What is the equivalent to a JBL Eon 15 G2 speaker?

hi x x ....the new equivalent to your eon 15 g2..... is the next gen jbl eon 315 280w continuous/560w peak output, this is a "300" series....the other you mentiond is the "500 series" - jbl 515 which is 450w continuous/900w peak output...other manufacturers that are comparable are rcl,EV,mackie just get on to their web sites and do a comparison relevent to the wattage output on the above mentioned...hope this helps.
