### ⭐⭐⭐⭐⭐ Thumping bass tube - awesome!
*by T***S on 15 March 2021*

Great sub connected it up yesterday to a pioneer amp and sounds fab. You don’t need anything else but this unless competing. Yes it’s big but that helps deliver the thumping bass. Build is good, and looks awesome. Thoroughly recommend.
