KLH Windsor 12 Subwoofer Overview

One of the most hallowed names in the history of home audio, KLH is back with a full line of new speakers – and a rededication to the company’s original mission to deliver an affordable audiophile experience to all. KLH’s new high-value Windsor 12 subwoofer can serve as the exclamation point to that line, and as the foundation of any top-quality home theater. Its 12-inch low-frequency driver is formed of a proprietary composite of treated paper, Kevlar, CSX and fiberglass, coated with polyglass and driven by a capable matched amplifier that pumps out 200 watts continuously. The rear-ported bass reflex MDF cabinet helps the system stretch down to 32 Hz. A full set of controls on the back allows you to tweak the sub to your system – whether KLH’s own tone-and-style matched speaker line or your favorite theatrical surround set – and the whole package is wrapped in attractive black oak finish.

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 Windsor 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, amped to the max

The Windsor 12 starts with a 12-inch high-excursion driver formed of KLH’s proprietary composite of woven Kevlar/CSX/Fiberglass/paper, coated in polyglass and rigid enough to move without distortion and light enough to react quickly to the signal. The Class D digital amplifier cleanly supplies 200 watts continuously or 400 watts at peak. Every explosion and every drum kick lands like a punch.

Built to deliver

The high-density MDF cabinet is reinforced, finished in attractive black oak, and ported via rear slot. That bass reflex system strengthens the bass, and helps the Windsor 12 deliver frequencies down to 32 Hz.

Full range of controls

The Windsor 12 handles both LFE connections to a surround receiver and line inputs for other systems. And 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 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.
