When you “got to get a little more out of your audio system” and you also have to make that car payment Massive Audio has got ya covered! The NEW DT-05 add on tweeters are a 13mm hard dome (1.8”) that play from 2.5Khz-20Khz and will not break your piggy bank! Complete with surface and flush mount kits with 50 Watts Peak Power handling the DT-05 will “TOP OFF” any great system. Crossover not included with the DT-05. A 3.3uF/50v cap filter (5 Khz) will be necessary on each speaker lead if you are not using an existing crossover.
