Ending the myth that single driver cannot do low extension

Lots of meandering thoughts around loudspeakers, especially single drivers... how they compare to multi drivers... on what is really full range.. and how even multi drivers fail at that as well....
And getting to the point that these fun little single drivers can provide astonishing deep bass of heart and visceral warming quality. Timpani, church organ, cello, full orchestra is so lovely with this alley cat driver. It energizes the room with my 2W 807 Darling amp.... I was listening to a Hania Rani studio concert recording with two pianos and a keyboard synth with super deep tones... and it kicked the butt in the low end of my Sennheiser so badly it hurts. (As the adage says folks listen to HP for bass extension... now this single driver gets me quite a bit next level LF experience to a HP!!!!)
