Anybody know what the typical power rating should be for a tweeter in older Epi cabs? I'm looking to replace the tweeter in an old T210 and the original is not marked at all. I know they used P-audio drivers at one point. This appears to be the same driver http://www.usspeaker.com/paudio pht-406-1.htm but I'm a little concerned about the 20W rating. Is this high enough for a 400+ watt cab? Thanks in advance for your input.
