Ok, I know this topic has been discussed probably more than any other. And the intent is not create another argument. First ... a head with two mono amps will be used so there's the option of bi-amping. This is for a Jr. High ministry at Church, decently loud but nothing obnoxious. Room is about the size of half a basketball court. All instruments are fed through the PA . High powered combo amps just aren't working and get lost in the stage volume. Budget is limited so the top tier line 4x10 cabs are out the picture. Most lower end 4x10s (or stacked 2x10) tend to fart out with 5 or 6 strings when turned up. Keep in mind there will be youth playing through this set up so the chance of them cranking the bass knob is almost a certainty. So the priority for deciding on a set up is: 1) Ability to handle abuse 2) Fidelity 3) High volume (a distant fourth) I'm interested in those who have used both set ups and how the 210 / 15 compares to the 4x10. I have a line on a 600w 15" cab (free) to pair with a 2x10 that would have to be purchased. PLEASE ... no argument for or against, just actual comparison results.
