[QUOTE="Silas Pradetto, post: 30852, member: 34"] Re: Jbl prx618s-xlf Yes, of course. The 2268H(or FF) can handle 800W RMS, and JBL tests their woofers for 100 hours with 6dB crest factor pink noise (peaking at 3200 watts, 800 continuous). So unless someone was playing a pure sine wave (1000W) at full clip, the woofer would be fine. And in that case, I think the [I]amplifier [/I]would thermal before the woofer would toast. I owned four SRX718S back in the day and they could pop the breaker on two bridged RMX2450s with never a problem with the woofers. Only time I did cook two 2268s was when I played dance music at clip through an IT8000, with no limiters, for 3 hours. The woofers failed 10 minutes from the end of the show. And I know that just because the woofer can thermally handle 800W, it doesn't mean that the rating is not already beyond the threshold of diminishing returns. That is, the power compression at 800W may already be higher than the power compression at 400W by an amount greater than the increase in output by doubling the power....so the woofer theoretically could be louder at 400W. Of course, my assertions here are purely based on my experience with the 2268; if they had to, I'm sure someone could find a way to destroy a woofer in a PRX618S-XLF, just to prove me wrong. As of now, though, I haven't heard of a 2268 failure in a PRX618S-XLF. [/QUOTE]
