Hi guys just looking for some input, I have to make a choice of which path to take on my bass setup. My 2 options are 1 first model Cerwin Vega 15" DVC stroker or 2 old single voice coil Rockford Power series 15" subs. I will be running either on around 600-700w rms, it's my daily driver so looking for good SQ but have good head shaking, throat tickling output.
