Hertz MLK 2 [7/36] Technology

ML280 signature

Parameters selection and quality control are very important to HERTZ production. Every

component is subjected to several quality controls along the whole production line and it is then

selected according to strict criteria and very small tolerances.

To satisfy the needs of the most demanding enthusiasts, HERTZ worked out a very precise,

selective matching process for ML 280 tweeters.

ML 280 Signature components are chosen at the end of the production process through an

analysis which evaluates their performance in the domain of time and of frequency. The data are

recorded in a special database which analyses their performance and couples the pieces

according to their serial number.

The result is a packaging which contains a pair of identical tweeters, able to ensure state-of-the-

art performance in state-of-the-art systems.

Every element of a speaker contributes to sound reproduction. The basket supports mobile voice

coil and magnet and takes part in acoustic emission through its own vibrations and through the

reflections generated by its back arms. The mechanical resonances of a traditional basket, usually

between 800 and 1300 Hz (according to mass and stiffness), absorbe precious energy which

should be transferred only to the membrane.

ML 1600 basket is totally new and completely inert thanks to its self-

standing design and to the use of a light, damped aluminium

alloy. Its acoustic transparency is state-of-the-art and sound

is more natural, completely colorless and accurate.

The look of this speaker is incredibly thrilling and

innovative.

The same considerations and reflections made for ML 1600 new basket were made when

designing ML 280 housing and ML 500R face plate. The membrane is the only element of a

speaker which must play. Utmost attention was paid to the elimination of any resonance which

might spoil acoustic performance.

ML 280 whole structure is made of aluminium, milled through numerical control equipment, while

ML 500R face plate is made of first quality die-cast aluminium alloy.

These workings generate completely inert structures, allowing the membrane to change the

smallest, most delicate sound tones into acoustic energy.
