Mint condition Dali Helicon 600 subwoofer in gloss cherry finish. Great sound on its own, and can be added to the Helicon 400s and 200 center channel (please see those ads). Some specifications: bass drivers 2 X 12 inch long throw, sensitivity SPL/m/2.83V, 117dB output, nominal impedance 20K ohms, integrated sub amplifier internal 300 watts, frequency range 25Hz to 175Hz, magnetically shielded, sub enclosure type infinite baffle.
Two of the photos show the 600 subwoofer with the 200 center channel on top-- the 600 was specifically designed to act as a "cradle" for the 200, if desired.
Please let me know if you have any questions about this subwoofer.
