【BLAM AMT 1 BK/Gold｜Air-Motion Transformer Tweeter That Delivers High-Resolution Playback】

You want to increase the amount of information in the high-frequency range, but you’d like to avoid sharp, piercing “sizzly” sound. BLAM AMT 1 BK/Gold is the one to try.

A tweeter that uses the Air-Motion Transformer (AMT) method to efficiently move air with a lightweight pleated diaphragm. From subtle vocal nuances and the decay of instruments to the delicate details contained in high-resolution audio, it reproduces a clear, well-defined high-frequency range.

Despite offering a large radiating area, it remains compact: a mounting cutout diameter of 65.2 mm and a mounting depth of 16.6 mm. The aluminum frame is also designed with heat dissipation in mind, making it easier to consider a variety of mounting positions. With two color options—black and gold—you can choose not only for sound, but also to match the interior atmosphere and finish.

Even with the same product, the impression a tweeter gives can change depending on its orientation and mounting position, as well as how it connects with the front speakers. It’s not simply a matter of boosting the treble; it’s important to fine-tune while considering the vocal placement, the soundstage width, and how easy it is to listen to over long periods.

If I were setting it up, I’d make sure to confirm not only the speaker itself, but also the installation method and compatibility with your existing system, so you can get the most out of the BLAM AMT 1. Let’s find together the direction that naturally comes together inside your car—by actually listening to the songs you always play.
