[QUOTE="Peter Morris, post: 148374, member: 652"] Re: 60 Degree DIY Mid Hi Yes but the AES measurement is calculated from the RMS voltage squared divided by the minimum impedance. So if the load was a resistor the AES and "RMS" power would be the same. Accordingly the AES and RMS ratings are similar. The AES measurement uses one octave of shaped pink noise. I think the RMS test was done a 1KHz ... Given that the AES is made in free air, its arguable the power handling should be measured in the actual enclosure over the nominal operating band, and referenced to the nominal impedance ... similar to what EAW do - [URL]http://eaw.com/docs/6_Technical_Information/StudyHall_and_TechNotes/Power_Handling.pdf[/URL] [/QUOTE]
