Ultra-compact size but powerful bass. Easy to connect and can be mounted under the driver or passenger seat. Impressive sound from just 4.5 liters of total volume. This is thanks to the newly developed 20 cm bass with dual voice coil, supported by a clever electronic equalizer. This equalizer optimally channels the 200 W nominal power of the amplifier to the bass speaker. And the best part is that you can adjust the EQ to suit your personal taste. Always powerful, always punchy, the Flatsub makes most competitors in this format look pale in comparison.
