This one is ambitious on price for a compact used sub. At US$535, it lands above the 75th percentile of recent comparable listings (US$532) and well over the median of US$350, so it’s asking top-of-market money rather than a normal fair ask.
That said, the SuperCube line is well regarded for delivering serious bass from a very small footprint, which is the whole appeal here. If it’s clean, fully functional, and includes the original amp and controls, the premium is easier to justify for someone prioritizing size and output over raw value. I’d still want proof it powers up quietly and plays strong at low and high levels, since older powered subs are most vulnerable in the amp section.
