I prefer a massive, natural acoustic bass, and its cohort in bass amplitude, the Hutchins Bass violin basses, of the New Violin Family Octet of violins. Of the two in the video still, the smaller is the profile of a normal concert bass. The one on the right is massively larger, and ranges down to 32hz, natural acoustic response.
These are by Dr. Carleen Hutchins, as part of The Hutchins Consort performing octet, the only set of them being played; all others are in private collections (british royalty has a set), and, museums, as show pieces.
My pet project since their inception, apprx. 2001, The Hutchins Consort New Violin Family Octet, or THC for short.
The recording - best mics possible:
Royer dynamic stereo ribbon on center
Earthworks QTC-1 omni pair on flanks (if memory serves me well, flat response to 5hz)
The hall?!?
Neurosciences Institute Auditorium - La Jolla, Ca
designed to study the effects of music and sound on the human mind. Thought to be one of the finest small concert halls in the world; -300 seats. You sit within the bandshell, and, phenomenal sound throughout the hall. It is a musically friendly anechoic chamber.
Summertime - Gershwin by THC
And, then there is this one from a live pipe organ recording:

(a hint,... look to the blob on the left)
