DD Audio 12" 600 Series Subwoofers

The 600 Series subwoofers are not for the faint of BASS! From the top down they are built for extreme sonic performance. Heavy duty double stack magnet motors and long throw voice coils handle the power while Power Tuned suspensions with EROM surrounds and a progressive dual spider system keep the moving parts linear and distortion free during high excursion play. The 600 Series subs work best in vented and multi order enclosures.     612E Speaker Size (In): 12 Speaker Size (MM): 304.8 Watts RMS: 500 - 800 Watts Peak: 2400 Impedance: D2 / D4 VCD (In): 2.5 Piston Diameter (In): 10.125 Fs (Hz): 32.3 Qms: 4.646 Qes: 0.472 Qts: 0.428 Vas (Liters): 40.22 Xmech (In): 2.6 Xmech (MM): N/A Xmax (MM): 15 Frame OD (In): 12.875 Frame OD w/ Gasket (In): 13 Mounting Diameter (In): 11.5 Mounting Depth (In): 6.75 Motor Diameter (In): 7 Motor Depth (In): 3 Magnet Weig
