I've wanted to bring back the console electronics. To that end I have built a few things along similar lines for myself.
A couple of thinner "speaker tables" with a small subwoofer + plate amplifier built in and a pair of full-range drivers. Not really a full console but does keep the wires to a minimum [1]. Just add an amp and sound source. (Sub is down-firing and underneath — so not visible.)
I built a taller version with storage for albums underneath (now we're getting closer to a console stereo [2]. (Sub is also down-firing.)
Additionally I built one for the TV that has a mid (full range) driver as well. With the integrated sub it's fully 3.1 with no external wires [3]. (Like previous, sub is also down-firing.)
FWIW, the "cavities" allowed for the drivers within the body of the furniture were designed to match the drivers in terms of volume (usually sized for a bass port as well). So there was a little more thought than to just slap speakers on a box.
Tried to find a build photo — this is the taller stereo version being built. Full-range drivers on each end, dual subs left-center, bass port in center, plate amplifier (for sub only) right-center: https://imgur.com/ZZtP2qp
That is excellent! I followed more of the 'just slap speakers in it' method - I have an old 50s record player that I got as a teenager (in the 90s) the bass on it was stunning, so I played it to death until the values blew.
I then emptied out the insides as with the lid it made a nice box to keep stuff in. A few years later I worked a 2.1 computer speaker amp and drivers in there (sadly I'd used the original speakers for a project), and added a Bluetooth receiver, an ipod touch and an additional aux cable - then mounted the whole thing on hair pin legs.
It is now a cute coffee table, chest and basic speaker system - but no where near as polished as yours!
