KLH Stratton 12 Subwoofer Overview

One of the most hallowed nameplates in the history of home audio, KLH is back with a full line of new-design speakers – and a rededication to the company’s original mission to deliver an affordable audiophile experience to all. As KLH’s top-of-the-line subwoofer, the Stratton 12 is the exclamation point at the end of that line! Its big 12-inch low-frequency driver is formed of double-spun and heat-treated aluminum, driven by a rugged 2-inch voice coil. And pushing that voice coil is a massive amplifier that pumps out 200 watts continuously. The sealed cabinet makes for tight, clean bass, and the bottom end reaches all the way down to 25 Hz. A full set of controls on the back allows you to match the sub perfectly to your system – whether KLH’s own tone-and-style matched speaker line or your favorite theatrical surround set.

From the heartland, from the heart

The new KLH, located in the USA’s heartland – Noblesville, Indiana – pays homage to the brand by building incredible value into every speaker. The Stratton 12, like the entire line, employs superior materials, designed with decades of engineering experience, to deliver a speaker that looks as good as it sounds, and sounds better than far more expensive competitors. As KLH’s new CEO, David Kelley, tells World Wide Stereo, the goal is to “take KLH back to its roots and founder Henry Kloss’s original mission: to build world-class loudspeakers and radios at affordable prices.”

Big driver, big bass

The Stratton 12 starts with a 12-inch driver, whose cone is formed of double-spun, heat-treated aluminum surrounded by high-density butyl rubber surrounds. That means the driver is rigid enough to move without distortion, light enough to react quickly to the signal, and flexible enough to pump a lot of air.

Amped to the max

The Stratton 12 drives that woofer’s 2-inch voice coil with a Class AB switching amplifier that cleanly supplies 200 watts continuously, or 500 watts at peak power. Each explosion and every drum kick lands like a punch to the gut.

Sealed for quality

The high-density MDF cabinet is reinforced and sealed – which reduces resonances and delivers tighter, cleaner and more accurate bass, all the way down to a room-shaking 25 Hz. And that cabinet is finished in attractive, high-gloss piano black, which means you don’t have to hide it behind a sofa or stereo bench, just place it wherever it sound best.

Full range of controls

The Stratton 12 comes with two inputs – LFE, to connect to a surround receiver with a subwoofer output, and line inputs for other systems. And if you need to tune your sub to match the system, you get volume, phase and crossover frequency controls across the back panel.

A brief history of sound

Back in the 1950s and early ‘60s, a band of pioneering engineers revolutionized the audio world and led the golden age of high fidelity. Among them, possibly the most revered is Henry Kloss, the K of KLH. An inveterate tinkerer and serial entrepreneur, he started some of the most influential companies of the era and beyond, from AR and Advent to Cambridge Soundworks and Tivoli Audio. Kloss is credited with introducing influential innovations including acoustic suspension speakers, Dolby tape recorders and projection TVs. To honor his memory and dedication to the highest fidelity in every product, the revamped KLH named its new speaker line for streets on and around Kloss’ beloved Massachusetts Institute of Technology campus in Cambridge, Mass.
