These computer speakers are actually NOT made for playing instruments through. I sold my Z5500 because of the lack of mid-range & all the thin wires, remote control etc etc just too annoying to set up. Im in the process of trying out two Roland KC 150 Kb amps with the stereo link. They really sound clear and more then enough power using one or two. Quality build also.
Or I will also try two powered Mackie, FBT, Yorkville speakers as I try to come up with the perfect combination of gear to perform with for me hopefully in a few months..
