The Klipsch Forte IV is a three-way Heritage floorstander built around a 12-inch woofer, a K-702 midrange compression driver on a Tractrix horn, a K-100-TI titanium tweeter, and a rear-mounted 15-inch passive radiator that extends bass response from a slim cabinet. The result is full-range horn sound in a relatively compact footprint. Book-matched veneers are assembled in Hope, Arkansas. Sold and priced per pair.
Why This Model Matters
First launched in 1985, the Forte became the best-selling Heritage speaker of its era thanks to its blend of horn efficiency and living-room-friendly size. The fourth generation carries that legacy with 99 dB sensitivity and 38 Hz low-end from its passive-radiator design, offering much of the Cornwall's character in a narrower cabinet.
