Klipsch The Sixes Powered Speakers – Real Walnut, Like New

A complete, high-performance stereo system in a beautifully styled, real-walnut-veneered pair — the Klipsch Heritage “The Sixes” powered monitors bring together classic Klipsch horn-loaded acoustics, a built-in 200-watt amplifier, and modern digital connectivity in one handsomely designed package.

Part of Klipsch’s acclaimed Heritage Wireless series, The Sixes are designed to replace an entire traditional stereo stack. With a built-in 200-watt custom-engineered amplifier delivering 100 watts per channel, an internal 24-bit/96 kHz DAC, Bluetooth wireless, and a genuinely useful complement of wired inputs, there is no need for a separate receiver, integrated amplifier, or DAC — plug in a turntable, TV, computer, or streamer and the speakers do the rest.

Each cabinet features a 1-inch titanium-loaded tweeter loaded in Klipsch’s signature Tractrix horn, paired with a 6.5-inch long-throw woofer in a ported enclosure. The result is the effortless dynamics, crisp detail, and horn-loaded clarity that have defined Klipsch for generations — now delivered from a pair of self-contained bookshelves that can dominate a dedicated two-channel system, serve as the heart of a vinyl setup, or deliver remarkably engaging sound from a television.

Connectivity is genuinely comprehensive. The rear panel offers a pair of RCA inputs with a phono/line switch and ground screw (a moving magnet phono preamplifier is built in for direct turntable connection), a 3.5mm mini-jack line input, a digital optical (Toslink) input, a USB digital input for direct connection to a PC or Mac, Bluetooth wireless streaming, and a single RCA subwoofer output for adding low-frequency reinforcement. The tactile spun-copper switches and knobs speak to the quality of the design throughout.

The cabinets are finished in real walnut wood veneer — notably warmer and more premium in presentation than the vinyl-wrapped finishes used on most lifestyle powered speakers — with matching magnetic grilles that complete the classic Heritage look. The included wireless remote control is present and fully functional, allowing full control of volume, source selection, and playback from the listening position.

This pair is in like-new cosmetic condition, presenting beautifully in every respect, and has been thoroughly inspected and tested to confirm full functionality.

Klipsch began in Hope, Arkansas, in 1946, when Paul W. Klipsch started building his corner-horn Klipschorn, and its Heritage speakers are still built by hand in Hope. We carry Klipsch towers, centre channels, bookshelf speakers and subwoofers. We've had more than 160 Klipsch listings so far. Every used Klipsch here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program.

The Klipsch story, 1946 to today

Paul W. Klipsch was posted to Hope, Arkansas, in 1941 as an Army officer. He patented his corner-horn design in the mid-1940s and founded Klipsch in Hope in 1946; Klipsch says its first speaker was built by hand there that year, with the horn made in a tin shed. He hired his first employee in 1948.

The Heritage line. The Klipschorn of 1946 was followed by the Heresy (1957), designed as a centre speaker to sit between a pair of Klipschorns, the Cornwall (1959), the La Scala (1963) and the Forte (1985).

A new generation. Fred Klipsch bought the company from Paul Klipsch in 1989, and headquarters later moved to Indianapolis. Paul Klipsch died in 2002 at 98. The Reference Series arrived in 1999.

A Canadian connection. In 2006 Klipsch bought Audio Products International of Toronto, with its Energy and Mirage brands. Audiovox, later VOXX, bought Klipsch in 2011, and Gentex bought VOXX in 2025.

Which Klipsch is which?

Heritage: the Klipschorn, Heresy, Cornwall, La Scala and Forte, built to order by hand in Hope. Drivers change between generations, so identify the version.

KG series (mid-1980s to early 1990s): lower-priced horn-tweeter floorstanders such as the KG 4 (1985 to 1992) and KG 5.5.

Reference (1999 onward): horn-tweeter towers, bookshelf speakers and centres, from the RB-5 and RF-7 to the later RF, RB and RC models.

Synergy (late 1990s and 2000s): such as the KSF 8.5 and the SF-1.

Subwoofers: powered models such as the RPW-10.

Buying used Klipsch: what to check

Horn diaphragms. The compression drivers in older Klipsch speakers age; owners report tired midrange diaphragms on Heritage models and raspy tweeters on some KG pairs. Listen to each horn on its own at a moderate level.

Reference tweeters. A crackling tweeter can be a loose connection, and owners say these tweeters can fail if played very loud.

Crossovers and passive radiators. Many Heritage and KG owners recap their crossovers, and KG passive radiators can have cracked surrounds.

Modifications. Aftermarket diaphragms and crossovers are common upgrades on Heritage and KG models. Ask what has been changed.

Where it was made. Heritage models are built in Hope. Check the label before calling any other Klipsch "made in USA".
