Level the floor

We've just moved.  The audio playpen is the basement, which has an issue I haven't dealt with before: uneven floor.  Left-right is level, but front to back there's a steep slope.  At a distance of 18 inches, the slope is about one inch.

I figure others have dealt with this enough that there's "a way" (or an eternal argument...).  Educate me?

Available equipment would be fine; surprise uses of stuff would be terrific.

Thanks.

That’s a big slope but just because the basement floor sunk or rose in as area, doesn’t necessarily, & hopefully not, mean the foundation walls moved. They’re most likely not contiguous.

A slope of 1 inch every 18 inches?  Across the whole length of the room?  How is your house still standing?

I know, right?  The neighbors to the north have been astonishingly understanding.  I haven't checked with Canada yet, they're busy.

This is a common shape on houses here.  19th/20th century Illinois; when they were first built the basement was not a useful floor, so much as a "bottom".  The concrete was poured in sometime after, with existing pipes and whatever already in place, so a perfectly level floor would have led to a ceiling hitting heads.

It's not sinking, it was made that way.

So my basement, home of my Man Cave, slopes down towards the sump pump well.  That saved my amp, subs and speakers when we had a flood in 2007!  Don't level your floor unless you are certain that this isn't an issue.

 

I don't really level much except the speakers, which have adjustable spikes on Sound Anchor stands, and my Thorens TD166MkII.  I had custom feet installed to replace the stock feet.  These have a leveling adjustment range of about 2", and have racket balls on the bottom in inverted cups.  I must replace the balls whenever the old ones lose their elasticity.  But according to several bubble levels, the 'table is completely level.
