KLH Model Seven Floorstanding Speakers - 3-Way Acoustic Suspension KLH Model Series Flagship Speakers

The KLH Model Seven is a 3‑way, 13″ acoustic suspension loudspeaker that delivers uncompromising accuracy, power and style. Inspired by the legendary Model Five and rooted in the acoustic‑suspension tradition that reshaped hi‑fi history, it combines a wide‑baffle design with modern engineering to produce deep low‑frequency extension and effortless dynamics while remaining forgiving of room placement. Its 13″ high‑displacement woofer, dedicated 5″ midrange driver and 1″ aluminum dome tweeter work together to provide natural, full‑range sound across every genre.

This flagship floorstander features a three‑position acoustic balance control to tailor the speaker’s output to your room, non‑resonant cast‑aluminum driver frames and a structurally reinforced MDF cabinet to minimize distortion. Mid‑century modern styling includes book‑matched wood veneers, a low‑profile magnetic grille and an included matte‑black slant riser base. The Model Seven is priced and sold as a pair and ships with everything needed for installation.

Product Q&A:

Q: What is an acoustic suspension loudspeaker?

A: Acoustic suspension speakers use a sealed enclosure where the air inside acts as a spring for the woofer. This design allows the driver to move more linearly, producing tight, well‑defined bass with low distortion.

Q: What drivers does the Model Seven use?

A: Each speaker features a 13″ high‑displacement pulp‑paper woofer for powerful bass, a dedicated 5″ midrange housed in its own enclosure for vocal clarity and a 1″ aluminum dome tweeter for smooth treble.

Q: How does the three‑position acoustic balance control work?

A: The rear‑panel control lets you tailor the speaker’s midrange and treble output to compensate for room acoustics or personal listening preferences.

Q: What amplifier power is recommended for the Model Seven?

A: KLH recommends amplifiers between 20 and 250 watts. The speakers handle 250 W RMS and peaks up to 1,000 W, offering broad compatibility with quality amplifiers.

Q: What are the dimensions and weight of each speaker?

A: With the slant riser, each speaker measures 41″ H × 18″ W × 12.25″ D and weighs 78.8 lbs. Without the riser, the height is 36″ and the depth is 9.75″ with a weight of 68 lbs.

Q: What comes in each carton?

A: Each carton includes one Model Seven loudspeaker, a magnetic grille, a matte black slant riser base and an owner’s manual.

Q: How does the wide baffle design improve sound?

A: The wide front baffle focuses sound forward and reduces wrap‑around to the sides and rear, minimising reflections from nearby walls and improving imaging. It also makes placement more forgiving.

Q: Why choose the Model Seven over smaller speakers?

A: With its high‑displacement 13″ woofer, reinforced cabinet and acoustic suspension design, the Model Seven delivers deeper bass, higher dynamic headroom and cleaner low‑frequency reproduction than compact speakers, making it ideal for full‑range listening.
