I'm questioning you, simply because I've been considering a line-array setup for the purpose of casual listening and the bonus of running my kemper through it. That and the formfactor of the usual PA system has always been offputting. But the pricing I'm looking at is around the same, and I may very well go for something such as the DXR10! Just not entirely certain at the moment now : /
Not the point of your thread maybe, but still I ask! xD
