【Separate 2-Way Speaker Tuned with a DSP Amplifier｜3.16 MK III + 3.28 MK II Tweeter】

Designed for those who want to upgrade from the factory speakers to improve sound definition and the ease of hearing vocals, this separate 2-way speaker system using a 3.16 MK III Mid Bass and a 3.28 MK II Tweeter.

The woofer features a black anodized aluminum diaphragm and a high-rigidity steel basket. The tweeter is paired with the high-resolution 3.28 MK II. By reworking the driver assembly, it achieves both solid mid-bass and fast, responsive sound. The configuration is easy to tune into a clear, tight sound—down to the contours of vocals and the subtle expressions of musical instruments.

Since this model is specified as not using a passive crossover, it must be installed in combination with a DSP amplifier. Rather than simply connecting it like a typical speaker replacement, the key feature is that the DSP amplifier allows you to fine-tune each speaker’s frequency range and volume balance.

In a vehicle, even the same speakers can sound different depending on the installation method, how the door is treated, the tweeter orientation, and the DSP adjustment settings. Whether you want to make use of the factory navigation, increase the amount of sonic information, or bring vocals naturally forward—it's important to plan the combination based on the vehicle model, your current system, and the music you usually listen to.

Built with a high-rigidity design compatible with the EURO-DIN standard, it also considers installation flexibility. As optional parts, it supports an aluminum inner baffle ES-T09AL and a silicone waterproof cover ES-FSP-65.

If it were me, I would choose this speaker not for a standalone swap, but with the assumption that we’ll tune the overall sound in your car—including using a DSP amplifier. By not only installing the product, but also building the right foundation and making adjustments tailored to your vehicle, you can aim for a finishing touch that lets you enjoy your usual music more precisely and comfortably.
