【8.6K2CX | 2-Way Passive Network for 8000 Series】

8.6K2CX is a 2-way passive network designed to match the speakers in the 8000 series.

With a configuration that prioritizes the clarity of the mid-to-high frequencies, it uses a high-quality custom capacitor and a pure copper (99.9%) air-core coil. It’s ideal for those who want to bring out vocal expression and the subtle nuances of instruments as naturally as possible.

For the adjustment jumpers, a gold-plated specification is used to suppress resistance while also handling high loads. In addition, it includes an acrylic cover designed for cooling and protection of the components. Although it’s not very visible, because it’s an audio system meant to be used for a long time, such internal attention to detail is an important factor that contributes to sound cohesion and peace of mind.

For connection, it supports switching between multi-amp connection and single-amp connection. You can choose according to your system configuration and future step-up plans. The tweeter level can also be adjusted from 0dB / -2dB / -4dB / -6dB.

You can adjust it to match the vehicle’s acoustic environment and your preferences—for example, if the treble feels a bit too strong inside the car, or conversely if you want a little more brightness. If it were me, I wouldn’t decide purely based on numbers at first; instead, I would listen in the actual vehicle, check how the vocals and cymbals come through, and then set it.

Even with the same product, the final sound of a passive network can vary depending on the mounting location, wiring treatment, and the combination with the speakers. To make the most of 8.6K2CX, it’s important to consider not only the speaker itself, but also the condition of the door side, your amplifier configuration, and your sound preferences.

If you want to drive the 8000 series speakers more carefully, develop from a single-amp setup to a multi-amp configuration, or fine-tune the tweeter’s sound so it fits the cabin, let’s decide the direction together while checking your vehicle and your current system.
