The db750 is 2 ohm safe and at that point is a monster!!
Yes, 2 will handle most of my gigs.
Most of my gigs are small ( specially this time of year)
But in the spring and summer I do lots of festivals and outdoor events so 4 would be awesome!!
Actually, I just had an idea!!
Maybe I'll add 2 210aV's sideways on the top of each and have 2 112s and 2 av210s and a totally modular component system!!
