    I remember in the early 70s there was a make of speaker (can't remember the name - JBL?) where the actual speaker was mounted near the top, but was then pointed down to a flared 'horn shaped' cavity where the sound was transformed, perhaps even amplified non-electronically, to be louder and deeper. Used by rock bands and DJs.

Using this very ordinary speaker systems can produce high quality results. I first saw this demonstrated when I was a student where students had to present a project as part of their course work to their fellow students and academics.
