Thank you, and happy listening!

Mirus Coaxial Systems

Your Mirus system contains speaker drivers and a tweeter passive crossover network that were developed and assembled with a signicant eort in research and development, materials science engineering, an exhaustive level of sampling and prototyping, real-world testing, and obsessive attention to detail. The specications and parameters of your Mirus coaxial system is detailed on these pages.

Midbass Attributes

Mirus M4, M5, M6, M57, & M69

Frame

Stamped and powder-coated steel. The basket is a high-quality stamped steel design, which plays a critical role in aligning the voice coil in the magnetic circuit. The frames are proprietarily tooled by Hybrid Audio to allow for the inverted mounting of the surround, discussed in detail below. The stamped steel frame provides adequate clamping force in relation to its mass, and ensures that the voice coil remains centered in the former.

Cone

Pressed paper with water proof treatment. It is widely acknowledged that pressed paper cones are the best marriage of lightness, stiness, and ability of the cone to damp unwanted cone and edge modes and resonances (read: distortion). The paper cone, known for its excellent sonic attributes, is water proof, thanks to a polymer developed exclusive and proprietarily by Hybrid Audio Technologies. The treatment does not change the look and parameters of the driver like old-fashioned “glossy” polymers which added an appreciable amount of moving mass and signicantly colored the sound. No, the Mirus cones look like any “normal” paper cone, but in reality are likely the only high-performance water proof paper cone car audio speaker systems on the market. The treatment protects the cone from periodic drips (such as inside

a door panel), as well as accidental splashes to the front of the cone. On the hybrid-audio.com website, we have hosted a video of an actual water-proof demonstration where we pour two liters of water over an Imagine coaxial (sibling to the Mirus coaxial that uses the same cone topology), and then connect it to a musical source. That video may be viewed at: http://hybrid-audio.com/imagine/

Tweeter Pole Piece

Cast ABS plastic. The tweeter pole piece is ABS and eectively places the tweeter forward of the cone, centered, for optimal operation. The pole piece contains a unique swiveling feature to allow for aiming of the tweeter.

Surround

Inverted high-loss rubber surround. The inverted high-loss rubber surround (in concert with the spider, detailed below), helps to provide the compliance and “restorative force” needed for the Mirus drivers to play eectively into the lower coaxials, and perhaps even upper subbass frequencies (depending on in-car cabin gain and other factors). You’ll also know a Hybrid Audio midrange and coaxials design by its inverted surround; this design feature allows for the use of a smaller height grille, better clearance with OEM panels, and more exibility in mounting options. The inverted surround is a Hybrid Audio exclusive in automobile loudspeakers.

Spider

Phenolic fabric and tinned tinsel leads. The spider is the brownish/yellow corrugated (rippled) fabric that attaches the cone and voice coil. The spider for the Mirus designs was the subject of a considerable amount of our research and development. The spider is a phenolic symmetrically-rolled fabric which provides excellent restorative force during excursion. The tinsel leads are connected to real epoxy PCB, not imsy cardboard, unheard of in the price range of Mirus.

Voice Coil and Motor System

The voice coil used in the Mirus coaxials is a 2-layer aluminized copper wire coils on a round former. An “overhung” voice coil was selected to improve sensitivity while still keeping distortion to a minimum.

Tweeter Attributes

Tweeter Passive Crossover

Coaxial Systems

Mirus M1

Dome

Small diameter impregnated silk textile dome with high-loss rubber suspension. The M1 has an impregnated ne cloth silk dome diaphragm for a linear, smooth sound, with a high-loss rubber suspension to damp edge modes and resonances. The dome is of extremely low mass and is much less susceptible to mechanical deformation than other designs, and yet yields a smooth response over the extent of its range. At Hybrid Audio Technologies, we feel larger diaphragm tweeters sound heavy and unremarkable, lack detail in the upper treble frequencies, have undesirable polar response, and are dicult to install. Additionally, we nd metal dome tweeters to be harsh, brittle, and sound unrealistic. As a small diameter, soft-dome tweeter, the M1 is the antithesis of large diaphragm and metal-dome tweeters, for the eective and convincing reproduction of treble frequencies.

Low-Tolerance Mylar Capacitor. The tweeter’s protection circuit and crossover lter is a very high-quality, low-tolerance Mylar capacitor that has been axed to the coaxials frame. An outboard crossover “box” is not included for empirical reasons, explained in this portable document format download provided for the Imagine series, a similar crossover topology.

Thiele/Small Parameter Discussion for Mirus Midbass Speakers

The mechanical and electrical parameters of the Mirus coaxials are amenable to a variety of dierent installations and speaker locations. The high Qms (Q factor of mechanical system) and Qts (Q factor of total system), coupled with the driver’s Fs (resonance frequency) allow it to be used in an “innite bae” conguration. In more practical terms, install the Mirus coaxials such that the front and back waves don’t “meet” (as

Voice Coil and Motor System

20mm complimentary design. The motor assembly is “conventional dynamic”, with a compact neodymium magnet structure to ensure a small footprint size and shallow depth. A perforated grille protects the dome. The voice coil is ferrouid cooled and damped.

detailed in later in the Basic System Installation), including in a door or kick panel, or in the case of a motorcycle, in the fairing (using only the airspace behind the speaker as a pseudo enclosure), with no need for a real enclosure or “box.”
