Our new Showplace is now open in Broomfield, Colorado. Call for an appointment. In the last few months we have taken Vandersteen Treo's and the Sonus Faber Olympica 3's in trade towards these as they smoked them both when  the owners heard them at our Broomfield facility and it their homes.

The new EP2.7  was our best speaker and an big upgrade over our highly respected EP2.3 (formerly CS2.3 MK2) that received the superb review in the January 2015 The Absolute Sound. Upgrades are a dramatically better Polyester tweeter, our $600.00 Special Edition crossover and the beautiful $1200.00 automotive Tri-coat black finish. The included $600.00 Special Edition crossovers have custom Emerald Physics caps, upgraded resistors, diodes and coils. These upgrades are the last bit of transparency and extra detail that the EP2.3 omits and makes them competitive with the best electrostats and $25-50k box speakers offer. They keep the amazing soundstaging, imaging and dynamics of the EP2.3 as well as its superb tonal balance.

See the EP2.7 video from The Newport Beach show at:


The EP2.7  is a more refined version of the EP2.3 with better resolution, detail & micro dynamics.
With its new state of the art 12" point source professional midrange and Emerald Physics Polyester tweeter drive system, the EP2.7 is a true higher resolution step over the original CS2.3. The increased resolution, speed and inner detail of the EP2.7’s is exceptional. The speaker sounds more like an electrostatic in these areas. Imagine a high resolution planar with superb bass, dynamics and 97Db efficiency!

Our Controlled Directivity design removes the listening room and allows the speakers to work in almost all rooms.

The EP2.7 is a 3-way, 4 driver, bi-amplified, dipole speaker design. It can be single amped, bi-amped or tri-amped. Cutting edge sonic performance establishes a new level of realism and dimensionality at its price. Our proprietary Aperture Bass Propagation Technology is used for both custom Emerald Physics 15" dipole woofers, improving low frequency power and linearity. DSP equalization and active crossover functions are provided by the included Special Edition passive 2 way crossovers and the Emerald Physics DSP2.4 digital electronic crossover between the woofers and midrange/tweeters. They are even better tri-amped. We have complete Superb speaker/amp/preamp/DAC with room correction packages from $7,800.00.

The EP2.7 is sold Internet Direct with no dealer profits and will embarrass most $20k$-40k speakers sold thru retailers.
