[QUOTE="Andrew Prince, post: 82185, member: 1808"] Re: JBL SRX / QSC PL236 underpowered? That's exactly what I thought too. However, I know that the band have never touched the crossover after it was configured by the store that sold them the system. I then thought maybe they connected the subs amp to the tops and that went a little awry, but the damage is in the HF driver and the tops have a passive crossover which would have protected the HF component. Remember, the amp is rated 725W into 8 Ohms or 1100W into 4 Ohms. Whichever way they connected it, I don't see how they could have pumped enough power into the box to cause driver excursion. No, this damage was caused by wannabe sound engineers and / or musicians. :) In all seriousness, I'm thinking it's more likely the compression driver was faulty from new and driving it hard tipped it over the edge. So we've gone from "bi-amp your subs for more power" to "get more tops because they can't keep up with your subs"? Crikey.... I can't keep up! :) I will be checking the crossover settings next time I have the rig set up though. [/QUOTE]
