VARI-Q

DIRECTED COVERAGE HORNS

The next thing in directivity.


The VARI-Q project was conceived to solve the problem of covering a rectangular space from an oblique angle. Typical church sanctuaries and school auditoriums are rectangular in shape and the most likely place for the speaker is hanging overhead facing down at an oblique angle. The front row is wide at the bottom of the pattern but close to the speaker. The back row is narrow at the top of the pattern but far from the speaker. This creates a trapezoid shaped area from the point of view of the speaker. The WRIGHT VARI-Q horn solves the coverage pattern problem by shaping the pattern wide at the bottom and narrow at the top, AND the distance problem by sending 12dB more sound to the back of the room to compensate for the "inverse square" law. [Sound dissapates at a rate of 6dB per double the distance.]

JBL4660 Speaker System
JBL4660 Specification Sheet
  • This speaker was in limited production in the 70's & 80's but was discontinued. Weaknesses were low power handling and a small 1" HF driver which limited applications to small rooms. JBL spent a lot of time and money on this one but never promoted it properly.
  • This cabinet may be retrofitted with WRIGHT Vari-Q horns
ALTEC Vari-Intense Speaker System
VI-15 Specification Sheet
  • This speaker is still in production under the Electro Voice name but it suffers from low power (even less than the JBL) and the HF horn is too small to really be effective. Plus the latest version has a perforated metal grille which severely limits dispersion.
  • I only mention it here because it purports to solve the same problems but the low power and odd shape make it very limited in usefullness.
