【GZNT 28SQ 2.8cm Dome Tweeter | A Speaker That Refines the High Frequencies in Car Audio】

When the vocals or the fine nuances of instruments sound a bit blurred, and the stock speakers don’t deliver enough treble—this is exactly what the GZNT 28SQ is worth considering.

The 2.8cm dome tweeter uses a coated silk dome and a powerful neodymium magnet. It’s designed to bring out high-frequency detail while keeping the overall impression from becoming too harsh—aiming for a natural, easy-to-listen-to sound. You may find that sounds you’ve always heard in your favorite songs—such as the breath of the vocals or the subtle ring of cymbals—become more clearly recognizable.

Another key feature is its design to suppress unwanted resonance and standing waves, thanks to the aluminum die-cast housing and chamber structure. Tweeters are a part whose sound impression can change easily depending on the mounting position and angle, as well as how they connect with the front speakers. It’s important not just to install the product, but to think through the installation and tuning so that the sound in the cabin comes together naturally.

At LOGON, we’ll review your vehicle model, the factory system, and your current audio concerns, and then sort out together whether it’s best to proceed with the tweeter alone or to consider the door speakers and mounting method as well. If it were me, I would first verify the sound in your car, then move forward with a configuration that doesn’t force anything.

If you want to change how the treble sounds or feel the vocals a little closer, try adding the GZNT 28SQ to your shortlist and consult us. Let’s think together about a sound you can enjoy comfortably, including the mounting approach.
