What are the things that look like speakers? I like their semi-transluscent style. Where are they from?

The storage bins look just like Ikea's Trofast bins, but I don't know if they used actual Trofast shelving units, or if they made their own. I would love to know what they did - it's the perfect solution for Lego!

Please could you confirm the manufacturer / source of the storage bin system? That would be awesome and very much appreciated!

In a comment thread below the designer (architect? builder?) said:

"the storage is a mixture of IKEA (the uppers) and Sterilite drawers (the lower storage). We designed custom shelves and racks to hold them all"

So that would mean Trofast bins with a custom system to hold them (there are lots of DIY tutorials online for these units (basically shelving units with slots)). Sterilite bins can be found just about anywhere (Target, Michael's, etc).

Such a lovely Lego solution and I am jealous! We must do this to a wall in the playroom.

The storage bins are indeed IKEA Trofast bins with custom shelves made to work with them.
The things that look like speakers actually are speakers! There's a drop down screen and I forget where the speakers are from.
