Klipsch KG2

A compact two-way that trades the corner-horn scale of its ancestors for a bookshelf footprint — and still delivers that unmistakable Klipsch efficiency.

Overview

The Klipsch KG2 is a two-way loudspeaker that fits the "bookshelf" category in size only. At 15 inches high, 10 inches wide, and 9 inches deep, it's small enough to sit on a shelf or a stand, but the engineering inside is pure Klipsch — which means high efficiency and a sound that doesn't need a monster amplifier to fill a room. Owners report driving them comfortably with modest receivers, a trait that endeared the model to buyers who wanted Klipsch presentation without needing a dedicated power plant.

Described in period advertising as "the response of a Klipschorn, size of a shoe box," the KG2 was pitched at working professionals and home listeners alike. Mix Magazine (December 1983, p.27) introduced it as a quality full-range minimonitor at the SCES show, noting a rear-mounted 10-inch passive radiator and a new crossover and voice coil that provided "an uncommon richness to vocals." That's a fair summary of the KG2's character: it's not the last word in airy detail, but it has a warm, smooth balance that's easy to live with.

The KG2 sits in an odd spot in Klipsch's catalog. It's not a corner horn, not a giant floorstander, not a heritage model with a decades-long production run. It's a compact speaker that happens to carry the Klipsch name and much of the Klipsch philosophy. According to available documentation, the KG series of which it was a part — KG2, KG3, KG4, and KG5 — was described by one owner as having evolved from the Heresy, though that lineage claim comes from a forum post rather than official Klipsch literature. What's certain is that the KG2 earns its place in the family tree on its own merits.

Key Features

8-Inch Long-Throw Woofer

The bass driver is an 8-inch long-throw woofer (200 mm), which is a sensible compromise for a cabinet this size. It's not going to shake the room like a La Scala or a Cornwall, and owners are quick to point out that the KG2's deep bass is limited below about 50 Hz. That's physics — an 8-inch driver in a small enclosure can only move so much air. What it does well is deliver clean, articulate midbass with that characteristic Klipsch punch. The driver's long-throw design helps it move enough air to keep up with the speaker's high sensitivity without straining.

1-Inch Dome Tweeter

Here's where the documentation gets interesting. Retro-Vintage-HiFi lists the KG2 as having a 1-inch dome tweeter (25 mm), while at least one Audio Review forum poster describes it as using a horn tweeter. The sources genuinely conflict on this point, and the fact sheet flags it as unresolved. What multiple listeners do agree on is the result: the high end is smooth and non-fatiguing. One owner who bought a pair secondhand reported being impressed enough to keep them, praising the treble for never becoming harsh or grating over long listening sessions. Whether the driver is a dome or a horn, Klipsch voiced it to be listenable rather than showy.

Passive Radiator Bass Extension

The KG2 uses a passive radiator to extend bass response rather than a conventional port. Mix Magazine (December 1983, p.27) described it as a rear-mounted 10-inch passive radiator providing "substantial, clean bass." The arrangement is a clever way to get more low-frequency output from a small cabinet without the tuning artifacts that ports can introduce. It's a design choice that contributes to the KG2's reputation for sounding bigger than its dimensions suggest — at least down to its actual limits.

Flush-Mount Baffle Design

One of the more unusual aspects of the KG2 is its relationship to wall mounting. According to a forum poster citing Klipsch brochure specifications, the recommended minimum baffle size for flush mounting is 20 × 20 inches, with no recommended baffle depth given. The poster interpreted this as meaning the KG2 was intended to be flush-mounted in a wall, though the brochure itself doesn't explicitly say that. What the spec suggests is that Klipsch designed the KG2 with installation flexibility in mind — it can work on a bookshelf, on stands, or built into a wall, provided the baffle around it is large enough. In practice, most owners seem to have used them as conventional bookshelf or stand-mounted speakers, and the Mix Magazine piece emphasized "exceptional horizontal and vertical dispersion" that allows for a multitude of placement options.

Performance and Sound

The KG2's sensitivity is rated at 94 dB by Retro-Vintage-HiFi, with Hi-Fi Engine agreeing on that figure, though an Audio Review poster cited 93 dB from a Klipsch brochure. Either way, this is a speaker that doesn't need much power to play loud. The high sensitivity means there's little likelihood of amplifier overload, even with amplifiers specifically not recommended for loads lower than 8 ohms — a point made in a later HiFi-Stereo review of the KG2 (May 1993, p.59). The nominal impedance is listed as 8 ohms by both Retro-Vintage-HiFi and Hi-Fi Engine, though the same Audio Review brochure citation claims 6 ohms. For most amplifiers, either figure is manageable.

Power handling is rated at 100 watts max by Retro-Vintage-HiFi, with the Audio Review brochure citation claiming 150 watts. The practical takeaway is that the KG2 will happily work with a wide range of amplifiers — it's efficient enough to sing with 10 watts, yet robust enough to handle a solid 100-watt receiver without complaint, as long as you're not driving it into hard clipping. An early HiFi-Stereo test report (January 1984, p.39) recommended that the driving amplifier have a good infrasonic filter, which is sound advice for any speaker with a passive radiator or port, since very low-frequency content below the speaker's operating range can cause excessive cone excursion.

Frequency response is rated at 60 Hz to 20 kHz ±3 dB by Retro-Vintage-HiFi, while Hi-Fi Engine extends the low end to 56 Hz. The crossover is set at 2,500 Hz, a figure corroborated by both Retro-Vintage-HiFi and Hi-Fi Engine. That crossover point is well chosen for the driver complement, keeping the woofer out of the upper frequencies where it would beam and letting the tweeter handle the frequencies where its dispersion characteristics work best.

Listening impressions from owners paint a consistent picture. The KG2 has a smooth, well-balanced sound with only moderate extra warmth in the lower mids. HiFi-Stereo (January 1984, p.43) noted that the speaker "sounds very smooth and well balanced," and that it rates a place in the Klipsch family tree purely on its own merits. Owners echo that sentiment, describing the sound as warm and pleasant rather than hyper-detailed. One listener noted they were not the most detailed speakers he'd heard, but they have a nice, warm quality that makes them easy to recommend for long listening sessions. The high end is smooth and non-fatiguing, which is more than can be said for many speakers of this era.

The KG2's main limitation, acknowledged by owners and reviewers alike, is deep bass. The 8-inch woofer simply can't reproduce much below about 50 Hz with authority. One owner who used KG2s as rear speakers in a home theater setup noted that the speakers benefit from a subwoofer to fill in the lowest octave. That's not a criticism so much as a reality check — the KG2 is a compact two-way, and expecting it to match a Klipschorn's bass extension would be unfair. Within its operating range, it delivers clean, articulate sound with the efficiency that makes Klipsch speakers so appealing.

Collectibility and Market Position

The KG2 remains a bit of a sleeper in the Klipsch catalog. It doesn't have the cult following of the Heritage line, and it doesn't command the prices of the bigger KG models. Current market pricing isn't well documented in available sources, but the KG2 tends to appear on the used market at accessible prices — a used pair is an inexpensive way to experience Klipsch's approach to speaker design without the investment required for a vintage Heritage model.

Owners who have bought KG2s secondhand report being pleasantly surprised. One Audio Review forum poster who purchased a pair used was impressed enough to buy them, noting that the high end was smooth and non-fatiguing. Another uses KG2s as rear speakers in a home theater setup, suggesting they work well in multichannel applications where their compact size and high efficiency are assets. No common failure modes or maintenance issues have been reported in the available documentation, which speaks to the basic robustness of the design.

For collectors, the KG2 represents an interesting chapter in Klipsch's history — a period when the company was exploring smaller, more affordable designs that could reach a broader market than the corner horns that built the brand. The KG series, including the KG2, KG3, KG4, and KG5, shared a family resemblance and design philosophy. The KG2 is the smallest of the group, and arguably the purest expression of the concept: a compact speaker that delivers Klipsch efficiency and smoothness in a package that fits on a bookshelf.

If you're considering a pair, go in with realistic expectations. The KG2 won't reproduce the deepest bass, and it won't match the sheer presence of a Cornwall or La Scala. What it will do is fill a room with clean, efficient, non-fatiguing sound from a modest amplifier — and do it without taking up half your living room. That's a trade worth making for many listeners, and it explains why the KG2 still finds happy homes decades after it left the showroom floor.
