Testing was conducted by a neutral third-party: Syndicate Automotive Concepts
in San Diego, a leader in the vehicle customization business.
Cliff and his team have been building show-stopping, award-winning rides for their VIP clientele for over 15 years.
Identical Crown I-T8000 power supplies were used, along with identical Fluke 87 multimeters to monitor voltage.
All the enclosures were sealed and built to the manufacturers optimal performance specifications.
The Test was designed to simulate real world usage. Test tones are for engineers. Music is for hardcore enthusiasts.
The signal used must be clean, with no distortion or clipping – the same bass track was utilized throughout the test.
The enclosures were sealed and were built to the manufacturers’ recommended size. All power tests were based on Re of voice coil or nominal impedance.
All testing was completed with the subwoofers in the enclosures: The Orion Test box is sealed w/ .9 cu. ft of airspace.
Matching Fluke 87 multimeters were used to read and verify peaks in RMS Voltage.
The following is a summary of the test results with voltages, impedances and peak music power.
The JL was tested at 94.5 V RMS Peak Music Power or 2976.75 W Peak Music Power at 3 ohms voice coil resistance. The W7 is only available in 3 Ohm.
The music track used for testing is approximately 3 minutes long and is repeated throughout the test cycle. Over half of the 3 minute track is below 1000 W and there are six peaks that are above 90 V and near 3000 W peak music power.
