Yes that cabinet displays 22 radios, though I do not have that many in it (yet), including 2 consoles. It is open in the back above the consoles, so displays in both front and back. I designed and built it and the other 5 matching cabinets. I have space for about 4 more similar ones with the consoles on the bottom. The cabinets are very heavy.

And to answer my own earlier question:

You can stack them at least 4 high.
