PT.2 PRO AUDIO FULL RANGE TWEETER It's getting more and more popular... For decades it took insane amounts of traditional car audio speakers to try to keep up with crazy amounts of bass that audio fanatics crave. PPI's new Pro Audio separates are entirely different boasting great clarity and off-the-chart efficiencies! One of these midrange will yield the same output of 4-8 regular car audio speakers! And the tweeters and horns are even more intense!
