How much LF info on LPs?

Hi.

I would like to ask how much audible Low-frequency information do you get from your speakers when spinning vinyl? I know that vinyl definitely doesn't go as low as CDs. That being the case, then wouldn't speakers with good bass extension be irrelevant and a waste of money in a vinyl-only system? I've noticed that big bass=big money, in general. What are your experiences?

I didn't find this anywhere in the archives. If it is there, please direct me.

Thanks!
