There is no substitute for the pure musical involvement and enjoyment to be experienced
when listening to the Epos Encore 50. This unique Epos Flagship loudspeaker was 3 years
in the making but there is no doubt the time taken to develop this exceptional
loudspeaker was well worth the wait.
Each and every part of the Epos Encore 50 was developed by Epos engineers to a
standard not previously achieved by the company. From the original design concept
through to the cabinet construction, speaker drive units, crossover and final voicing,
the Encore 50 stands superior in every way.
The speaker is tall and imposing yet exhibits elegance synonymous with Epos. Standing
1.2 metres high, it is deeper rather than wide and is supplied with a strong stylish painted
MDF plinth to support its 50 kg weight and spread its footprint for improved stability and
mechanical decoupling. Fully adjustable turned aluminium and steel spiked feet can raise
or lower the speaker to adjust or tilt the level. The cabinet itself is made from a composite
of birch-plywood and MDF which has been extensively strengthened internally using
plywood bracing within the mid-range and bass enclosures.
To ensure the lowest coloration, the cabinet and bracing have been optimised, following
accelerometer measurements and listening tests. Hand selected and book-matched real
wood veneer has been chosen give the most luxurious finish on an Epos speaker so far.
Separate bass, mid-range and crossover sections of the cabinet are hermetically sealed
and allow the crossover to be located in a convenient section at the bottom of the
cabinet, accessed via the large, ventilated terminal panel on the bottom rear with a letter
box opening in the plinth. All drive units are separately wired to the crossover section,
using custom Epos solid core wire.
The bass enclosure has a volume of 43 litres. Two 220 mm woofers are bass-reflex
loaded by one large diameter 90 mm port, positioned mid-way between the woofers and
flared at both ends to minimise port turbulence and harmonic distortion. The height and
spacing of the woofers has been chosen to minimise the ‘floor-bounce’ cancellation,
optimise bass output and ensure a smooth bass mid-range transition in room. The
mid-range unit is in its own, braced, 8 litre sealed box enclosure.
A custom made MDF plinth helps to extend the footprint of the speaker and decouple
mechanical vibrations from the cabinet. This makes the speaker more stable in a domestic
environment and improves low frequency performance. It also allows access to the
crossover adjustment patch-board. Adjustable metal feet allow the height and angle of
the speaker to be adjusted. This enables a custom skateboard to fit underneath so the
speaker can be transported on wheels to a different position and then carefully lowered
into place. This skateboard is supplied with the speakers.
The 2 x 220 mm woofers and 158 mm mid-range cones are made from a Kevlar/carbon
fibre/pulp mixture to combine high rigidity, with good inherent damping and feature
concave dust caps coupled tightly to the cone. Frequency responses of both woofer and
mid-range are inherently very smooth. They each incorporate a copper shorting ring in
the magnetic circuit to reduce and linearise inductance and therefore, reduce harmonic
and inter-modulation distortions at high sound pressure levels. The two woofer cones
couple acoustically at low frequencies and are port loaded for extremely high power
handling.
The tweeter is a specially developed version of the Epos Mi tweeter, with anodised
aluminium dome, Kapton voice coil former, braided lead-out wires and ferrofluid damping.
The centre pole is damped under the dome and vented into a contoured, felt-filled rear
chamber to damp the fundamental resonance frequency.
The crossover design of the Epos Encore 50 is revolutionary. It allows the user
unparalleled flexibility to compensate for individual room acoustics, without compromising
sound quality in any way. The tonal balance of the speaker may be easily changed by the
user to increase or decrease the tweeter and midrange output in 1.5dB steps, via an
aperture in the bottom of the speaker and plinth. The crossovers use high-grade
customised Epos polypropylene capacitors and non-polarised electrolytic capacitors,
which are bypassed with polypropylene capacitors on the mid-range and tweeter. It also
uses air-core inductors, a tapped autotransformer for adjusting the mid-range output and
laminated steel-core inductors. Metal oxide resistors are paralleled where necessary to
achieve high power rating and a custom heatsink is used to reduce the temperature.
The high sensitivity mid-range is attenuated by a tapped auto transformer, which doubles
as the high-pass crossover inductor. The tweeter network also has variable attenuation
via metal oxide resistors. The maximum sensitivity treble position bypasses all
attenuation. Passive components are mounted on a high quality, glass fibre PCB,
mechanically isolated from the cabinet.
The crossover PCB’s are designed to be completely, or partially, bypassed, to enable the
user to configure the speaker in passive or active mode. Epos will offer a custom DAC
with programmable digital crossover in the future to suit any make of amplification system.
The ongoing development for a future user upgrade to the Epos Encore 50 will represent
yet another great leap forward in Epos speaker design and will have music lovers giving
it a ‘standing ovation’ whilst applauding this exceptional speaker.
