Features

Dolby Atmos-Enabled: Designed by world-renowned speaker engineer Andrew Jones, the Pioneer Elite SP-EFS73 floor-standing speaker employs state-of-the-art Dolby Atmos technology bringing new life to movie and music soundtracks. The Elite floor-standing speaker from Pioneer is equipped with a vertically-firing Dolby Atmos-enabled driver. To maximize the performance capabilities of Dolby Atmos, the Elite floor-standing speaker utilizes a Dolby-enabled top-firing concentric driver that uses Pioneer's Coherent Source Transducers (CST) technology to achieve the highest performance for the most accurate, uniform sound. In concert with Dolby Atmos, the CST driver fires sound upwards and reflects the sound off the ceiling for an heightened overhead surround sound experience. System requirements needed for Dolby Atmos are as follows:

• Equipment Requirements: In addition to a Dolby Atmos compatible speaker setup, you must have a Dolby Atmos compatible receiver, and Blu-ray Disc Content encoded for Dolby Atmos (all sold separately).
• Room Requirements: The listening room ceiling should have a horizontal flat hard surface (for audio reflection) and a height of 8' to 14'.

3-Way Speaker Design: The Pioneer Elite SP-EFS73 floor-standing speaker features a true three-way design with a two-way CST driver for the highs and mids, plus three 5.25" bass woofers for the low frequencies. That's in addition to the Dolby-enabled top-firing concentric driver used for Dolby Atmos.

Coherent Source Transducer (CST) Technology: The Pioneer Elite floor-standing speaker utilizes Coherent Source Transducer (CST) technology for its tweeter & midrange drivers, plus its Dolby-enabled top-firing driver assembly. This unique driver design dramatically reduces interference between the midrange and tweeter, precisely controlling sound directivity at all frequencies and ensuring that direct and reflected sound arrive at the listening position with identical timing and timbre. It does all this with a 1" tweeter positioned centrally at the apex of the 4" midrange driver. Unlike a coaxial driver, which positions its high-frequency driver further forward of a larger cone, the CST concentric design eliminates audible time domain errors that cannot be avoided when drivers are not aligned on the same axial or vertical plane. The CST drivers are mounted in there own individual enclosure, isolating them from the pressure waves in the main enclosure.

• 1" Tweeter: The 1" soft-dome tweeter delivers smooth, extended response and is positioned in the center of the aluminum midrange driver. A matching horn around the tweeter seamlessly integrates both drivers and creates a continuous surface for the expansion of sound waves.
• 4" Midrange: The 4" aluminum midrange cone exhibits true pistonic action and eliminates break-up within its range of operation. Its cone profile has been optimized for both midrange performance and waveguide directivity. The midrange cone terminates in a double-roll surround designed to minimize wave front disruption while also allowing maximum excursion of the midrange cone.
• Neodymium Magnets:  Driving both transducers (tweeter & midrange) are dual Neodymium magnets that provide powerful and stable flux fields in their gaps.

Three 5.25" Bass Woofers The 5.25" aluminum cone and dust cap of these bass drivers ensure true pistonic action, eliminating break-up modes within their operating range. A large diameter vented pole piece allows unrestricted airflow under the dust cap, reducing unwanted noise caused by turbulent air. An oversized magnet ensures greater bass control, while a 1.5" long throw voice coil improves power handling for full, dynamic bass.

Triple Bass Ports: The Pioneer Elite SP-EFS73 floor-standing speaker features a Bass Reflex cabinet design with three rear firing ports for greater efficiency and bigger bass response.

Curved Cabinet Design: The cabinet of the floor-standing speaker is designed with gently curved sides to eliminate standing waves encountered in typical square-box designs. The tower speaker delivers big sound with a small footprint, and is engineered to be tall, but not wide or deep, for easy placement and precise imaging when you're sitting or standing. The black-finished cabinet integrates perfectly with contemporary and traditional interiors, while a small footprint allows flexible placement in the room.

Gold-Plated Binding Posts: The Pioneer Elite SP-EFS73 floor-standing speaker is fitted with two sets of gold-plated binding posts. One set is used for the "front-of-cabinet" drivers, while the second set is used solely for speaker's Dolby-enabled top-firing driver. Make sure to make the appropriate connections between the speaker and your AV receiver. The binding posts will accept bare wire (up to 10AWG), pin connectors, spade connectors and banana plugs (single or dual).  The speaker's dual sets of binding posts are not bi-ampable or bi-wireable.

Floor Spikes: The included spikes will help stabilize the SP-EFS73 if the speaker is placed on thick carpet. However, we do not recommend using the spikes if you have wood, tile, stone or linoleum floors, because the spikes may damage the floor. You can adjust the height of the spikes so that all four spikes firmly contact the flooring underneath the carpet. The spikes add 1" to the overall height of the speaker.

Placement: Whether the speakers are used in the front or rear surround channels, the tweeter (which is in the center of the midrange driver on the front of the speaker) should be positioned near ear level and the loudspeakers separated a distance approximately equal to the listening distance. Angling the loudspeakers inward towards the listener seated in the center will improve the image stability for non-central listeners. Close proximity to a side or rear wall will enhance the bass performance, although too close (particularly a corner location) and the bass may be unnaturally high and image performance may be degraded. Best results will be obtained when the loudspeaker is placed approximately 2 feet from the wall. If a corner location is unavoidable, try to position the loudspeaker so that the distance to the rear wall is not equal to the distance to the side wall.
