Pure Analog Controlled Directivity Open Baffle Loudspeaker

At the introduction at the Newport Beach Show Robert Harley of The Absolute Sound said:

Perhaps the best overall value at the show was the Emerald Physics KCII open-baffle loudspeaker system ($2499) driven by the company’s EP100.2SE hybrid power amplifier. The whole system was priced at just under $6k at retail, but offered at $3799. This system put many five-figure systems to shame.

At the same show Paul Seydor from TAS said:
Best Sound (for the money):
Emerald Physics KCII speaker system ($2495/pr.) driven by Emerald’s EP100.2SE amplifier and Anti-Mode’s Dual 2.0 as preamp playing CDs from a modest Marantz player. This demo featured among the most involving overall sound that I heard at the show.


In the first review in Audiophilia they summed with:

"The trickle down technology from the top Emeralds like the EP-2.8s to the new KCII is very effective. You'll get both very sweet and dynamic sound, transparency, a beautifully balanced midrange and a solid low end all for a very reasonable price. Very highly recommended."

"It is with great pleasure that we award the Audiophilia Star Component Award to the Emerald Physics KC II Open Baffle Speaker. Congratulations!  Ed "

Part Time Audiophile said from the RMAF show:

"I should note that the package deal that Walter had set up for this room — $6,995 for the KCII speakers, amp, DAC and subs — was one of the very best deals going at RMAF this year. With a Comet riding this high and this hard in this room (and the fact that all of this could be had at this price), made for an experience that was not only astonishing, it was a sure sign of the apocalypse.  Nice work, gents."

The new KC II is here! The KC II is the first under $2500.00 open baffle Emerald Physics speaker that runs with no DSP and can be run with a single amp. We believe it is a breakthrough in a speaker in this price range. With its new Emerald Physics designed 8” “Godzilla” point source professional driver system and Aperture bass loading, the KC II is a true 4 driver 3-way open baffle design. Open baffle presents music without the box colorations of typical speakers. Our dipole bass/midrange presents a huge sonic soundstage that offers superb imaging with our point source midrange/tweeter design. Cutting edge sonic performance establishes a new level of realism and at anywhere near its $2495.00 Internet Direct retail price.

        Single Amp drive - Does not require bi-amplification, although it can be bi-amped or tri-amped for even better performance.
And they are amazing with our DSP electronic crossover and a powered subwoofer
