Description
The JMF Audio HPM 400 is a very high end 2.5 ways loudspeaker.
Its woofers feature exceptionally light and ‘free’ hanging mobile equipment. Its magnetic potential is probably the highest in the world and its mechanics the quietest (for a woofer of this size).
Controlled dispersion horn and high current withstand, linear phase-controlled separation filters. Filters are probably the biggest and heaviest models for a two-way speaker.
HTS woofers
Sus woofers 30HTS200 de 12″ con núcleo magnético de neodimio y cono de fibra de carbono cuentan con sistemas móviles excepcionalmente ligeros con suspensión libre. Su potencial magnético es probablemente el más alto del mundo y su mecánica la más silenciosa (para un woofer de este tamaño).
