【For Pioneer Z900PRS｜Custom Fabrication of Large Tweeter Embedded Flocked A-Pillar】

If you choose the Pioneer Z900PRS in a 2-speaker setup, where and at what angle you mount the tweeters will greatly affect how well the sound comes together.

So we embed the Z900PRS large tweeters into the A-pillars and finish the surface with a flocked texture. While not dramatically changing the OEM look and feel, we achieve both a design that naturally fits the interior and mounting positioning that helps bring the sound forward.

A-Pillar Fabrication to Dial In Sound Position

When the tweeter height or angle changes, the vocal position, the definition of instruments, and the way the soundstage spreads will also change.

To take advantage of the fine detail the Z900PRS can provide, it’s important not only to install the large tweeters, but also to determine their position based on how they sound from the driver’s and passenger’s seats and on the interior shape of the vehicle.

With proper positioning, the vocals won’t get buried deep behind the dashboard, and you can get closer to a focused, “singing right in front of you” kind of sound. Instrument notes become clearer one by one, making it easier to enjoy the subtle expressions hidden within the songs you always listen to.

Keep the Look Subtle—But Push the Sound Forward Clearly

If you retrofit a large tweeter, some people may feel it stands out too much in the cabin.

With a flocked-finish A-pillar, one of its key benefits is that it helps create a sense of unity with the factory interior while keeping the surface texture calm and understated. It doesn’t demand attention visually; yet when you play music, the front stage naturally “floats” forward. That’s the goal of this fabrication.

Even with a 2-speaker setup, if you carefully dial in the mounting position and sound tuning, you can enjoy dense, three-dimensional music—not relying only on the number of sound sources.

Decide Position and Finish According to the Vehicle

Depending on the shape of the A-pillar, the cabin space, and your driving posture, the ideal tweeter position and angle will vary. Even if you use the same Z900PRS, you can’t just mount it in the exact same way on every vehicle.

At LOGON, we confirm the vehicle condition and how the customer listens, and then fabricate with not only appearance in mind, but also how the sound comes together and overall usability. After installation, we listen to the sound in the actual cabin and adjust the overall balance.

If you’ve chosen the Z900PRS but are unsure about how to mount the tweeter or how to finish the A-pillar, tell us your vehicle model and the sound you’re aiming for. I’ll think this through with you—not only the speaker itself, but also the mounting portions like these.
