Quad - S-4 - Tower Speakers (Pair)

Most audiophiles will jump at the chance to hear a high-grade ribbon tweeter, just like the 1.75 x 0.5-inch true ribbon type found in the Quad S-4 tower speaker. Renowned for their incredibly detailed, clean, smooth, and fast sound, ribbons are driven directly by your amplifier and bypass the information loss common to conventional dome types. They're also normally only found in speakers commanding super-premium price points. All of which alone makes S-4, available for nearly $600 off, a very special component. But this three-way speaker offers so much more – including fatigue-free performance, stunning coherency, and sharp-shooter imaging that will repeatedly draw you into the recording.

Doubtlessly, one of the first things you'll notice about the English-designed S-4 is how composed, pure, finessed, and clean it plays with all types of music – characteristics that extend to its mannered ways with dynamics and low-frequency response. A sophisticated crossover network handles the virtually seamless handoff between the tweeter, four-inch woven Kevlar midrange driver, and pair of five-inch woven Kevlar woofers. To ensure superb low-end control, scale, stability, clarity, and depth, the drivers pair with three five-inch auxiliary bass radiators (ABRs). All you need to do is position your S-4s a foot or so from the wall and you're golden.

And we're going to bet you won't mind having the 45.2-pound S-4 on display in your room. Complete with spiked outriggers that mount onto a metal base, these babies look gorgeous, merging contemporary sleekness and traditional elegance. Graced with Italian-inspired rounded top edges at the front and rear, each tall, slim cabinet comes comprised of alternate layers of MDF and high-density particleboard with circumferential internal bracing that reduces panel resonance below the threshold of human hearing. All the better for you to experience the speed, agility, and airiness with which S-4 conveys music – qualities certain to mesmerize your attention and increase your bond with your favorite artists.
