Meet the Forte IV

The Klipsch Heritage Forte IV Floor-standing Speaker (pair) is one of the most celebrated designs in the Heritage lineup, combining a relatively room-friendly footprint with the scale, immediacy, and dynamic realism Klipsch is known for. First introduced in 1985 and refined for its fourth generation, this speaker blends classic Heritage styling with updated acoustic engineering for a presentation that feels vivid, powerful, and emotionally direct.

For listeners who want the energy and live-music feel of a true high-efficiency loudspeaker without stepping into an oversized cabinet, the Forte IV is a compelling centerpiece for a serious two-channel system.

Highlights & Benefits

• High-efficiency Heritage performance — with 99dB sensitivity, the Forte IV is easy to drive and especially attractive for lower-powered tube amplifiers as well as refined solid-state electronics.
• Three-way horn-loaded architecture — the horn-loaded midrange and tweeter deliver the speed, projection, and controlled dynamics that make Klipsch Heritage speakers so distinctive.
• Updated fourth-generation refinements — the K-702 midrange compression driver, revised horn implementation, and updated network help produce stronger detail, better consistency, and a more accurate sweet spot.
• Fuller low-frequency authority — a large rear-mounted 15” passive radiator works with the 12” woofer to produce bass weight and extension that exceed what the cabinet size might suggest.
• Handcrafted Heritage finish quality — real wood veneers are book-matched and pair-matched for a more premium, furniture-grade presentation.
• Classic design with modern refinement — the Klipsch Heritage Forte IV Floor-standing Speaker (pair) preserves the personality of the original while bringing meaningful acoustic improvements to a legendary model.

Technology & Design

Horn-loaded midrange and high frequency system — the Forte IV uses a titanium diaphragm high-frequency compression driver and a polyimide midrange compression driver, each coupled to purpose-designed horns for efficiency, detail, and strong dynamic contrast.

Large passive radiator bass system — the rear-mounted 15” passive radiator works from acoustic pressure generated by the active woofer, helping the speaker achieve fuller bass extension and stronger low-frequency output without a conventional port.

Heritage network and cabinetry — Klipsch revoiced the network with premium components and continues to hand-assemble the enclosure in Hope, Arkansas, pairing classic construction values with refined acoustic tuning.

In a carefully matched setup, the Klipsch Heritage Forte IV Floor-standing Speaker (pair) delivers a combination of speed, scale, tonal character, and physical impact that few speakers at any size achieve in quite the same way.
