Does a 4x12 with ONLY ONE Speaker STILL sound like a 4x12?

In this video I play a 4x12 speaker cabinet and then I disconnect 3 out of 4 speakers to see if it still sounds like a 4x12. I'm using a 1971 Marshall 1960B with 1973 G12M25 75Hz Pulsonic Greenbacks in it. These speakers are really expensive so if it's enough to get one of those and a 4x12 box for recording it would be good news to many. Furthermore the classic 4x12 tone is a bit bassy and sometimes a bit muddy why this arrangement could be a good recording trick. Check out the video and let me know what you think!
