Downfiring amp, raised.

So I recently started using an Acoustic Image Contra, first series. This is an amp with a downfiring woofer and a forward facing mid. It is intended to couple with the floor and if you put it on the floor it has very strong low frequencies. But if I put it on the floor, the mid is firing at my calves.

So, a thread over in bass guitar land made me think of a possible approach -

Why couldn't I set a milk crate down on the floor, then put a piece of plywood on that, then put the amp on THAT? Wouldn't that do much the same thing as the floor, but 18" or so closer to my ears? I already use the piece of plywood on my folding two-wheeler.

Any comments?

 

So I notice that you have the amp up on little legs. Is the additional spacing between the reflective plane and the speaker (compared to setting it on the floor) needed because of the small size of the plane compared to a floor?

I had not thought of raising it that high. It's true, though, that my thighs don't have ears any more than my calves do. I would be concerned about it getting knocked over, though.
