John, They cited 20.2.1 -
"Requirement: All circuits where the available power exceeds 15 W, and their associated components, shall be contained in a fire enclosure." "Observation: The enclosure construction has openings under the power supply and amplifier circuitry. Such construction is not considered a suitable fire enclosure. In order to comply with UL 60065, these bottom openings must be removed." I just realized I was excerpting the UL version of the standard and their test report says it was done to EN 60065. I don't think it makes much difference though.
