The JV80 Loudspeaker SystE - M - Over the years, we have published a number of do-it-yourself speakers but the JV60 has easily been the most popular and long-lived. Now there is this new system, still using Vifa speakers but with bigger (8-inch) woofers and a teensy little Vifa D26 dome tweeter.

Yet it does it easily, due to some fancy technology which we'll get to in a moment. __ Phil Routley, SiliconChip
