【165S100MG Passive Included Rear Separate 2-Way｜High-Quality Car Audio Speaker】

If you want a bit more thickness in the sound from your factory rear speakers, or if you’d like to enjoy vocals and instrument sounds clearly even from the back seats, this is a separate 2-way speaker for the rear.

The 165mm woofer uses a carbon-fiber cone to enhance the sound’s attack and the expressiveness of the mid-to-low frequencies. Vocals’ contours and instruments such as guitar and piano are less likely to get buried, creating a setup that makes it easier to feel the amount of musical information even from the rear seats.

The tweeter features a 25mm pure magnesium dome. It’s well suited for those who want to hear fine details clearly, as it makes it easier to reproduce high-frequency extension and a sense of air. This is a speaker whose sonic character is easy to perceive not only when you turn up the volume, but also when you enjoy music at everyday listening levels.

The included BFX 02 audio-grade passive crossover lets you adjust the tweeter level in the range of ±3dB while separating the roles of the woofer and tweeter. Being able to fine-tune according to how the sound resonates inside the cabin and the balance with the front speakers is one of the strengths unique to a separate 2-way setup.

How the Finish of Rear Speakers Changes with Installation

Even with the same product, how a speaker sounds can vary depending on the mounting method and the vehicle’s condition. Especially when used as rear speakers, it’s important to consider the volume balance with the front side, the tweeter orientation, and the crossover adjustment.

At LOGON, we install with the goal of achieving a natural sonic unity where only the rear doesn’t stand out too much—while confirming the vehicle model, the configuration of the factory audio system, the types of music you typically listen to, and your preferences for sound between the front and rear. If you’re choosing high-quality speakers, we want to finish them together not just by installing them, but by bringing them to a point where you can enjoy them comfortably inside the car.

If you’re considering replacing your rear speakers but are unsure about the combination with your front speakers or the mounting position of the tweeters, let’s decide together by consulting while taking your specific vehicle into account.
