Pure Sound. Nothing But.

CMMD®

CMMD – Ceramic Metal Matrix Diaphragms sandwich an aluminum driver between ceramic layers, the ultimate construction for accuracy. Ultra rigidity means no unwanted coloration, while lightweight cones pick up subtle detail.

Not just Loud. Accurate.

MMD®

MMD – Metal Matrix Diaphragms use advanced materials to improve accuracy. Both sides of an aluminum core are anodized for rigidity and speed, resulting in pure, truthful sound. MMDs derive from Infinity’s patented CMMD technology.

Waveguide Tweeters

Waveguide Tweeters improve on-and-off-axis high-frequency response for great imaging, presence and sound throughout an expanded listening area.

Ceramic Metal Matrix Diaphrams

CMMD®

Loudspeaker systems aim to be acoustically neutral, converting electrical signals into exact sonic equivalents with no audible internal resonance, no sound added or subtracted. Infinity engineers collaborated with metallurgy specialists to find the right combination of materials, stiff enough to provide uniform contact with the air, lightweight enough to react quickly to musical impulses.

Our engineers sandwiched an aluminum driver between layers of alumina, a ceramic compound. The result is Infinity’s legendary Ceramic Metal Matrix Diaphragms, CMMDs. Sound travels nearly twice as fast through these cones, and the sandwich construction has better damping, to remove unwanted resonance, CMMDs are 225 times stiffer than standard diaphragms, so there’s not a touch of unwanted coloration. And the lighter weight lets them pick up subtle musical details. It’s audio so extraordinarily real, only live sounds better.

Not just Loud. Accurate.

MMD®

Infinity MMDs are based on our patented CMMD technology, with high-end performance and nearly identical benefits at a lower price. MMDs consist of a three-layer sandwich structure, with a stiff core of pure aluminum, anodized on both sides. The result is a perfect balance of stability and weight.

The exceptionally rigid material pushes unwanted resonances outside of the transmission range, guaranteeing maximum performance and an even frequency pattern without distortions. You get fast response and clean, accurate reproduction of voices and instruments, even at higher volume – an experience that approaches live sound.

Expand the Sonic Sweet Spot

Wave Guide Tweeters

Typically, rooms have a sweet spot where sound from all speakers is equally focused for ideal listening. But most seats in the room are outside the sweet spot, or off-axis. And as sound bounces off walls, ceiling and floor, it reaches listeners at different moments and from different directions, which can further muddy the clarity. Infinity speakers use a proprietary waveguide around the tweeter to ensure a wide dispersion of the high frequencies.

Fantastic Bottom End.

Slipstream Tuned Parts

Slipstream™ Tuned PORTS use patented technology to improve bass performance. Curved, flared edges minimize turbulence, reducing port noise and delivering precise, powerful base.

Great Bass in a Small Package

Passive Radiators

Passive Radiators increase a speaker’s low frequency response to give a smaller audio system the deep, smooth performance of a much larger system. Get big, clear bass tones with a smaller woofer.

Digital Amplification

With high performance and low power consumption, digital amps are poised to replace traditional analogs. They use less heat, less space, and pick up less noise.

Fantastic Bottom End.

Slipstream Tuned Parts

Not all ports are created equal. They can be noisy if the music is too loud. And if not tuned correctly, they can do more harm than good to your car’s bass performance. Infinity engineers developed Slipstream proprietary port technology to reduce noise and improve definition.

The Slipstream™ port is round and flared to eliminate turbulence and put an end to wooshing and chuffing at high volume. There’s less chance of damaging the driver. And you’ll hear and feel every note of deep, booming bass.

Passive Radiators

A lot of air needs to be moved to produce audible low frequency sound, so you traditionally needed a large woofer to get clear, booming bass. A passive radiator speaker can increase the bass response to make smaller speakers perform like larger speakers.

A passive radiator is simply a speaker without the electronic structure – just the cone, suspension and frame. When mounted to a driving speaker, air pressure in the passive radiator causes the back and forth movement that create sound frequencies. Passive radiators allow woofers to produce deeper tones, absorbing energy from the drive woofer and dampening the drive woofer’s motion for smoother sound with less strain, and using less space.

Digital Amplification

Digital amplifiers can pick up fine detail, they’re immune to unwanted noise, highly efficient, flexible, and allow quick changes. The digital amplifier converts the input signal to a sequence of digital pulses, or a signal waveform, then amplifies the pulses and converts them to the equivalent analog signal to be fed to the speaker, essentially creating an exact reproduction of the source sound.

The audio signal stays in digital form virtually all the way to the speaker, so it doesn’t pick up electrical noise and there’s no deterioration. With these advantages over traditional analog circuitry, digital amplification is predicted to dominate the industry in just a few years. Infinity will be right there.

Low Resonance Enclousres

For more natural sound reproduction, internal bracing is used to reduce cabinet vibration and minimize unwanted background noise.

Don't get Rattled

Low Resonance Enclosures

Loudspeaker enclosures can have a significant effect on sound, and often it’s not good. Vibrations in the cabinet can create bothersome resonances that interfere with audio quality. Infinity engineers used room-friendly design principals and studied the role of the cabinet in loudspeaker performance.

They developed low resonance enclosures with internal bracing to reduce vibration. A precise scanning laser is used to optimize placement of bracing to stabilize the cabinet so it won’t affect performance. The result: clean, clear sound.
