Why would anyone prefer having a 30 foot speaker cable instead of a 3 foot one? Miniaturization is kind of "neat" but beyond a certain point it almost becomes a pain because you have to figure out how to secure it so you don't yank right off your cab if you go a foot too far away from it. 5-10 pounds seems like the lower limit for a bass amp sitting on a cab, unless you have a convenient way to secure it (which will naturally add weight and adds cost which kind of defeats the purpose, right?).
