Klipsch Quartet (1989–1996)

Name: Klipsch Quartet
Brand: Klipsch

At 42 pounds and just over two feet tall, these floorstanders punch far above their weight with a 98 dB sensitivity that makes even 15 watts feel like a thunderstorm.

Overview

The Klipsch Quartet was produced from 1989 to 1996. It was a more accessible alternative to Klipsch's flagship floorstanders, with the brand's high-efficiency, horn-loaded sound at a lower price. It was built in Hope, Arkansas. The sound is loud, fast and present. Owners report using it with everything from vintage tube receivers to modern solid-state amps, which the 8-ohm nominal impedance allows.

The cabinet is small, 24 inches tall and 13.5 inches wide, but the sound is full. It's a 2-way design with a 10-inch Cerametallic cone woofer and a rear-firing bass reflex port. The vented enclosure extends bass without a powered subwoofer, though real-world performance depends heavily on room placement. Some user reports put the weight closer to 55 pounds. The manufacturer's specification is 42 pounds per cabinet, and the difference likely comes from finish or internal damping materials.

98 dB Sensitivity with Horn-Loaded Clarity

The 98 dB sensitivity (1 watt @ 1 meter) is the defining trait. It gives concert-level dynamics with minimal amplifier power. Owners of classic Marantz, McIntosh, and Sansui receivers like it, and even 15-20 watt tube amps can drive it to startling volume without strain. The efficiency comes from a 1-inch titanium diaphragm compression driver on a 90° × 90° Tractrix horn, a design Klipsch pioneered to control dispersion and minimize diffraction. The high end is fast and transparent, and it renders vocal sibilance and string overtones with precision. The on-axis focus confines the best listening to a fairly narrow sweet spot. Off-axis, the treble rolls off quickly. That's a trade-off of horn loading, and some find it immersive while others find it fatiguing over long sessions.

10-Inch Cerametallic Woofer with Passive Radiator Extension

At the low end, the Quartet uses a 10-inch Cerametallic cone woofer with a rigid aluminum structure and rubber surround, paired with a rear-firing bass reflex port. Bass response extends down to 45 Hz, which gives it an advantage over conventional ported designs of similar size. The passive radiator adds low-frequency output without the chuffing noise of a port, but it also makes the cabinet more sensitive to placement and room boundaries. Owners report that the rubber surround dries and cracks after 25+ years, causing distorted bass and reduced output. That's a common failure point. Reconing services or surround replacements fix it, typically at $100-$150 per driver. Well-maintained units keep tight, rhythmic bass that works well with rock, jazz, and vocals. They lack the subsonic depth modern electronic music needs.

1.7 kHz Crossover with Passive Network Integration

The passive crossover operates at 1.7 kHz, a point chosen to avoid the critical midrange region where vocal intelligibility resides. This helps preserve clarity and minimize phase distortion between the horn-loaded tweeter and the mid-bass driver. The network uses high-quality components, but long-term reliability depends on the electrolytic capacitors, which can dry out over decades of use. A treble loss or imbalance often signals capacitor degradation. Modern metal-film replacements fix it. Crossover rebuild kits are available from specialty vendors like Critesspeakers.com, and forums confirm active support for recapping projects. The exact topology isn't documented in public specs. Klipsch described its approach as "time-tested design principles and dawning technology."

Historical Context

Paul W. Klipsch founded Klipsch & Associates in 1946, and the company built its name on high-efficiency, horn-loaded speakers that prioritized dynamic range and realism. The Quartet was introduced in 1989, when CDs were dominant and tube amplifiers were waning. Its 98 dB sensitivity kept it compatible with both vintage and modern gear. It was positioned as a floor-standing counterpart to the Klipsch Heresy and a slightly more affordable sibling to the La Scala. Period marketing said it was "destined to become yet another classic bearing the Klipsch name." Production ran from 1989 to 1996.

Collectibility & Value

The Klipsch Quartet holds moderate to high collectibility, particularly among Klipsch loyalists and enthusiasts of high-efficiency systems. Paul Klipsch emphasized that speaker quality makes a far greater difference than amplifier cost High-Fidelity (February 1968, p.37). Well-maintained pairs in original finishes, especially rosewood and cherry, typically sell for $400 to $700 per pair, and original, unmodified units command premiums. Black ash models are more common and often priced lower. Individual parts turn up regularly on the secondary market: tweeter pairs (K-76-K) have sold for $150, crossover networks for $25-$195, and grill covers for $325. A historical listing shows a pair selling for $25. Owners praise a "lively, dynamic, and highly engaging sound signature" and the ability to deliver "concert-like levels" even on low-power amps. Maintenance is straightforward. Clean the horn with a soft cloth and avoid direct sunlight to prevent veneer cracking, and recap the crossover for long-term reliability.
