Acapella Audio Arts: The $650K Sphaeron Excalibur loudspeakers

Recorded in 24bit 96kHz at the Acapella showroom on May 13, 2019. We uploaded several of these videos. Please subscribe and check out our Acapella Sphaeron Excalibur playlist.

The Sphaeron Excalibur speakers weigh over 3000 lbs each, use a powered plasma (ION) massless tweeter and have four 18 inch woofers per speaker.

If you listen carefully, you will hear notes in the music you have never heard before. That is because the notes have been on the CD all along [which was uploaded to a music server for this demo] but no speaker has been able produce the notes correctly and distinctly before [having to do with the high efficiency of these speakers, the accommodating load they present to the amplifier, the ION Tweeter, etc].

And it is not just the notes, so much more emotion and excitement of the music is also audible for the first time.

Who knew that all our music had all this extra yummy goodness all along, but our speakers just kind of weren’t up to the task.

Associated gear (all extremely modest as these things go): Acapella “Audio One” music server, prototype of Acapella’s forthcoming dac/pre, new Acapella monoblock amplifiers.
