ILLUMINATION
by Mosaic Acoustics
are Floor
Standing Two-Way Loudspeaker with Reference external crossover. Built and designed by famed Dale Pitcher.

These are the most sophisticated speakers I have had in my system. When people bring their own music and listen to it through these speakers, they remark how they never heard the level of detail on that track before.

These are reference class two way speakers that may require subwoofers for some people's taste or for larger rooms.

We are selling them as they are very heavy and we cannot move them to allow audition for other speakers in optimal location in our listening room. The speakers are priced aggressively for quick sale.

Speakers come professionally packed in wooden crates custom built to fit like a glove.

At Axpona 2015, these speakers were part of the five significant exhibits as reported by The Absolute Sound. "This system produced an engrossingly delicate and intricately layered soundstage, with extended, effortless, and airy high frequencies. Voices were vibrantly lifelike, thanks in part the Allnic’s exquisite portrayal of microdynamics, reproducing all tracks with a delightful immediacy and intimacy."

Product Description

The
Illumination is a hybrid horn/transmission-line design, which includes both an adjustable
pedestal for vibration termination and a Vibration Isolation Platform. The
current reference speaker by the designer Dale Pitcher.



Product Highlights: According to Dale, he does not know of another speaker that has all these technologies incorporated into a single design.

·      Mass Quartz Loading

·      Vibrational Load Termination

·      Isolated Silent Mechanical
Grounding

·      Cast External Filter
Networks

Specification

Efficiency
of 92.6 dB. 

Frequency
response of 55kHz to 35Hz.

1)     
The Pedestal:  The Illumination rests on an internally-cast platform
assembly with 5 –  1” diameter Brass thru-assemblies.  Interfaced
internally with each of these shafts are mechanical loads for the termination
of vibrational energy. A pocket at the rear of the pedestal allows for the
inset of the external filter housing below the speaker.

The 30 pounds of reactive-mass on the interior the pedestal provides for bass
isolation from the floor and considerable energy projection into the listening
environment.

2)     
The External Filter Assembly: The Filter topology of the Illumination is a 1st order
Butterworth.  The external housing is cast in Quartz aggregate and
contains the 3 terminal blocks and the electrical componentry.  It is set
on 3 Brass feet.  The capacitor is a proprietary design assembled by
Mosaic Acoustics.  The non-conventional topology allows for extremely fast
and symmetrical rise and settling times without the overhang of internal
electrical energy storage.

3)     
The Bass Housing:  The Bass Housing is cast from a mineral filled
“plasticized” cement.  The casting defines the acoustical paths. The
acoustical load is an integrated hybrid design:  Laminar-Flow Transmission
Line, Exponential Horn and Aperiodic topologies are used in both parallel and
series configurations throughout the acoustical load.  All
internal damping is with long hair wool and acoustical wool felt. 
Exterior wall construction is a seven layer constrained-layer damping
configuration, culminating in .5” thick granite on the exterior surface.

4)     
The Vibration Isolation Platform: This provides for two primary functions –
isolation of the tweeter housing from modulated bass cabinet vibrations
(isolated silent mechanical ground) and a mechanical load termination to
dissipate any vibration from the tweeter housing (exclusion of Doppler issues).

5)     
The Tweeter Housing:   The Tweeter Housing features a 1.125” silk
dome tweeter which couples into an internal quartz aggregate load.

 

Design
Overview:      

1)     
ACOUSTICAL PROPAGATION:  The Illumination loudspeaker is configured to
emulate a point-source.  Transducers are vertically aligned.  A set
of charts and a protractor system is provided with the speaker system. 
The listening distance and ear height at the listening position correspond to
chart information which gives transducer housing offsets.  The protractor
system allows the user to easily position the lateral displacement of the
tweeter housing.  With this alignment, the arrival times of each
transducer at the ear is the same.

 

2)     
REAR WAVE LOAD TERMINATION:  Several key areas are addressed by the design
topology and the execution of the rear-wave loading in the cast bass
cabinet.  These include:  internal resonant modes, turbulence, linear
load progression and linear (face and load) throat air-flow patterns.

 

The Bass
Cabinet housing for the Illumination was designed by Dale Pitcher over a three-year
period.  This singular internal acoustical load configuration is the
subject of several patents in process.

 

The
Illumination Bass Cabinet pioneers a new direction in dynamic transducer
housings. It combines Laminar-Flow Transmission Line, Exponential Horn and
Aperiodic Load topologies in both parallel and series configurations throughout
the progression of the acoustical load.  Great effort has been placed in
eliminating all internal turbulence patterns and resonances within the
enclosure, and providing for a completely linear load progression.  The
result is bass energy freed from the constraints of compression, resonances and
time overhangs – bass energy capable of startling dynamics on micro and macro
levels.

 

3)     
SIGNAL PATH INTEGRITY:  Considerable attention is paid to maintaining the
integrity of the electrical signal path to the transducers.  All
connections are made with modified Cardas CPBP Binding Posts. Filter capacitors
are made in-house and have extremely fast rise and settling times. The internal
wiring harness is Mosaic Sigma Speaker Cable (which retails at $2000 for the 8’
pair).  All signal path componentry is deep-cycle Cryogenically treated.

 

4)     
VIBRATIONAL CONSIDERATIONS / MECHANICAL ENERGY LOAD TERMINATION:  The
Illumination addresses the issues of spurious vibrations more than any other
dynamic loudspeaker.  Unaddressed vibration issues re-emerge as a
modulated haze.  The Illumination suspends music on a totally silent
background that is alive with unmodulated ambient information.
