The Line Array Effect The line-array effect is achieved by the 0 degree coupling of the enclosures in the array. The inherent advantage of a line array design allows the rear audience to hear nearly the same levels as the front. The PurePath™ horn produces a tight 10 degree vertical x 100 degree horizontal pattern on a single cabinet. Conventional enclosures drop 6dB when doubling the distance to the listener. However, when coupled in a line array this pattern narrows further to produce the line array effect, which drops only 3dB when doubling the distance to the listener. When the straight line of the line array is broken as in the case of a "J" curve, the elements curved at the bottom of the array behave more as a "point source" loudspeaker producing normal output to the closer listeners. The TRx3210 can be deployed in a full curvilinear array with 10 degrees of angle between elements. This produces a smooth "point source" array covering 40 degrees of vertical and 100 degrees of horizontal coverage with only four enclosures. Line Array with J curve Linear Curve Array The PurePath™ Horn Lens and dual 10" Drivers The PurePath™ Horn Lens is CNC machined in-house from acoustically non-resonant Eastern Maple hardwood, providing a very smooth, equal path length wave guide for pure, natural and cylindrically projected highs. The two HF Mylar compression drivers feature a 1-inch exit and a 1.75" voice coil. The PurePath™ Horn Lens places the HF drivers in proper phase alignment with the 10-inch drivers. PurePath Horn Lens dual 10" 1000W peak drivers IP2 UV & Water Resistant Two 10-inch MF/LF drivers feature 2-inch voice coils and power handling of 1000W peak per driver. They are treated for IP2 UV approval, which is also water resistant. These drivers are front loaded and field replaceable. The front steel grills are foam backed for added protection from the elements, and are easily removed for service access. 6
