Never has one speaker system incorporated so many aspects of the state of the art.
The Infinity Reference Standard 4.5
This is a system of breathtaking clarity and detail, yet capable of the awesome punch and power demanded by the finest contemporary digital and direct-to-disc recordings.
The Reference Standard 4.5 frees the intimate warmth of the human voice, the robust sheen of the strings, the fiery attack of the brass, the stab and snap of the bass. The speakers seem to disappear, revealing a concert stage breathing life, delicacy and fury. You hear the musicians, not the speakers.
How does the 4.5 work its musical miraoles? The profoundly accurate bass and midbass are partly the result of a remarkable new cone material, poly propylene. It has dramatically less mass, yet significantly greater internal damping than paper cones or other exotic materials. Our polypropylene piston, combined with our exclusive Infinity/Watkins dual-voice-coil woofer principle creates bass frequencies with the snap and definition of the finest dipoles, yet retains the ultra-low frequency response (flat to 23 Hz) that has made Infinity famous.
The transparent crystalline treble issues from our world-acclaimed EMIT tweeters in dipole array. Midrange warmth, smoothness and unprecedented definition are the progeny of our lustrous new dipole EMIM Electromagnetic Induction Midranges. Like the EMITs, they employ powerful magnets of rare-earth samarium cobalt and etched voice-coils on low-mass diaphragms.
A separate electronic crossover/ equalization unit allows you control over variable source material and room anomalies, either in single or bi-amp mode.
A remarkable technological story. And like all great stories, this one ends where it began: with the music. Which is the real reason you should spend $3000* on the Infinity state-of-the-art Reference Standard 4.5.
Infinity---We get you back to what it's all about. Music.
