A speaker whose revolutionary concepts ... will obsolete all existing speaker technologies. Including our own.The Infinity-Watkins Dual-Driver Woofer A revolutionary new driver employing two voice coils, this device solves what has been an unsurmountable problem in speaker enclosures: inherent characteristic resonance. No more impedance peak. No more characteristic resonance. No more back-EMF problems. Your amplifier sees only a flat impedance curve; you hear bass energy of astonishing accuracy, life-like presence and power. At the same time, Infinity was developing... Our Samarium Cobalt EMIT Line Source Samarium Cobalt is the most magnetically powerful material in existence. We utilize it in our Electromagnetic Induction Tweeter--the magnetic analogue of the electrostatic (without any of its disadvantages) in a 48" Line Source creating a fan-shaped cylindrical wave-front of high frequency energy. You hear high frequency stereo imaging with an accuracy never before possible. Then we designed... Our Midrange Line Source This usually treated grouping of six high-definition 1 1/2" dome midrange drivers has been designed with careful attention to phase and acceleration capability, eliminating the problem of phase discrepancy. And we added... Our Midbass Coupler This critical element in our acoustic design has a transmission-line configuration and is precisely phased to match the acceleration times and acoustic output between the Infinity-Watkins Woofer and our Midrange Line Source. Approximately 500 of all musical fundamentals lie between 200 and 600 Hz, and we insist upon absolute accuracy in this critical musical range. -- -- -- -- -- Nothing like it has ever been heard. We believe this radical change in speaker designs which "opens up" frequencies from 18Hz to 32 kHz (±2 db) to previously unheard-of levels of power, cleanliness and depth will change the course of audio history. Again. Certainly we've amplified our own thinking; you will now see elements of the Quantum Line Source incorporated in a new family of Infinity speakers. By creating the world's first Electro-magnetic Induction Tweeter; by utilizing it in a multiple configuration to produce a line source of high frequency energy; by introducing a radically new method of producing bass frequencies with no enclosure resonance peak and by configuring all drivers in a phase-coherent homogeneity, Infinity has created an instrument that stands at the limits of speaker technology and stands alone. No longer do you have to choose between the delicacy of music produced by a full-range electrostatic or the power of a large bass horn. The QLS does it all. And more. Listen to the opening of the first movement of the Horenstein Mahler 3rd (on Unicorn and Nonesuch). It will leave you gasping. Its power and the clarity of its inner voices have never been heard like this. Or Janice Ian; her presence and warmth becomes so real you could reach out and touch her. Or Fleetwood Mac; the sledgehammer impact and detail of low frequency content is absolutely staggering. Suggested retail is $1100 a side (15% extra in rosewood). A large price for perfection? But don't let that deter you from asking for our Quantum Tech Paper which explains why and how we did what we did. Most important: listen. You might just agree with us that the Quantum Line Source is the state-of-the-art speaker. We get you back to what it's all about. Music.
