Locke auto time subwoofer works well, with high cost performance. It is a very good choice for some friends who don't want to spend a lot of money to modify it. Its appearance is fashionable and upscale, and its sound quality is good.

in Locke's era, the power was a little low, only 25w for a 12-inch subwoofer. Now many 1-inch subwoofers can achieve 1w eight ohms, so the dynamics and low frequency of this subwoofer are relatively limited.
