Your chance to own a set of rare and iconic Infinity QLS-1 speakers. The flagship of the Infinity Speaker line. These were owned by my Uncle, who recently past away. All original speakers but the woofers were refoamed at some point. The cabinets are absolutely beautiful and in superb condition. The covers also are in amazing original condition. The speakers work, however the crossovers should be rebuilt at some point. These rare speakers rarely come up for sale, so now is your chance to own a pair. They are located in Tucson, Arizona. Will not ship. They must be picked up in Tucson. QLS-1is a 4-way 17 driver tower consisting of 8 front firing EMITs, 1 rear firing EMIT, 6 soft dome midrange drivers, 1 mid-bass coupler driver in a tube TL alignment, and 1 Watkins 12 dual-drive woofer (poly cone). According to Infinity's literature of the time, the QLS uses a phase-aligned passive crossover network and is capable of 18Hz to 32KHz +/- 3db response. Each tower is about 6ft tall and weighs 190lbs! Cabinets are constructed pf 1 inch particle walnut. Lot of speaker weight is attributed by the thick & heavily damped cabinets. QLS are a dipole design with rear firing tweeter (can be turned off) and mid bass port is open to the back. They throw a wide and huge soundstage with great imaging and dynamics. Speakers disappear while playing music and it seems like music is there...floating and not directly coming from them. Crystal clean highs with a lot of air -- 48 inch strip of EMIT drivers! (Not many speakers I heard have this kind of highs -- silky smooth and extended), sweet midrage, and thunderous bass -- no need for a subwoofer! Dual voice coil design produces astonishingly accurate, tight and deep bass all the way down to 18hz!
