Taking a nod from the tuner set, Pioneer has announced a new four-stage structure for its full-range of car audio offerings. The idea is to make choosing, matching, and upgrading car audio components easier for the layman by simplifying the way they are organized.
Simply put, in the same way that a Stage 3 turbo kit is clearly better than a Stage 2, Pioneer's Stage 4 audio components should be clearly better than Stages 3, 2, and 1, and should produce best results when paired with other Stage 4 components. This simple system should keep users from, for example, unintentionally pairing a top-of-the-line amplifier with an entry-level subwoofer or from accidentally "upgrading" to a lower quality component.
Pioneer's Stage system will eventually span the manufacturer's entire line of car audio components, including receivers, amplifiers, speakers, and subs, starting with a new Stage 4 line of reference components. This new line will include the DEX-P99RS single-CD tuner and digital media player (pictured above), four new amplifiers (two full-range units and two mono subwoofer amps), two component speaker packages with audiophile quality crossovers, and a new 10-inch TS-W252PRS subwoofer.
