Carvin's TRx 3000 Series feature column and line arrays loudspeakers accompanied by higher output flyable subs and regional tour level events. Like the TRx 2000 Series, these enclosures are made from road worthy multi-ply Baltic Birch and covered in weather and UV resistant Duratec™ coating. Steel powder coated grills, handles, pole mounts and flyware along with stacking dolly boards and shock mount, tour-duty amp rack cases. All protected by a 5 year warranty.

The TRx3903 is the new era of high output, wide coverage loudspeakers with an incredible high output to size ratio. The TRX3903 is an ultra-compact column array element. Each column element consist of nine 3-inch high performance drivers with a 120 degree horizontal coverage. The CDD™ (CONSTANT DELIVERY DISPERSION™) technology used in TRx3903 produces a smooth linear phase response from 160Hz to 18kHz, and uniformly projects clear sound from up close and to the back of the room. For optimum performance, two column elements arrayed vertically per side with subs will evenly cover an area with high intelligibility and consistent SPL more effectively than conventional point-source designs. The TRx3903’s slim 5-inch width, along with integrated top and bottom pole mounts make setup quick, easy, and visually unobtrusive. These columns are designed to be used with a sub woofer at all times.

Add the optional 3903UBK U-Bracket and/or the SS7 short pole (both shown at left) for additional stacking, rigging and flying options. Add the SS15 short speaker stands for remporary or semi-permanent applications. See the "Accessories" section below.
