[FOCAL SUB 30 KXE | 30 cm K2 Power Subwoofer]

Rather than just making the bass louder, this is for those who want to add depth to the entire music and create a natural connection with the front speakers. That’s exactly what the FOCAL SUB 30 KXE is designed for.

A K2 Power series subwoofer featuring a large 30 cm woofer and high power handling of 800W RMS / 1600W MAX. FOCAL’s traditional yellow K2 sandwich cone reproduces bass that has a solid core—never just quantity.

This model can reliably fill in low-frequency information that front speakers alone are often difficult to produce, such as the punch of drum kicks, the weight of bass, and the atmosphere of live recordings. It doesn’t merely make the bass stand out; by allowing the front sound to play more naturally as well, the entire mix may end up feeling easier to listen to.

Since the SUB 30 KXE uses a dual voice coil of 4Ω + 4Ω, it requires a design matched to the amplifier(s) and system configuration you plan to use. With a subwoofer, the end result changes greatly not only with the unit’s performance, but also with the enclosure volume, how you choose the amplifier, the installation method, and the tuning with the front speakers.

If it were me, I wouldn’t simply pair it with a larger amplifier. I’d confirm how much bass you want to enjoy inside the car, what kind of music you normally listen to, and how much of the trunk you want to use—then decide the configuration. The key is balance: not a system where only the bass pushes forward, but one that lets you enjoy music comfortably in the car.

If you want to step up from the SUB 25 KXE, or if you feel that the bass from the factory or an existing system is lacking, please consult us while checking your vehicle and your current system. We’ll think together about the final setup in a reasonable, stress-free way—including installation and tuning.
