【PRS-165.3 Separate 3-Way Speakers｜A Three-Dimensional Soundstage and Delicate Vocal Playback】

After replacing the factory speakers, you may want to hear the vocal positions and the subtle nuances of instruments a bit more clearly. You want solid bass, but you don’t want sound that’s just louder in quantity.

For people like that, the PRS-165.3 Separate 3-Way Speakers are a great fit.

With a 3-way configuration that separates the tweeter, midrange, and mid-bass, each frequency range plays its own role. Vocals are led primarily by the 80mm midrange, rising up naturally, while midrange instruments such as guitars and pianos are presented in a cleaner, more organized way—without overlapping too much.

The 19mm silk-dome tweeter handling the high frequencies is known for its flexible sound that doesn’t become harsh. Even if you listen to music for long periods, high-frequency stimulation is less likely to bother you, so you can enjoy the vocalist’s breath and the lingering resonance of instruments calmly.

The 160mm mid-bass responsible for the low end uses a 3-layer structured glass-fiber paper cone. Designed with emphasis on not only the power of the bass, but also its rise time and how it settles, it offers not just the kind of volume you expect from door speakers, but also a sense of rhythmic tightness that’s easy to feel.

Sound Separation Like Only 3-Way Can Deliver

The included passive network is designed to split the tweeter and midrange bands. It uses a 12dB/oct filter for the tweeter and a 6dB/oct filter for the mid-bass, allowing each speaker to reproduce its assigned frequency range without strain.

Not only is it enjoyable with a standard passive connection, it also supports multi-amping/multi-connection using a 4ch amplifier. It’s also suitable for those who want to make fine adjustments to match the vehicle’s acoustic environment by combining with an amplifier and/or DSP.

The tweeter is also equipped with an attenuator that can switch the level between +3dB and 0dB. Since how the high frequencies are heard changes depending on the mounting position and reflections inside the cabin, being able to adjust while actually checking the sound is a welcome feature.

The Sound Impression Changes with the Installation Method

Even with 3-way speakers, simply swapping in the units doesn’t guarantee that their original strengths will be fully realized.

Especially the midrange: the cohesiveness of the sound changes depending on the installation location and the surrounding volume. With the PRS-165.3, a recommended 0.4L BOX volume is set for the midrange, so it’s important to plan a configuration that can draw out performance as naturally as possible while confirming the available space on the vehicle side and the installation method.

The mid-bass also varies in how tightly the bass locks in and how it connects with the midrange, depending on the baffle that forms the base of the door, surrounding treatments, and the combination with the factory audio system. Even with the same speaker, where and how you mount it can significantly affect the final impression.

At LOGON, we organize whether to use a passive connection or a multi-connection with an amplifier, together with you, while checking the vehicle model, the factory system, the music you usually listen to, and your preferences for volume. If you want to think not only about choosing the speakers first, but also about the installation method and future system upgrades, please feel free to consult us.

When you listen to your usual tracks, the vocals feel slightly more forward and the overlapping of sounds becomes more neatly organized. The bass rhythm becomes easier to follow, and the time spent listening to music in the car naturally becomes more enjoyable. The PRS-165.3 is a separate 3-way speaker designed to make these kinds of changes easier to achieve.
