【165S100MGA Passive-Free Separate 2-Way Speakers｜Serious Car Audio That Balances Power and Fine Detail】

If you feel your factory speakers sound a little underwhelming, want to hear vocals and instruments more clearly, and want to enjoy playback with plenty of headroom even when you turn the volume up—then the 165S100MGA Passive-Free Separate 2-Way Speakers are worth considering.

The 165mm woofer uses a carbon-fiber cone. Built to handle fairly large input levels, it pushes out strong sound from the low end through the midrange. You’ll also find it easier to perceive the core of vocals and the attack of instruments like guitar and piano, making it a good choice for anyone who wants to enjoy the music they already listen to a little closer and more realistically.

The tweeter is a 25mm pure magnesium dome. Rather than simply making the highs brighter, it’s designed to bring out fine audio details and even the sense of airiness. By pairing the woofer on the door side with the tweeter near the dashboard, you can aim for a soundstage that doesn’t bunch up at your feet and instead spreads forward.

This model is a configuration that does not include a passive crossover. As a result, you’ll need connections and adjustments tailored to your vehicle’s system, such as using a DSP and/or external networks. While the flexibility is high, it’s also a speaker whose full potential can be hard to realize with a simple swap alone.

At LOGON, we design a reasonable system configuration while checking details such as your vehicle model and the specifications of the factory audio, whether you have an amplifier, the condition of the doors, and the mounting position of the tweeters. Not only speaker performance, but also building a solid foundation on the door side, choosing the right installation angle, and aligning the sound connection points will change the balance between power and ease of listening.

If it were me, I would recommend these speakers more for those who want to enjoy not just loudness, but also the sound’s attack and spatial presentation—using an external amplifier and/or a DSP. Because the best connection method depends on your vehicle’s system, if you’re considering installation, let’s decide the direction together while reviewing your current audio setup.
