[QUOTE="Bob Harvey, post: 107586, member: 2052"] Re: JBL PRX715XLF Powered Subwoofer - Excessive Fan Noise Hi Spenser: The isolation (or lack thereof) of the fan from the enclosure and/or amp panel may indeed be the culprit. Where's my screwdriver? [SIZE=5]☺[/SIZE] I have filled out the "contact us" form on the JBL website, but no reply yet. Also, my dealer is going through JBL's rep to follow up on the excessive fan noise. After Keith said that his db reading was somewhat lower, I noticed that the fans run at two speeds ... idle and faster when there is program audio present. My readings were just when audio program had stopped and the fans were at full speed. Both subs had similar readings. Thanks [/QUOTE]
