The JMF Audio HPM 500 is a very high end 2 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.
|Weight of the moving parts||70 g|
|Resonance frequency||19 Hz|
|Total magnetic flux||416000Mx|

|Low frequency cut-off||300 Hz|
HPX high level cross-over HPX500
High current handling, linear, phase controlled cross-overs. Possibly the largest and heaviest units for two way loudspeakers.
