Incredibly high production standards on these Danish subs now discontinued but worth keeping an eye out for. 60 watt peak rms amp 8" textured paper cone circuit protection 35-150hz 108db spl means when properly tuned and balanced bass is effortless, smooth and plentiful with phase adjustment a cabinet built like a tank and good feet. Approximately 370x270x420 and 11.5 kg of value.

Superceded by C8 with very similar specs but auto power off after 15mins of no signal is $800 so I think they are a bit expensive but I got mine second hand for $80 but don't see much on ebay under $300-500 used.
