Question about Pink Floyd drummer (Nick Mason)'s set

[master of tacos]

Hey, diehard Floyd fan here, but I have a question about parts of Nick's set and maybe you can help me out here:


what is that black table-like thingy at the way left of the picture just above the floor toms? I'm guessing it might be a xylophone or something but it could be something for the mics?


What are those two cylindrical shaped drums (if they even are drums) with the speaker thingies at the bottoms by the floor toms?

Here is a closer look at them:


any info would be helpful. thanks!
