ILLUMINATION by Mosaic Acoustics are Floor Standing Two-Way Loudspeaker with Reference external crossover. Built and designed by famed Dale Pitcher.
We are marking it below dealer price for a quick sale. 

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. Dale said that he never felt the need for subwoofer.

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


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.
