JBL PRX618S-XLF vs. SRX718
« on: January 18, 2012, 10:18:05 am »

Hey all. I'm new to these forums, I hope I'm posting in the right section. I'm a mobile DJ with 2 PRX618s-XLF's and 2 PRX615m's. For the price and weight, I think these things sound pretty damn good. For a larger rig sometime in the future I wanted to add 2 more XLF's and a pair of 625's with the 615's as side fills. My question regarding the XLF's vs. The SRX718's is mostly about the specs.

The max spl of the XLF's is rated at 133 db, but it doesn't state if that's at half space, full space etc. Same goes for the SRX718, which is rated at 130db. Does the XLF really get louder then a properly powered SRX718? Owning the XLF's, they do get pretty loud. I like them a lot more then the QSC HPR181i's I used to own. They seem to get louder and deeper. The HPR181i's also seemed to get a little sloppy at their limit while the XLF seems to hold up better.

Basically my question is, are both the XLF and SRX718 subs rated the same way? And if so, why is it that the XLF would have a 3db higher spl rating then the SRX718? Is that all because of the box size? Has anyone compared the two as far as output goes?
