Why does the 400-PS have three 145 watt speaker outputs?
NOTE: The long version requires reading the short version first.. Billy Cox is using six Guild Quantum Bass cabinets with two JBL 15″ speakers in each of them.

How do you think today’s popular four 10″ bass cabinet with the same 600 watts is going to perform in comparison on that stage? Imagine yourself with this 4×10″ cabinet of “Power Pistons”, trying to replace those six Quantum cabinets on stage, with that same 600 watts for power.

The reality is, you will be placing a 150 watts on each of those 10″ speakers, while Billy is only placing 50 watts on each of his 15″ JBL’s. Billy could easily double his power delivery without risk of speaker failure. Now stop and think… how many more A
