### ⭐⭐⭐⭐⭐ Amazing for a 12 and the K212C has very little low end directly behind them... by design
*by C***R on July 14, 2022*

This speaker has not failed me.. Amazing in its performance. The only failure I have seen is that I would like to buy another and since COVID there has not been any available. Either the company stopped making them or the supply chain has stopped moving them. Anyways,, you find one,, you should get one.
