Fohhn Self-powered subwoofer, black



The self-powered subwoofer XS-4 – it is the lightest in it's class.


Extremely powerful 18“ subwoofer, state-of-the-art Neodym technology, extremely lightweight as a result and at only 39kg, as lightweight as a conventional 15“ subwoofer. Integral 1500W CLASS D digital amplifier and Fohhn Audio DSPs. The active Sub can be combined with all Fohhn Top speakers.A corresponding preset is available for each Top. Access to the Fohhn Audio DSP functions such as presets, equalisers etc. via a user-friendly 4-line display direct on the active Sub or via a remote control/laptop. Software is included. Transport cover with wheels is also available to protect the electronics system. Recessed transport handles allow for extremely good handling. Outstanding manufacturing quality „Made in Germany“.



Features:

- 18“ long excursion speaker

- Digital class D stereo amplifier (1500W) and 2 integral DSPs

- 2 ergonomic, deep-set handles

- wheel board (electrical system protected during transport)

- 20mm flange for spacer

Fohhn® Mains Control – the integrated mains supply monitoring system

During use, the supply to the amplifier is constantly monitored. If at any time it exceeds the maximum permitted range (180-255 VAC), the supply will be interrupted. During power up it also minimizes the input surge current by switching on at the mains voltage zero crossing.

Top speakers: all models of Fohhn Top can be used in combination with the self-powered sub XS-4 i.e. Xperience Top speakers such as the XT-1, XT-2 or XT-3ND. This also includes the new XT-33 (12“/1“CD, 500W), XT-4 (12“/1,4“CD, 500W) and the XT-5 (15“/1,4“ CD, 600W) Tops. Even speakers from the RoadLine and Perform series and EasySat series can be used in combination with the active XS-4 without a second thought. A perfectly adapted preset is available for each speaker type. This preset can be activated quickly and easily at the press of a button. The speaker is protected by complex 3-band processing for bass/mid and high frequencies.



More lightweight and powerful thanks to state-of-the-art Neodym technology.

The XS-4 active bass and the new XT-33, XT-4 and XT-5 Top speakers are fully equipped with the latest Neodym speakers and are therefore extremely lightweight. The most impressive aspect of the speakers is that all housings are manufactured from high quality multiplex beech wood and not plastic. The clear reduction in weight compared to conventional systems results from the use of state-of-the-art digital technology and Neodym speakers.Users also benefit from a reduction in weight and transport space because they no longer need to transport extra equipment and racks to venues. External amplifiers, controllers, crossovers, equalisers and similar equipment are no longer required.



Practical system combinations

Basic version: 1 x XS-4 active sub and 2 x XT-33 (12“/1“CD) Neodym speakers. Ideal for sound reproduction for bands, DJs, entertainers and at shows and galas. Fits easily in passenger cars and offers high power reserves. Plug & Play. Power version: 2 x XS-4 active subs in bridge mode and 2 x XT-4 (12“/1.4“CD) or XT-5 (15“/1.4“ CD, 600W). The XT-5 is fitted with extremely powerful Neodym components. The 3.5“ high-frequency driver has considerable power reserves and produces an impressive, refined sound in combination with the specially developed 1.4“ aluminium CD horn. The powerful sound the system produces makes it extremely suitable for shows and parties. System output: 3000W. Larger systems: The system can be extended to include any number of active subwoofers with a corresponding number of Top speakers and of course can be combined with large horn-loaded systems from the Perform series.



Easy to operate

A control panel with a blue, four-line LCD display is integrated in the active Sub so that users can adjust and view the DSP functions. The system's network compatibility and remote control options via a laptop provide you with assistance while you work. For connecting the active Sub to a PC the Fohhn-Net Adaptor NA-1 is necessary.
