Cool down the voice coil is necessary for high power handling speakers, such as professional application, or demanding subwoofer. The well known solution (high temperature material for the former, bigger wire section, ...) limit the performances because it increases the weight of the moving mass. We have developed different approach using specific speaker parts as cooling radiator. Instead of using robust but heavy material to support high temperature, we transfer it to the environment. The heat doesn't affect the loudspeaker basically because it is dissipated. Here below, we measure how the temperature increase on our very compact Subwoofer "Sub120_vHE" when we use the Kooling device. We see than Kooling system allows to keep the voice coil 40°K lower than same product without Kooling system. Note: This demanding measurement uses high power signal around the Fs[Hz] during 500s.

Ensure soft part venting without any air flow noise

- Manage the air flow in the speaker is important to cool down the voice coil, and avoid any inner resonation.
- Nevertheless, for the speakers with high cone excursion, keep the air flow quiet in any situation is challenging; noises happen in the air flow with air speed variation.
- We have developed special items, strategically located to manage the air flow and keep its speed constant.
- As a result, our speakers keep quiet working, without any air flow noise, even during the highest cone excursion.
