[quote name='Merton' post='46393' date='Aug 16 2007, 01:00 PM']Wattage is a difficult one to quantify with "how much is enough?" because it isn't a true reflection on volume, or SPL. I've used a 500W Ashdown head thru a 4x10 cab and not felt I could get an adequate volume level, but my Trace 300W head thru the same cab was fine with the volume on 3. it's to do with effieciency of the amp, of the speakers, voicings of the amp and speaker (a more "middly" amp will cut thru better than a more "bassy" amp, c.f. my Trace and the Ashdown) etc etc....
But, despite all that nonsense, I'd say no less than 150W.[/quote]
+1 on that.
