The PT-70 performs
Published: PRODUCTS
Fohhn Audio AG developed its Perform-Series, as the name suggests, for live performances. Therefore, the manufacturer looked to ensure that the newest addition to the series, the PT-70 loudspeaker, was fit for purpose in delivering concert sound and surviving touring life. Part of the extensive testing process involved putting the PT-70 to work, providing the sound reinforcement across Fohnn’s home country of Germany – at the Rantastic in Baden-Baden, the 28th Ehinger Jazztage at Jazzclub Ehingen and a performance by Axel Rudi Pell at Rockfabrik in Ludwigsburg.
A horn-loaded, passive, two-way speaker, the PT-70 has been designed to serve as a sound solution for smaller venues, indoors and out, or as an extension for larger line array or beam steering systems at larger arenas. Targeting the rental market in particular, it can also be used as a multi-functional plug and play solution.
It includes the manufacturer’s Convertible Dispersion Technology (CDT), which enables it to be manually switched between vented and cardioid operational modes. With a pair of 12-inch chassis, compression chamber and horn, as well as a 1.4-inch compression driver on the CD horn, the PT-70 possesses a passive crossover, featuring a voltage-controlled circuit and an integrated mid-range waveform system.
Two different beam dispersion angles are available: 90-degrees x 50-degrees and 60-degrees x 50-degrees. The maximum sound pressure level is 140dB, the frequency range is from 52Hz to 20kHz and the load capacity is 900W nominal, 3,600W peak. With dimensions of 400 x 850 x 450mm and a mounting bracket system designed to allow it to stand alone on a tripod or be flown, the PT-70 is built from steel brace reinforced multiplex birch plywood, coated with scratch-resistant, polyurethane black finish as standard (other RAL colours are available on request) and weighs 39kg.
