Sub-bass vs. Physics

I think I might of asked this already...
If you have a sine-based bassline with overlapping notes and you get some interesting patterns with phase, where one note causes phasing on the tail of another, is there a risk there technically (vinyl cutting, sound system with no limiter, hypothetically)?

From what I remember from physics you can have waves cancel or, in the other extreme have standing waves, but it's somewhat unpredictable. Maybe my memory is tainted, but had a case where I had a bassline running with long release on the notes and how one note interacted with the following note intrigued me and just trying to figure out if it's a non-runner on a technical front?

But maybe I'm overthinking things or have shit mixed up...
Anyone got any input on this? ..

I think ive read somewhere that it could cause hemorrhoids, but life is more exciting when youre living on the edge.

That phase cancel problem only happens if theres a SAME wave INVERTED. If it's not like this, it gives you some chorus or flanger-like sound and it's shit.
But... if theres a duplicated wave (identical)... then... the magic comes 8-) 8-)

It`s not really an issue, but you may get cancellation or wave doubling.
If you are controlling your bass with compression (as you should) then all will be fine (unless you don`t want phase cancellation/nulling).
Obviously keep the lows in mono if you are looking for vinyl as you end destination (and it just keeps shit tighter anyway).
