What is Pioneer P.R.O.
In the early 2000s, an SPL competition called “dB drag racing” became popular in the U.S. By 2003, there were approximately 10,000 competitors, with winners achieving around 150dB. Pioneer broke the world record in 2004 by reaching 173.0dB and renewed this title the following year with an impressive 180.5dB!
Around 2005, under the sponsorship of the IASCA (International Auto Sound Challenge Association), an emerging SPL competition called "OPEN SHOW" was introduced with great success. The acronym for Pioneer P.R.O. (Pioneer Reference for Open Show) for our dedicated products comes from this designation.
Now, it's a trend that can also be enjoyed casually outdoors, whether partying or tailgating at your favorite sports event.
Large and Heavy
Specifically crafted for open show car audio systems, these speakers exemplify phenomenal maximum power and incredible efficiency, allowing not only high sound pressure (SPL) but also hours of musical enjoyment. The basket and the imposing motor structure of this speaker, which uses a heavy magnet, offer all the required power handling and heat dissipation to move the main cone and its large aluminum voice coil.
Paper Beats Rock
The optimally blended pulp cone woofer guarantees precise and vibrant sound, while the motor construction, voice coil, and powerful magnet. Drawing inspiration from Pioneer's history in SPL competitions, promise high efficiency and excellent thermal management, even at high volumes.
Aluminum Ring and Bullet
A large bullet-shaped waveguide, made of die-cast aluminum, not only provides better thermal management for high-power handling but also allows for greater acoustic propagation and dispersion. To maintain sound quality even at high power and excursion, this speaker incorporates an aluminum reinforcement ring at the junction of the cone and the voice coil support. This reinforcement stiffens the critical junction and reduces the distortion typically generated under high excursions.
