【BLAM SIGNATURE MULTIX Barrel MB6P+AMT 1 BK｜Separate 2-Way Speakers】

These BLAM SIGNATURE series separate 2-way speakers are designed for those who want to enjoy the sound a step further—replacing the factory speakers to enhance the presence of the vocals and reveal even the fine nuances of instruments.

Multix Barrel MB6P is a 165mm mid-bass unit. It uses a multi-magnet configuration and features an aluminum frame that remains compact while also being designed for rigidity. Even when listening at higher volumes, the design aims for stable playback while firmly supporting the speaker.

The high-frequency section is handled by AMT 1 BK, which employs an Air Motion Transformer. Using a different approach from typical tweeters, it is intended to express delicate details—such as the upper vocal range and fine sounds like cymbals—with greater sensitivity. In combination with the mid-bass, this setup increases the amount of musical information, allowing you to enjoy the entire music in a more three-dimensional way.

However, for a speaker in this class, simply swapping the units doesn’t necessarily bring out its true potential. The final impression can change depending on factors such as the door-side mounting base and vibration damping, installation position, how it is connected to the factory system, the orientation of the tweeter, and how the passive crossover is set up.

If I were choosing, I would first check the vehicle’s factory audio and the current installation details, then organize whether to proceed with only the speakers or to consider including door-side work and even the amplifier/DSP. Because these are high-performance speakers, I’d want to select a model that includes the proper installation and tuning tailored to the vehicle.

This is a made-to-order product. Depending on the vehicle model and the specifications of the factory audio, the installation method and the required modifications may vary. When considering this purchase, please tell us how you use your car, what music you often listen to, and what you currently feel is unsatisfactory about your sound. Let’s not force the configuration—let’s look together for the best direction while viewing the actual vehicle.
