Here is my gear one avatar 210 cabinet, and an avatar compact 115 with horn speaker cab. Both cabinets are 4 ohm cabinets. I am playing through a peavey 700watt fire bass head. With both cabs it is a 2 ohm load. Which the firebass head should be able to handle. My usual bass is an OLP stingray 5 string. I sometimes play my Ibanez 406sr. I notice that on the open b, and up to the sixth fret. I get some distortion. It was my under standing. That lower notes need more power, or clipping occurs. I notice the distortion happens mostly at lower levels. Is this a cab question or amp and power question? What do I need to do to prevent this from occurring? Or am I completely missing something?
