【BLAM SR 165 S | 16.5cm separate speakers to enjoy natural sound cohesion】

You want to replace the factory speakers so that you can hear vocals and instruments a bit closer and more clearly. But you’d like to avoid making the sound too flashy or letting the treble turn harsh.

That’s where the BLAM Super Relax SR 165 S comes in.

With a separate 2-way setup that combines a 16.5cm woofer and a 20mm soft-dome tweeter, this model makes it easy to bring out the natural sense of soundstage and vocal presence. Whether you want to enjoy your usual music with a slightly higher volume or listen slowly on long drives, I think these speakers are designed to achieve a cohesive sound that’s less likely to feel piercing in your ears.

The woofer uses a treated cellulose pulp diaphragm and a butyl suspension. While supporting sound from the low to the midrange, it also helps shape vocals, guitars, pianos, and more so they’re easier to pick out. Since you can adjust the tweeter level on the crossover side, it’s also a plus that you can match the treble output to the reflections inside the cabin and to your personal preferences.

That said, simply replacing the speakers doesn’t automatically determine how good they can sound. Depending on the condition of the door, the installation method, the baffle, damping treatment, and the compatibility with your factory audio, the impression you get can be different even with the same product.

If it were me, I’d first confirm your vehicle model and the factory system, then consider how much work is needed to make the most of the strengths of the SR 165 S. Rather than expanding the installation scope more than necessary, we’d go over it together based on the music you usually listen to, your sound preferences, and your budget—whether to proceed with speaker replacement only, or whether to carry out treatment on the door side as well.

These speakers are a good choice for those who feel a bit unsatisfied with the sound of their factory speakers, those who want to hear vocals a little more closely, and those who prefer natural, easy-to-listen-to sound over more aggressive tonal character. Please enjoy how your everyday tracks will change when installation and tuning are tailored to your car.
