The Electro-Voice Sx80T is a compact, two- way, high-efficiency, constant-directivity speaker system for sound reinforcement and monitoring. The small size, high sensitivity and high power-handling capacity of the Sx80T make it an excellent choice for use in studios, clubs, bars, theaters or other applications. An internal, 60-watt line trans- former with selectable taps allows easy con- nection to 70-volt or 100-volt speaker lines in distributed systems.

Through extensive use of computer-aided design and modeling, Electro-Voice engi- neers have developed a state-of-the-art pro- fessional loudspeaker system.

The high-frequency section of the Sx80T uti- lizes a molded-in 90° x 65° constant-direc- tivity horn. This unique pattern contributes to high intelligibility and aims the speakers output where it is most useful. Vocals sound natural yet "cut through" in reverberant, noisy rooms. In addition, the coverage pat- tern is unusually uniform over its range of operation. The horn's unique, VariPathTM throat geometry helps direct driver output to the corners of the room, to points of cover- age not described in the usual specifications

of horizontal and vertical coverage angles, and to parts of the audience that typically do not receive the strongest coverage.

One of the many other unique features of the Sx80T is the cabinet. Constructed of high- impact polystyrene it provides a stiff and extremely durable enclosure. The cabinet includes M6 threaded inserts for the optional Sx80MB U-bracket.

It also has inserts for installing with an OmniMount® Series 75 mounting system.

The Sx80T’s high-frequency horn is driven by the DH2005 one-inch throat, wide-band- width, titanium-diaphragm driver. This driver uses a unique, convex-drive Time Path™ phasing plug structure (U.S. Patent #4,525,604) for smooth and extended high- frequency performance. The voice coil is coupled to the diaphragm with EV’s exclu- sive Resonant Drive™ Technology. This in- creases and smooths the high-frequency re- sponse and reduces the amount of internal equalization required for flat frequency re- sponse, which extends to 20,000 Hz.

Aself-resetting high-frequency protection circuit, EV’s PRO™ circuit, is included with the Sx80T to prevent against accidental over- drive and improve system reliability. If the

input power to the high-frequency driver exceeds the nominal rating, the protection circuit is activated and reduces the power delivered to the driver by 6 dB. The system will remain in this mode of operation until the input power is reduced to a safe level.

The low-frequency section of the Sx80T is a 203-mm (8-in.) direct radiating woofer in- stalled in an optimally-vented enclosure. This results in exceptionally extended bass response and high efficiency in a very small cabinet.

Ring-Mode Decoupling (RMD™ )

Technology

The Sx80T controls both acoustical and me- chanical ring modes to provide dramatically increased intelligibility, using techniques learned from the development of the Electro-Voice X-array™ concert speakers.

There is much less coloration of the sound from resonating sources, leaving only the in- tended sound to be heard by the audience.

High-Frequency Protection Circuit

The Sx80T crossover includes the Electro- Voice automatically resetting PRO™ circuit for high-frequency driver protection. This circuit permits short-term transients to pass,

SX80T specifications

The Electro-Voice SX80T is a versatile high-performance loudspeaker designed to deliver exceptional sound quality in a wide range of applications. Engineered for both indoor and outdoor use, this speaker is particularly suitable for commercial installations, public address systems, and live sound environments.

One of the standout features of the SX80T is its robust construction. The speaker is housed in a weather-resistant enclosure, allowing it to withstand the rigors of outdoor use while still maintaining audio fidelity. This durability makes it an ideal choice for venues such as parks, sporting events, and concerts.

The SX80T utilizes a powerful 8-inch woofer designed to produce deep, rich bass tones, complemented by a high-frequency driver that delivers crisp, clear treble. This combination ensures a balanced audio output across the frequency spectrum, making it effective for various musical genres and speech applications. The speaker's frequency response spans from 70 Hz to 20 kHz, providing a wide range of sound reproduction capabilities that cater to both music and voice.

Another important technology built into the SX80T is its equalization system. This system allows users to tailor the audio output to suit the acoustics of the specific environment, ensuring optimal performance wherever it is used. Whether you are setting up for a live concert or addressing a crowd at an outdoor gathering, this feature provides the flexibility needed to achieve the best sound quality.

Additionally, the SX80T comes equipped with a transformer for 70V/100V line applications, making it easy to integrate into existing sound systems that require distributed audio in commercial settings. This feature is particularly beneficial for installations in larger venues where sound needs to be distributed evenly throughout the space.

The SX80T's mounting options further enhance its usability. It can be wall-mounted or mounted on a pole, providing versatility in positioning to maximize sound dispersion. The speaker also features a stylish and discreet design, ensuring that it blends seamlessly into various environments without compromising aesthetics.

In summary, the Electro-Voice SX80T is a highly reliable loudspeaker offering impressive sound quality, robust construction, and versatile mounting options. Its advanced features and technologies make it an excellent choice for both live sound and installed audio applications, ensuring that audiences receive powerful and clear sound no matter the setting.
