Cassp/Fran/Donny: Thanks for the replies.

I was leaning towards the Mackie (lower profile, XLR out). The stronger bass isn't critical for a monitor but useful if using it as a mini-PA I'll have to check them both out.

BTW, about output. I wonder at what ohm they are rating the output. I remember back in the 80's when Peavey played games by list everying at a 2 ohm rating so 30 watts at 8 ohms be everyone else, they rated as 120 watts. I don't know enough about the electronics to tell you if that is some of the differences between Roland rating and Mackie but it probably is. Looking at the specs, Mackie lists an 8 ohm speaker but that doesn't mean they are driving it at 8 ohms. More consistent would be a Sound Pressure rating because you would be measuring the result outside of the unit, not the output from wihin the unit. Of course that means that most everyone doesn't list sound pressure and there is probably a way to manipulate those numbers too.

As also, read the specs, get third part opinions, but believe your own ears.
