The OPTICON MK2 speaker range majors on clear, undistorted, enjoyable and coherent audio - perfectly complementing music, radio, streaming, TV or movie sources. The speaker series caters to every requirement - offering a speaker for every room and every occasion. Comprising six models ranging from a compact on-wall speaker to a towering floorstander.
The new OPTICON MK2 hybrid tweeter marries the CALLISTO-derived 29 mm soft dome with a custom 17 x 45 mm ribbon - mounted on a cast aluminium faceplate that incorporates dispersion control detailing. This combination offers the clarity, speed and dynamics of a dome tweeter, with the very high frequency detail and smooth finesse of a ribbon tweeter.
The newly introduced OPTICON MK2 Dual Flare technique brings port design into the realm of aerodynamics - with exit and entry flares carefully designed to minimise turbulence. Dual Flare enables OPTICON MK2 reflex ports to remain laminar and work effectively to reinforce low frequency performance to a significantly higher volume level than would otherwise be possible.
Speakers used and enjoyed in pairs should also be built as pairs! Our manufacturing process is designed to ensure that stereo pairs of speakers are built and tested sequentially by a single manufacturing technician, using components taken in the same order from the same batch. It’s a process that helps ensure ultimate visual and acoustic pair matching.
The SMC used in OPTICON MK2's magnet motor system has very high magnetic permeability and very low electrical conductivity. It works primarily by minimising eddy currents in the magnet system pole piece. This improves flux linearity, reducing the magnetic hysteresis. Resulting in a significant reduction of electro-acoustic distortion.
An important element of the OPTICON MK2 range is that the production remains fully Danish - as with the original OPTICON series. The entire lineup is manufactured at our own factory from components either produced in-house, or mainly sourced from the best local specialist-manufacturers. We are therefore proud to say that the OPTICON MK2 series is designed, developed and manufactured in Denmark.
The OPTICON VOKAL MK2 is specifically voiced to play the centre channel role, but at the same time it displays all the characteristic qualities that enable it to dovetail perfectly in a full OPTICON MK2 audio visual system.
The centre channel offers a level of performance unavailable from any other OPTICON model. It combines immense low frequency bandwidth, volume potential and dynamic accuracy with the extraordinary detail and clarity that arises from the use of a dedicated midrange driver. High frequencies from the hybrid tweeter are explicitly detailed and informative yet simultaneously smooth and endlessly listenable.
The enclosure dimensions and proportions are specifically configured to enable its installation in audio-visual furniture units, and its front facing reflex ports mean that even fully enclosed mounting is feasible.
This makes it perfect for placement up against a wall underneath the TV or projector screen or even hidden away in a HiFi furniture when not in use, which it also has been specifically designed for - a nice feature for aesthetically minded home theatre owners.
The OPTICON VOKAL MK2 is the perfect partner for any speaker in the OPTICON MK2 series, with the same level of detail and coherence – but also powerful enough to be used even with the OPTICON 8 MK2.
The manufacture of the entire series remains fully Danish - as with the MK1 series. Built at our factory in Denmark; from components produced in-house or sourced from the best specialist manufacturers locally and further afield.
The VOKAL MK2 is available in Satin Black, Satin White and Tobacco Oak.
The
OPTICON VOKAL MK2 driver magnet system consists of a large ferrite ring
magnet surrounding a pole piece manufactured entirely of the unique
DALI SMC material. The pole piece and the ferrite magnet are secured
between soft iron front and back plates to create the appropriate
magnetic field for the voice-coil.
DALI SMC (Soft Magnetic
Compound) is a coated magnet granular material that can be formed to
almost any desired shape and has many advantages used in driver magnet
systems. SMC’s unusual combination of very high magnetic permeability
and very low electrical conductivity is exactly what is required for
driver magnet systems and results in a significant reduction of
electro-acoustic distortion.
SMC works primarily by minimising
eddy currents in the magnet system pole piece, which reduces distortion.
SMC also improves flux linearity within the magnet system - reducing
magnetic hysteresis. All of these SMC benefits together produce a
significant subjective reduction of low-level detail masking and
colouration.
SOFT DOME
The new unique
light-weight 29 mm soft dome tweeter is derived from CALLISTO C and
offers significant advances over the tweeters used in the MK1 series.
The relatively small increase in diameter over the previous 28 mm
tweeter results in a significant increase in dome radiating area. This
means lower distortion, higher power handling, and an ability to operate
at lower frequencies.
The use of the same 29 mm soft dome
tweeter across all six OPTICON MK2 models results in consistency of
tonal character and provides consistency of dispersion characteristics.
The MK2 soft dome tweeter enables crossover frequencies as low as 2kHz
to be safely employed with no risk of distortion or power handling
limitations.
HYBRID TWEETER
The OPTICON VOKAL MK2 employs a
new hybrid tweeter design that marries the 29 mm soft dome tweeter with a
custom 17 x 45 mm ribbon. Both mounted on a cast aluminium faceplate,
which incorporates dispersion control detailing.
The ribbon
element begins to contribute from 10kHz upwards; just as the response of
the soft dome element is beginning slowly to fall away and become more
directional. The ribbon element both extends the system frequency
response towards 30kHz and contributes to keep high frequency horizontal
dispersion wider than would otherwise be the case.
The new
hybrid tweeter offers the best of both worlds – the clarity, speed and
dynamics of a dome tweeter, with the very high frequency detail and
smooth finesse of a ribbon tweeter.
The placement of the hybrid
tweeter drivers between the two widely spaced bass drivers is done
firstly in order to position the high frequency drivers near typical
seated ear height. Secondly to take advantage of the smoother low
frequency room response that results from spaced bass drivers.
The
6½” wood fibre driver handles the low frequencies and the midrange -
both build around DALI's patented SMC magnet motor system.
Every
component of the driver is carefully designed for its positive
contribution towards ideal performance. The diaphragms are made from a
mix of paper and wood fibre that ensures minimal break-up resonance and
gives the diaphragms their distinctive DALI trademark colour. They are
terminated by rubber surrounds chosen for their soft and very flexible
mechanical properties that enable free movement with minimal low
frequency damping.
The driver chassis for each driver is
manufactured in die-cast aluminium that provides extremely high rigidity
and low resonance along with minimal extraneous influence on the
internal magnet system. The mechanical design of the chassis is
specifically engineered to provide minimal impedance to airflow while at
the same time enabling extremely tight mechanical bonding with the
speaker enclosures.
The drivers were designed with a consistent
focus on the DALI audio principles of low-loss, low distortion and low
colouration. The ideal driver plays only what the amplifier requires,
with nothing added and nothing subtracted, and at DALI we strive to
design and manufacture drivers that approach the ideal as closely as
possible.
The enclosure of the OPTICON VOKAL MK2
is designed to optimise rigidity and minimise panel resonance. The 25mm
thick front baffle provides massively rigid foundations for the drivers.
The manufacturing of the OPTICON MK2 series has been retained
firmly at the DALI factory in Denmark. Our in-house woodworking facility
handles everything from cutting and routing the MDF panels to the
driver and crossover installation. The final test and quality approval
on each and every speaker is also handled on our own assembly lines.
The
reflex ports employed in the centre speaker is not Dual Flare design,
however the ports are no less carefully considered. The OPTICON VOKAL
MK2 employs twin, forward facing letterbox style reflex ports configured
to enable the system to be enclosed in furniture units. Not only does
its enclosure format not provide enough space for Dual Flare, port
flaring is less critical on a system designed primarily for voice
reproduction.
