Dayton Audio ND65-4 2-1/2" Full Range Driver

By: on 22 September 2016
After reading the information on the web site I had high hopes for this tiny little speaker driver. They were exceeded. The application is a Bluetooth enabled active speaker and the results are extraordinary. It really does perform better than many speakers twice its size.
