OK it seems the barefaced fanbois have not arrived yet, so I will dive in...
As per Phil's advice, go try lots of stuff. But don't forget to try barefaced 10s and 12s. You will not be disappointed.
I recall having a similar quandry a few years ago, and took a punt on the new barefaced four10. I wasn't sure it would be enough so I took the 8-ohm version so I could add a second.
In hindsight a two10 would have done the job. This gear is unbelievably loud, weighs very little and is very well constructed. They have a wide range to suit your style too. Go try em.
