Description

Comes with a 90 day warranty. Intended for large-scale venues such as concert halls, auditoriums or stadiums. This particular speaker was purchased for a 78,000 seat stadium at a Big Ten school; however, due to a last-minute design change it was never installed. It is currently in storage with more than a dozen other 900-series speakers. They are all in PERFECT working order, never used or damaged in any way, but we are anxious to sell them to free up much-needed storage space.

Also, please note, this speaker (along with the rest of the speakers intended for this system) has been WEATHER-PROOFED. It has a durable fiberglass shell designed to protect it for extended outdoor applications, though it can be used indoors as well.

What's Included

Completely unused and functional KF920 speaker with fiberglass weather-proof cover.

Product Information

KF920

KF920

The KF920 is a dedicated mid frequency long throw/downfill module engineered for use with Phase PointSource Technology digital signal processing in the creation of PPST arrays. It provides such high output of mid frequency information that care should be taken with its use. Listeners in its immediate nearfield at maximum output may suffer permanent damage to their hearing. The system comprises three cells each consisting of a specially designed 10-in mid frequency cone loaded on a 30deg horizontal coverage SimplePhase horn with phase plug. Vertical coverage is determined by PPST processing. PPST processing focuses the output of the three cells onto the main axis while providing smooth frequency response and appropriate attenuation at points below the horizontal axis up to -60deg. This allows a single KF920 mid frequency module to provide coverage over an area from just 25 feet to over 600 feet from the array. SimplePhase horns were specially designed to facilitate the PPST process. Horizontal coverage is an idealized 30 degrees over the entire operating bandwidth. Unlike Virtual Array Technology's complex horn flares designed for control of individual drivers, the simple lines of the SimplePhase horns produce phase coherent summation with other drivers within the module. A toggle switch controls the KF920's only passive filtering which provides appropriate settings for modules located in inner or outer columns. Outboard digital signal processors must provide all other system control.

Applications
The KF920 PPST long throw/downfill MF module is engineered for use only in KF900 Series arrays implementing PPST digital signal processing. It is not intended for stand alone use of any kind. With appropriate PPST processing, the KF920 provides a highly focused beam of vertical MF coverage that can project over 600 feet. PPST processing allows the same KF920 to provide downfill coverage with smooth frequency response up to -60deg below the horizontal axis. Applications such as high energy concert tours may require two KF920 modules per column to generate the desire mid range level. In such a case, the specific processor settings for that dual module configuration must be implemented.
