Looking for speaker stands that staddle a sub ?

I am looking to add a second sub, I have revel m22's for mains, does anyone have any info on speaker stands that are designed to straddle a sub, I have limited space options,my sub is a JL 112, thanks

If I'm understanding what you're describing, you want to place the subs below each M22, right? One of the advantages of sat/sub systems is that the bass can be located independently of the mid/treble so that a smooth response can be attained from each. It's unlikely that placing the subs where the M22s are will yield smooth bass.
