Description
DALI OPTICON LCR
HAND-ASSEMBLED
The mounting of the drivers and the final tests and approvals on each and every speaker is also handled directly at our own assembly lines in our Danish factory.
DALI DRIVERS
All elements of the DALI drivers are designed, produced and manufactured in-house in DALI.
DALI MDF CABINETS
Keeping the manufacturing of the OPTICON series firmly in the hands of DALI we utilize our large and efficient woodworking facility in Denmark to handle everything from cutting out the Medium Density Fibreboard (MDF) cabinet to applying the vinyl.
SMC-TECHNOLOGY
In the OPTICON woofer magnet motor system, the pole piece is purely constructed of SMC. SMC’s unique ability to deliver a high magnetic conductivity and a very low electrical conductivity delivers all the wanted qualities of a really good speaker magnet without the traditional downsides.
PRODUCT DETAILS
Capable of operating as either an independent 2.0 system or as the centre channel in a larger set-up, the rotatable OPTICON LCR fires out its audacious audio via a 6½ inch low-loss Wood Fibre Woofer.
Added to this is our rotatable Hybrid Tweeter module and, finishing the ear-delighting effect, an advanced bass port configuration built into the back panel which uses the wall on which it is mounted to extend its acoustic properties. The result is truly astounding bass response despite a compact cabinet, without the need for an additional subwoofer in your sound set-up.
Whether you want one loudspeaker on your wall to handle all your audio needs or a centre loudspeaker to add that something extra to your surround system, the OPTICON LCR is your sound solution.
Legacy
The OPTICON LCR features the same low-loss Wood Fibre Woofer found in our flagship EPICON series, alongside our unique SMC (Soft Magnetic Compound) magnet motor system and a reworked version of our Hybrid Tweeter module also found in the RUBICON, all of which works together along with an individual bass reflex port for the woofer to produce audio exactly as the recording artist originally envisioned it.

BASSPORT
The OPTICON LCR relies on the bass reflex principle. The bass reflex port has been tuned to minimize distortion from the woofers, and to control the time response of the roll-off from the bass system.
On the OPTICON LCR, DALI has taken bass port design to a new level. Wanting to maximize inner cabinet volume we moved the bass port to back of the speaker. Using most of the back of the OPTICON LCR and the wall to control the bass port airflow the OPTICON LCR delivers bass at a level not expected from such a compact wall mounted speaker.
Timing is the absolute keyword when tuning bass ports. Correct timing without any unwanted interaction between the drivers and frequencies creates a holographic soundstage. Research clearly shows that speakers with superior time coherence deliver enhanced sonic realism.
SMC
Soft Magnetic Compound (SMC) is a coated magnet granule that can be shaped into any form that you would want. SMC has many advantages, and used in a speakers magnet motor system it result in a significant reduction of distortion from mechanical loss.
SMC’s unique ability to deliver a high magnetic conductivity and a very low electrical conductivity delivers all the wanted qualities of a really good speaker magnet without the traditional downsides. The result is a significant lowering of the colouration of the reproduced sound.
In the OPTICON LCR woofer magnet motor system the pole piece is purely constructed of SMC. This important addition to the ferrite based motor system is paramount to the audio performance of the OPTICON series.
HYBRID TWEETER
DALI has a long and well proven tradition for using a hybrid tweeter module. It is a combination of a dome tweeter working together with a ribbon tweeter for an amazing rendering of the high frequencies, and a dispersion of high frequency sounds that outperform all other tweeter technologies.
In our view, the Hybrid Tweeter Module is the perfect high frequency solution. Both the soft dome and the ribbon tweeter are free of artefacts, e.g. resonances and high Q peaks within their working range.
The Hybrid Tweeter Module features an extremely smooth and wide horizontal dispersion – one of our sound design trademarks. Even the detailing of the faceplate of the tweeter module is designed for optimal horizontal dispersion.
The characteristics of the Soft Dome Tweeter is low resonance frequency, high power handling, and exceptional headroom for high sound pressure levels and extreme excursions. It is rolled in carefully around 2.0 – 2.5 kHz, depending on the model. And the dome is allowed to operate up to its high frequency limit well beyond 20 kHz without being rolled off in the crossover.
Incorporating an ultra-thin magnetic fluid for cooling, the fluid has a very high flux saturation point for greater power handling. This also means superb control of coil movement – even at very high sound pressure levels.
The ribbon tweeter features a broad frequency band and superb dispersion in the higher frequencies. Gently rolled in above 10 kHz, the ribbon reaches full contribution from 14 kHz to well beyond 30 kHz, far above the audible range.
Equipped with a rear chamber fitted with rigid bracing, the ribbon is shielded from the disruptive influence of the woofers. The DALI ribbon tweeter is a true master in horizontal distribution of high frequencies, and a superb partner for the soft dome tweeter’s unique ability to reproduce frequencies from 2 kHz upwards.
WOOFER
The woofer for the OPTICON LCR is designed with a strong focus on DALI sound principles of low-loss, low distortion and low colouration of the reproduced sound. The ideal speaker plays just what the amplifier intented, with nothing added and nothing subtracted.
To meet these ideals every part in the OPTICON woofer is carefully chosen for its low-loss abilities. The cone is made from a pulp mix of paper and wood fibre that ensures very low surface resonance and gives the cones their distinctive colour. The cone terminates in a rubber surround that is chosen for its soft and very flexible properties. This gives the cone free movement with very low dampening effect, and leaves control of the cone movement to the WOOFER magnet motor. The rubber surround is attached to an aluminium chassis that, due to the properties of aluminium, offers almost no interference to the magnetic field surrounding the magnet motor.
The magnet motor itself consists of a large ferrite magnet that surrounds a pole piece made entirely of the unique material SMC. The pole piece and the ferrite magnet are secured between two soft iron plates. This forms a close to optimum environment for the 2 layer voice coil to work within. The voice coil is therefore able to transform the signals from the amplifier in to an undistorted, uncoloured and very well timed reproduction of the original signal, leaving the listener with a close to live experience.
CABINET
Keeping the manufacturing of the OPTICON series firmly in the hands of DALI we utilize our large and efficient woodworking facility in Denmark to handle everything from cutting out the Medium Density Fibre board (MDF) cabinet to applying the vinyl. The mounting of the drivers and the final tests and approvals on each and every speaker is also handled directly at our own assembly lines in our Danish factory.
The OPTICON LCR’s front baffle form a rigid base for the drivers, which are screw-mounted directly into the 25 mm thick MDF. To ensure the best possible hold on the woofer and thereby integration with the cabinet, the 5 screw holes are placed along the arms of the woofer chassis. The tweeter module is held securely in place with 6 screws to eliminate vibrations and resonance. A rubber gasket is placed between the woofer and the milled out rim to ensure a 100% airtight fixture.
The baffle sports a black or white high-gloss finish, for a more exclusive look and feel. The slim-line design of the front baffle contributes to the stereo perspective. And the ‘clean’ surface is not only pleasing to the eye; it reduces diffractions to an absolute minimum.
