Compact speakers designed for listeners
When a product really impresses me I'll call up friends to come over and check it out. Several folks have heard and been amazed by Quad's S-2 speakers. Much of their open, detailed sound quality comes from the ribbon tweeter — a real rarity for speakers in this price range. Whether you like your music loud or soft, acoustic or electric, these speakers tell the truth. And if you love vocals, these little gems can really sing.
I'm a fan of bookshelf speakers and have brought many models home over the years for extended auditions. The S-2s may be the best-sounding $1000/pair speakers I've ever heard.
From the Stereophile review
"...the S-2 is fabulously dynamic, well extended, pure and clean in its revealing upper-frequency range, and offers the best low-end bass traction of any stand-mounted speaker I've heard in my MacDougal Street digs. Absolutely recommended.”

Quad's ribbon tweeter lets the music flow
Quad has been using ribbon drivers in its speakers since 1949, so they've learned a thing or two. A ribbon tweeter produces sound in a way that's simpler and more direct than the more common dome tweeter.
In a dome tweeter, the signal from your amplifier drives a voice coil, which is connected to the dome-shaped diaphragm, but only around the circumference, so a bit of musical information may be lost.
In a ribbon tweeter, the metal ribbon is suspended in a strong magnetic field. Basically, the diaphragm is the voice coil, so it's always under the control of the music signal from the amplifier. Because the ribbon is directly driven by the amplifier, its resolution of musical detail is extremely high.
Ribbons have always been prized for their pure, clear sound, but they haven't always been very rugged. Quad's ribbon tweeter is made from a lightweight metal alloy that is strengthened by a thin layer of polycarbonate. This sandwich construction makes the tweeter robust enough to handle high-powered amplifiers.
So how does the S-2's tweeter sound? Smooth, detailed, and "fast," yet totally non-fatiguing.
A 5" woofer with real punch and impact
To handle the mid and low frequencies, the S-2 relies on a 5" woven-Kevlar® mid/bass driver. Its small size keeps it nimble in the midrange, and helps it blend seamlessly with the extremely quick ribbon tweeter. But it can also reproduce electric bass notes with a bit of heft.
The S-2 cabinet uses a sandwich construction of alternate layers of MDF and high-density particleboard to reduce panel resonance to below the level of audibility.
The ribbon tweeter's shape radiates sound in a wide horizontal arc, while its vertical dispersion is purposely limited to reduce interaction with the floor or ceiling. For that reason, it's especially important to place the speakers so that the tweeters are at ear level. Using 24" stands should do the trick in most systems.
To hear the S-2s at their best, you should drive them with at least 50 watts per channel of high-quality amplification. The S-2s go surprisingly low for their size, but for truly full-range sound, I suggest pairing them with a high-quality powered subwoofer.
Quad's history of innovation
Founded in 1936 to build public address systems, Quad introduced two of the most important speaker innovations of the past century: the first ribbon-based home speaker, in 1949, and the first full-range electrostatic speaker, in 1957. Today, Quad speakers and electronics are still designed and engineered in England, and are manufactured in China.
