KLH Model Four Three-Way Acoustic Suspension Loudspeaker

The KLH Model Four is a compact 3-way acoustic suspension floorstanding loudspeaker built for high-fidelity sound in real-world listening spaces. Designed to bridge the gap between the Model Three and Model Five, this premium KLH speaker combines an 8-inch pulp-paper cone woofer, a dedicated 4-inch midrange driver, and a 1-inch aluminum dome tweeter to deliver tight bass, natural vocals, detailed highs, and a full-range soundstage from a room-friendly cabinet.

With its shallow cabinet depth, 13-inch-wide front baffle, and included 6-degree riser base, the Model Four is ideal for apartments, condos, living rooms, listening rooms, and design-focused interiors where placement flexibility matters. KLH acoustic suspension technology helps produce accurate, controlled bass without relying on a ported enclosure, while the Three-Position Acoustic Balance Control lets listeners fine-tune the mid and high frequencies to match reflective, neutral, or heavily furnished rooms. Finished with mid-century modern styling, a magnetic grille, five-way gold-plated binding posts, and a structurally reinforced MDF enclosure, the KLH Model Four delivers serious stereo performance in a compact, elegant loudspeaker design.

What It's Good At:

• Room-friendly high-fidelity sound: Acoustic suspension design delivers controlled, accurate bass with flexible placement near walls or in tighter spaces.
• Balanced 3-way performance: Separate woofer, midrange, and tweeter drivers help create clean vocals, detailed highs, and dynamic full-range playback.
• Compact floorstanding design: A shallow cabinet and included 6-degree riser base provide a premium listening experience without a bulky footprint.
• Custom room tuning: Three-Position Acoustic Balance Control adjusts output above 400Hz for bright, neutral, or more absorptive rooms.
• Premium construction: Structurally reinforced ¾-inch and 1-inch MDF, gold-plated binding posts, and quality driver materials support long-term performance.
• Modern KLH heritage styling: Mid-century inspired design, finish options, and a magnetic grille make the Model Four easy to integrate into refined living spaces.
