Hertz ML 280 [8/36] Technology

ML 500R unique feature is its acoustic radiation dipolar typology.

The absence of a back load makes membrane work in maximum symmetry, with ideal damping.

Bass response is outstanding: Fs is only 370 Hz and this is an impressive value for such a

compact component; it makes its versatility and easy use unique.

Enthusiasts and professionals believe that ribbon speakers can ensure faster transients than

traditional cone drivers thanks to their very light mobile voice coil. What they do not consider is the

delicate relation among the induction in the gap, the length of the wire into the field and the

membrane mass.

ML 500R is one of the very few isodynamic ribbon speakers with push-pull motor section and

membrane/magnet innovative geometry.

The motor structure was designed to generate a

perfectly symmetrical magnetic field for eliminating

intermodulation distortions and concentrating very

high energy in the gap. You get a speaker with 6 dB

higher efficiency than a traditional component,

extraordinary dynamics and very high thermal

dissipation.

If you want to obtain the same pressure

you get with ML 500R (93 dB 1W/1m)

from a traditional speaker (87 dB 1W/1m),

you need to use a four-time

higher power.
