【ESB9000 NOVEMIRA 9.1T-28｜28mm Silk Dome Tweeter】

This is the ESB9000 NOVEMIRA Silk Dome Tweeter 9.1T-28, designed for those who want to hear the finer details and nuances of vocals and instruments a little more clearly by replacing the factory tweeters.

It features a newly developed 28mm silk dome diaphragm made with pure Japanese silk materials. The TCA system controls the diaphragm’s back pressure, while the FCA system arranges the airflow around the diaphragm. Its construction makes it easier to respond honestly to the input signal—down to the fine attack characteristics and the lingering decay.

This tweeter doesn’t just make the sound brighter. It aims to naturally bring out information contained in the songs you already listen to—such as the breath in vocal performances, guitar strings, and the resonance of cymbals. I think it’s the kind of tweeter suited to that direction. For people who listen to music for long periods, it’s a unit you’ll want to combine while balancing listenability rather than chasing only high-intensity stimulation.

The face plate also functions as an acoustic lens and is designed to suppress lateral sound disturbances that are common in car audio environments. It comes with a large-diameter stainless-steel ring and an aluminum mounting case as well, so you can get everything finished properly, including the installation method.

Even with the same product, tweeter impressions change depending on the orientation, height, mounting method, and how it connects with other speakers. At LOGON, we perform installation and tuning with the car model, factory system, and your current speaker configuration in mind—considering not only that the sound won’t come out too strong, but also that the vocals will be gathered naturally in the right position.

If you want to make the high frequencies a bit cleaner or increase the amount of information while taking advantage of the sound of the factory speakers, let’s decide the direction together while talking about how you use your car and your preferences.
