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!

Neither of them should be bass limited in useful range ie 20Hz above. But record has higher dynamic range and usually is harmonic rich. Therefore, you feel the impact of bass plus lots of harmonis with a drum without compression due to the "big" dynamic range. A CD can go very deep of course, try organ, but it usually has less hamonics than the sound pick up by a needle. Actually a drum covers not only bass but also lots of info and energy on its rich harmonics, i.e. it not a sine wave. And LP is good at picking up those harmonics (or some may say generating?)

There is no fundamental limit CD can't carry 20Hz data. The "feel" of not much punch is, IMO is due to the limited dynamic resolution and the less harmonics in CD playback. That's why SACD will have more punch than CD. And your ears tell you that LP gives you the most "WOW" punch. And it is a closer one to the live drum beat in orchestra.
