Hey there, A quick naive question for you all. Why are most 2x10 cabs rated lower than 4x10's? surely if i put a 200w 210 with a 410 running from a 400w head it would damage the speaker? Sorry if this is a horribly obvious question, but i'm just learning about all this! and which is better, a hartke vx410 or a Gallien backline 410? (which is also £120 more!). thanks, phil.
