Fohhn PT-70 Top - Cardioid High Performance Speakers, 90x50
Fohhn Cardioid High Performance Speakers, 90x50
Horn-loaded. Cardioid. Plug & Play.
Fohhn expands its Perform-Series with the PT-70 – a high performance, 2-way loudspeaker system with cardioid functionality that has been specially developed for concert sound and touring applications. The new loudspeaker makes an ideal sound system for concerts in tents, halls and clubs, or for town festivals and smaller open-air events. It also acts as a solid extension for line arrays and large Beam Steering systems. For the rental market, the PT-70 has many applications as a multifunctional loudspeaker system. The PT-70 contains two 12“ chassis with compression chamber and horn, plus a 1.4“ compression driver with CD horn. It features a passive crossover which splits up the loudspeaker's audio signal. An Intelligent Protection Circuit (IPC), a voltage-controlled semiconductor circuit, protects the high frequency driver from overload - quickly and reliably. The loudspeaker system also features Convertible Dispersion Technology (CDT), which is registered as a utility model. This technology enables the PT-70 to be switched between cardioid and vented operation. In cardioid mode, the sound dispersion at low-mid range frequencies is effectively reduced at the system's back. Thus first-class sound reproduction and speech intelligibility are ensured. The PT-70 has been solely developed for operation with Fohhn speaker presets - especially with Fohhn Class D amplifier D-2.1500: The system's equalizing occurs within the Fohhn DSP, which also includes all of the protective functions that required for a safe operation. Together with this amplifier and Fohhn subwoofers, the PT-70 delivers excellent results.

Horn-loaded, passive loudspeaker system with 2-way technology
Horn-loaded, passive loudspeaker system with 2-way technology, equipped with two 12” low-mid chassis in compression chamber, horn loaded and with a 1.4” high frequency compression driver. Fully neodymium. The loudspeaker system has a Constant Directivity Horn with a defined beam dispersion of either 90° x 50° or 60° x 50°. The system is also equipped with an integrated, phase-optimized crossover with active, semiconductor circuit (IPC technology) for high frequency driver protection. The loudspeaker system can be manually switched between cardioid and vented operation. It also has a mid-range waveguide system for suppressing unwanted side lobes in the vertical acoustic axis. The loudspeaker housing is made from multiplex birch plywood, with steel brace reinforcement and a black, scratch-resistant polyurethane coating. Can be supplied, on request, in all RAL Classic colours. Optionally available with a polyurethane coating that has an additional UV protective layer and waterproof membrane for increased protection against environmental impact, weather and mechanical wear and tear. For tripod use and flown applications, the loudspeaker system is equipped with two suspension fittings for Quicklock flying brackets and AEROQUIP rigging hardware, as well as two ring eyelets for safety. Connections: two Neutrik NL4 Speakon.
