Features

1" Horn-Loaded Tweeter: The Klipsch RP-4000F floorstanding loudspeaker features a 1" Titanium LTS Vented Tweeter with a Hybrid Tractrix Horn for exceptional high frequency response, detail, and dispersion. Klipsch proprietary Tractrix horn-loaded technology ensures high-frequency energy of the RP-4000F floorstanding speakers are aimed directly at the listener and reduces unwanted, artificial reverb caused by indirect sound bouncing off walls - meaning you experience the most clear, detailed, lifelike sound possible.

• Titanium LTS Vented Tweeter: The titanium tweeter diaphragm's light weight yet rigid composition exceeds the performance of aluminum, polymer or silk tweeters. A vented tweeter design reduces standing waves behind the tweeter diaphragm for a smoother high frequency reproduction. Klipsch award-winning Linear Travel Suspension technology leverages a piston motion of the titanium diaphragm that lowers distortion and delivers real-to-life sound. A ceramic magnet housing provides premium performance,
• Hybrid Tractrix Horn Technology: This redesigned 90°x90° Hybrid Tractrix Horn utilizes a circular horn throat paired to a square horn mouth to further improve high-frequency response and extension, while enhancing imaging and dynamics. The Hybrid Tractrix Horn's compressed molded silicon face adds high frequency damping to reduce harshness and horn resonance for a smoother frequency response with improved detail - creating a clean and natural sound. Klipsch also utilizes computer modeled phase plugs that act as a mechanical filter to further ensure a smooth, flat frequency response while protecting the tweeter from damage.

Dual 4" Cerametallic Woofers: The RP-4000F floorstanding loudspeaker utilizes two 4" Klipsch Proprietary Cerametallic woofers. Cerametallic consists of extremely light, rigid materials that can hold shape while being able to deliver lower frequencies with maximum efficiency. The Klipsch Cerametallic cone is matted to a dual-layer, copper-wound voice coil for exceptional conductivity. The 4" woofers are housed in a non-resonating, stamped-steel basket that's secured to a large magnet motor for exceptional efficiency and low distortion.

Rear Tractrix Port: The rear Tractrix port of the RP-4000F 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.

MDF Cabinet: The Klipsch RP-4000F floorstanding speaker features a MDF cabinet with a scratch-resistant, textured wood grain vinyl that seamlessly integrates into almost any room or decor. The enclosure's reinforced MDF construction reduces cabinet vibration for less audible coloration and improved sonic accuracy. The MDF enclosure also features a satin painted baffle with a scratch resistant design for an elegant look without the grille.

Acoustically Transparent Grille: The Klipsch RP-4000F floorstanding loudspeaker comes with a removable, black cloth grille that is magnetic and acoustically transparent. This strong magnetic grille provides protection and a sleek aesthetic look to compliment your home's decor.

Dual Binding Posts: The Klipsch RP-4000F is fitted with two sets of sturdy binding posts allowing to bi-amp or bi-wire the floorstanding loudspeaker. These binding posts ensure a secure connection to many types of cable and connectors. The binding post terminals will accept banana plugs (single only), pin-connectors, spade-lugs and bare wire (up to 10AWG). Two plastic caps will need to be removed to use banana plugs.

• 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.

Cast Aluminum Stabilizer Feet: The Klipsch floorstanding loudspeaker includes pre-installed, cast-aluminum stabilizer feet with rubber pads for safe placement on hardwood, tile, laminate, and vinyl flooring. The cast aluminum feet are mechanically designed to minimize surface area in contact with the floor, decoupling the speaker for faster, tighter low frequencies and more detail. No carpet spikes are included, and the speaker will not support optional carpet spikes or other type of feet.

Application & Placement: The Klipsch RP-4000F floorstanding loudspeaker can be used in a dedicated stereo application or in a home theater application as front and/or rear speakers.

• Front Placement: For optimum performance in a stereo application or as front speakers in a home theater application, Klipsch suggests placing the loudspeakers 6' to 15' apart. They may also be toed-in slightly for better stereo imaging. The listening position should be about 1 to 1.5x the distance separating the speakers.
• Rear Placement: When used as surround speakers in a home theater setup, the speakers should be placed on the walls directly adjacent to the listening position. Another option would be on the wall behind the listening position.

Reference Premiere Series: The Klipsch Reference Premiere series utilizes a redesigned hybrid 90°x90° Tractrix Horn, a vented LTS titanium tweeter, Cerametallic woofer construction, and Tractrix geometry port technology for sound that will envelope you and blow you away. The Reference Premiere series by Klipsch consists of a variety of floorstanding, bookshelf, center, and surround speakers (all sold separately).
