Klipsch Heritage Heresy IV

Features

Heresy IV: First introduced in 1957, the Heresy started life as a compact center channel speaker for the Klipschorn in three-speaker stereo arrays. The Heresy is a compact, three-way design that uses horn-loaded compression drivers for midrange and treble reproduction and a direct radiating 12"woofer for the low frequencies.

3-Way Design: The Klipsch Heresy IV loudspeaker features a three-way design that uses horn-loaded compression drivers for midrange and treble reproduction, plus a direct radiating 12" woofer for the low frequencies.

• 1" Tractrix Horn Loaded Tweeter: The 1" titanium diaphragm compression driver (K-107-TI) is coupled to a Tractrix Horn for smoother high-end response with greater extension, enhanced imaging, and more powerful dynamics.
• 1.75" Tractrix Horn Loaded Midrange: The 1.75" polyimidediaphragm compression driver (K-702) is coupled with a horn for detailed, accurate midrange sound.
• 12" Fiber-Composite Cone Woofer: The 12" fiber-composite cone woofer (K-28-E) delivers powerful low frequencies. The 12" woofer also employs a treated cloth surround for added efficiency and flexibility.

Crossover Network: For signal purity and perfect driver integration, the crossover (HF: 4500Hz/MF: 850Hz) on the Heresy IV features the finest components and Klipsch custom internal wiring.

Rear Tractrix Port: The rear Tractrix port of the Heresy IV floorstanding loudspeaker is perfectly matched to the cabinet and woofer, creating ideal airflow with minimal distortion and turbulence even at the lowest frequencies. Klipsch Tractrix ports have custom designed inner flares that help reduce air turbulence entering the port. Less turbulent air helps reduce port noise for cleaner, more powerful bass.

Dual Binding Post Speaker Terminals: The Klipsch Heresy IV loudspeaker has two sets of binding posts connected by jumpers. Using the dual binding posts, you can bi-amp or bi-wire the speakers. The binding post terminals will accept banana plugs (single/dual), pin-connectors, spade-connectors, and bare wire.

• Bi-Wiring: Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers. Run separate speaker wires to the low & high frequency drivers from a single amplifier (the upper set of binding posts are for the high frequency drivers; the lower set of binding posts are for the low frequency drivers).
• Bi-Amping: Bi-amping allows you to use separate amplifiers for the high & low frequency sections of your loudspeaker for greater dynamic range & lower distortion. We recommend that your separate amplifiers have identical gain to preserve the speaker's voicing balance.

Note: If you decide to bi-wire or bi-amp, you must remove the jumpers between the terminal posts (failure to do this could result in damage to your amplifier and loudspeakers).

Placement: The Klipsch Heresy IV loudspeaker will perform well in a variety of locations. Corner, floor placement will deliver the highest degree of low bass reinforcement and the pre-installed slant riser base helps to compensate for the Heresy's short stature. This riser may be removed for shelf or cabinet placement. Self-stick rubber pads are supplied for attachment to the bottom of the cabinet to prevent scratching of shelves and hard surfaces. Best results will be achieved using the following general guidelines.

• Place on a common wall 6' to 15' apart and position them equidistant from the wall behind the speakers.
• Angle speakers toward the listener and even with or forward of any adjacent obstructions.
• Placing them near a corner or wall provides the greatest amount of bass while moving the speakers away from room boundaries reduces bass.
• Asymmetrical placement of a pair of speakers from adjacent side walls can smooth room-induced bass unevenness.

Note: Experiment with the above guidelines to suit your taste and to compensate for your room's acoustic characteristics.

Heritage Series (Made in the USA): The Klipsch Heritage Series is built and handmade in the USA at Klipsch's manufacturing facility in Hope Arkansas. They are meticulously handcrafted and assembled using the finest quality materials, even down to the highest-grade adhesives and fasteners (no detail goes unnoticed). Each Heritage Series loudspeaker utilizes Klipsch proprietary horn-loaded technology to bring a live music listening experience into the home. All Heritage Series loudspeakers are available in a variety high-quality wood veneers. Klipsch Heritage loudspeakers are built to rock the house and stand the test of time.  This is a speaker that will be handed down for generations to come.

4 Principles of Klipsch Sound: Paul W. Klipsch believed four principles to be the foundation for great sound. They continue to drive the design of every new Klipsch speaker, today and tomorrow.

• High Efficiency & Low Distortion: Klipsch horn technology is highly efficient, providing more accurate sound with less power and less distortion - resulting in louder, cleaner audio. Klipsch's Law: Efficiency is inversely proportional to distortion.
• Controlled Directivity: Klipsch horn technology accurately directs sound to the proper locations, which, in turn, creates a more lifelike soundstage without wasting acoustic energy where sound is not needed or desired.
• Wide Dynamic Range: The softest sounds are reproduced with remarkable clarity and the loudest sounds are delivered without harshness or distortion - with the greatest possible range between the softest and loudest sounds.
• Flat Frequency Response: Audio is delivered without frequency bias - no unnatural highs, mids or lows - reproducing recorded sound as accurately as possible without colorization.
