In a smaller room (16 x 11) in the basement corner where those 2 walls are block. The interest is to build walls in front of the block walls which should help out with acoustics .

The concern is low bass and I see the drywall partitions as bass traps of sorts.

What if the walls are not sealed to the block walls?

Would there be any benefit if the partitions were sealed every 4 ft (like big bass traps but with a continuous drywall panel)?

24" O.C or 16" O.C?

1 layer of drywall or 2 (with Green Glue)? This seems like it would lower the frequency of the trapping in the partitions.

Would Green Glue make the panels of the wall behave more wide band since they can't resonate as they usually do?

I'm pretty sure that building walls with the hope of membrane absorption won't be any better than just using the same space for conventional bass traps. If you're up for experimenting, I won't discourage you! But I'd do it by building sealed membrane traps onto the walls, rather than a normal wall.
