Large Klipsch RB-61 II Bookshelf Speakers Boasting 400 Watt Peak Power Handling; Very Efficient

From Klipsch:
“Because compromise isn’t an option, the Reference Series RB-61 lets listeners experience all the power, detail and emotion of cinematic spectacles and riveting concert performances. With its superior technology and elegant design, this speaker definitely stands out in a crowd.

Exclusive Tractrix® Horns have always been the key component of this critically acclaimed series. In the RB-61, this technology has been refined to include improved throat geometry for a more genuine, lifelike sound. Behind the horn lies a 1-inch titanium tweeter with a large ceramic motor structure to provide a unique combination of precision, clarity and effortless power.

The RB-61 employs a 6.5-inch woofer for a solid bass foundation. This Cerametallic™ woofer with inverted copper dust cap exhibits a very high stiffness-to-mass ratio and superb damping characteristics.

The RB-61’s front-firing port eliminates turbulence noise and makes installation into custom cabinetry a breeze. Increased baffle ribbing around the horn mouth dramatically improves acoustics across the sonic range. For signal purity and perfect driver integration, the crossover on the RB-61 features the finest components and Klipsch custom internal wiring.

The RB-61 comes with a low diffraction, magnetically attached grille to further accentuate the elegance of this speaker.”

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".
