【ESB9000 NOVEMIRA Silk Dome Tweeter 9.1T-25｜A Speaker for Enjoying Clear, Airy Highs】

Vocals sound a bit muffled, and the fine details of cymbals and string instruments can get buried. In such cases, rethinking your tweeter choice can be effective.

ESB9000 NOVEMIRA 9.1T-25 is a tweeter designed for high-frequency reproduction, featuring a 25mm silk dome diaphragm. By molding a silk material impregnated with resin together as one with the edge section, it achieves a lightweight diaphragm. With an easy, light transient response, this model is well suited to shaping vocals and even the subtle nuances of instruments into a clean, well-resolved sound.

Its key feature is its ability to target clear, high-resolution highs with the gentle softness characteristic of a silk dome. Not only does it brighten the sound, but by also optimizing how it connects with your front speakers and subwoofer, you can aim for a listening impression where the amount of musical information you’re used to seems to increase naturally.

For the magnetic circuit, it uses a 25mm lightweight voice coil with copper-clad winding, along with an N52H high-grade neodymium magnet. The bottom of the pole cup is designed with 12 ventilation holes to vent the back pressure of the air generated by the diaphragm’s movement. This helps suppress unnecessary diaphragm deformation and resonance, making it easier to reproduce delicate high frequencies.

Because it comes with 8 types of mount parts, including a flush-mount, it’s easier to consider your installation options. In addition to installing in the OEM tweeter position, you can consult on installation methods matched to your vehicle model and dashboard shape.

Tweeters are components whose sound impressions can change noticeably depending on mounting position and angle. If the high frequencies are too strong, they can become fatiguing to the ears; conversely, if the position or orientation doesn’t suit, it may be difficult to take advantage of the soundstage’s spread. At LOGON, we work with you to consider both installation methods and overall sound balance while checking compatibility with your vehicle and your existing speakers.

If you’d like to bring out even more clarity in the high frequencies, or if you want a natural step up from your OEM speakers, feel free to contact us. We’ll make a reasonable, no-nonsense proposal while asking what kind of sound you want to achieve inside the car.
