I apologize for such a stupid question but I have recently come across a pair of Altec 288-8kvcompression drivers and Manta ray horns. These drivers have only a 15w power handling capability. I'd really like to be able to drive these with my Dynaco mkiii's is 60w too much for them? I know if they were low freq woofers this would not be much of a problem but I'm very new to compression drivers and don't want to harm them. For what it's worth, I listen at moderately low listeling levels for the most part.
