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.
