[QUOTE="Andrew Prince, post: 82071, member: 1808"] Re: JBL SRX / QSC PL236 underpowered? This is interesting and pretty much backs up my idea that the amps are not delivering enough power to get the best out of the system. This paper looks old and it's also how things were 20 years ago when I was at Uni: [url]http://www.jblpro.com/BackOffice/ProductAttachments/lowpower.pdf[/url] However, one would have thought that JBL would know exactly what to drive their own boxes with and so if they did powered versions of the SRX system, those amps would be specified perfectly to the drivers. The VRX system looks to me like a replacement for the SRX, yet the spec sheet shows they're installing low power amps in their powered versions. See it here: [url]http://www.jblpro.com/BackOffice/ProductAttachments/VRX%20Brochure_082009_web.pdf[/url] (on the last page) You can see for example that the VRX932LA-1 has the same spec as the SRX715 (800W continuous / 1600W program / 3200W peak), yet JBL themselves install an amp with 875W continuous and 1750W peak.
