ESX subwoofer

The right size depends on the available mounting space — measure it beforehand and allow at least 5 cm of clearance for ventilation. Compact 16.5 cm models are suited to tight spaces, while 30 cm subwoofers like the DBX300Q deliver more low-bass punch. ESX Quantum models require only shallow enclosure depths and often fit under seats or into narrow ported enclosures.

The RMS power you need depends on your sound preferences and your amplifier. For subtle bass, 100-300 watts is enough, while competition systems often require more than 1,000 watts RMS. Make sure the subwoofer and amplifier are well matched — dual voice coil systems with 2 ohms give you flexible wiring options.

Active models such as the Q800A or V1100A have a built-in amplifier and are especially easy to integrate into your car audio system. Passive subwoofers need an external ESX amplifier, but offer more flexibility when it comes to matching power output and are often more budget-friendly.

The Quantum series stands out with high-quality voice coils, robust cones, and precise tuning. These subwoofers offer excellent power handling and deliver distortion-free sound even at high volumes — ideal for demanding audio enthusiasts and competition participants.

ESX Vision subwoofers are optimized for various enclosure types. Most models work in both sealed and ported enclosures — you'll find the exact specifications in the technical data. Many Vision models require only shallow enclosure depths, offering flexible installation options.

When combining multiple subwoofers, make sure to use identical models and calculate the impedance correctly. Dual voice coil systems with 2 ohms offer various wiring options. The total impedance must match your amplifier — our team in Pommelsbrunn is happy to advise you on the optimal configuration.
