I've just bought myself a pair of DB Technologies ES-602 line array systems and given them their fun run out yesterday. I was generally pretty impressed by them, particular the subs which are very good for their size, but felt the tops were maybe a bit lacking in the mid-range. I was wondering if it might be possible to use the 10" subwoofers to power a pair of 8" passives that would hopefully give a fuller sound. Does anyone know if this would be possible? Assuming it is, what is the maximum wattage speakers I could consider using and would they need to be 4 or 8 ohms?
