Hertz Dieci DBA 201

A solid MDF enclosure houses a powerful 8" subwoofer and two passive radiators for maximum sub-bass. An internal 220-watt (continuous) 0.4-ohm amplifier makes this unit highly efficient, while onboard 24 dB/octave filtering offers adjustment from 50 - 150 Hz.

0–180° phase adjustment and subsonic filter add additional tuning options as well as protection from over-excursion of the cone.

A 0–6 dB level adjustment is provided, as is a 0–15 dB wired level control.
