Hello. I am new to Talk Bass.com. I play through a Gallien-Kruger MB500 with a GK 4x10" Neo cabinet. I am considering a smaller cabinet because I usually play smaller venues now. GK makes bass cabinets with a choice of either 2x10" single 12" or single 15" neo speaker options. What is your opinion on which would be the best cabinet for a smaller cabinet choice? Also, would it be OK to use my 500 watt amp with these cabinets (they are 300-400 watt cabinets). I may be playing at a place that has a second story and stairs. I am retired with a spine disease and weight of my equipment is becoming an important consideration.
