bass speakers review

Can I connect a bass amp cabinet to the Sub out on my roland 60 Kč?
I have a Roland KC 60 which i use as an amplifier Low murderer was wondering if i could connect either a 1x15 or 2x10 subwoofer so that through the subwoofer out of the way the people who gave this amp say negetive comments and distorts the volume 3 after just dont know how I configure this at least in volume 5 at all times
The subwoofer output is a connecting line level output with a low pass filter and DC blocking. You http://www.bhphotovideo.com/c/product/277629-REG/Roland_KC_60_KC_60_40_Watt.html You can not just connect a passive speaker there. You need a power amplifier to drive the speakers.
