The DS15 SE's 18"x18" foot print makes it too big for a single 15" x 15" Subdude, or even a 23" x 15" GRAMMA. Because the DS15 has built-in legs, overhang isn't an option like it is for a box sub, or a cylinder with a flat bottom.
Anybody have their DS15 sitting on an isolation riser? If so, what did you go with?
Obviously, I could use two GRAMMAs, but don't really want an 18"x18" work of art sitting atop a 23" x 30" riser. Then again, might not be the end of the world.
Are their better options?
