ESX SXE10D2

The ESX SIGNUM SXE10D2 is a powerful 25-cm subwoofer that stands out for its high-quality construction, powerful drive, and impressive bass reproduction. The subwoofer truly comes into its own in bass-reflex enclosures, delivering powerful, precise low-frequency reproduction.

The sturdy die-cast aluminum basket offers high torsional rigidity and reduces unwanted resonance. The cup-shaped paper cone, combined with the durable Nomex suspension, ensures controlled cone movement. A powerful dual-magnet system with a 50-mm dual voice coil and generous winding height provides the necessary drive.

Thanks to its two 2-ohm voice coils, the subwoofer can be flexibly configured for a total impedance of either 1 or 4 ohms. This makes the SXE10D2 suitable for a variety of amplifier configurations. The pre-installed metal protective grille with its distinctive honeycomb pattern reliably protects the cone from external damage.
