In the “Tecnical” section, “Subwoofer construction”, you can download the “Enclosure Design” developed by Hertz R&D to achive the best performance from ES.5 Subs.
The Hertz Energy.5 line offers the widest subwoofer range within the Hertz catalogue, boasting nine speaker models; three of them are Flat, and now five sub boxes add to them, for a really complete product offer, to satisfy any needs!
Thanks to the advanced FEA – Finite Element Analysis- simulation design techniques and the constant support of the Klippel R&D system, the Energy.5 subwoofers provide extraordinary performance with extreme dynamics and SPL never achieved in this category of the market.
In the Energy.5 subwoofers the most important improvement has been obtained by adopting the Hertz V-cone® technology which remarkably increased efficiency, in some models up to a +2dB compared to the previous series.
Thanks to their new surround and spider geometry, as well as the selection of the materials used, the new ES subs provide unmatched mechanical, and thus also acoustical, linearity.
ES F30.5, a 12” (300 mm), adding to the already appreciated ES F20.5 and ES F25.5, widens the Energy.5 Flat product offer.
Solid, powerful bass, with a unique look: the Energy.5 subwoofers are the perfect choice for those who look for thrilling performance.
All technical specifications of the new Energy.5 subwoofers are available in the “Products” section.
