Selah Audio Julietta Line Array

During the design stage we looked at various materials that had excellent sound characteristics and high aethestetic values. The result is the latest technology available including Scan-Speak Illuminator midbass drivers, RAAL ribbon tweeters, and Seas woofers. The crossover is provided by a DEQX unit which enabled us to attain a performance level not possible with a passive crossover. Other DSP crossovers can be used as well and we can program your unit at our facility or in your listening room. Six channels of amplification are required for this 3-way design. The upper section features a dipole section of eight woofers as seen here... Carbon fiber rods extend the full length of the dipole section and are connected to bamboo plywood rings. The result is a very stiff, strong, and inert frame for mechanical stability and low coloration. Both the front and back side of the array section are laminated with carbon fiber over a baltic birch plywood core. The array section is anchored by a Seas 10" subwoofer in a sealed cabinet. The woofer has a stiff aluminum cone and very low distortion motor designed with the help of the Klippel test system. The woofer is unique in that has very extended upper end response which is critical to optimal integration with the line array section. The specifications for the response are dependent upon the DSP unit being used. With the DEQX unit we achieved 30hz-20K at +/-1db. Sensitivity is 88db and impedance 4 ohms. We can configure the system for a higher impedance if desired for OTL and SET owners.
