Epos Acoustics K1 Bookshelf Speakers (Satin Black, 1 Pair)
The K-1 is a stylish and sonically impressive loudspeaker, built to a very high standard!
The all new K-Series marks the beginning of a new era for Epos. Designed by Luke
Creek, the K1 stand-mount loudspeaker is the starting point in this new range.
The K series features an unusual front firing slot port, rear mounted drivers
and painted cabinet finishes. The K-Series is not only sleek and stylish, it
also has a clever trick hidden up its sleeve.
"This two-way compact embodies the balues every audiophile on a budget is seeking with a sonic character that's open, dynamically engaging, and tonally the better part of neutral. Its spectral balance is lighter overall as befits its pint-sized enclosure, but it no lightweight sonically. The K1 has superior balance and poise on small-to-medium-scale music, but can also rise - within limits - to the challenge of full-range symphonic pieces... the K1's an amazingly potent little speaker..." - The Absolute Sound, January 2014
Out of the box the K-Series is a stylish and sonically impressive passive
loudspeaker, built to a very high standard. Now for the trick; designed into the
K-Series is a latent upgrade path that allows it to be converted from a passive
to a sophisticated ‘active digital’ product, using an optional Active-K module.
Active-K allows the K1 to be at the heart of a 21st century ‘Hi-Resolution’
The K-Series is much more than just another box loudspeaker, it paves the way to
the future of Hi-Fi! The all new K-Series painted MDF cabinet design includes
some very clever internal bracing to minimize cabinet coloration. The K-Series
sees the introduction of new reflex front firing slot port technology, designed
for two special reasons.
Firstly, it allows high volumes of air to pass without any nasty audible
chuffing noises, unlike most conventional round tube ports. Secondly, the slot
port has enabled Epos to improve the low frequency response performance from
such a relatively small driver area. One of the key design factors included in
the K-Series is the ability to convert to an ‘active digital’ speaker. The rear
panel and passive crossover are designed to be removed and replaced with the
The K-Series is available in two elegant finishes: Satin White or Black. Both
finish options offer a wonderfully luxurious look and feel to these
loudspeakers. For those times when the attractive front needs to be protected or
hidden, an optional magnetic grille can be easily fitted. Just place it close to
the front and it will automatically snap-into place, protecting the delicate
drivers from little fingers or paws.
Using virtual performance CAD design simulation tools, Epos has achieved very
high technical performance and a clean, open, yet smooth sound quality from this
The tweeter has a low resonant frequency, high sensitivity and extended high
frequency response. With a 25mm fabric-dome, short horn, high-temperature
Ferro-fluid cooled voice-coil and neodymium magnet, it is capable of playing at
high output levels for extended periods without degradation to its sound
The Epos K1 mid-bass driver produces an even frequency response and smooth
This mid-bass driver has a high-quality polypropylene cone and a bullet-shaped
dust cap. These components form a stiff, yet pliable, well-damped structure
which retains its shape even under high power loading.
The K1 mid-bass driver also benefits from a bucking-magnet system, ensuring all
the magnetic force is concentrated around the voice-coil, allowing for low
distortion and high efficiency.
In true Epos tradition; the K series has reverted to a more simplistic passive
crossover topology, for which the brand is synonymous. A first order crossover
is used to allow the Epos tweeter to have a wide dynamic range with super low
distortion. The mid-bass crossover uses a 2nd order filter ensuring the K1 is an
easy load for any amplifier.
Coming soon...The Active-K module sets this range of loudspeakers apart from
the rest of the field. Either from new or as an upgrade path, the Active-K
module replaces the rear panel of the K1 providing you with a number of
Built-in to the Active-K module is a Creek-designed power amplifier. A high
quality multi-input DAC, Asynchronous USB and Bluetooth receiver provide your
digital inputs. The Active-K will also include an analogue input for those who
wish to use a turntable or other form of analogue source.
The Active-K replaces the lossy passive crossover with an active version,
allowing superior driver integration and even wider dynamic range, thanks to the
use of EQ (equalization) below the port resonance.
The Active-K module allows inputs to be selected and the volume adjusted via a
handheld remote handset. With intuitive control defaults, the Active-K is easy
to operate despite not having a display.
